Bridging the Gap: The Role of Short-Lived Climate Pollutants

The document discusses the role of short-lived climate pollutants (SLCPs) in closing the 'emissions gap'—the difference between current Nationally Determined Contributions (NDCs) and the trajectories needed to keep global temperature rise below 2°C or 1.5°C. It identifies methane, tropospheric ozone, black carbon, and hydrofluorocarbons as primary targets for reduction, noting that while some strategies target single pollutants, most affect multiple. The text emphasizes that SLCP reductions, especially when combined with CO2 reductions, can limit long-term warming.

• The 'emissions gap' is defined as the disparity between emission trajectories resulting from the implementation of Nationally Determined Contributions (NDCs) and those required to align with temperature targets like the 2°C goal.
• Effective strategies for reducing short-lived climate pollutants (SLCPs) primarily target hydrofluorocarbons, black carbon, tropospheric ozone, and methane, whereas cooling agents like organic carbon and sulphur dioxide are not targeted.
• Reducing SLCPs can assist in limiting long-term warming and closing the emissions gap, particularly when these efforts are paired with reductions in CO2.
