# National systems for policies and measures and greenhouse gas projections, 2025

National systems include all relevant institutional, legal and procedural arrangements established within a country for reporting on greenhouse gas emissions policies and measures, for evaluating policy, and for making projections of anthropogenic greenhouse gas (GHG) emissions by sources and removals by sinks. Countries have to operate a national system, while also seeking to continuously improve it. Within the EU climate governance framework, national systems serve as the backbone for planning, monitoring, and reporting processes. A complete and transparent national system is essential to deliver good-quality information on GHG projections to integrate policy effects and understand GHG emission trends. It seeks to ensure the timeliness, transparency, accuracy, consistency, comparability and completeness of the information on policies and measures and GHG projections. 

The dataset covers all EU Member States, as well as Iceland, Switzerland and Norway. The data had to be reported in 2021, in line with Article 39 of the Governance of the Energy Union and Climate Action Regulation (EU) 2018/1999; however, each year a country can update data related to national systems, if modifications to the information exist. Therefore, some countries update data annually. Data is officially reported by national administrations and it is collected via the European Environmental Agency’s survey tool Reportnet 3.https://sdi.eea.europa.eu/geonetwork/srv/api/records/c3b32fa8-0497-4a51-bc2a-f66574a28e5d
