Sugary drinks are significant drivers of obesity and diabetes.

At the 2025 Club World Cup, the world’s most celebrated footballers – from global icons to rising stars – are showcasing their elite athleticism and passion for the game. 

But as stars like Lionel Messi take center stage, there is one name that doesn’t belong anywhere near the pitch: Coca-Cola.  

Coca-Cola has partnered with global football body FIFA since 1978 and has been a ubiquitous presence at this year’s Club World Cup. FIFA’s football tournaments are a premier platform for showcasing health and fitness, while Coke is the largest global manufacturer of soft drinks, a top driver of the world’s twin epidemics: obesity and diabetes. Coca-Cola should not be sharing the spotlight with football players and using their achievements to “sportswash” away soda’s harms. 

It’s easy to see why not. Four of the five brands under Coke’s umbrella contain high levels of added sugar or artificial sweeteners. A single 20 oz bottle of Minute Maid Lemonade contains 67 grams of added sugar, over 100% of what a typical adult should consume in a day.

Liquid sugar is especially damaging. It causes dental caries, weight gain and increases many health risks. Our bodies don’t respond to liquid calories the same way as food calories: they do not make us feel full, leading us to consume more. 

Additionally, there’s increasing scientific evidence to suggest sugar is addictive: it affects the brain in a manner similar to cocaine and can lead to increasing intake, withdrawal and cravings.

The health harms of sugary drinks start young. Big Soda companies hook kids on their products through pervasive marketing tactics used in schools, during kids’ sports and on screens. As a result, over half of American children consume sugary drinks daily. And because dietary behaviors set in childhood track into adulthood, these early preferences set kids up for lifetimes of unhealthy eating. 

PepsiCo and Coca-Cola are amongst the worst plastic polluters in the world.

Big Soda also devastates our environment. Along with PepsiCo, Coke is one of the largest plastic polluters in the world. According to the University of California, per liter, soda uses 27 times more water and produces 11 times more greenhouse gas emissions than the equivalent amount of tap water.  

Yet, Big Soda has tried to frame itself as “part of the solution.” For decades, it’s promoted physical activity as a solution to obesity, ignoring data that it’s nearly impossible to out-exercise a bad diet. Beverage companies have interfered with scientific research and professional nutritional organizations, obfuscating the true health impacts of their products. And by positioning themselves as “helpful,” they have actively fought against public policies to reduce sugary drink consumption.

Along with “sports” and “health washing,” Big Soda employs “greenwashing,” or framing damaging products as helping, not harming, the environment. At the 2024 Olympic Games, where Coca-Cola was a leading sponsor, the soda giant claimed to be an environmental champion by halving the number of plastic bottles used at previous Olympics.

 While seemingly offering nine million drinks in reuseable, returnable eco-cups, 75% of these drinks came from plastic bottles poured into eco-cups. At best, this type of “greenwashing” is misleading to consumers and at worst, threatens to exacerbate the pollution crisis.

These companies also use emotion to push product sales. Coke’s 2022 World Cup advertisement featured people from around the world celebrating amid a flurry of confetti, which outwardly has nothing to do with soda. Coke chose to capitalize on the emotions the World Cup incites: hope, joy and a sense of social connection that is increasingly rare. It profits from this emotional appeal by selling us products that are harmful for our health and planet. 

Football is bigger than ever. The 2022 FIFA World Cup drew a cumulative audience of over 5 billion, with the final alone watched by 1.5 million people. With this massive reach comes increased responsibility to engage in ethical, transparent practices that don’t cause health and environmental harm. If we expect our athletes to play fair, so should FIFA. 

But the tide is turning. The Kick Big Soda Out of Sport campaign, led by global health advocates and organizations, is mounting an opposition to Big Soda’s sports sponsorships. As the 2025 Club World Cup games are being played across the U.S., the Kick Big Soda Out movement is demanding FIFA end its partnership with Coca-Cola. Over 350,000 people, alongside 97 health and environmental organizations have already pledged their support. 

The spotlight isn’t only on the players—it’s on FIFA too. Will it continue to hijack the global stage for profit, or will it take a stand for the health of fans, players and the planet? 

The facts are clear. It’s time to ban Big Soda in sport.

Luyengo Clinic in Eswatini. PEPFAR funded 80% of the clinic’s running cost, and the HIV treatment of 3,000 people is now in jeopardy.

An additional six million new HIV infections and four million AIDS-related deaths could occur between 2025 and 2029 if US-supported HIV treatment and prevention services collapse, according to UNAIDS.

“This is not just a funding gap. It’s a ticking time bomb,” said UNAIDS Executive Director Winnie Byanyima at the launch of the organisation’s 2025 global AIDS update on Thursday. 

“We have seen services vanish overnight. Health workers have been sent home. And people – especially children and key populations – are being pushed out of care.” 

“Key populations” refer to people most vulnerable to HIV infection, including sex workers, men to have sex with men, people who inject drugs and young women.

Some of the immediate effects of the US withdrawal of funds since Donald Trump assumed the presidency in January include the closure of health facilities, healthworker job losses, and disrupted treatment, testing and prevention services.

Impact of aid cuts on HIV infections and deaths

The US President’s Emergency Plan for AIDS Relief (PEPFAR) had committed $4.3 billion in bilateral support in 2025 and “those services were stopped overnight when the US government shifted its foreign assistance strategies,” notes the UNAIDS report. 

PEPFAR had supported HIV testing for 84.1 million people and HIV treatment for 20.6 million people.

“Disruptions are being felt across the HIV response and pose a huge risk of increased mortality, a surge of new HIV infections, and the development of resistance to the most commonly used treatment regimens.”

In Mozambique, for example, over 30,000 health personnel have lost their jobs.

