LONDONERS are being asked to come up with their own ideas to help tackle climate change.

Designer Vivienne Westwood, impressionist Rory Bremner and actress Jane Horrocks are among the famous faces to back the scheme.

Residents can log on to a website, upload their ideas, give their opinions and vote on other proposals.

Some early ideas include sharing taxis to save fuel and emissions, cutting down on the amount of printed paper you use and buying a water meter.

The best ideas will be incorporated into Mayor of London Boris Johnson’s climate action plans.
