Asia-Pacific parliamentarians urge bolder action for universal health coverage, climate resilience and responsible AI
Parliamentarians representing 16 countries from across the Asia-Pacific region concluded the Ninth Meeting of the Asia-Pacific Parliamentarian Forum on Global Health (APPFGH) today, reaffirming their key role in advancing universal health coverage (UHC) amid the risks and opportunities posed by AI and climate change. In adopting the Phnom Penh Communiqué, parliamentarians urged fellow legislators regionwide to strengthen sustainable financing for UHC to widen access to health for all, including the most vulnerable populations; promote responsible governance of AI amid ethical concerns over this fast-evolving technology; and build climate-resilient health systems to anticipate and respond to mounting pressures ranging from rising sea levels in coastal areas to air pollution and other environmental degradation.The National Assembly of Cambodia, with support from Cambodia’s Ministry of Health and the World Health Organization (WHO), hosted the Forum in Phnom Penh from 11 to 13 August 2026 – the first time the Forum has convened in a Mekong country.Parliamentarians urge action to close gaps in accessIn the Communiqué, parliamentarians recognized that at-risk and marginalized groups are the ones most severely affected by gaps in access to health services. These groups include people living in poverty, women and children, persons with disabilities, older people, migrants, refugees, and those in rural, remote or island communities. The Communiqué urges fellow parliamentarians and policy-makers to advocate for laws and policies that support sustainable financing to protect people from financial hardship, with a focus on primary health care, prevention and equity. "The Communiqué is a call to action. It sets out ambitious, concrete measures that deliver meaningful impact on the ground. We are all accountable for advancing universal health coverage and translating our commitments into tangible results. Cambodia is fully committed to advancing UHC, including the promotion of ‘healthy people, prosperous country’ campaign,” said Samdech Maha Rathsapheathika Thipadei Khuon Sudary, President of the National Assembly of the Kingdom of Cambodia.His Excellency Professor Chheang Ra, Minister of Health of the Kingdom of Cambodia, highlighted the need for collaboration beyond the health sector. “Universal health coverage cannot be achieved by the Ministry of Health alone. It requires support, particularly from parliamentarians, across political, legislative, financial, social protection, education, infrastructure, and environmental domains. While each country follows its own path, one factor is universally critical for success: strong governance and leadership. We all believe in this principle, and in our respective political roles, we remain committed to strengthening these key success factors to ensure that no one is left behind.”Promoting responsible AI adoption Parliamentarians acknowledged that, while AI has already demonstrated its ability to improve access to health services and support delivery, careful and ethical governance is necessary to safeguard quality, safety, privacy and public trust. This underscores the importance of parliamentarians in promoting legal and regulatory frameworks addressing liability, records ownership and data governance, while embracing innovation that protects ethical practice.“Without strong governance, safeguards for privacy and data security, sustainable financing, and attention to those most at risk of exclusion, new technologies may widen existing gaps instead of closing them. This is why parliamentarians matter. We pass laws. We approve budgets. We scrutinize government action. We represent communities. We can ask whether health services are reaching rural, remote, ageing, poor, and marginalized populations. We can ask whether innovation is being guided by equity, evidence, and ethics,” said Hon. Man Hee Lee, President of the Asia-Pacific Parliamentarian Forum on Global Health.Building climate-resilient health systemsParliamentarians also reiterated that the climate crisis is a direct threat to people’s health and to achieving UHC more broadly, deepening the same gaps in access already faced by at-risk and marginalized communities. They recognized the need for WHO Member States to ensure sufficient national appropriations and oversight, and for parliamentarians to raise awareness in their constituencies and mobilize local action in building climate-resilient and sustainable health systems.“Universal health coverage, climate change and AI cannot be addressed in isolation. The same communities struggling to access health services today are often the ones most exposed to climate shocks, and most in need of the opportunities AI can offer if this technology is governed responsibly,” said Dr Saia Ma’u Piukala, WHO Regional Director for the Western Pacific. “Having served previously in this Forum myself as a parliamentarian from Tonga, I recognize how the Phnom Penh Communiqué reflects the shared resolve of legislators across the Asia-Pacific region: the laws parliamentarians pass and the budgets they approve help ensure this progress reaches the people who need it most.”As the Forum drew to a close, delegates reflected on what they would carry back to their own parliaments and constituencies.