greenhouse emissions; regulations; fuel economy

Our Position: oppose
Bill Number: SB1147
Sponsor: S. Allen, Gould, R. Pearce, et al
Legislative Session: 2009 Legislative Session

It requires express legislative authorization in order for any state agency to adopt or enforce a state or regional program to regulate greenhouse gas emissions or motor vehicle fuel economy.  This is a silly bill that will likely have limited impact as most of this will end up being enacted by the federal government, but it will tie the hands of the state on some key issues and generally just sends a bad message.  It will have a negative impact on air quality by sidetracking the Clean Car Standards.


07/03/09 - It was never heard in the House, so died this session.

The Clean Car Standards alone will have enormous air quality benefits and are expected to reduce 5,505 tons of carbon monoxide (CO), 892 tons of hydrocarbons and 1,436 tons of oxides of Nitrogen (NOx) in 2018. Both NOx and hydrocarbons are precursors for ozone formation.  Implementation of the standards will reduce ozone-forming pollution, reversing it will make it even more difficult to meet the health based standard.


Ozone is a problem and at its worst during the hot summer months.  Ozone is formed when sunlight reacts with volatile organic compounds emitted from vehicles, industry, and other sources.  Transportation is the number one contributor to ozone pollution.  Because of the weather patterns, areas in the northeast valley of the Phoenix area such as Fountain Hills suffer most from this pollution.

Ozone damages lung tissue by reacting chemically with it and prematurely aging the lungs. Exposure to ozone increases the risk of asthma attacks and reduces lung function.  It also causes pulmonary inflammation and risk of premature mortality.  Metropolitan Phoenix is one of the top five U.S. cities for asthma-related mortality.

The automobile manufacturers indicate that these standards will make vehicles unaffordable or that people will not be able to get a pick-up truck or other class of vehicle.  That is blatantly untrue.  The California standards allow all models to comply, and the price increases are approximately $300 for the 2012 models and about $1000 for the 2016 models.  The payback periods for this small increase are only about 1.6 years and 2.9 years respectively, making this change very affordable and consumer-friendly.

The Clean Car Standards allow manufacturers plenty of flexibility in meeting these standards, including a combination of reductions in tailpipe emissions of carbon dioxide, nitrous oxide, and methane.  The manufacturers can also get credit for systems that mitigate fugitive emissions of hydroflurocarbons.
