Pollution and CO2 Consequences
In the EU, the share of transport in CO2
emissions was 21% in 1990, but by 2006 this had grown to 28%. Although somewhat out of date the illustration below is a good proxy for global automotive pollution concentrations.

With over 500m of the 800m cars on the road between them, the USA and Europe will remain the dominant car markets, however considering growth forecasts, pollution pressures and diversified global supply chains, China and India are the key markets for new developments in powertrain technologies.
The Intergovernmental Panel on Climate Change has recommended that Annex I countries reduce their GHG emissions 25-40% by 2020 compared to 1990 and 50-80% by 2050, in order to limit GHG emissions to 450 ppm and the increase in global temperatures to less than 2º C above pre-industrial levels. Appendix 2 of the ‘EU Transport GHG: Routes to 2050?’ report ‘Identifying transport’s potential contributions to future GHG reduction’ TNO, 2009, shows that road transport emissions in the EU-27 need to reduce to 321Mt in 2050 (an approximate share of 16% compared to a 19.5% share of 982 Mt in 2007 - See: http://www.eea.europa.eu/data-and-maps/figures/greenhouse-gas-emissions-in-the-eu27-by-gas-and-sector-2007.
