Summary: Global Warming Impacts on California (PDF)
A one-page summary of the ways in which global warming is expected to impact California--based on the latest science from the state's February 2006 Climate Action Team report (which includes 18 new papers by more than 30 researchers at the state's top universities and research institutions)

Consumer Benefits of the California Global Warming Law (PDF)
The increased price of vehicles that comply with California’s vehicle global warming regulation will be more than offset by reductions in vehicle operating costs. In fact, many of the likely new technologies used to meet the requirement will "pay for themselves" in less than five years, the length of an average auto loan.

Climate Control: Global Warming Solutions for California Cars
Because California accounts for more than 10 percent of all new vehicles sold in the United States, reducing emissions of heat-trapping gases here will have a noticeable effect on the national inventory. Furthermore, the way in which the state regulates its motor vehicles also has a powerful influence on the rest of the nation. Modeling conducted by the Union of Concerned Scientists shows that by applying currently available technology to all new vehicles sold in California, fleet average heat-trapping emissions could be reduced 20 percent. The additional cost of these vehicle improvements would be recouped in the form of decreased operating costs after less than three and a half years of driving, on average.

Vehicle Safety and the California Global Warming Law (PDF)
California’s vehicle global warming regulation will result in large environmental benefits, without any negative effects on vehicle size, weight, or safety. In fact, the technology already exists to reach California’s goals while maintaining safety and a wide variety of vehicle choices, without changing vehicle weight. Even more technology is available to save lives on California’s highways, but automakers are crying wolf instead of providing consumers safe vehicle choices today.

What Are global Climate Models? (PDF)
General Circulation Models, sometimes referred to as Global Climate Models, are based on the fundamental laws of nature that govern the earth-atmosphere-ocean system and are constantly being updated to reflect the very latest observations and scientific understanding.  This fact sheet explains how the climate models work, what the strengths and uncertainties of the models are, and how the climate projections for different models compare.  The bottom line is that all models, despite some variances, predict significant increases in temperature toward the end of century due to increased concentrations of man-made heat-trapping gases.

Upcoming California Diesel Regulations (PDF)
As part of California's Diesel Risk Reduction Plan, the state has several important regulations coming up over the next two years.  This fact sheet explains what the regulations are and when they'll be coming before the California Air Resources Board for a vote.

Digging up Trouble: Construction Pollution in California (PDF)Pollution from diesel construction equipment is taking a heavy toll on the health and economic well-being of California residents. This equipment contributes to particulate and ozone pollution that can cause severe cardiovascular and respiratory illnesses, asthma attacks, acute bronchitis, and even premature death.

Diesel Idling in California (PDF)
This fact sheet explains the benefits of a new California Air Resources Board regulation that limits idling to five minutes for diesel trucks with sleeper cabs--trucks that typically idle all night long.  These changes are expected save over 100 million gallons of diesel fuel and prevent more than 700,000 tons of global warming emissions and thousands of tons of toxic and smog-forming air pollution from being emitted every year.

Clean Construction Equipment for California: A Blueprint for Healthier Communities (PDF)
The construction sector is the single largest source of diesel particulate matter air pollution in the state. This brochure explains construction-related pollution's impact on health, documents the state's efforts to date to clean up this pollution source, and makes recommendations for a quicker and more thorough clean-up.

Sick of Soot: Reducing the Health Impacts of Diesel Pollution in California 
Details ways to cost-effectively reduce the significant health impacts of diesel pollution in California. Diesel soot, or particulate matter (PM), is a dangerous pollutant that can penetrate deep into the lungs. California, with the largest population of people and diesel vehicles in the country, is in essence a microcosm of the national health risks of diesel emissions.

Sick of Soot in the South Coast Air Basin  (Spanish version) (PDF)
Details the impact of diesel pollution on the LA-area. For instance, more than 1,400 premature deaths and about 1,275 cases of chronic bronchitis occur in the LA area due to exposure to diesel pollution. The societal cost associated with all of the diesel-related health incidences is overwhelming, estimated at $10 billion.

California Air Resources Board Diesel Particulate Matter Regulations, 2000-2005 (PDF)
The California Air Resources Board (CARB) has passed numerous rules and regulations since 2000 in an effort to reduce the public's exposure to harmful diesel pollution.  This Fact Sheet summarizes and explains the regulations, and includes links to the corresponding regulatory websites.

33% Renewable Electricity Standard: Renewable Energy for California's Future (PDF)
Raising California's Renewable Electricity Standard from 20 percent by 2010 to 33 percent by 2020 would reduce air pollution, create jobs, and help California reach its commitment to reduce global warming pollution 30 percent by 2020.

fact sheet
California Renewable Energy Standard (PDF)
California’s 2002 Renewable Electricity Standard (RES), required the regulated electric utilities and competitive suppliers to increase their use of wind, solar and other renewable electricity sources by at least one percent per year of retail electricity sales, reaching at least 20 percent by 2017. SB 107, explained in this 2005 fact sheet, accelerated the 20 percent renewables requirement to 2010.

Clearing the Air in the San Joaquin Valley 
The San Joaquin Valley now officially shares the distinction of having the worst air quality in the nation with the Los Angeles region. Without further action, the problem will only get worse.  The population of the region is growing more rapidly than in any other air basin in the state, brings with it increases in vehicle miles traveled and urbanization, both of which counteract progress in emission reductions. This report details the sources of the problem, and offers a set of local, regional, and state policy solutions.
