Give us your most serious face Friends of the Earth has launched an innovative flash website for its Get Serious About CO2 campaign. www.getseriousaboutco2.com If you haven't done so already, upload your most serious face to show how serious you are about local action to cut CO2. Have fun on the site by organising into tribes based on how serious you are on topics from CO2 to Sudoku. We'll use the photos to call for more money and less hassle for councils to make the serious cuts needed to save our climate. Show you're serious about councils cutting CO2 .
