The government cannot achieve the air quality improvements advised by medical experts, so has set its targets lower for the next 10 years, the environment secretary has admitted as she unveiled a new environmental plan.
Thérèse Coffey said on Tuesday: “We have cleaner air. I want it to be even cleaner. Now, I would have loved to have made our target to achieve 10 micrograms [of fine particulate matter, known as PM2.5, per cubic metre of air] by 2030, not 2040. Many parts of the country already enjoy this, but the evidence shows us that with the best will in the world we cannot achieve that everywhere by the end of the decade, particularly in London.”
