A new report by The European Court of Auditors finds that while European cities have cleaner air, they are still too noisy. The report states it proved difficult to assess progress made in reducing noise pollution - mainly due to gaps and delays in assessing and reporting on noise pollution by most EU member states. It also considers that the lack of EU noise reduction targets disincentivises member states to prioritise actions to reduce noise pollution effectively, and that the noise reporting thresholds only cover part of the EU population that may be exposed to harmful levels of noise.
