Time to Act to Reduce Short-lived Climate Pollutants (SCLP), 2014. UNEP.
Large-scale implementation of these SCLP measures by 2030 would likely prevent 2.4 (0.7–4.6) million premature deaths from outdoor air pollution annually and avoid annual crop yield losses of over 50 (30–135) million tons, which represents an increase of a up to 4% of the total annual global crop production. Implementation could also slow down the warming expected by 2050 by about 0.5°C (UNEP & WMO 2011) – and by about 0.7°C in the Arctic by 2040 – and could have significant regional climate benefits in sensitive regions of the world, reducing disruption of rainfall patterns and slowing the melting of some glaciers (WB & ICCI 2013). Action to reduce the climate impacts of HFCs, such as using hydrocarbon refrigerants in domestic refrigerators, freezers and small air conditioning units, could deliver additional near term climate change mitigation benefits.
