The efforts of the EU member states to achieve their ambitious climate targets have not yet been sufficient. This is not only revealed by the inadequate national energy and climate plans of the EU member states (NECP), which show gaping holes, particularly in measures against transport and building emissions, to achieve the 2030 targets. Now the European Science Advisory Board on Climate Change (ESABCC) has also criticized that there are shortcomings in existing and planned legislation relating to the EU’s climate neutrality targets for 2050.
