The European Commission has ordered Hungary, Romania, and 10 other member states to comply with EU air pollution legislation and reduce their emissions of several pollutants to reduce air pollution.

The EU executive sent a letter of formal notice to Luxembourg, Poland, and Romania, and a reasoned opinion to Bulgaria, Ireland, Cyprus, Latvia, Lithuania, Hungary, Austria, Portugal, and Sweden for failing to ensure the correct implementation of their commitments to reduce several air pollutants as required by Directive (EU) 2016/2284 on the national emission reductions of certain air pollutants (“NEC Directive”).
