First Reason:
Delayed efforts to mitigate either carbon dioxide or short-lived climate pollutant emissions will have negative, and potentially irreversible, consequences for global warming, rising sea levels, food security, and public health.
Second Reason:
Due to their relatively short lifetime in the atmosphere, ranging from a few days to a few decades, reducing short-lived climate pollutants can rapidly slow the rate of global temperature rise, complement efforts to mitigate carbon dioxide emissions and keep warming below 2°C.
Third Reason:
The Climate and Clean Air Coalition’s measures can cut methane emissions by at least 40% and black carbon by up to 70% by 2030, and virtually eliminate (99.5%) high-global warming potential hydrofluorocarbons altogether by 2050 (all compared to 2010 levels).
