The European Commission decided to send a letter of formal notice to Poland for failing to comply with its obligations under the Directive on Ambient Air Quality(Directive 2008/50/EC) and with the ruling delivered by the Court of Justice of the EU on 22 February 2018 (Commission vs Poland, C-336/16), in which the Court found that Poland had also breached its obligations under the Ambient Air Quality Directive.
While acknowledging that some progress has been made, the Commission remains concerned by the slow pace of changes and the lack of a coordinated approach at national and local levels, in particular with regard to the replacing of outdated solid fuel boilers used for heating by individual households and with regard to measures addressing the transport sector. Poland has two months to reply to the concerns raised by the Commission. Otherwise, the Commission may refer the case back with proposed financial sanctions to the Court of Justice of the EU.
