The availability of robust and policy-relevant science on short-lived climate pollutants (SLCPs) at the global level, including on their climate and air quality impacts and actionable measures for reducing emissions, played a critical role in the establishment of the Climate and Clean Air Coalition (CCAC). The recommendations in the United Nations Environment Programme (UNEP) /World Meteorological Organization (WMO) UNEP/WMO Integrated Assessment of Black Carbon and Tropospheric Ozone; the UNEP synthesis report on Near-term Climate Protection and Clean Air Benefits, as well as the synthesis report on Hydroflourocarbons HFCs and their links to climate change and ozone layer depletion form the basis for the initiatives and activities of the Coalition.
While the above assessments and much of the available science provide information on SLCPs at the global level, experience has shown that implementing SLCP emission reduction measures requires a more complete picture of the regional and local circumstances than can be provided in a global assessment. It is therefore important to provide information and data at the regional and national levels. This will help ensure the identification, prioritization, and effective implementation of emission reduction measures tailored to the situation in different regions.
The goal of the Regional Assessments Initiative is therefore to build upon existing assessments to generate regionally-targeted data and information on SLCP science and mitigation opportunities. The initiative aims to develop scientifically robust and policy-relevant integrated assessments on SLCPs for key regions that will provide a framework for national action and underpin regional co-operation on SLCP emission reduction.
More than just a report, the process of developing the regional assessments will involve engaging governments, local policymakers, scientists, technical experts, and other key stakeholders in well-structured consultation process. Through this process, the Initiative aims to strengthen the synergies between existing science and policy initiatives in different regions and ultimately ambitious national and regional action on mitigation of SLCP emissions.
