The Czech Republic, like all states that are parties to the United Nations Framework Convention on Climate Change (UNFCCC), is obliged to implement international measures to mitigate climate change caused by anthropogenic activities, within the framework of which it must also regularly publish projections of greenhouse gas emissions. By reporting projections, the Czech Republic also fulfils its obligations as an EU Member State under Article 18 of Regulation 2018/1999. The Czech Hydrometeorological Institute (CHMI) is responsible for the implementation and submission of these reports and reports every two years, on 15 March (t-2), to the European Commission and the UNFCCC Secretariat, which then use them to develop further legislation and policy measures to reduce emissions or increase sinks (removals) of greenhouse gases.
