There is more to being green than driving a Prius and buying local produce. Duncan Clark sheds further light on the eco-friendly messages we've come to take for granted
1. What they tell you: Turning off the lights saves CO2What they don't tell you: It makes sense for individuals to use less electricity to help reduce the emissions of British power stations. However, it's worth bearing in mind that the total amount of CO2 that can be released by power plants and other industrial facilities across the EU between now and 2012 is fixed by the European Emissions Trading Scheme. This means that if the UK power sector reduces its emissions, extra carbon permits get freed up for use elsewhere, such as German power stations or French cement plants. In other words, the same amount of CO2 will be released, just from different sources. If you want to ensure that your electricity savings do make a real environmental difference, join Sandbag, a charity that will remove CO2 permits from the EU scheme to stop your good work being traded away on the carbon markets.
2. What they tell you: Buy a greener carWhat they don't tell you: If you definitely need a new car, it makes perfect sense to buy a small, super-efficient model with low CO2 emissions. However, making a new car – including mining and processing the metals and manufacturing and assembling the components – takes a huge amount of energy. According to an expert at the Stockholm Environment Institute, the production of a typical modern car causes around 8 tonnes of CO2, equivalent to driving 23,000 miles. Because of this, unless you currently drive a lot in a highly inefficient car, it will
