In April 2001, Portland City Council and the Multnomah County Board of Commissioners adopted a joint Local Action Plan on Global Warming with a goal of reducing greenhouse gas emissions to 10 percent below 1990 levels by 2010. Continue reading

Enacted in 1997, the Oregon law requires any new power plant to reduce net carbon dioxide emissions 17 percent below the level of the best existing combustion-turbine plant anywhere in the United States. The standards are periodically updated as more efficient power plants are built in other states. Continue reading

In January 2007, the California Public Utilities Commission (PUC)adopted an interim Greenhouse Gas (GHG) Emissions Performance Standard(EPS) in an effort to help mitigate climate change. The standard is a facility-based emissions standard requiring that all new long-term commitments for baseload generation to serve California consumers be with power plants that have emissions no greater than a combined cycle gas turbine plant.

Californiais the only state empowered under federal law to pass stronger air pollution standards than those set by the federal government. Other states can then choose California’s standards, but cannot be the first to surpass those set by the federal government. Thus, the passage of a California law leading to regulation of greenhouse gas emissions from cars eventually could spark changes in the design of automobiles sold across the country. As of 2009, at least 16 other states had passed legislation adopting California’s "clean cars" standard (pending waiver being granted by the EPA). Continue reading
