Green car hire2

When hiring a car anywhere abroad, book with Avis, who have a series of eco-friendly cars from ones that run on natural gas to some that even run on alcohol.

Hire a Honda Civic hybrid gas-electric car for a weekend in Portugal for £40 or a Saab biofuel ethanol-powered vehicle in Sweden for £83.

When you book your car, Avis will give you the opportunity to offset your carbon footprint for a small fee, starting from £1. For every car in its rental fleet, Avis plants a tree in forests throughout the UK.

Alternatively, Hertz does a Green Collection range of environmentally friendly, fuel-efficient vehicles. Meeting the 2008 voluntary target set by the EU for the European Automobile Manufacturers Association, they pump out on average less than 140g of carbon dioxide per kilometer. As a sample price, the dual-fuel hybrid Toyota Prius can be hired for £48 for a weekend in France.