UNAIDS itself faces huge job losses, and is reducing its Geneva head office staff from 127 to a mere 19 employees, according to a report this week by Geneva Solutions.

The UN agency’s restructuring plan will cut staff by 54% globally, leaving 280 staff worldwide. 

HIV prevention programmes hit hard

Country reliance on aid for HIV prevention.

External funding financed almost 80% of HIV prevention in sub-Saharan Africa, 66% in the Caribbean and 60% in the Middle East and North Africa, according to UNAIDS.

PEPFAR alone reached 2.3 million adolescent girls and young women with comprehensive HIV prevention services in 2024 and enabled 2.5 million people to use pre-exposure prophylaxis (PrEP). Many of these programmes have now stopped completely, according to UNAIDS. 

PrEP involves taking medication to prevent HIV infection and is usually taken by people at high risk of infection, and PEPFAR funded over 90% of PrEP initiations globally in 2024.

“Countries are reporting limited availability of PrEP and reduced activities to prevent new HIV acquisitions, including among adolescent girls and young women,” said UNAIDS.

In Nigeria, budget cuts have reduced PrEP initiation from 40,000 to 6000 people per month.

At the end of 2024, just before a sudden collapse in funding, new HIV infections had been reduced by 40% and AIDS-related deaths by 56% since 2010, Byanyima notes in the report. Countries had also reduced the annual number of children acquiring HIV from their mothers by 62% to 120,000 since 2010.

However, prevention efforts were already flatlining before the withdrawal of US aid. In 2024, there were 1.3 million new infections, which was almost the same as the year before.

“Over 210,000 girls and young women aged 15 to 24 acquired HIV in 2024 – an average of 570 new infections every day,” according to the UNAIDS report.

In 2024, 630,000 people died from AIDS-related causes, 61% of them in sub-Saharan Africa. “Community-led services, which are vital to reaching marginalised populations, are being defunded at alarming rates,” said UNAIDS.

“In early 2025, over 60% of women-led HIV organisations surveyed had lost funding or were forced to suspend services.”

Domestic budgets inadequate

Only 25 of the 60 low- and middle-income countries included in the report have increased their domestic budgets for HIV in 2026. The average increase amounts to 8%, approximately $180 million in additional domestic resources. 

“This is promising, but not sufficient to replace the scale of international funding in countries that are heavily reliant,” UNAIDS notes.

“It is important for donors to recognize that the option of increasing domestic HIV funding is not immediately or equally available to all countries,” UNAIDS notes.

“Combinations of debt distress, slow economic growth and underperforming tax systems leave many countries, notably in sub-Saharan Africa, with limited fiscal space to increase their domestic funding for HIV. “

It cites the recent International Conference on Financing for Development in Seville in Spain, as offering a way forward with “calls for debt relief, international tax cooperation and reform of international financial institutions”.

These measure would provide “the first steps towards a new economic settlement that can give countries the fiscal space needed to invest in the global HIV response”, UNAIDS notes.

“Urgent action and revived solidarity are needed to sustain the progress made and prevent a resurgence of HIV.”

Dr Joanne Liu, a veteran humanitarian and former international president of Médecins Sans Frontières (MSF), has seen the front lines of global health crises—from Ebola in West Africa to bombed-out hospitals in Afghanistan. But her message today is clear: “An imperfect solution is better than no solution.”

Speaking on the Global Health Matters podcast, Liu reflected on the values that shaped her career, the lessons learned during her years at MSF, and her call for renewed global solidarity.

“Young people come into my ER and tell me they don’t want to live any more,” she said. “They feel trapped in a cruel and unfair world. I want to convince them it’s better to fight than give up.”

In her new book, Ebola, Bombs, and Migrants, Liu recounts how fear and political interests often override humanitarian needs. She recalled how the world ignored West Africa’s Ebola crisis until the virus reached Europe and the U.S.

“States don’t have friends—they have interests,” she said.

Liu also discussed the devastating U.S. airstrike on MSF’s hospital in Kunduz, Afghanistan, which killed 42 people.

“We called everyone—the Pentagon, the UN—but no one stopped it,” she said.

The attack pushed MSF to campaign for stronger protections for medical missions.

Liu is now focused on shifting the power dynamics within global health.

“For every international staff member, there are nine or ten locally hired,” she said. “We need to rebalance who holds influence.”

Despite setbacks, Liu remains hopeful.

“There is beauty everywhere,” she said. “It’s action that brings hope, and hope that brings action.”

A trial participant is prepared for a blood test as part of a trial of new TB drugs that can overcome drug resistant pathogens. Several HIV and TB trials were suspended following recent changes in US policy.

Human trials conducted outside the United States with funding from the US National Institutes of Health (NIH) halted by the Trump administration in May, may be permitted to continue.

On 1 May, the NIH outlawed US researchers from making subawards to foreign research partners, jeopardising billions of dollars of research throughout the world. As a result, some clinical trials on humans were halted midway despite dangers to trial participants and the huge waste of money.

However, the payment freeze to several NIH subawardees in South Africa was recently lifted, according the journal, Science, which reported that “an alternative payment scheme … could allow those studies to continue”.

Over the past two decades, South Africa has become a “preferred site” for HIV and tuberculosis research, both because of its high burden of HIV and TB and the excellence of its scientific community, according to Professor Ntobeko Ntusi, head of the South African Medical Research Council (SAMRC).

It has been disproportionately affected by the NIH’s change in policy towards subawards, which jeopardised at least 27 HIV trials and 20 TB trials, according to an analysis by the Treatment Action Group (TAG) and Médecins Sans Frontières (MSF).

In 2024, the NIH funded about 3,600 foreign subawards worth more than $400 million, according to Science.

