Denox denial

'50 most polluted roads in the UK' report, ITV, 24 Feb 2014

London has some of the poorest air quality in Great Britain

London has the highest nitrogen dioxide levels in Europe, ITV London reported (24 Feb 2014).

London has the highest levels of NO2 of any European capital city and the UK has the highest proportion of zones breaching legal limits.

The need to denox transport in cities has been neglected, not only by Transport for London, but also authorities such as Centro, and Transport for Greater Manchester. Cancellation of the HS2 project would liberate resources to clean up public transport in the metropolitan areas. Electrification of road public transport in Birmingham has previously been discussed on the Beleben blog.

  1. Advanced petrol engines may become as fuel efficient as diesels. If so the particulate and Nox problem may vanish. In any event the belief that electric cars emit less carbon than the competing IC vehicle is based on the Arup Cenex roport of Ocober 2008. It depended on the wild claims of manufactures and ignored the very large carbon emission associated with battery manufacture.

    In contrast we have an analysis, based on fundamentals, which is void of such weaknesses. That analysis shows that the electric car, far from being green, may very well emit more carbon than its IC competitor.

    • In the view of the Beleben blog air quality, and greenhouse gas emissions, are separate issues. The need for denoxing seems to have been neglected. As can be seen in The problem of second worst, diesel vehicles can be a significant problem for air quality in cities.
