According to the European Commission, numerous EU states have not yet transposed several recently enacted laws into national legislation. Germany, too, apparently faces challenges in implementing four laws. This includes the reform of the EU Emissions Trading System (ETS). In total, 26 countries (all except Denmark) have not reported full implementation of the revision of the ETS, which became effective in May 2023, by the deadline of December 31, 2023, the Commission said. The revision includes the expansion of the ETS to maritime transport and the introduction of a second ETS for building heating and transportation.