“I wish to share three points here worth carrying home from Phnom Penh: we need to invest in primary health care as the foundation of coverage; we need to remove the barriers that keep people from care, whether financial, geographic or social; and we need to build systems that are inclusive by design, protecting those most at risk of being left behind,” added Hon. Ouch Borith, First Vice-President of the Senate of the Kingdom of Cambodia.###Notes for editors:The Asia-Pacific Parliamentarian Forum on Global Health (APPFGH) is a platform for parliamentarians to exchange ideas, build political will, strengthen capacity and foster collaboration towards sustainable health action. This was the ninth meeting of the APPFGH, with the theme “Universal Health Coverage in the era of Climate Change and Artificial Intelligence”. Target 3.8 of the Sustainable Development Goals calls on countries to achieve universal health coverage, including financial risk protection, access to quality essential health services, and access to safe, effective, quality and affordable essential medicines and vaccines for all. In the Western Pacific, UHC service coverage index (SDG 3.8.1) rose from 63 in 2000 to 81 in 2023 (figures include Indonesia), and roughly one in four people in the Western Pacific have experienced financial hardship (SDG 3.8.2). Progress towards UHC in the Asia-Pacific region remains uneven, with hundreds of millions of people still lacking access to essential health services or facing financial hardship due to health-related expenses. Strengthening the role of parliaments – through legislation, financing and oversight – is central to closing this gap and accelerating progress towards UHC across the region.Parliamentarians participating in APPFGH in Cambodia this week include: Hon. Pehin Dato Adanan YUSOF, Brunei Darussalam; Hon. Rosmawatty ABDUL MUMIN, Brunei Darussalam; Hon. LORK Kheng, Kingdom of Cambodia; Hon. YOS Phanita, Kingdom of Cambodia; Hon.

Burning through Türkiye's GDP: The high cost of fossil fuel PM2.5 pollution on public health – Centre for Research on Energy and Clean Air
Türkiye’s reliance on fossil fuels is generating massive air pollution health costs both within the country and throughout the region. This report finds that fossil fuels account for more than half (52%) of Türkiye’s population exposure to PM2.5 air pollution. The cumulative health impacts are estimated to cost the Turkish economy approximately USD 55 billion each year, equivalent to 4.1% of national GDP in 2024. The pollution is also responsible for roughly 26,500 deaths per year in the country, including deaths from cardiovascular and respiratory diseases, lung cancer, stroke, and diabetes.The impacts begin at the very start of life, with fossil-fuel-derived PM2.5 pollution contributing to an estimated 8,000 preterm births, 8,200 low-birthweight infants, 5,100 new cases of childhood asthma, and 6,500 emergency-room visits for asthma each year in Türkiye.Beyond the estimated deaths each year in Türkiye, air pollution from the country’s fossil fuel emissions also contributes to deaths and economic losses in neighbouring countries. In 2024, these emissions were estimated to cause: 32,000 deaths and USD 2.1 billion in economic burden in Egypt; 1,700 deaths and USD 0.2 billion in economic burden in Syria; 800 deaths and USD 0.8 billion in economic burden in Iraq; 500 deaths and USD 4.5 billion in economic burden in Israel; and 400 deaths and USD 1.5 billion in economic burden in Greece.Türkiye currently has no national ambient air-quality standard for PM2.5, despite the substantial health burden associated with exposure to the pollutant. Figure — The percentage of annual PM2.5 emissions in Türkiye’s fossil fuel emissions, using the EMEP emission inventory and EMEP MSC-W chemical transport model Key findings Türkiye’s fossil fuel emissions (from domestic sources as well as international aviation and shipping) account for 52% of population exposure to PM₂.₅ nationwide. PM2.5 pollution attributable to Türkiye’s fossil fuel use is responsible for approximately 26,500 deaths in the country every year, including deaths from cardiovascular and respiratory diseases, lung cancer, stroke, and diabetes. Children are among the most affected, with fossil fuel-derived PM2.5 pollution contributing to an estimated 8,000 preterm births, 8,200 low-birth-weight infants, 5,100 new cases of childhood asthma and 6,500 emergency room visits for asthma each year. The cumulative health impacts of fossil fuel-derived PM2.5 pollution are estimated to cost the Turkish economy approximately USD 55 billion each year, equivalent to 4.1% of national GDP in 2024. Transboundary pollution attributable to Türkiye’s land-based fossil fuel emissions also leads to thousands of deaths in five neighbouring countries, with estimated economic burden per year (as of 2024) reaching USD 2.1 billion in Egypt (3,200 deaths), USD 0.2 billion in Syria (1,700 deaths), USD 0.8 billion in Iraq (800 deaths), USD 4.5 billion in Israel (500 deaths), and USD 1.5 billion in Greece (400 deaths). Türkiye currently has no national ambient air quality standard for PM2.5, despite the substantial health burden associated with exposure to the pollutant. Reducing fossil fuel use and emissions across Türkiye’s energy, transport and industrial systems would deliver substantial air quality and public health benefits by reducing exposure to PM2.5 and preventing associated illness and deaths.

