UK air quality in 2050 - synergies with climate change policies

Estimates are made of air quality in the UK around the time of 2050 on the assumption that significant changes are made to energy and transport technologies to move towards the goal of a 60% reduction in carbon emissions by 2050 on a 1990 base. London is used as an example to assess possible future concentrations of particulate matter and oxides of nitrogen. Emission reductions and their effects on ozone concentrations in the southern UK are also discussed. The paper concludes that significant synergies and co-benefits are possible through a concerted consideration of air quality and climate change policies. (C) 2006 Elsevier Ltd. All rights reserved.
