London plans to meet WHO air quality target by 2030

Mayor of London Sadiq Khan has promised that the capital will comply with the World Health Organization’s guideline limit and backed a ‘Global Green New Deal’ on climate change.

The pledge to reduce fine particulate (PM2.5) concentrations to 10 micrograms per cubic metre was made at the C40 World Mayors Summit in Copenhagen on Friday. Leaders of cities such as Washington DC, Berlin, Rotterdam and the notoriously polluted Mexico City, alongside Copenhagen itself, also signed the Clean Air Cities Declaration.

Progress will be publicly reported, the intention being to produce a ‘race to the top’ for cleaner air. Full compliance by the group would avoid around 40,000 early deaths each year.
