Super Pollutant Seminar - The Imperative for Action

Last year was confirmed as the first year in which global average temperatures exceeded 1.5 °C, and air pollution impact on human health was revised upwards, with 8 million people dying early from air pollution every year, making it the second largest risk factor for ill health.  

Despite these worrying trends, 2025 represents a unique opportunity to begin to reverse them through action on super pollutants – methane, black carbon, hydrofluorocarbons (HFCs), tropospheric ozone, and nitrous oxide – that drive both climate change and air pollution. 

These crises are deeply intertwined—and so are their solutions. 

 Analysis and scientific assessment conducted by the leading scientists and experts on super pollutants of the Climate and Clean Air Coalition show thatsuper pollutants like methane and nitrous oxide contribute half of today’s climate change, but actions to reduce these pollutants are dramatically underrepresented in national climate plans. As Governments work to update their plans before COP30 in Brazil, increasing action on super pollutants is a key response to climate change that can boost climate change mitigation ambition and bring a broad range of health, economic, food security and development benefits.  

By acting quickly to reduce super pollutants, countries can accelerate climate progress, prevent millions of premature deaths, and unlock far-reaching economic, food security, and development benefits. The science is clear, and the tools exist—what’s needed now is political will and implementation at scale. 

Join us to hear fromand discuss withleading scientists and policymakers from around the world why fast action on super pollutants is critical – and how we can get it done. Hosted by the Climate and Clean Air Coalition and London School of Hygiene & Tropical Medicine, this event will dive into the latest science, tools, and strategies for slashing super pollutants and delivering immediate benefits for climate, clean air, and public health. 

Stick around after the event for a networking lunch to continue the conversation. 

This session will be part of a broader event taking place at the London School of Hygiene & Tropical Medicine: ‘From global evidence to local action on climate and health’. 

Attendees are welcome to join for both sessions of the event (starting at 9.30am), or join for this session only from 11.30am.
