Under the UNFCCC, Rwanda is classified as a non-Annex I party, and is required to submit National Communications (NCs) and Biennial Update Reports (BURs) at regular intervals. BURs must be prepared to a high standard ready to undergo an international consultation and analysis (ICA) process which includes a technical analysis on the transparency of mitigation actions and their effects. Rwanda required support during the compilation of its first BUR to ensure that the GHG inventory and mitigation assessments were in line with international best practice.
As part of the production of the first BUR, a national GHG inventory was compiled and mitigation actions assessed for four sectors in Rwanda; Energy, Industrial Processes and Product Use (IPPU), Agriculture, Forestry and Other Land Use (AFOLU) and Waste.
Emma collaborated with the national experts that compiled the GHG inventory and mitigation assessments to provide Quality Assurance (QA) in line with international best practice. The mitigation assessments were compared against the ICA criteria to check alignment with reporting expectations. The GHG inventory chapter of the BUR and the accompanying National Inventory Report (NIR) were also reviewed with the benefit of 10+ years of international experience.
Rwanda submitted its first BUR to the UNFCCC in 2021, with its national GHG inventory and mitigation assessments checked in line with international best practice. A NIR containing in depth detail of the GHG inventory compilation process was also checked and submitted. National experts in Rwanda received technical guidance and support through one-to-one discussions and in-depth feedback on documents and calculations.

The air pollutant emissions inventories for England, Scotland, Wales, and Northern Ireland were published in September 2025. The data covers the period 2005 to 2023, for the pollutants ammonia, carbon monoxide, nitrogen oxides, non-methane volatile organic compounds, PM10, PM2.5, sulphur dioxide, and lead. In addition, experimental inventory statistics are presented for emissions of benzo[a]pyrene, dioxins and furans, and mercury.

In the first week of October Richard Claxton and Sergii Shmarin were in Istanbul, contributing as lead authors to the upcoming IPCC Methodology Report on Short-Lived Climate Forcers (SLCFs). SLCFs - such as black carbon, and other ozone precursors play a critical role in climate change and air quality. The new methodology report will provide essential guidance for countries to improve their emissions inventories and strengthen climate action.
