here is an interesting article on Eco-Driving - i like Fiat's idea of an onboard computer that saves driving data onto a flash drive, which then is plugged into a laptop to allow users to analyze their driving performances in terms of CO2 emissions.

Auto Makers Ask EU to Support Eco-Driving

PARIS – European auto makers are calling for greater support from national governments and European Union institutions in promoting eco-driving – where good motoring styles are adopted that reduce greenhouse gases and other vehicles emissions.

The EU sees itself as a world leader in the fight against climate change, with some of the toughest legislation on the planet in the fight to cut carbon-dioxide emissions.

However, it has no legislation encouraging drivers to keep steady speeds, avoid sharp accelerations and other behaviors that increase emissions.

European auto makers complain they are shouldering too heavy a burden.

“Reducing CO2 emissions from cars should be a shared responsibility,” says Wolfgang Hennig, eco-driving manager for Ford of Europe’s environmental strategy and communications department. “Technology, alone, cannot solve this question of how to reduce emissions from cars.”

Hennig believes action also should be required from the fuel industry, policy makers and consumers if auto makers must make their cars greener.

“We want to be part of the solution, but there have been no discussions about this with policy makers,” he says.
