Emissions-producing diesel trucks and cars pass non-polluting windmills along the Intersate 10 freeway.
The Environmental Protection Agency issued a waiver of its rules Thursday that allows California's Advanced Clean Car program to go forward.
The decision will allow California's Air Resources Board to implement a program that: "combines the control of smog, soot and global warming gases and requirements for greater numbers of zero-emission vehicles into a single package of standards called Advanced Clean Cars."
"Today’s waiver from the EPA also allows other states to adopt California’s program. When fully implemented in the states that have signaled they want to adopt California’s policies, about 40 percent of cars sold in the United States will meet the California Clean Cars Program’s strong standards."
The campaign's co-chair is Los Angeles City Controller Wendy Greuel.
