Both Poland and Belgium have failed to transpose into national law the 2008 EU air quality directive. Consequently, the European Commission has sent a reasoned opinion to Poland, while Belgium is receiving a second reasoned opinion. In case Poland and Belgium do not comply, the Commission may refer them to the Court of Justice and may already ask the Court to impose financial sanctions.
According to the Commission, Latvia has failed to effectively tackle PM10 pollution, and the daily concentration limit values have not been respected in all zones in Latvia since the legislation was adopted in 1999 and became binding in 2005. While Latvia has applied for time extension for one zone, the Commission considers that the conditions for granting it have not been met. Therefore a reasoned opinion was sent, and Latvia has two months to take appropriate action.