Integrated pollution and carbon mitigation delivers major health and economic cobenefits in China
Synergistic mitigation of air pollutants and greenhouse gases is crucial for achieving clean air and carbon neutrality, but quantitative evidence of sectoral and regional health co-benefits in China remains limited. Authors develop an integrated Energy-Economy-Air Quality-Health framework coupling CEEPA, GAINS, and a province-level health module to simulate fourteen policy scenarios from 2020 to 2050. Coordinated strategies reduce CO2 and pollutants (SO2, NOX, PM2.5) by 75% relative to 2020, avoiding more than 500,000 premature deaths by 2050 and yielding monetized gains of 1.07 trillion CNY. Health benefits concentrate in industrially dense and populous provinces, with near-term PM2.5 reductions driven by pollution control and long-term improvements reliant on decarbonization. The integrated approach achieves a benefit-to-cost ratio of 1.42, lowering abatement costs by 11% relative to pollution-only measures. These findings highlight the value of coordinated, sector- and region-specific strategies for simultaneous climate mitigation, air quality improvement, and public health protection.

Reimagining how scientists study the chemistry of the air
Professor Victoria Barber and doctoral student Cooper Crabtree are spearheading Keck Foundation-funded project charting a path toward better understanding atmospheric oxidation. by Álvaro Castillo, UCLA College of Letters and Science From the vantage point of Victoria Barber, a UCLA assistant professor of chemistry and biochemistry, understanding the chemical reactions that shape air quality and climate are among the most pressing scientific challenges of our time. And thanks to a recent grant from the W.M. Keck Foundation, she and doctoral student Cooper Crabtree will spearhead a new research project exploring exactly how pollutants form in the atmosphere. Specifically, the project will examine how volatile organic compounds transform through atmospheric oxidation and explore how pollutants, like smog, form in the atmosphere. VOCs are released by sources ranging from trees and wildfires to vehicle exhaust pipes and consumer products such as cologne and perfume. As they undergo atmospheric oxidation, they can transform into a wide range of other compounds. Anyone in Southern California can attest to the urgency of this area of research — for example, in late July of this year, Los Angeles County was under an active ozone pollution advisory for almost a full week. While many people associate ozone with the protective ozone layer high in the stratosphere, ground-level or tropospheric ozone is a harmful secondary pollutant formed through atmospheric oxidation. Understanding how VOCs transform into pollutants like ozone is therefore critical to improving air-quality forecasts and informing strategies to reduce exposure. “My group is focused on trying accelerate our understanding of these networks of reactions so that we can do a better job of predicting how those pollutants form,” Barber said. “When we make decisions about how we might alter emissions, we can understand how that’s going to influence the production of these downstream pollutants.” With support from the W. M. Keck Foundation, Barber and Crabtree are developing new experimental approaches that will combine — and improve — techniques to study hundreds of chemical systems more efficiently than traditional methods allow. Instead of spending years decoding a single VOC, the project seeks to dramatically expand the pace and scale of discovery. The grant comes at a particularly important moment for environmental research. Barber, who joined UCLA in 2023, says funding for climate and air-quality research, especially for early career scientists, has become increasingly difficult to secure, a challenge compounded for ambitious projects that require building entirely new research infrastructure. The Keck Foundation’s support, Barber said, provides the flexibility to pursue bold early-stage, high-risk ideas that may be more difficult to fund using conventional federal funding sources. “It’s really, really hard to do environmental research under the current federal paradigm,” Barber said. “By stepping in and providing stable and flexible funding to explore this new idea, the Keck Foundation is making a huge difference to my research program.” In addition to funding early-career faculty, the Keck Foundation’s support is also focused on empowering graduate students like Crabtree in their scientific growth. The project gives Crabtree the opportunity to help develop an entirely new experimental approach to studying atmospheric chemistry — an experience that will provide him with valuable technical skills, scientific training and preparation for the next stage of his career. Stable funding also allows doctoral students like Crabtree to devote themselves more fully to research rather than balancing their scientific work with additional teaching responsibilities needed to cover funding gaps. “Getting to devote more of my time to research this past school year has greatly improved the pace and quality of our experiments, data analysis and planning for our future work,” said Crabtree, who is pursuing a Ph.D. in chemistry. “I feel very lucky — especially amid the current uncertainty surrounding scientific funding — to be able to continue exploring exciting knowledge gaps in our field and growing as a scientific researcher.” For Barber, mentorship is among the most rewarding and important aspects of her role as a faculty member. “Our jobs as faculty are to do good science and make good scientists,” she said. “I believe the Keck Foundation shares this belief and sees the potential positive impact this project can have.”
