In a landmark collaboration announced on November 4, 2025, the Wellcome Trust, one of the world’s largest biomedical research funders, has forged a three-year strategic partnership with the United Nations Climate Change Secretariat (UNFCCC). This alliance aims to propel health-centered climate solutions to the forefront of global policy agendas, with a particular emphasis on accelerating investments in sustainable food systems and clean energy transitions. Coming just days before the critical COP30 climate conference in Brazil, the partnership underscores a growing recognition that climate action cannot succeed without prioritizing human health outcomes, especially for vulnerable communities in the Global South.
The initiative, launched in Bonn and London, responds to the escalating health crises exacerbated by climate change, including extreme heatwaves, air pollution, infectious disease outbreaks, mental health strains, and food insecurity. Wellcome Trust CEO John-Arne Røttingen emphasized the need for inclusive multilateralism, stating that the UN’s role in facilitating global negotiations is indispensable for embedding scientific expertise and affected communities’ voices into actionable policies. “We will work together to ensure that health evidence strengthens international and national climate strategies,” Røttingen said, highlighting the partnership’s focus on both mitigation—reducing emissions—and adaptation—building resilience against inevitable impacts.
At its core, the partnership targets sectors where health and climate intersect most acutely: sustainable food production and renewable energy. Food systems, responsible for about one-third of global greenhouse gas emissions, are undergoing rapid transformation due to climate pressures like droughts and floods, which threaten crop yields and nutritional access. Wellcome’s longstanding investments, such as the Sustainable and Healthy Food Systems (SHEFS) program led by Professor Alan Dangour of the London School of Hygiene & Tropical Medicine, have already demonstrated how shifting to climate-resilient agriculture can yield dual benefits: cutting emissions while improving diets and reducing diet-related diseases. SHEFS collaborates with policymakers to co-develop strategies for nutritious, low-impact food environments, addressing challenges from farm to fork.
Under the new UN partnership, these efforts will scale up through joint advocacy at forums like COP30, where delegates will negotiate enhanced Nationally Determined Contributions (NDCs) under the Paris Agreement. The collaboration will support evidence-based interventions, such as promoting agroecological practices that enhance soil health and biodiversity, thereby safeguarding food security for millions. For instance, projects funded by Wellcome’s Our Planet, Our Health initiative are exploring managed aquifer recharge (MAR) techniques to secure clean water for agriculture, assessing their health benefits amid projected environmental shifts. By integrating UN resources, these innovations can reach more regions, particularly in sub-Saharan Africa and South Asia, where smallholder farmers face the brunt of climate variability.
On the energy front, the partnership prioritizes clean energy solutions to combat air pollution, a silent killer responsible for seven million premature deaths annually according to WHO estimates. Fossil fuel combustion not only drives climate change but also worsens respiratory illnesses and cardiovascular conditions, disproportionately affecting urban poor and children in developing nations. Wellcome’s vision aligns with UN goals to transition to renewables like solar and wind, which can lower the “green premium”—the cost gap between clean and dirty energy—through targeted R&D. The trust’s funding for transdisciplinary teams under the G7 Climate Mitigation Policy Solutions scheme is generating data on health co-benefits, such as reduced asthma rates from electrified transport and housing retrofits. These insights will inform UN-led policy toolkits, enabling countries to quantify economic returns on green investments, from job creation in renewable sectors to avoided healthcare costs.
This alliance builds on Wellcome’s broader climate-health portfolio, which includes a £37.6 billion endowment dedicated to challenges like infectious diseases amplified by warming temperatures—malaria vectors expanding northward, for example. Recent grants under the Climate Impacts Awards fund short-term projects synthesizing data on mental health tolls from climate disasters, combining research with public engagement to amplify policy demands. Partnering with the UN amplifies this by embedding Wellcome’s evidence into the UNFCCC’s Loss and Damage Fund mechanisms, ensuring funds flow to health-resilient infrastructure in low-income countries.
Critics and supporters alike see this as a timely pivot amid funding shortfalls. Philanthropic commitments like Wellcome’s $25 million to WHO’s climate-health work earlier this year pale against the $100 billion annual climate finance pledge from rich nations, which remains unmet. Yet, the partnership’s emphasis on empowerment—training local leaders in evidence advocacy—could catalyze private sector involvement. For sustainable food, this means incentivizing investments in plant-based alternatives and precision farming tech; for energy, it involves scaling microgrids in off-grid communities to prevent heat-related deaths.
The announcement has drawn praise from global health advocates. Patricia Espinosa, former UNFCCC Executive Secretary, called it “a beacon for solutions-oriented diplomacy,” while environmental groups like Greenpeace urge bolder emission targets. Challenges remain: integrating diverse stakeholder voices to avoid top-down impositions, and measuring long-term impacts in data-scarce regions. Nonetheless, by fostering synergies across UN agencies like FAO and WHO, the partnership positions health as the linchpin for equitable climate action.
Looking ahead, this collaboration could redefine COP outcomes, pushing for health metrics in NDCs and unlocking blended finance for green projects. Wellcome’s involvement with coalitions like the one launched with The Rockefeller Foundation further amplifies reach, pooling resources for Asia-Pacific initiatives where urbanization strains food and energy systems. As Røttingen noted, “No one should be left behind in this transition.” With COP30 looming, this UN-Wellcome pact signals a healthier, more sustainable trajectory, where investments in resilient food and clean energy not only curb warming but also foster thriving communities worldwide.
Early indicators of momentum include pilot programs in Brazil, host of COP30, where Wellcome-UN teams are modeling health gains from Amazonian reforestation tied to sustainable cattle farming—reducing methane emissions while preserving indigenous nutrition sources. In India, joint efforts target solar-powered cold chains to cut food waste, a move projected to save 1.5 billion meals annually and slash related emissions. These vignettes illustrate the partnership’s practical edge, blending rigorous science with on-ground implementation.
Economically, the stakes are immense. A 2021 Wellcome report estimated that aligning food, energy, and transport with Paris goals could avert 2.4 million air pollution deaths by 2040, while boosting GDP through green jobs. The UN partnership will commission updated modeling, incorporating mental health costs—often overlooked at $1 trillion yearly globally—to make the case irrefutable for investors. Philanthropy Asia Alliance’s involvement hints at mobilizing Asian donors for region-specific funds, bridging gaps in equitable tech transfer.
Skeptics warn of greenwashing risks if corporate polluters co-opt the narrative, but Wellcome’s insistence on community-led design mitigates this. By 2028, the partnership aims to influence 50 national policies, tracking progress via open-access dashboards. In an era of geopolitical fractures, this health-climate bridge exemplifies multilateralism’s enduring power, proving that targeted investments in sustainable food and energy can heal both planet and people.
