Combating Short-Lived Climate Pollutants (SLCPs)
You encounter them every day: soot from auto exhaust and burning wood (black carbon), gases that make refrigerators and air conditioners cool (hydrofluorocarbons), natural gas that makes your stove work (methane), and ground-level ozone formed by sunlight and fossil-fuel emissions. Short-live climate pollutants are all around us. And controlling them holds great potential in the fight against climate change.
Short-lived climate pollutants (SLCPs) are so named because they last a relatively short time in the atmosphere, from a few days to a few decades. In contrast, carbon dioxide (CO2) can last centuries. Yet they’re a major contributor to climate change, degrade air quality, and have grave impacts on food security and the health of the world’s most vulnerable populations.
According to the Intergovernmental Panel on Climate Change, SLCPs are responsible for more than 30 percent of global warming (more recent studies estimate their contribute to be as high as 45 percent).
Effective control of SLCPs could create significant progress in the near-term fight against climate change, buying time to implement long-term solutions. It could also mean better air quality, a reduction in premature deaths from respiratory and heart disease, and improved crop yields.

Short-lived climate pollutants: An opportunity to reduce emissions
AIDA together with CEDHA, CEMDA and RedRacc have produced a briefing paper on short-lived climate pollutants (SLCPs) for presentation at the 19th Conference of the Parties (COP19) on climate change, which is running November 11 to 22 in Warsaw, Poland. SLCPs are agents that contribute to global warming and have a relatively short lifetime in the atmosphere, from a few days to a few decades. That’s different from CO2, which remains in the atmosphere for centuries or millennia after emission. CO2 contributes an estimated 55% to 60% to global warming, while the remaining 40-45% comes from the emission of SLCPs. The latter seriously affect human health and ecosystems, meaning that any reduction in their emissions also brings significant social benefits. The fact that these contaminants remain so little time in the atmosphere means that their mitigation brings short-term benefits, in particular to the most vulnerable regions of the world already suffering the impacts of climate change. We must seize the opportunity to reduce SLCPs in the fight against the effects of this global challenge. Our paper explains what SLCPs are, which are the most relevant ones, and what are the reasons we should work to regulate and reduce their emissions. The paper also provides recommendations for taking on the challenge. Read the Fact Sheet (in Spanish)
