Short-lived climate pollutants (SLCPs) – such as methane, black carbon, tropospheric ozone, and some hydrofluorocarbons – are a subset of greenhouse gases and aerosols that contribute to global warming and remain in the atmosphere for relatively short time periods. Reducing global SLCP emissions is important for mitigating near-term climate change, and can complement strategies aimed at reducing emissions of long-lived greenhouse gases
, primarily carbon dioxide. SLCPs are also air pollutants that negatively affect human health, ecosystems, and agriculture.
According to the United Nations Environment Programme and World Meteorological Organization
, near-term mitigation of SLCPs could prevent:
A global temperature increase of 0.5° C/ 0.9° in 2050;
2.4 million premature deaths from pollution; and
30 million metric tons of annual staple crop losses.
Abt Associates supports efforts to reduce SLCP emissions through a range of analytical, capacity building, communications, and outreach activities that span multiple sectors
and regions. For example, Abt has assisted clients in:
Developing tools for estimating and tracking SLCP emissions from different sectors and sources;
Analyzing the impacts of SLCP emissions on temperature changes;
Coordinating capacity building trainings for government agencies and their stakeholders to share best practices for SLCP mitigation;
Researching and synthesizing state-of-the-science knowledge about SLCP emissions, their impacts on climate and health, and potential mitigation benefits; and
Designing customized infographics, posters, fact sheets, webinars, and presentations to communicate about SLCPs to a wide range of audiences.
Abt’s efforts in this field directly contribute to significant international SLCP-focused initiatives, including the Climate and Clean Air Coalition to Reduce Short Lived Climate Pollutants
, the Global Methane Initiative
, and the Arctic Council Task Force on Short-lived Climate Forcers
. Our work on SLCPs also supports a range of domestic U.S. government efforts, including the President’s Climate Action Plan
