Here is a lovely video in which she explains the current 10:10 lighter later campaign. The campaign is lobbying the government to switch to GMT+1 in the winter, literally making it ‘lighter, later’. This has several large benefits including reduced road accidents, but the main ones that 10:10 are promoting are the large reduction in energy use and therefore carbon dioxide emissions that would ensue.
10:10 cannot reach its potential without kind donations. I have recently donated and also ordered a 10:10 (made of recycled jet plane) to spread the word, which arrived in the post yesterday- very easy to do and a fabulous way to help.