The NIH wants to control allocations to foreign research groups, stipulating that they will need to apply directly to NIH for grants, not go via third parties. However, it will only have the new award procedures in place by 30 September, leaving thousands of research projects in limbo.

Explaining its position in an announcement on 1 May, the NIH said that it wants to “maintain strong, productive, and secure foreign collaborations” and  “ensure it can transparently and reliably report on each dollar spent”.

As a result, NIH “is establishing a new award structure that will prohibit foreign subawards from being nested under the parent grant. This new award structure will include a prime with independent awards that are linked to the prime that will allow NIH to track the project’s funds individually,” according to the announcement.

However, it now appears to have made exceptions for clinical trials involving people in the interim. 

“Staff guidance dated 30 June maintains that grant renewal and new applications including a foreign subaward submitted after 1 May will not be reviewed until the new tracking system is in place,” according to Science.

“But the document describes an exception for human subject research in applications submitted earlier, and for ongoing human studies. As a temporary measure, NIH grants staff can convert the subawards within these projects to special ‘supplements’ to the main grant that will go directly to the foreign collaborator, the document says.”

NIH official Michelle Bulls informed grants staff in a memo on 27 June that, although no new awards can be made to South Africa, “existing subawards with clinical research can continue under the new ‘supplement’ plan… and ongoing prime awards to South African researchers, which make up about 100 of the country’s NIH grants, ‘may proceed’,” according to Science.

Prof Ian Sanne, co-principal investigator of the Wits HIV Research Group Clinical Trials Unit, earlier described navigating the US funding cuts as a “major regulatory and ethics nightmare”.

One of the studies Sanne oversaw that was terminated involved a trial of microbicide rings filled with slow-release antiretroviral medication to prevent HIV that were inserted vaginally in trial participants, many of whom were at high risk of HIV infection.

However, restarting the research is not a simple matter as, in the two-month pause in NIH payments, trial participants have dispersed and research staff have been retrenched.  In addition, there is no guarantee that current subawards will qualify for awards under the new system.

NIH targets journal fees

Meanwhile, the NIH announced this week that it was cracking down on “excessive publisher fees for publicly funded research”.

The NIH claimed that “some major publishers charge as much as $13,000 per article for immediate open access, while also collecting substantial subscription fees from government agencies. 

“For example, one publishing group reportedly receives more than $2 million annually in subscription fees from NIH, in addition to tens of millions more through exclusive article processing charges (APCs). These costs ultimately burden taxpayers who have already funded the underlying research.”

In 2026, the NIH will introduce a cap on “allowable publication costs” (APC) to ensure that  publication fees “remain reasonable across the research ecosystem”. 

“This policy marks a critical step in protecting the integrity of the scientific publishing system while ensuring that public investments in research deliver maximum public benefit,” said NIH director Dr Jay Bhattacharya.

A researcher collects information on pathogens during a disease outbreak. How such information is shared in a fair and equitable way is the next phase of the pandemic agreement talks.

The next – and tricky – phase of cementing the World Health Organization’s pandemic agreement resumes on Wednesday (9 July) with the first meeting of the Intergovernmental Working Group (IGWG).

The IGWG’s main task is to negotiate an annex to the pandemic agreement on a pathogen access and benefit sharing (PABS) system. This system will set out how information about pathogens with pandemic potential is shared in a safe, transparent and accountable manner, and how those who share information will benefit from products that are developed as a result.

It is a hot potato given tensions between intellectual property rights for pharmaceutical companies and wide access to affordable medical products.

In addition, the IGWG will prepare the ground for the Conference of the Parties that will govern the pandemic agreement, and the terms of reference for a coordinating financial mechanism, which will help defend countries against outbreaks and pandemics.

According to WHO legal officer Steven Solomon, the PABS annex has to be completed by 17 April 2026 to meet the deadline of submission to the World Health Assembly in May 2026.

This means that the IGWG has merely nine months and eight days to complete its work to meet the deadline.

This week’s meeting will be dedicated to electing the office-bearers, setting out timelines and modalities for engagement with relevant stakeholders.

The first item on the IGWG agenda is the election of two co-chairs and four vice-chairs – one for each of the six WHO regions. As with the Intergovernmental Negotiating Body (INB) that ran the pandemic agreement talks, the co-chairs are to reflect developing and developed countries.

IGWG co-chair contender, the UK’s Dr Mathew Harpur.
IGWG co-chair contender, Brazil’s Ambassador Tovar da Silva Nunes

Ambassador Tovar da Silva Nunes, Brazil’s Permanent Representative to the United Nations Office in Geneva, and Dr Mathew Harpur, Deputy Director for Multilateral and G7/G20 Engagement for the UK’s Department of Health and Social Care, are strong contenders for co-chairs, according to sources.

The INB co-chairs, France’s Ambassador Anne-Claire Amprou and South Africa’s Precious Matsoso, are passing the baton to new leaders, although the pandemic agreement that they oversaw contains the outline of the PABS system.

Addressing a recent meeting in Geneva, Amprou said that preparatory work for the implementation of the pandemic agreement should start as soon as possible, in parallel with negotiations on the annex.

Amprou added that she though that the annex should be a short document and that “this negotiation should be much more technical than political [as] we know the political positions of different member states”.

As with INB meetings, open sessions of the IGWG will be webcast and stake-holders in official relations with the WHO will be permitted to attend and contribute at certain times.

An anti-smoking campaign in China, the biggest consumer of tobacco products.

As the tobacco industry continues to innovate to preserve its market appeal, the health sector needs to become even more creative – advocating for new regulations to reduce tobacco’s appeal and increase product costs. Among those: limiting nicotine content, banning filter tips, and joining WHO’s new “3×35 initiative” to raise the price of tobacco products by 50%. 

