CCAC assessments Demonstrating the multiple benefits of integrated climate and clean air action Share SHARE Facebook share Twitter LinkedIn Copy URL Email Breadcrumb Home CCAC Assessments 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. 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 report, HFCs: A Critical Link in Protecting Climate and the Ozone Layer, form the basis for our work. We continue to build upon existing assessments to generate targeted data and information on short-lived climate pollutant emissions, impacts, and mitigation opportunities. Our integrated assessments on these pollutants provide a framework for national action and regional cooperation on mitigation efforts. Assessments are more than just a report. Developing an assessment involves engaging governments, local policymakers, scientists, technical experts, and other key stakeholders in a well-structured consultation process. Through this process, we aim to strengthen the synergies between existing science and policy initiatives and ultimately support ambitious national and regional action. Global Methane Assessment Image The findings in this assessment are the result of modelling that uses five state-of-the art global composition-climate models to evaluate changes in the Earth’s climate system and surface ozone concentrations from reductions in methane emissions. Results allow for rapid evaluation of impacts from methane emissions and the benefits from mitigation strategies to the climate and ground-level ozone formation and air quality, public health, agricultural and other development benefits. The assessment results are also available in a web-based decision support tool that allows users to input different methane emissions reduction goals to calculate the multiple benefits at a national level.

It examines the role that short-lived climate pollutants, greenhouse gases, and other polluting emissions play in sustainable development. It analyses strategies, policies, and measures to mitigate these pollutants while supporting development and human health and wellbeing in Africa as the continent adapts to climate change and pursues its sustainable development objectives over the next four decades. The Assessment was written by a pan-Africa team with contributions from international scientists and experts, and has helped build a regional science to policy network. Read more Air pollution measures for Asia and the Pacific Image This report aims to support efforts to address air pollution in Asia and the Pacific by providing options for tackling air pollution in the context of the SDGs. To this end, it brings together evidence of historical trends with future development perspectives and provides detailed analyses of past and future economic trends and their implications for ambient and indoor air pollution.From there, the report identifies a detailed portfolio of 25 cost-effective measures for technological and policy interventions that would contribute to the achievement of the SDGs while delivering the greatest benefits for human health, crop yields, climate and the environment, as well as socio-economic development. The report provides a clear picture of the benefits to be gained by adopting the measures and offers some implementation guidance through real-life case studies. Read more Global Nitrous Oxide Assessment Image Nitrous oxide, considered to be a super pollutant, is the third most important greenhouse gas and the most significant ozone-layer depleting substance emitted today. Its human-induced emissions, which primarily originate from the agricultural use of synthetic fertilisers and manure, are increasing faster than previously projected. This Assessment identifies abatement measures available today that could reduce these emissions by more than 40 per cent below current levels.Read more Download our assessments Previous Next Reports, Case Studies & Assessments 2022 Global Methane Assessment: 2030 Baseline Report Reports, Case Studies & Assessments 2021 Global Methane Assessment (full report) Reports, Case Studies & Assessments 2022 Summary for Decision Makers - Integrated Assessment of Air Pollution and Climate Change for Sustainable Development in Africa Air Pollution in Asia and the Pacific: Science-based solutions Emissions assessments, National policy and planning Air Pollution in Asia and the Pacific: Science-based solutions Guidelines & Tools 2019 25 clean air measures for Asia and the Pacific Reports, Case Studies & Assessments 2018 Integrated Assessment of Short-lived Climate Pollutants in Latin America and the Caribbean
