And we ought to congratulate MetroLink, too, for making it so easy for community members to leave their cars at home. Now, this collaborative approach to energy savings is the same one we're also trying to take with the commercial sector. Remember, residential and commercial together are about a third of our greenhouse gas emissions. We're working with the owners and the managers of the Empire State Building and the World Trade Center in New York, the Sears Tower in Chicago, and many other buildings to cut their energy use by up to 30 percent. It's the approach we're taking in the car industry.
Transportation is a third of the problem.
We've already worked with Ford, GM, and Chrysler for five years now to help them produce prototypes that will get more than twice the mileage of today's cars, with no sacrifice in comfort, safety, or performance. And we are on the verge of having energy engine technologies in transportation that will reduce greenhouse gas emissions by 75 to 80 percent. This is the approach that I'm trying to take to this problem in a comprehensive fashion. Some of the incentives I've proposed, such as tax credits for energy-efficient homes or the solar panels you see there that are so dramatically different from the huge contraptions that used to be necessary to put on roofs, are designed specifically to promote the goals of PATH , the ones I've just announced to you. Today I hope again I can ask all of you to ask the members of Congress who are here with Brad Sherman and don't agree with Howard Berman and Brad to actually vote for this.
