'Drive at 70mph and save the environment'

The Commission for Integrated Transport (CFIT) has called for more to be done to cut carbon emissions from road vehicles, including installing gearshift indicators on dashboards to encourage drivers to use their gears properly and making drivers stick to a 70mph speed limit, generating 30 per cent less CO2 than at 80mph.The commission also said that emissions could be cut if air conditioning was used less and if roof racks were removed. It suggested that drivers could benefit from lessons in eco-motoring. Going easy on the accelerator and not breaking too heavily could make a significant difference. The CFIT called for all cars to produce no more than 100g of CO2 per kilometre by 2020 and wants the government to make flying more expensive. The committee said that its proposed measures would increase by 70 per cent the CO2 savings proposed by the government's climate change programme, ie rather than stabilise carbon emissions by 2020, they would actually be reduced by 14 per cent. • Research by the Liberal Democrats has shown that the government may talk tough on the environment but green taxes have actually gone down in recent years. Fuel duty, landfill tax, hydrocarbon duty, air passenger duty and others took 2.7 per cent of national income in 2006 compared with a peak of 3.6 per cent in 1999. The Lib Dem Shadow Environment Secretary Chris Huhne said: “Mr Brown has cut green taxes by a fifth even though they are crucial to changing our behaviour. He has cut flood defence and climate research budgets. He vetoed the plan to toll road freight, and he ditched the legal requirements on big companies to report their environmental impact in operating and financial reviews.”• The Lib Dems are the greenest party, according to the Green Standard report by such environmental groups as Greenpeace, Friends of the Earth, WWF, the RSPB and the Campaign to Protect Rural England. The Lib Dems got three "green lights" in the report while Labour and the Tories didn't get any.
