California has taken legislative steps towards reducing the possible effects of climate change by incentives and plans for clean cars, renewable energy, and stringent caps on big polluting industries.
Development of the Scoping Plan is a central requirement of AB 32, that calls on California to reduce its greenhouse gas emissions to 1990 levels by 2020.
The comprehensive approach includes both new and existing measures in every sector of California's economy.
It includes a series of proposals that would become law in 2012, with some measures going into effect two years earlier. The initiatives include implementing a cap-and-trade program on carbon dioxide emissions (that will be developed in conjunction with the Western Climate Initiative, to create a regional carbon market) that will require buildings and appliances to use less energy, oil companies to make cleaner fuels, and utilities to provide a third of their energy from renewable sources like wind, solar and geothermal power and proposes to expand and strengthen existing energy efficiency programs. The Plan will also encourage development of walkable cities with shorter commutes, high-speed rail as an alternative to air travel, and will require more hybrid vehicles to move goods and people, following the implementation of the California Clean Car law (the Pavley standards).
Several additional initiatives and measures play important roles in reaching the required reductions under AB 32. These include:
California has enacted climate change legislation & executive orders:
States with similar limits are: New York, Massachusetts, Connecticut, Vermont, Rhode Island, Maine, and New Jersey.
