In 1997, 37 major economies formally committed to cutting emissions.
Under European rules, this funding can only be used to lower emissions during vehicle production and in consumer use.
The reasons for this difference came down to price pressures of the American market, and tighter emissions regulations.
The Commission does not regulate exposure to emissions from these devices.
This is equivalent to a change to emissions to between 5% above and 1.8% below 1990 levels by 2020.
Transportation remains the second largest contributor to emissions, about 27 percent.
There is clearly an urgent need for action here, and the car industry must make its contribution to cutting emissions.
And they also have the highest figure when it comes to emissions per head of population, over 10 times more than most developing countries.
It is whether government policy should say anything at all about fuel economy, as opposed to emissions.
Meeting the basic energy needs of all the world's people would contribute less than 2% to current global emissions.
