Do you want to live a more low-carbon lifestyle, but are unsure where to start?

Tread lightly is the Guardian's new green community of people committed to reducing their CO2 emissions. By making weekly pledges and recording your actions, you can see how much carbon you have saved individually, and as a community.

Each Friday, there will be a new pledge to sign up to. These will range from simple actions such as the first week's pledge of switching to energy efficient light bulbs, to taking showers instead of baths and turning appliances off standby, as well as more imaginative ideas that you can suggest.
