Switch off instead.
Now we all know that CO2 is a harmful component of exhaust gases. It is important for its contribution to global warming, but exhaust fumes also contain other chemicals and particulates, which long term exposure to has been linked with cancer, asthma and other respiratory diseases.
According to the http://switchoffandbreathe.org/ website air pollution, caused by transportation, accounts for up to 40,000 deaths within the UK each year, a figure 10 times higher than the annual number of traffic fatalities.
So what are the authorities doing about it? The East Central Scotland Vehicle Emissions Partnership was created far back in 2004 to help improve air quality across Scotland. It works in conjunction with the Scottish Government, East Lothian, Midlothian, West Lothian and Falkirk Councils, to encourage road users to improve their environment by providing free educational events within east central Scotland.
