Liftshare
The website Liftshare estimates that a typical carsharer will save themselves around £1,000 and 1 tonne of CO2 per year by sharing their daily journey.
National Liftshare day is 14th June, so please pass on the message and try to get everyone to share on that day, and perhaps set a pattern for the future.