We’re on the brink. For much of the last 20 years, smoking has been in decline worldwide, saving millions of lives, but we are at an inflection point. Trends point to a flattening in the decline of cigarette sales, and Big Tobacco is responding to two decades of public health progress with insidious innovation. If public health practitioners don’t out-innovate the industry now, we’ll be setting ourselves up to lose.

It is a monumental public health achievement that global tobacco use dropped by a third in the last 20 years. More than 5.5 billion people are now covered by some measure that discourages tobacco use, such as advertising bans, higher taxes and quit programs. For the first time, an entire region, Latin America, has smoke-free laws in place.

But we cannot expect the hard-won anti-tobacco laws of today – those that have created smoke-free spaces, banned advertisements around schools and removed flavors from cigarettes which have saved millions of lives – to protect us from the industry’s plans for tomorrow.

Despite its seemingly anti-cigarette rhetoric, the industry is not slowing down on its core product – monetizing addiction. There are too many signals to ignore: Philip Morris International shipped more cigarettes in the first quarter of 2025 than during the same period last year. British American Tobacco just launched a new cigarette brand in Korea. Japan Tobacco International is building a new factory in Morocco.

Industry is innovating around anti-smoking regulations 

Tobacco industry innovation includes a barrage of new tobacco products.

The industry is also innovating its way around current anti-smoking regulations, releasing a barrage of new products like e-cigarettes (vapes), heated tobacco products and nicotine pouches. When laws threaten to restrict or ban these addictive products, tobacco companies try to influence politicians to advocate for them, often as the “lesser evil”. 

These products are increasingly being targeted at the next generation. The industry has lobbied for heated tobacco products to be exempt from the UK’s new Tobacco and Vapes Bill so they can continue to be sold to people who would no longer be able to buy cigarettes. It also wants to continue promoting these products in a wide range of retail outlets, which has included items at children’s eye-level, near sweets in filling stations. 

Meanwhile, there are reports from across the UK of nicotine pouch giveaways at railway stations and tobacco companies sponsoring music events like the Reading and Leeds Festival, where many teens go to celebrate the end of exams.

If nothing is done to counter the industry’s strategies, not only will declines in smoking be reversed, but new epidemics will arise. Indeed, an e-cigarette epidemic already has, with vapes being used more by teens than adults in many countries. We’re risking a future where the next generation won’t have the same protections.

Out-innovating big tobacco 

But tobacco companies aren’t the only ones innovating. New ideas are emerging that can move the needle in the right direction, for good. 

We can require that cigarettes have less nicotine, so that fewer people get hooked for life. We can use technology to blur out tobacco company logos and branding in Formula 1 races, as in France, and address imagery on streaming platforms, like in India. 

We can institute “polluter pays” penalties where tobacco companies compensate for the environmental damage their products cause, like in Spain. We could ban filters to remove a product design element that makes it easier to smoke and eliminate the most littered single-use plastic in the world. We can prohibit the youngest generations from ever being allowed to buy tobacco.

These solutions can be agile and deployed at the national, provincial or city level. The generational end game law, which makes it illegal to sell tobacco to anyone born after a certain date, is being pioneered at the city level in Brookline, Massachusetts, in the United States. A similar law is set to go into effect in the UK soon.

To prevent a backslide into the era of smoke-filled rooms and Joe the Camel, these solutions need to be accelerated and supported in every country.

So there couldn’t have been a better time for the tobacco control community to gather than at the recent World Tobacco Conference in Dublin, Ireland. 

Experts and advocates from around the world convened in a country that itself is wrestling with stalled declines in tobacco use and a rise in youth e-cigarette use. While Ireland aimed to reduce tobacco use to less than 5% by 2025, recent data shows it hovering at 17%. Worryingly, a 2022 survey revealed that two in every five girls and a quarter of boys aged 15-17 had used an e-cigarette.

Convening in Dublin provided an opportunity to double down and renew the push for what we know works: advertising bans, smoke-free laws and – the gold standard – higher tobacco taxes. 

Raising real prices

Following that major meeting, the World Health Organization (WHO) has now launched a big new initiative urging countries to raise real prices on tobacco, alcohol, and sugary drinks by at least 50% by 2035 through health taxes. The “3 by 35” Initiative is based on studies showing that a one-time 50% price increase in these products could prevent 50 million premature deaths over the next 50 years. 

This period between Dublin and the upcoming UN High Level Meeting on Noncommunicable Diseases in September is a time to mobilize action behind these creative new solutions that can counter Big Tobacco well into the future.

The tobacco industry is playing the long game, and we need to, too. No public health win is permanent. If politicians and the public aren’t vigilant, Big Tobacco will continue trying to dismantle laws that protect health, while finding ways to bypass others. The next era of tobacco control requires innovative solutions – they will make all the difference. 

Dr Mary-Ann Etiebet is the President and CEO of Vital Strategies where she leads a team of over 400 people in over 80 countries working to advance long-term solutions for the growing burden of noncommunicable disease and injury.

Delhi traffic officer Ashok Kumar explains the new rules on 1 July.

NEW DELHI – When drivers entered fuel stations on 1 July, they found bright new warning signs and traffic police positioned at the fuel pumps. Old vehicles would be identified by special, new cameras and denied fuel. Drivers  also risked having their vehicles seized for “liquidation.” 

The day marked the beginning of a widespread campaign by central government’s Commission for Air Quality Management (CAQM) in the Delhi region to reduce air pollution.  

Any gasoline-powered vehicle older than 10 years, or a diesel vehicle older than 15 years, was supposed to face action – and at least 80 such vehicles were seized initially.

