Climate Cars are a new fleet of eco-friendly taxis in London. They drive hybrid cars and offset their emissions using The Carbon Neutral Company. What is interesting about Climate Cars is their Bike Rescue service. All of their cars carry bike racks. So if your eco-friendly self chose to ride a bike to work but then later questioned your commitment to climate change when it started pouring rain at the end of the day, you can still get a ride home from Climate Cars (complete with bike and a guilt-free conscious).
