Abstract
Short-lived climate forcers (SLCFs) are substances that remain in the atmosphere for a relatively short time — from days to decades — but still have a significant impact on the climate. Some, such as methane and black carbon (soot), contribute to warming, while others, such as sulphate particles, have a cooling effect. Together, these emissions have major implications for climate, air quality and public health. Reducing emissions of short-lived climate forcers is therefore an important part of the green transition.
