About

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.

Top facts

Significant portion of avoided premature deaths in 2030 avoided due to implementation of identified SLCP emission abatement measures will accrue in Asia and Africa.

Objectives

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.

Achievements to date

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: 
   

  • Launching in November 2018 the Asia Pacific Regional Assessment, Air Pollution in Asia and the Pacific: Science-based solutions. Several partner countries and organizations have started using the recommended 25 clean air measures to frame their work to improve air quality support, including:   
    • The Asia Pacific Issue-Based Coalition of Climate Change Mitigation and Air Pollution co-led by UNEP and UNESCAP have advised UN agencies to use 25 clean air measures in framing their own interventions on air quality 
    • World Health Organization is including the 25 clean air measures in its proposal for "best-buy interventions" to address air pollution as a non-communicable disease risk.   
    • A new project under the Korea-ESCAP Cooperation Fund will implement the 25 clean air measures in three cities: Hanoi, Jakarta, and Chiang Mai.    
    • The new vision for Asian Co-Benefits Partnership (ACP) will focus on facilitating the implementation of integrated air quality and climate solutions in Asia, using the 25 clean air measures to frame the solutions.  
    • UNEP’s Asia Pacific Office and APCAP are developing a “Clean Air Solutions Tracker” to track country up-take of solutions from the Asia-Pacific Regional Assessment.   
  • The Latin America and Caribbean (LAC) Assessment, and a technical report reviewing examples of successful short-lived climate pollutant measures from LAC countries, was released in 2017. They showed how implementing these measures could reduce warming in the region by up to 0.9˚C by 2050, reduce premature deaths from PM2.5 by at least 26% annually, and avoid the loss of up to 4 million tonnes of crops each year. 
    • Ministers of Environment of Latin America and the Caribbean issued a decision – the Cartagena Pledge – noting that reducing air pollution goes hand in hand with reducing both short-lived and long-lived climate pollutants and can support the achievement of climate mitigation and adaptation goals and commitments. It decided to make strategic use of information from the assessment and encourage action to address air quality and climate change.
    • CCAC Scientific Advisory Panel member Dr. Graciela Binimelis de Raga presented the conclusions of the assessment at the XVI General Assembly of the Parliamentary Confederation of the Americas. As a result, Ministers ratified a Declaration on Short-lived Climate Pollutants

FAQ

Why are assessments at the regional level important?

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.

How can my organization get involved in the Regional Assessment Initiative?

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
