De Climate and Clean Air Coalition to Reduce Short-Lived Climate Pollutants van het Milieuprogramma van de Verenigde Naties schat dat snelle actie om de hoeveelheid SLCPs in de lucht, vooral methaan en roet, te verminderen, de opwarming van de aarde die in 2050 wordt verwacht met 0,5 graden Celsius kan terugdringen.
The United Nations Environment Programme’s Climate and Clean Air Coalition to Reduce Short-Lived Climate Pollutants estimates that fast action to reduce SLCPs, especially methane and black carbon, has the potential to slow down the warming expected by 2050 by as much as 0.5º Celsius.