Although some  6.1 million over-age vehicles are registered, the actual number on the roads is far lower, and some estimate it to be around 400,000. 

However, enforcement quickly fizzled out after the Delhi state government sought a pause following protests on social media. Many of these went viral and were also reported widely in the media. 

Enforcement aided by advanced new cameras

To identify these vehicles at the pumps and on the road, CAQM installed hundreds of advanced cameras with automated number plate recognition (ANPR) linked to a database. 

The ban on such older vehicles circulating in Delhi was first introduced in 2015, but after two days of protests over the enforcement, the Delhi government pressured CAQM to put the operation on hold. 

Chief Minister of Delhi Rekha Gupta tweeted that the decision should be suspended as it was adversely affecting the daily lives and livelihoods of millions of families. She called for a practical, equitable, and phased solution.

Delhi’s environment minister, Manjinder Singh Sirsa, cited several “technological gaps” in the ANPR system in a letter to CAQM posted on X on Thursday. These include that it lacks robustness, there are crucial glitches in the camera placement, sensors aren’t working, and the system is not fully integrated with databases of states neighbouring Delhi. He called for a “holistic approach and implementation” in Delhi and its neighbouring regions. 

However, a source told Health Policy Watch that ANPR was able to identify up to 6,000 overage vehicles per day during tests, and described it as a “foolproof” method. Tests conducted since last December showed that the system has worked well. 

Ironically, a day before the enforcement drive began, Gupta of Prime Minister Narendra Modi’s BJP Party said that the Delhi state government would follow orders of the courts and the CAQM.

Despite repeated inquiries from Health Policy Watch, CAQM did not provide any details on the future of the campaign in Delhi. However, it made it clear in a press release related to curbing pollution in neighbouring Haryana state, that it intends to continue to advocate for the liquidation of the ‘end-of-life’ (EoL) vehicles plan and ANPR cameras. 

The initial campaign in Delhi was supposed to be part of a regional initiative by Indian authorities that aimed to get an additional 4.5 million EoL vehicles off the road starting in two phases in November,  then April 2026. The rollout of ANPR cameras in other states and cities had also begun. 

However, as long as the Delhi State Government opposes enforcement, the agency will find it difficult to continue to clean up Delhi.  

Weak political appetite to tackle air pollution

The call for a pause signals the weak political appetite of the five-month-old Delhi government to take hard decisions to improve air quality in what has frequently been ranked as the world’s most polluted capital over the past decade. 

Even before Sirsa’s letter to CAQM last week, there was a perceptible shift in the party’s tone. In March, Sirsa promised an early crackdown on polluting vehicles that are a major contributor to Delhi’s annual air pollution, particularly in winter:

Older vehicles emit high levels of polluting nitrogen oxide (NOx), sulphur dioxide (SO2) and contribute to the microscopic pollutant, PM2.5. In 2024, PM2.5 levels reached peaks of 732 micrograms per m3 – about 73 times higher than the World Health Organization’s (WHO) 24-hour guideline level. 

But on 2 July after the protests, Sirsa blamed the previous Aam Admi Party (AAP) government for not enforcing the ban earlier:

The protests included many influential voices across the political spectrum. But most ignore health impacts and the fact that the older cars have outdated fuel standards, which means that they are inevitably more polluting, regardless of how well they may have been maintained. 

Health impact of vehicular pollution 

Drivers and passengers in heavy traffic with many polluting vehicles are typically exposed to excessively high levels of oxides of Nitrogen (NOx) from gasoline vehicles, as well as fine particulates, PM2.5 from diesel. 

Even short-term exposure to high levels of those pollutants prompts immediate, physiological responses, including headaches, irritation in the eyes, nose and throat, and difficulties in breathing. 

Chronic, long-term exposure to traffic pollution can have far more severe health effects, worsening asthma and other lung disorders, cardiovascular problems and high blood pressure, leading to premature death. 

Air pollution has also been identified in a new report as being a more significant cause of lung cancer in ‘never smokers’ than previously believed, according to a new study published in Nature. Patients from regions of the world with high levels of air pollution were more likely to have genomic mutations linked to cancer.

In Delhi alone, 7.8 years life years are estimated to be lost from air pollution while the average for India is 3.6 years. 

WHO’s South East Asia region, which extends east from Pakistan to Bangladesh, continues to have the highest overall burden of disease from air pollution, and India is one of the worst-affected countries. A little over two million Indians a year die from air pollution, with the worst effects concentrated in Delhi and other major cities. 

Air pollution is also linked to obesity, diabetes, metabolic dysfunction and genomic damage, points out Dr Sanjeev Bagai, a prominent paediatrician in Delhi. 

“Vehicular pollution is the lesser-mentioned culprit causing serious human harm,” he said in an interview with Health Policy Watch.

Vehicles are a big chunk of Delhi’s air pollution

In the Delhi region, vehicles contribute significantly to the air pollution crisis. According to officials, vehicles emit 78% of the nitrogen oxide (NOx), 41% of sulphur dioxide (SO2), and at least 28% of PM 2.5 particulate matter pollution –  although some estimates put it at 40% and as much as 50% in winter. Much of the NOx also converts to PM 2.5, which is so fine that it can settle deep into the lungs and other organs, causing damage. 

Neither the science nor the policy to get older vehicles off the road are new.  A ban on EoL vehicles has been in force since 2015, when it was first ordered by the nation’s top environmental court, the National Green Tribunal (NGT). The ban was upheld in 2018 by the Supreme Court and in 2024, a powerful panel headed by the country’s top bureaucrat, then Cabinet Secretary Rajiv Gauba, called out the “very slow progress” on implementing the ban. 

