Review of global agricultural emission databases

Since the Industrial Revolution, the concentration of greenhouse gases (GHG) has consistently risen, leading to a 1.15°C increase in global mean temperatures by 2022. The Intergovernmental Panel on Climate Change (IPCC) confirms human activities as the primary cause of global warming, with emissions continuing to rise. Climate change has resulted in adverse impacts on various fronts, disproportionately affecting vulnerable communities. International efforts, including the United Nations Frame-work Convention on Climate Change (UNFCCC) and its Kyoto Protocol, aimed at stabilizing green-house gas concentrations. These efforts were followed by the Paris Agreement in 2015, focusing on limiting global temperature increases and relying on Nationally Determined Contributions (NDC) from countries. The United Nations Framework Convention on Climate Change mandates Countries to develop and regularly update national inventories of greenhouse gas emissions and removals. These inventories, aligned with IPCC methodologies, serve as crucial tools for transparent reporting, building mutual trust among countries for effective climate change agreements. National GHG inventories play a vital role in policy development, monitoring impact, and tracking progress toward achieving NDCs outlined in inter-national agreements, such as the Paris Agreement. Varying capacities for GHG inventory development among developing and developed countries, coupled with diverse reporting requirements, create challenges in data comparability. Developed countries face rigorous annual submission requirements, producing comprehensive National Inventory Reports and Common Reporting Format tables. In contrast, developing countries submit their national GHG inventories through Biennial Update Reports (BURs), and flexibility is granted to Least Developed Country Parties (LDCs) and Small Island Developing States (SIDS) regarding submission timelines. The re-porting landscape is progressing, with the introduction of the biennial transparency report (BTR) for Paris Agreement Parties. The BTR, due by December 31, 2024, will convergence in methodologies be-tween countries.
