With the blessing of Governor Jerry Brown, a California legislator plans to increase pressure on carmakers to produce zero emissions vehicles.

Assemblywoman Autumn Burke, D-Los Angeles, said today she s going to present legislation next week to require that 15 percent of all new cars be emission-free within 10 years, according to the Associated Press.

Carmakers that don t hit the mandated level would pay fines to the state or make payments to competitors.

If we create more competition in the market, that automatically will trigger a more affordable vehicle, said Burke.

California s current law calls for vehicle manufacturers to gradually increase cleaner technology.

Automakers have annual targets and get credits for hitting them.
