Easy Kyoto drive

This article reports that doubling the fuel efficiency of every car in the U.S. would cut the country's huge carbon emissions by 10 per cent— enough to meet its target under the Kyoto protocol, should it ever sign up. The key, say Rob Jackson and William Schlesinger from Duke University in North Carolina, is to persuade drivers to replace their cars with hybrid electric vehicles. While the average car on U.S. roads in 2001 had an efficiency of g kilometers per liter and new cars 12 km/1, HEVs can run at over 20 km/1 by using an electric engine to supplement the conventional internal combustion engine. The pair argue that this goal is achievable because it doesn't require a major change in lifestyle. The first Ford model T cars achieved 9 kilometers to the liter, Jackson points out.
