How to win the war on air pollution


The Guardian, 19 February 2017:

Air pollution is not just a London problem (Editorial, 17 February). Of the 43 zones currently monitored in the UK, 38 fail EU standards for NO2, so any strategy has to be nationwide and not left to individual councils.

The most likely government response is an extension of clean air zones, but there are serious doubts as to whether this will improve public health. First, designating certain areas as clean does nothing to reduce total emissions; it merely diverts them elsewhere. Second, the health effects of NO2 and particulates are without threshold, so reducing levels below an arbitrary limit may make sense politically, but will have little effect biologically. Third, the projected improvement in air quality is predicated upon new vehicles producing less NO2 in line with stricter EU vehicle emission tests, but we already know that emissions of NO2 “on the road” are four to five times greater than in laboratory tests, a discrepancy that even applies to the latest Euro 6 engines. Finally, studies of London schoolchildren showed no improvement in lung function after three years living in a low-emission zone.

As your leader proposes, we are in urgent need of a new Clean Air Act that hastens the demise of diesel and other highly polluting technologies, something the government could and should have championed more than 20 years ago.

Finding a solution to pollution

sunday times

Sunday Times, 5 February 2017:

Most of the carnage inflicted by Trump since he took office can be reversed when he leaves; the exception is climate change, since failure to mitigate global warming today will probably result in irreversible changes tomorrow. Trump’s solution is to ban any discussion of global warming when he meets the royal family, even though the future of humanity is under threat. He needs to recognise that there is not a single reputable scientific journal, or a single national scientific institute, that does not accept that global warming is man-made and getting worse. His behaviour is that of an autocrat in denial.
