UN Says Climate Action Boosts Economy
UN report highlights economic benefits of tackling climate change and air pollution
Introduction To Climate Action And Air Pollution
The United Nations Environment Programme (UNEP) and the Climate and Clean Air Coalition (CCAC) have released a report highlighting the economic benefits of tackling climate change and air pollution together. According to the report, every US$1 invested in addressing these issues can generate around US$15 in economic benefits, including both market and nonmarket gains. This comprehensive global economic assessment, titled "Hidden Assets: The Economic and Health Case for Climate and Clean-Air Action," demonstrates that integrated climate and clean-air action can have a significant positive impact on the economy.
Background And Context
For a long time, climate action has been viewed as a cost to be managed, while air pollution has been seen as an unfortunate outcome of development. However, this report shows that clean air is a key driver of development, health, food and energy security, and climate stability. Inger Andersen, executive director of UNEP, emphasized that proven solutions to these problems already exist, but what is lacking is decisive leadership from governments, financial institutions, and businesses to deliver these solutions with the necessary speed and coordination.
Economic Benefits And Value
The report identifies 25 measures that can be implemented to address climate change and air pollution. The annual economic benefits of implementing these measures would be equivalent to 2.8% of global GDP in 2035, 4.5% of global GDP in 2050, and 11.4% of global GDP in 2100. In comparison, 2.18% of global GDP was spent on explicit fossil fuel subsidies in 2022, and 9.3% of global GDP was spent on health care in 2023. Every year of delayed action would result in a loss of more than US$1.5 trillion annually in combined market and nonmarket benefits.
Human Cost And Health Implications
The report also highlights the significant human cost of air pollution. In 2025, exposure to human-caused outdoor air pollution was linked to an estimated 6.4 million premature deaths worldwide, while household air pollution was linked to a further 2 million premature deaths. Additionally, outdoor air pollution contributed to 5.5 million new cases of childhood asthma, 2 million new cases of dementia, and millions of cases of heart attacks, pulmonary disease, diabetes, stroke, and lung cancer. The economic value of addressing these health issues is substantial, with every US$1 invested in tackling climate change and air pollution generating a return of around US$15.
Future Outlook And Implications
The report's findings have significant implications for governments, financial institutions, and businesses. By investing in integrated climate and clean-air action, these entities can generate substantial economic benefits while also improving public health and reducing the risks associated with climate change. As Elliott Harris, independent co-chair of the Assessment, noted, a benefit-cost ratio of 15-to-1 would attract capital instantly in almost any other sector. However, the returns on investment in climate and clean-air action are split across multiple sectors, making it essential to adopt a coordinated approach to addressing these issues.
