The availability of robust and policy-relevant science on short-lived climate pollutants played a critical role in the establishment of the Climate and Clean Air Coalition (CCAC). The recommendations in the Integrated Assessment of Black Carbon and Tropospheric Ozone; the 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 these assessments and much of the available science provide information on short-lived climate pollutants at the global level, experience has shown that implementing emission reduction measures requires information and data at the regional and national levels.
The Coalition's Assessments Initiative is building upon existing assessments to generate regionally-targeted data and information on short-lived climate pollutant science and mitigation opportunities. The initiative is developing integrated assessments on these pollutants that will provide a framework for national action and underpin regional co-operation on emissions reduction.
Assessments are more than just a report. Developing a regional assessment involves engaging governments, local policymakers, scientists, technical experts, and other key stakeholders in a 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 support ambitious national and regional action.
The Assessments Initiative aims to identify scientifically robust short-lived climate pollutant emission reduction measures as well as policy actions that are relevant at the regional scale. It aims to create a platform for interaction and dialogue between science and policy with the ultimate goal of mobilizing ambitious national and regional support for action.
Through the development of regionally-targeted integrated assessments, the initiative seeks to close scientific data and information gaps, improve the understanding of local drivers of short-lived climate pollutant emissions, and identify local, context-appropriate and synergistic mitigation measures and policies.
The Assessments Initiative has completed assessments on short-lived climate pollutants for the Latin America and the Caribbean and Asia Pacific regions. Work on two new assessments was started in 2019: the regional African assessment that will consider the continent’s rapid development and the associated air pollution challenges and climate risks, and a global methane assessment.
Other key achievements include:
Lead Partner: A Coalition partner with an active role in coordinating, monitoring and guiding the work of an initiative.
Implementer: A Coalition partner or actor receiving Coalition funds to implement an activity or initiative.
Assessment at the regional level will provide scientifically robust and policy relevant foundation for action on SLCPs, tailored to the regional context. It will help bring together existing data at the regional scale that can help highlight the impacts of SLCPs and the benefits of reducing their emission. Further, a regional focused assessment can help identify mitigation measures that are relevant to specific regions or countries within a region which might not necessarily be relevant at the global scale. Furthermore, the process of consultation between scientists and policymakers in the region (which is one of the major activity in the development of the regional assessment) help increase ownership and build the political will to take action.
The Regional Assessment Initiative seeks to engage organizations and institutions with science and policy expertise in the various topics related to SCLPs including on emissions, inventory, mitigation measures, modelling, and policy solutions. The initiative is opened to interested parties that can contribute to on-going assessments including for Latin America and the Caribbean, Asia and the Pacific, as well as Africa. If your organization is interested in contributing, please contact the CCAC Secretariat.