Science vs #DelhiFuelBan protests

Many of those criticising the crackdown claim that 10 or 15-year-old vehicles can remain in good condition. For instance, one social media user praised his father’s 16-year-old Mercedes as a so-called “zero pollution” vehicle.

The facts, however, don’t bear that out. Vehicles with the latest fuel standard –  Bharat Stage 6 (BS 6), equivalent to Euro 6 – emit far less pollution than earlier standards, according to a study by the International Council on Clean Transportation (ICCT). 

In its 2024 report, the ICCT said that so far, India’s “leap” from BS 4 to BS  was contributing to “significant reductions in tailpipe emissions.” Even 5- to 10-year-old vehicles with a BS 4 standard are approximately five or six times more polluting, while those that are 10 years or older, with BS 3 and BS 2 standards, can be 10 and 11 times more polluting, ICCT said.

But the claim that well maintained older vehicles are “clean” are being widely promoted, including by this influencer with over 15 million YouTube followers:

Protests across political spectrum

Criticism of the ban has come across most of the political spectrum. An opposition Member of Parliament, Saket Gokhale of the Trinamool Congress, called the ban “ridiculous” and a “major financial hit to the middle class”, affecting six million owners. He has written to the federal transport minister asking for the policy to be withdrawn:

A columnist appealed to Prime Minister Modi, who follows her on X, to allow old vehicles that comply with emission norms. She cites an automobile manufacturers group, which claims that a large number of these vehicles can meet stringent standards. 

Most air quality advocates are silent

On the other hand, the usually vocal air quality advocates were largely silent. The authorities also did not defend the ban once the protests began increasing. 

Approaches by Health Policy Watch to several organisations yielded no response. Amongst the few exceptions were Karthik Ganesan and Arpan Patra of the Council on Energy, Environment and Water (CEEW). 

In an article on Thursday in the Indian Express, they welcomed the measures as being a good, first step shortly before the campaign was suspended. 

“The restriction on the fuelling of end-of-life vehicles in Delhi firmly communicates the government’s intent to curtail pollution… This ban must cascade into the following logical next steps to truly clean up transportation emissions,” wrote Ganesan and Patra.

Until now, the government had largely relied on frequent, mandatory pollution checks on vehicles that pulled into service stations, but these use old technologies that only check for very high levels of smoke particles and carbon monoxide. They don’t capture data on fine particulate matter, nitrogen oxides and sulphates, which are the pollutants most harmful to human health. 

As for more sophisticated testing, there are only two vehicle fitness centres in the entire city of more than 22 million people capable of this.

Meanwhile, studies by the ICCT and others have demonstrated that filtering vehicles by their age rather than rudimentary and outdated emissions tests, is a more reliable means of getting polluting vehicles off the road. 

Cameras installed at Delhi service stations can identify older vehicles by their registration plates. But their use now hangs in the balance after the government suspended implementation of the ban on older vehicles.

Will the new Delhi government ever step up? 

Experts say that enforcing the ban is just one step in reducing Delhi’s air pollution at its source. Public transport is patchy and buses don’t reach many neighbourhoods. 

About 31% of urban neighbourhoods in Delhi fall outside a 500-meter radius of a public bus stop, a threshold recognised as the standard for walkable access under India’s Transit-Oriented Development (TOD) policy, according to a recent study.

If the government does eventually enforce the ban on old vehicles using its updated technology, it will also be expected to enforce other court orders and pollution curbs  like the ban on fire crackers and steps against waste burning. 

If it doesn’t, it will need to contend with the optics. As Ashwini Tewari, the chief of India’s largest bank, State Bank of India, pointed out recently, foreigners want to avoid the Delhi region, including the booming city of Gurgaon on its southern border, where major multinationals like Google, Microsoft, IBM and Deloitte have large offices. 

The quality of the Delhi government’s air pollution mitigation strategies thus has major economic implications at the national as well as local level. 

The record for this new BJP government, which came into power in February, remains very mixed. While it is continuing and extending policies such as more EV buses, it is also is facing criticism for a plan to install so-called ‘modern air purifiers’ in the park of an elite neighbourhood despite a failed earlier experiment with outdoor smog towers. 

The new plan is to install 150 such ‘air purifiers’ over 85 acres. But with Delhi is spread over 366,000 acres, any such initiative will be ineffective, as experience and studies have shown. 

Cutting pollution at source is always a better option, as air quality researchers point out. For now, a series of pollution maps of Paris, showing how a curb on vehicles improved air quality, has gone viral in India.

North Darfur capital of El-Fasher from above.

Mass atrocities, rape, famine, sexual and ethnically targeted violence have plagued Sudan’s civil war since it erupted two years ago. With peace nowhere in sight, a new report released by Médecins Sans Frontières (MSF) recounts in devastating detail: nothing has changed. 

Based on interviews with over 80 civilians, MSF data and direct observations from its medical teams, the report documents the violence and humanitarian catastrophe unfolding in El Fasher, the capital of North Darfur, where the Rapid Support Forces (RSF) have encircled hundreds of thousands of people while laying the city under siege.

Mass killings and starvation are underway, MSF found. Food, water, and humanitarian aid are blockaded. Food shops and markets, water towers and pumps, hospitals and healthcare facilities are under constant attack.

The Sudan Doctors Network reports 239 children have died from malnutrition in El Fasher since January as nearly half of Sudan’s remaining population facing acute food insecurity turn to boiling weeds and wild plants to survive.

Gunfire, airstrikes and artillery are already raining down on the city as the warring factions compete for control. But MSF warned further escalation is still possible: an all-out RSF assault on the capital.

