An organisation called 10:10, which pushes for a 10 percent cut in the UK’s carbon emissions during 2010, has proposed a change to the UK’s clocks. It claims would reduce Britain’s CO2 output by hundreds of thousands of tonnes.
A study conducted by Cambridge University for the campaign — called “Lighter Later" — found that putting clocks one extra hour forward in the winter would make evenings lighter and reduce peak electricity demands, saving almost 500,000 tonnes of carbon dioxide. Researchers say that’s the equivalent of removing 200,000 cars from the road.
10:10 say that extending that hour’s change to the summer, making British Summer Time two hours ahead of GMT, would also deliver savings for similar reasons. It may also reduce accidents on the roads in the evenings, making it safer for people to walk home at night, and offer a boost to the leisure industry. 10:10 reckons that boost could be as large as 60-80,000 new jobs, worth an additional £2.5-3.5 billion to the economy.
