The European Commission is pursuing legal action against the UK for failing
to comply with EU air quality standards for dangerous airborne particles known
as PM10. These particles emitted mainly by industry, traffic and domestic
heating, may have negative effects on health leading to asthma, cardiovascular
problems, lung cancer and premature death. A second and final written warning
has been sent to the UK for still exceeding the limit values for PM10 in a
number of zones.
Environment Commissioner Janez Potočnik said: "Air pollution is bad
for our health. It reduces human life expectancy by more than eight months on
average and by more than two years in the most polluted cities and regions.
Member States must comply with EU air quality standards quickly and reduce air
Final warning for UK over PM10 levels
The Commission started this legal action because a number of zones in the UK
were exceeding the PM10 limit values in 2005, 2006 and 2007. The Commission is
now sending a final warning to the UK for breaching EU air quality standards.
According to the latest data provided, two areas, namely the Greater London
Urban Area and Gibraltar, have exceeded the limits for PM10.
This is the latest in a series of legal actions taken by the Commission
against Member States following the entry into force in June 2008 of the new EU
Air Quality Directive. The Directive allows Member States to request, under
certain conditions and for specific parts of the country, limited extra time to
meet the PM10 standards which have been in force since 2005.
First warning letters were sent at the beginning of 2009 to Member States
that had not by then submitted notifications for time extensions or had not
notified the Commission about all air quality zones exceeding the limit values
for PM10. As a result, most Member States involved submitted notifications for
a time extension.
The UK submitted an exemption request for eight zones including the Greater
London Urban Area. However, the Commission did not consider the exemption
justified, as seven out of the eight zones already complied with the limit
values. For the Greater London Urban Area, the Commission considered that the
UK had not shown that compliance with the daily PM10 limit value would be
achieved by the time the exemption period expired in 2011. The UK has recently
sent a further exemption request for Greater London, which is still under
assessment. However, given that zones still exceed the PM10 limit values, the
Commission is sending the UK a final warning. If the UK fails to take the
necessary measures to comply with the legislation, the Commission could refer
the case to the European Court of Justice.
Air quality legislation
EU air quality legislation sets binding limit values and/or indicative
target values for the maximum permitted concentrations of certain pollutants in
the air. Action to reduce pollution through an air quality plan is required
where there is a risk of these standards being exceeded.
Limit values for PM10 impose both an annual average concentration value of
40 micrograms (μg)/m3, and a daily concentration value of 50 μg/m3 which must
not be exceeded more than 35 times per calendar year. These entered into force
on 1 January 2005.
The 2008 Air Quality Directive allows Member States, under strict
conditions, time extensions for meeting the air quality standards for PM10
(until 11 June 2011) and NO2 and benzene (until 2015 at the latest). During the
extension period, limit values continue to apply plus a margin of
