Exhaust Emissions

Volume 506: debated on Wednesday 3 March 2010

To ask the Minister of State, Department for Transport what estimate he has made of the total carbon dioxide emissions from trains in the last 10 years; and what projection he has made of such emissions from trains in the next (a) 10, (b) 20 and (c) 50 years. (317025)

Rail carbon dioxide (CO2) emissions for the last 10 years can be found at:

The source of the data is AEA/Department of Energy and Climate Change (DECC).

Projected CO2 (ktonnes) emissions in GB, as published in the Carbon Pathways Analysis document by the Department for Transport, are shown in the following table:

Projected carbon emissions are on a different basis from the historic figures. The former are based on data from the Office of Rail Regulation, while the latter are from the UK’s Greenhouse Gas Inventory.

To ask the Minister of State, Department for Transport what estimate he has made of the total carbon dioxide emissions from (a) domestic and (b) international aviation in the UK in the last 10 years; and what projection he has made of the emissions from (i) domestic and (ii) international aviation in the UK in the next (A) 10, (B) 20 and (C) 50 years. (317026)

Aviation carbon dioxide (CO2) emissions for the last 10 years can be found at:

The source of the data is AEA/Department of Energy and Climate Change (DECC).

The following table shows the Departments latest forecasts for international, domestic and total CO2 emissions from flights departing from UK airports in 10, 20 and 50 years.

Notes:

1. Data are for UK departures only.

2. These forecasts refer to the central demand scenario s12s2, with Stansted R2 in 2015 and Heathrow R3 around 2020, as presented in “UK Air Passenger Demand and CO2 Forecasts”, January 2009.

3. These CO2 forecasts include freight, APU and a residual adjustment to ensure consistency with the DECC outturn estimate.

To ask the Minister of State, Department for Transport what estimate he has made of the total carbon dioxide emissions from road transport in the last 10 years; and what projection he has made of such emissions from road transport in the next (a) 10, (b) 20 and (c) 50 years. (317028)

Road transport carbon dioxide (CO2) emissions for the last 10 years can be found at:

http://www.decc.gov.uk/en/content/cms/statistics/climate_change/gg_emissions/uk_emissions/2008_final/2008_final.aspx

The source of the data is AEA/Department of Energy and Climate Change (DECC).

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:
