Energy and Emissions

This section allows you to explore data on transport-related air pollution emissions (such as carbon monoxide, nitrogen oxides, hydrocarbons or VOCs (volatile organic compounds), particulates, sulphur dioxide and lead), greenhouse gas emissions (such as carbon dioxide, methane, and nitrous oxide) and energy consumption by transport (million tonnes of oil equivalent), along with forecasts to 2030. For the full database set of countries, historic data on emission of oxides of nitrogen and particulates are listed where they are available. Detailed national emission data are available for the UK, France and USA, covering a wider range of pollutants.

To find out more about how data in this section have been compiled, the definitions used and associated caveats go to the Energy and Emissions section of the Data Definitions and Caveats page.

The amount of oil used as the energy source for road transport is growing in almost all countries, despite improvements in the fuel efficiency of individual vehicles.

The emission of carbon dioxide (CO2) from road transport is forecast to rise in all countries, and particularly China, which could overtake Japan by 2015.
