The emission reduction obligation of the EU Member State is jointly implemented through the European Emission Trading System (EU ETS). A common 'cap' was established for the EU ETS system, in which 52 facilities from Croatia are also included. The emissions and sectors not covered by the EU ETS, the annual national allocation quotas are determined for the Member States and they must not be exceeded. These quotas are established on the basis of solidarity. A debate on the Proposal for a Regulation on binding annual greenhouse gas emission reductions by Member States from 2021 to 2030 for a resilient Energy Union and to meet commitments under the Paris Agreement has finished and the publication in the Official Journal of the EU is expected soon, and for the Republic of Croatia the goal of reducing emissions by 7 % compared to the 2005 level is determined. The EU set a goal of reducing emissions by at least 80 % compared to 1990 in 2050 in the Roadmap for the transition to a low-carbon economy by 2050 (COM (2011) 112).
