Monday 29 May marks the start of green week, and the European Commission launches a new initiative, 'You Control Climate Change' to coincide. The scheme aims to raise the awareness of climate change in Europe, by reaching out to EU citizens and publicising ways of limiting environmental impact. The message is clear - to minimise environmental impact, small changes need to be made by a large number of people to make a lasting difference. For example, to turn lights off, to install energy efficient light bulbs, to turn television sets off, rather than leave them on stand-by. This message is reflected in the campaign slogan - Turn Down. Switch Off. Recycle. Walk. Green Week this year will have a strong focus on preserving biodiversity in Europe, with a series of conferences throughout the week tackling this issue. Meanwhile, we can all devote a little time to thinking about how we can help control climate change. Belgian Prime Minister Guy Verhofstadt and EU Commissioner for the Environment, Stavros Dimas will launch the campaign later on Monday 29 May at the famous Mannekin Pis statue in Brussels. Prime Minister Verhofstadt and Commissioner Dimas will later be joined by European Commission President José Manuel Barroso and the Belgian Minister for the Environment, Bruno Tobback at the Berlaymont to roll-out the European launch. In Europe today, households are responsible for 16 per cent of the EU's greenhouse gas emissions. 70 per cent of household energy is spent on heating homes, 14 per cent on heating water and 12 per cent on lighting and electric appliances. Private cars use another 10 per cent of EU greenhouse gas emissions. The campaign will provide more than 50 tips on how we can reduce emissions without compromising our quality of life.
