Air pollution target

The Times, 18 October 2019:

Sir, The Queen’s Speech promised air quality targets that would be “among the most ambitious in the world”. Unfortunately we have not been told what those targets will be, or the date by which they will be implemented. The Clean Air Bill, published as a private member’s bill last week, includes a commitment to achieve WHO standards by 2030 at the latest.

The most dangerous type of air pollution is small particulates, and the annual WHO limit for PM2.5 is 10 microgrammes per cubic metre of air, which is significantly lower than the average level in central London of 15. The EU limit is 25; in the US it is 12 and in Australia 8.

The government needs to announce a phased reduction in the legal limit for PM2.5 that should stipulate 15 mcg/m3 for 2020, 12 mcg/m3 by 2025 and 10 mcg/m3 by 2030. This would provide the necessary incentive for the government and councils to promote public transport and reduce car usage, particularly in urban areas. In addition it would require the government to speed up the introduction of electric vehicles, and to bring forward the phase-out date for diesel and petrol-driven vehicles to 2030. This date would align with several other European countries, including Denmark and Sweden. Moreover, it would help the UK to meet its climate change commitments which, as things stand, are almost certain to be missed.
