8 states vow 3.3M zero-emission vehicles by 2025

SAN FRANCISCO Automakers are applauding a pledge Thursday by the governors of eight states, to work together to help make the highways more friendly for zero-emission vehicles.

The goal is to create charging stations and other fueling infrastructure that would get 3.3 million of the vehicles on the roads by 2025, to curb greenhouse gas pollution.

Representatives from the eight states gathered in Sacramento, Calif., to sign an agreement creating a task force that would help bring about those changes.

By doing so, state officials hope to boost the market for electric cars, hydrogen fuel-cell electric vehicles and plug-in hybrids.

In addition to California and New York, the states involved are Massachusetts, Maryland, Oregon, Connecticut, Rhode Island and Vermont.

Car companies say it's an important step toward getting consumers interested in the technologies.

Until now, they've been slow to catch on because of worries about electric car range.

Dan Gage of the Alliance of Automobile Manufacturers says the goal of 3.3 million vehicles isn't currently achievable — because without the necessary infrastructure, there isn't enough consumer interest.

The eight states together represent about 23 percent of the U.S. auto market.

Each state has already, separately adopted rules to require a percentage of new vehicles sold to be zero emission by 2025.

California's mandate of 15.4 percent calls for a total of 1.5 million zero-emission vehicles to be on the state's roads by that time.

While the agreement signed Thursday requires no specific financial commitment from each state, they have all vowed to work together to smooth building codes and other regulations in a way that will allow quick rollout of new charging stations.

"The idea is to make it easier for customers to operate and use zero emission vehicles, this in turn will help pave the way for success of the auto industry," Mary Nichols, chairman of the California Air Resources Board, said.

Deb Markowitz, Vermont's natural resources secretary, said her state has not put a cost on achieving the goals, but believes in the end the state will partner with private companies to help them build charging stations and other infrastructure needed.

Getting 3.3 million of these vehicles will be a steep curve.

In California, plug-in-hybrids and electric vehicles currently make up less than 2 percent of the auto market.

There are now 16 zero-emission vehicles from eight manufacturers on the market; nine that run on batteries alone, two hydrogen fuel cell cars and five plug-in hybrid models, which can run on battery alone or gasoline.

Officials say that every automaker will have a zero-emission model by 2015.

Car dealers, who are under pressure to help meet these 2025 goals, say getting fueling infrastructure like charging stations in place quickly is the only way to get average consumers used to a new product that requires new driving habits.

"We think that is going to be necessary for some of the range anxiety and other acceptance barriers that need to be broken down," said Brian Maas, president of the California New Car Dealers Association.

"The cars are coming — they're here already — but if you don't have a place to charge them, there's not going to be the level of consumer acceptance."

Governors signing the memorandum all hailed the cooperative effort as a way to more quickly solve the inevitable problems that arise when making such far-reaching changes in people's everyday lives.

And some see future economic benefits from the switch to new vehicles.

Massachusetts Gov. Deval Patrick said more electric vehicles are key to his state's efforts grow the region's economy.

"Diversifying transportation fuels and providing drivers with options will help reduce vulnerability to price swings in imported oil that hurt consumers and our economy," Patrick said in a statement.
