Arizona proposes greenhouse gas emission rule that targets cars

| 11/28/2007

Arizona moved forward with its pledge to join California in cutting greenhouse gas emissions.

The Copper State is likely to avoid imposing new regs for trucks, however.

Arizona’s Department of Environmental Quality will formally introduce a new proposed regulation to limit greenhouse gas emissions that closely follows a 2005 law from California, according to a news release from the department. A public comment period would follow, and the law could be approved by spring 2008.

Greenhouse gas emissions increased by 56 percent from 1990 to 2005, which the agency said is the fastest growth rate in the nation.

“If unchecked, Arizona’s GHG emissions are projected to grow by 140 percent between 1990 and 2020 and by 200 percent between 1990 and 2040,” the news release stated.

Trucks probably won’t be included in the new greenhouse gas emissions standards, one agency employee told Land Line on Wednesday, Nov. 28.

“The rules haven’t been written, but everything’s being targeted to passenger vehicles,” said Mark Shaffer, a spokesman for the Arizona Department of Environmental Quality. “Our department is working on the rules package on this. The focus has been on passenger vehicles.”

In addition to California, the 11 other states that have adopted California’s greenhouse gas vehicle standards are Connecticut, Maine, Maryland, Massachusetts, New York, New Jersey, Oregon, Pennsylvania, Rhode Island, Vermont and Washington. Colorado, Florida, New Mexico and Utah have said they also will adopt the California plan.
