The EU Air Quality Directive (2008/50/EC) requires that all member states hit targets to reduce the main air pollutants in congested urban areas – particularly nitrogen dioxide and particulate matter PM10- by 2015.
The UK was expected to reduce air pollution in most regions of the country, but on May 1st this year the Supreme Court of Justice declared that the plans are on course for failure. Originally the targets were supposed to be met by 2010 but the government asked for a postponement of the deadline. In June 2011 a draft of air quality plans was submitted by the government, and final plans were submitted – including a request for time extension- in September 2011 where it was said that limit values in 16 zones including London would be met by January 2015. Since then further plans have been submitted showing possible compliance between 2015 and 2025, however no official request for this time extention was made.
Maria Arnold, from campaign group ClientEarth, who brought the court case to the Supreme Court, said:
“The Supreme Court’s declaration sent a very strong message to government. As yet we have not seen any evidence that Defra have increased their commitment to tackling this issue, in fact their source in the media was quoted as saying ‘Air quality has improved significantly in recent decades and almost all of the UK meets EU air quality limits for all pollutants,’ which we do not think is an adequate response.
The Secretary of State must produce plans to ensure compliance in 16 regions and cities – including London- as soon as possible “.
Now ClientEarth are awaiting for the ultimate decision of the UK Supreme Court and eventually the response from the Court of Justice of the European Union, while no official comment from Defra was released.
According to recent reports, London is not the most polluted capital in Europe but remains one of the cities where air quality is considered an emergency. In 2011, a overview by Soot Free Cities that ranked major cities in Europe was based on the measures taken by local authorities to improve air quality and the overall emission reduction success. London came 11th out of 17.
According to the latest EEA report, the UK is among the european countries closer to reach the Gothemberg targets in PM10 emissions and NO2 emission in the country decreased 15/20 % between 1990 and 2010.
However still much work is to be done and the final decision of the Supreme Court followed by the response of Court of Justice of EU might really start a new process of plans to improve air quality in UK.
Maria Arnold said: “We need a mixture of national and local action. The Mayor of London could and should be doing a lot more to address the problem of air pollution but ultimately the UK government need to show far more leadership in order to support and drive local action.”
