The road ahead for Clean Cars
In 2005, the state Legislature passed a Clean Cars measure to reduce tailpipe emissions 30 percent by 2016, starting in 2009. The standard follows a California law passed in 2002, and will cover automobile pollution that causes smog, as well as carbon dioxide (the primary form of global warming pollution).
These tailpipe standards, now law in 12 states, cannot go into effect without permission from the Environmental Protection Agency. EPA is now considering California’s request.
The U.S. Supreme Court recently ruled that the EPA must regulate global warming pollution from automobiles. However, the Bush Administration has indicated that it wants to hold off until the end of 2008, when Bush will be on his way out of office. If the EPA does not grant the state’s application by October,
Gov. Arnold Schwarzenegger has promised to sue the federal government. Many of the other Clean Car states are likely to join the suit.

Hybrid cars address the problem of high gas prices and global warming.
