Carbon emissions overall in Oxford have reduced by 27% between 2005 and 2014. According to the latest carbon emissions data released by the Department for Energy and Climate Change (DECC), overall emissions in Oxford have fallen from all sources — commercial, domestic, and transport — since 2005.
Whereas domestic and industrial and commercial emissions in Oxford reduced faster than the England average, transportation emissions did not reduce as rapidly. The slower reduction in transportation emissions highlights the need for an improved low carbon transport system, as that is the sector that has seen the least improvement over the last ten years.
