Exhaust Emissions

Volume 508: debated on Monday 22 March 2010

To ask the Minister of State, Department for Transport what estimate he has made of the total carbon dioxide emissions from buses in the last 10 years; and what projection he has made of such emissions from buses in the next (a) 10, (b) 20 and (c) 50 years. (317024)

Bus carbon dioxide (CO2) emissions for the last 10 years can be found in Table 3.7 of Transport Statistics Great Britain (TSGB) at:

The Department for Transport's most recent forecasts of total road transport carbon dioxide emissions for England were produced as part of the road transport forecasts for 2010, 2015, and 2025. These are available in ‘Road Traffic Forecasts 2008: Results from the Department for Transport's National Transport Model', which is available at: forcasts08/rtf08.pdf

The total forecast changes in carbon dioxide emissions for Public Service Vehicles (PSVs), which includes buses and coaches, forecast percentage changes in PSV carbon dioxide emissions in England compared with 2003 for 2010, 2015 and 2025 are provided in the following table:

Carbon dioxide emissions percentage change compared with 2003, England








These figures include an assumption for rising congestion levels, causing slowing vehicle speeds and increasing CO2 emissions as a result.

No such forecasts are available for 2020, 2030, and 2060.
