Periodic greenhouse gas (GHG) emissions inventories are key to determine the contribution of a country, jurisdiction or company to global warming over time, to evaluate the effect of mitigation measures and to assess compliance with mitigation goals or commitments. Under the UNFCCC, all countries are required to submit national inventories of anthropogenic emissions by sources and removals by sinks of all GHG not controlled by the Montreal Protocol, although the reporting requirements and the timetable for the submission of national reports containing such inventories are different for Annex I Parties and developing countries, in accordance with the principle of common but differentiated responsibilities and respective capabilities.

Consequently, national GHG inventories are developed following the reporting guidance agreed by the Conference of the Parties (COP) to that end for each group of Parties using good practice methodologies accepted by the IPCC and agreed upon by the COP. The COP has also established review and analysis procedures for the submitted GHG inventories, which are part of the UNFCCC´s Monitoring, Reporting and Verification (MRV) framework.
