How environmentalists hope to toughen clean-air and fuel-efficiency laws:

-- Win over California, the only state that can adopt its own clean-air standards

-- Take California proposals to the Northeast, where legislators have tackled clean-air issues

-- Move deep into the heartland, so auto makers can't ship cleaner cars to just the two coasts

-- If enough states enact the California standards, pressure Washington to adopt them nationally
