Super-Pollutant Cuts Could Save $1.5 Trillion a Year, Experts Tell Finance Ministers

Experts at the UN-hosted Climate and Clean Air Coalition meeting in Bangkok are urging finance ministers to treat super-pollutants like methane, black carbon, and HFCs as an emergency brake on global warming. Cutting these short-lived climate pollutants could avoid 0.34°C of warming by 2050 and reduce air pollution deaths from a projected 15 million a year back to roughly 5 million by 2100. The CCAC's Hidden Assets report puts the global economic gain at $1.5 trillion annually, against an estimated $9 billion a year in action costs. The push comes ahead of COP31 in Antalya, where experts want a formal roadmap for integrating clean air measures into national climate pledges. Methane is the priority because it traps heat far more powerfully than CO2 and reacts to form ground-level ozone. The article notes that while CCAC is a voluntary partnership, countries are increasingly writing super-pollutant measures into their NDCs, and the health and economic benefits can show up within one political cycle.
