The new carbon-neutral London taxi service has a fleet of Toyota Prius petro-electric cars to provide “karmic” rides around town. Taking cash and account bookings, it costs less than many rival cab firms, which is surprising considering how remarkably posh it is.

All vehicles have sat-nav systems, leather seats, mini fridges stocked with complimentary Belu water, glossy magazines and newspapers. Drivers are smartly dressed and will always open the door for you. Cyclists who lose the will to pedal may order a Climatecar to drive them — and their bikes — home.

Next time you need a ride, perhaps you should consider Climatecars. It’s so much greener than booking a whopping petrol-guzzling family space bus for one measly mortal.