“In light of the ethnically motivated mass atrocities committed on the Masalit in West Darfur back in June 2023, and of the massacres perpetrated in Zamzam camp in North Darfur, we fear such a scenario will be repeated in El Fasher,” said Mathilde Simon, MSF’s humanitarian affairs advisor. “This onslaught of violence must stop.”

Ethnically targeted attacks by the RSF on non-Arab communities, particularly the Zaghawa, are “protracting the ethnic violence that has ravaged Darfur for over twenty years,” MSF said.

“RSF and their affiliates repeatedly shelled neighbourhoods and gathering places of civilians known to be from non-Arab communities, ground attacks were systematically carried out, involving the looting of belongings, killing of civilians and razing of houses and infrastructure,” the report found. “Sexual violence was widely perpetrated, and numerous abductions were reported.”

The RSF is a descendant of the Janjaweed militia that led the Darfur genocide, targeting non-Arabs across the region and killing an estimated 300,000 people from 2003 to 2005. 

Mohamed Hamdan Dagalo, the general known as Hemedti who heads the RSF, led Janjaweed paramilitaries that burned villages, killed civilians and raped ethnic Africans across his native Darfur during the genocide. These crimes led to the indictment of his then-commander and deposed Sudanese president, Omar al-Bashir, by the International Criminal Court for war crimes and genocide.

With the shadow of a repeat of history looming over the province, MSF reported several witnesses testified they overheard RSF soldiers airing plans to “clean El Fasher,” raising the spectre of a second genocide – or that it is already underway.

“Only God knows what will happen in El Fasher,” one man, 41, told doctors. “But if the RSF take El Fasher, they will carry out ethnic cleansing and genocide, like what happened in El Geneina.”

El Geneina, the capital of West Darfur, was systematically cleared of its Massalit population by RSF and allied militias through killing and forced displacement in 2023. The total number dead in the violence is unknown. A UN expert panel estimated between 10,000 and 15,000 people were killed, while Sudanese Red Crescent staff identified 2,000 bodies on the capital’s streets before they stopped counting.

As MSF urges the warring parties to spare civilians and grant access for humanitarian organisations to provide critical aid to people in need, RSF forces took control of the tri-border area with Libya and Egypt in June, gaining control over critical supply routes and threatening to open new fronts in the civil war. 

“As patients and communities tell their stories to our teams and asked us to speak out, while their suffering is hardly on the international agenda, we felt compelled to document these patterns of relentless violence that have been crushing countless lives in general indifference and inaction over the past year,” Simon said.

Despite a UN arms embargo, weapons continue flowing to both sides through neighbouring countries, several of which, including Libya, Chad and the Central African Republic, are major arms trafficking hubs, UN experts say. 

While Egypt and Saudi Arabia back government forces, the UAE, Libya and Russian-linked Wagner Group support the RSF. The UAE has invested over $6 billion in Sudan since 2018, viewing the resource-rich nation as key to expanding its regional influence.

Around 40,000 people have been killed and 13 million displaced since the civil war began in April 2023, according to the latest UN estimates.

Peace, at this juncture, is nowhere in sight.

Nowhere to hide

Over 400,000 people were forced to flee to El Fasher from the Zamzam refugee camp, the largest displacement encampment in Sudan just south of the city, after an RSF ground assault in April that killed more than 500 civilians.

Those who made it to the city “remained trapped, out of reach of humanitarian aid and exposed to attacks and further mass violence,” MSF said – and there is no way out.

“Survivors who managed to flee have undergone further violence along the road, with men being specifically targeted, women and girls being raped and civilian convoys attacked,” the report found. 

“The harrowing level of violence on the roads out of El Fasher and Zamzam means that many people are trapped or take life-threatening risks when fleeing. Men and boys are at high risk of killing and abduction, while women and girls are subjected to widespread sexual violence.”

The millions who successfully flee Sudan find crisis there too.The World Food Programme warned Wednesday that life-saving assistance may soon shut down in the Central African Republic, Chad, Egypt, Ethiopia, Libya, South Sudan and Uganda – all grappling with their own domestic food insecurity needs – as funding cuts and new arrivals overwhelm support systems.

“This is a full-blown regional crisis that’s playing out in countries that already have extreme levels of food insecurity and high levels of conflict,” said Shaun Hughes, WFP’s Emergency Coordinator for the Sudan Regional Crisis. “Refugees from Sudan are fleeing for their lives and yet are being met with more hunger, despair, and limited resources on the other side of the border.”

Rape as a weapon of war

Violence and attacks on healthcare forced MSF to shut down operations in El Fasher and Zamzam camp.

Sexual violence has been a central feature of the violence in Sudan throughout the war. While both the Sudanese Armed Forces and the RSF have been found to commit sexual war crimes, the overwhelming majority are attributed to the RSF and its allies.

The UN Independent fact-finding mission on Sudan and Amnesty International separately found the militia had engaged in widespread sexual and gender-based violence, rape, sexual slavery, and abduction, among other crimes against humanity. RSF forces are further accused of using mass rape as a weapon of war and to assist ethnic cleansing efforts, using rape as a tool to drive fear and force women to flee.

“I have a certificate for first aid nursing. [When they stopped us], the RSF asked me to give them my bag. When they saw the certificate inside, they told me, ‘You want to heal the Sudanese army, you want to cure the enemy!,'” one woman, 27, told MSF. “Then they burnt my certificate and they took me away to rape me.”

No comprehensive statistics on sexual violence in Sudan exist. The latest number on confirmed cases, compiled by the advocacy group Together Against Rape and Sexual Violence and published on 4 June, documented 377 cases of rape since the war began.

Data on rape and sexual assault in war zones are notoriously inexact. In Sudan, survivors face an array of barriers from social stigma, to lack of adequate medical support, and a dysfunctional judicial system with no means to protect or prosecute if they speak out. The Sudanese government’s Unit for Combating Violence Against Women previously warned verified rape cases may represent as little as 2% of the total.

