The UN Environment Programme has just published its "Kick the CO2 habit" guide to beating greenhouse gasses as an individual.
Suggested methods include shutting down your computer at lunchtimes, jogging in the park rather than using a treadmill and drying clothes on a washing line rather than in a tumble dryer.
What many Brits may not realise is that they can be eco-warriors in their gardens too.
