2027 IPCC Methodology Report on Inventories for Short-lived Climate Forcers
About Project
The 2027 IPCC Methodology Report on Inventories for Short-lived Climate Forcers (SLCFs) is an international initiative led by the Intergovernmental Panel on Climate Change (IPCC) to develop globally consistent methodological guidance for estimating and reporting national emissions of short-lived climate forcers. The report is intended to support countries in preparing transparent, accurate, and comparable emission inventories that complement existing IPCC greenhouse gas inventory guidelines.
The report will provide practical, science-based guidance for key short-lived climate forcers, including nitrogen oxides (NOx), carbon monoxide (CO), non-methane volatile organic compounds (NMVOCs), sulfur dioxide (SO₂), ammonia (NH₃), black carbon (BC), organic carbon (OC), and particulate matter, which play critical roles in air quality degradation and climate forcing. It will cover methodologies for emission estimation, data collection and reporting, uncertainty assessment, quality assurance, and quality control (QA/QC).
By strengthening the methodological basis for SLCF inventories, the project will enhance countries’ capacity to assess the impacts of air pollutant emissions on climate change and air quality. The report will support evidence-based policymaking and improve the international consistency and comparability of emission data. Scheduled for publication in 2027, the report will serve as an authoritative reference for policymakers, inventory compilers, and technical experts worldwide.
This project is funded by the IPCC Trust Fund from the World Meteorological Organization (WMO) and the United Nations Environment Programme (UNEP), Thailand Science Research and Innovation (TSRI), and the National Science, Research and Innovation Fund (NSRF) via the Program Management Unit for Human Resources & Institutional Development, Research and Innovation [B41G680024].
