The Government has not made any cost-benefit analysis of the impact of HS2 on carbon monoxide emissions.

The HS2 Economic Case quantifies the impact of HS2 on non-traded direct Greenhouse Gas emissions (which include carbon dioxide, methane and nitrous oxide) resulting from changes in petrol/diesel use from road and rail passenger transport as a result of HS2. This analysis estimates that the full HS2 Y-Network generates benefits of £101 million (2011 prices, NPV) from reduced non-traded Greenhouse Gas emissions.
