Aether is supporting the Romanian National Research and Development Institute for Cryogenic and Isotopic Technologies (ICSI) in the compilation of the Romanian national greenhouse gas (GHG) emissions inventory for non-forest land areas. We are helping to ensure that Romania’s land use, land use change and forestry (LULUCF) inventory is robust and of high quality.
Romania is required to report GHG emissions data to the European Union and under the United Nations Framework on Climate Change (UNFCCC). The new team at ICSI have been responsible for compiling emission and removal GHG estimates from non-forest land areas since September 2019. These non-forest land areas are classified under cropland, grassland, wetlands, settlements, and other land. The key challenges for the ICSI team were:
ICSI engaged Aether to assist with improving the estimates and reporting of emissions and removals associated with non-forest land uses and to increase the capacity of the national team.
Aether has been supporting ICSI since 2020. The first task was to create a new tool for calculating emissions and removals from the non-forest land LULUCF sectors that was transparent and user-friendly. The next stage of the work focused on making improvements to the compilation file in terms of accuracy, transparency and completeness through better documentation, additional QA/QC and structuring. Aether staff used their experience with the UNFCCC reviews to conduct a full methodology review to ensure that the estimates are in line with current reporting requirements and best practice from the 2006 IPCC Guidelines. As part of this work, Aether also supports ICSI to analyse the uncertainty of GHG estimates from the non-forest land.
A key aspect to delivering this work was to build the capacity of the new national team through providing hands-on training and a technical review of the outputs they prepared for reporting.
ICSI has a new compilation tool for estimating GHG emissions and removals from non-forest land areas which:

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.

The Aether team is supporting reviews of air pollutant and greenhouse gas inventories for several European countries, including under the NECD, ESR, and LULUCF regulations. These reviews ensure accurate emissions data to meet EU targets for 2030. The team is also helping build capacity in countries needing extra support, contributing to cleaner air and better climate policy implementation across Europe.
