I just came across this article about Avis on AutoblogGreen, which has posts about greener driving and new car technology. It discusses some research and cost comparisons we commissioned recently on how people can reduce their driving expenses – and carbon emissions – by downsizing the car they own, or using public transport instead, and then renting when they need a larger car, such as for holidays or weekend breaks. The research shows some pretty hefty savings!

It makes sense, when you think about it. In fact, drivers have already been doing this in Australia, because of higher oil prices (and fuel isn’t exactly cheap here either!). In the UK, another spur could be proposed ‘green taxes’ such as the emissions-based parking charges that the borough of Richmond in south-west London approved recently.

I’ve started car-sharing with a colleague whenever possible, so I’m beginning to see the savings first hand. Every little helps!

If you have downsized your car then let us know if you’ve been seeing the savings. And feel free to post any other ideas on how to cut the cost of transport.
