I choose not to own a car and usually get about on public transport. I know all about car pooling and ride sharing and I'm familiar with companies like Streetcar and WhizzGo, which hire cars by the hour. But these are not an option for longer rentals.
So is it possible to rent an "eco car" under a standard rental agreement, that doesn't end up costing a fortune?
My question then is why aren't all car hire companies committed to greening their fleet? And what can be done to encourage them to do it?
