“The supreme court has ordered the government to make plans for tackling the UK’s air pollution problem, which has been in breach of EU limits for years and is linked to thousands of premature deaths each year.
London and several other British cities have failed to meet EU standards on nitrogen dioxide (NO2) levels since 2010, running the risk of fines from Brussels and prompting a legal challenge by NGO ClientEarth.”