Since the start of the war, the number of people at risk of gender-based violence has more than tripled to 12.1 million people – 25% of the country’s population. The number of gender-based violence survivors seeking services increased 288% in 2024, according to UN Women.

The most harrowing finding came from Unicef in May: 221 rape cases against children were recorded by since the beginning of 2024. The youngest reported survivors were four one-year-olds. Sixteen child rape survivors, including the infants, were under 5 years of age. 

“Children as young as one being raped by armed men should shock anyone to their core and compel immediate action,” said Unicef executive director Catherine Russell.

Unicef found an additional 77 instances of sexual assaults against children, mostly attempted rape cases. Two-thirds of recorded cases were girls, but 33% were boys, which the agency noted requires “specific attention as they may face stigma and unique challenges in reporting, seeking help, and accessing services.”

“Millions of children in Sudan are at risk of rape and other forms of sexual violence, which is being used as a tactic of war. This is an abhorrent violation of international law and could constitute a war crime. It must stop.”

Southern spiral

The violence consuming Sudan threatens to spill across its southern border, where South Sudan, the world’s youngest nation, stands on the brink of a new civil war of its own.

South Sudan won independence from Sudan in 2011, ending the longest civil war in the history of the African continent. Twenty-two years of violence, disease and famine killed 2 million people, the highest civilian death toll since World War II.

Independence was quickly followed by civil war. In 2013, a break-down of the power-sharing agreement negotiated two years earlier resulted in five years of war, killing 400,000 and displacing 4 million before a new power-sharing agreement brokered in 2018 brought fragile peace to the fledgling state.

That agreement collapsed once again in March when President Salva Kiir’s forces arrested his former deputy Riek Machar, mirroring Sudan’s trajectory when two rival generals, charged with overseeing the country’s transition to democracy, instead dragged the country and its 50 million people into all-out war.

Since March, violence against civilians in South Sudan has since reached its highest level since 2020, the UN reported Wednesday, with 1,607 attacks in the first quarter of this year. Those include 739 civilians killed, 679 injured, 149 abducted, and 40 subjected to conflict-related sexual violence between January and March.

The escalating violence is already pushing South Sudanese civilians towards famine. Over 22,000 people are likely already starving, while nearly 60% of the population faces life-threatening food insecurity as a result of the escalating violence, the IPC warned in June.

Armed groups move freely across the porous border drawn only in 2011, with overlapping ethnic militias and historic alliances threatening to erase the fragile line between two conflicts – trapping 61 million people, once again, in a renewed cycle of violence.

“Given this grim situation, we are left with no other conclusion, but to assess that South Sudan is teetering on the edge of a relapse into civil war,” Nicolas Haysom, the UN’s top official in South Sudan, warned when the peace deal collapsed. “It would devastate not only South Sudan but the entire region, which simply cannot afford another war.”

The world faces a global health funding crisis, but John-Arne Røttingen believes the solution goes beyond money. It lies in stronger partnerships between governments, researchers, and citizens.

“Science is not enough to change the world,” said Røttingen, the newly appointed CEO of Wellcome, one of the world’s largest global health foundations. “It must be allied with collaboration and action across society.”

In a wide-ranging conversation on Trailblazers with Garry Aslanyan, Røttingen spoke about his leadership values, his vision for Wellcome, and the pressing need to rethink how global health is funded and delivered. A former head of CEPI and Norway’s global health ambassador, Røttingen said foundations like Wellcome must act as catalysts—not substitutes—for government and private-sector leadership.

“We need to engage governments more directly,” he said. “Ultimately, it is governments that are responsible for the health of their populations.”

Røttingen emphasized the importance of equity in science, calling for more research led by local experts in the Global South. He described visits to research centres in Malawi, Kenya, and Vietnam, where Wellcome supports programs that combine population health with advanced laboratory science.

But trust is also key.

“We need to double down on trust in science,” he said, citing public skepticism during the COVID-19 pandemic. That includes involving communities more directly in setting research priorities.

“We have to tackle problems that are important to people,” Røttingen added.

Røttingen urged the global health community to act fast as external funding shrinks and global crises multiply.

“We have some good indications of where we should go. We just need to act on them—and bring them to life,” he said.

Artificial intelligence can transform global health—but only if developed and deployed with equity in mind.

That was the message from two global health experts featured on the latest Global Health Matters podcast episode, “AI for Equity: Bridging Global Health Gaps.”

“In the future, a physician working in a remote area will have the best cardiologist in the world, the best pneumologist in the world, right next to them—ready to answer any questions,” said Alexandre Chiavegatto Filho, professor of machine learning in health at the University of São Paulo.

His team is developing mobile apps that allow frontline doctors to access AI tools through smartphones, even in areas without electronic medical records.

Jiho Cha, a South Korean parliamentarian and physician, has a similar vision. He believes AI can scale up health services in fragile settings, where doctors are scarce and health systems are overwhelmed.

“AI-powered information systems combined with fintech or blockchain technologies can improve health financing and delivery,” Cha said.

He described how AI can support nurses and community health workers by enhancing diagnostic and decision-making abilities.

However, both experts warned that the same technology could widen gaps if not handled carefully.

“If you leave AI by itself, it’s probably going to increase inequality,” Filho cautioned, noting that algorithms trained on wealthier populations tend to perform worse for low-income groups.

They said the challenge is to ensure AI is trained on diverse, locally relevant data and made accessible in low-resource settings. Otherwise, the digital divide will deepen.

“We have a huge opportunity in our hands,” Filho said. “But we need to make sure AI works where it’s needed most.”
