The Government should raise taxes on air travel and high-polluting cars in order to help the environment, an important committee of MPs  has said. It also said that the 70 mph speed limit on motorways should be reduced or enforced to bring down the amount of carbon dioxide given off by cars The House of Common Environmental Audit committee’s latest report said that transport was the only sector（部门）of the UK where carbon emissions have continued to rise since 1990.

It said it was time for the Government to make demand for cheap air impossible by raising air passenger tax. Emissions from air traffic have risen by 5 times as much since 1900 and are continuing to rise.

The committee welcomed the recent introduction of changed car tax, which means that the lowest-carbon cars pay no road tax, while gas-guzzling（耗油的）4×4s pay an increased rate of ￡210. However, the MPs say it doesn’t go far enough and are calling for a top limit of ￡1,800 with lower limit of ￡200.

Committee chairman Tim Yeo said : “Air travel in particular is the fastest growing source of CO₂, with emissions more than five times since 1900. The Government should take much more decisive action to reduce the difference of income favor of trains, buses, and lower carbon cars and lorries.”

Friends of the Earth’s senior organizer Tony Bosworth said: “Emissions from transport are still rising and forecasts suggest they will carry on rising for years to come.”

“Tinkering（随意或部分修补）around the edges is no longer enough to deal with the greatest threat the world faces.” A spokesman for the Department for Transport said: “Dealing with carbon emissions in transport is a key problem.”
