GENEVA/BAKU — The climate crisis could disrupt HIV services and lead to increasing HIV risk for some of the most vulnerable populations, the Joint United Nations Programme on HIV/AIDS (UNAIDS) and United Nations Development Programme (UNDP) have warned at the COP29 Climate Conference in Baku, Azerbaijan. In a new report, the UN agencies warn that eroded public health infrastructure, heightened prevalence of diseases that interact with HIV, food insecurity, water scarcity, and the mass displacement of people – all likely to intensify due to climate change – could drive new HIV infections and lead to more AIDS-related deaths.

“The progress we have made tackling AIDS is fragile – and it could be unwound by runaway climate change,” said Winnie Byanyima, Executive Director of UNAIDS. “Some of the most climate vulnerable countries also have the highest HIV burden, and are the countries in the greatest debt, compounding injustice on injustice. We need to find ways to ease the triple funding crisis of AIDS, climate, and debt, and invest in the communities on the front lines of these intertwined crises.”

Many of the countries at the sharp end of climate change are also facing the worst impacts of the AIDS epidemic, and climate change is likely to exacerbate the inequalities of AIDS, UNAIDS says. Of the 4,000 adolescent girls and young women aged between 15 and 24 years newly infected with HIV every week, 3,100 live in Sub-Saharan Africa, where severe heatwaves and drought could leave whole regions uninhabitable.

HIV-focused institutions are responding, with 70% of financing from the Global Fund to Fight HIV, Tuberculosis and Malaria set to go to 50 of the most climate-vulnerable countries. But many of these countries are facing a triple funding crisis, with insufficient climate finance, a US$ 9.5 billion gap in HIV funding, and the crushing burden of sovereign debt.

Almost half of humanity live in countries spending more on servicing debt than on healthcare. In Western and Central Africa, countries are spending seven times more on repaying debt than on health. With 71% of public climate financing coming as loans rather than grants, the climate crisis will only make this problem worse.

Last year, Malawi was hit by Cyclone Freddy amid a cholera outbreak just as the nation was recovering from COVID-19. Some of the worst hit regions were those with the highest burden of HIV. Around 37 000 people living with HIV were displaced by the storm, forced to

navigate overwhelmed services and shortages of medicines – and this is just one of many examples of how climate change is already impacting the HIV response.

At the report launch on the sidelines of the COP29 Climate Conference in Baku, governments will be urged to tackle inequalities, build proper leadership and governance systems, and provide sustainable financing to prevent a climate-induced AIDS crisis.

“At COP29 we can see increasing recognition that the climate crisis is compounding existing health challenges” said Marcos Neto, Director, Bureau of Policy & Programme Support, UNDP. “The AIDS response has shown us what is possible when communities most impacted, governments and institutions unite. By embedding HIV and health considerations into climate action, we can protect hard-won progress, build resilience for the future, and leave no one behind.”
