Highlights of the California Climate Change Program
May 2015 - Under 2 MOU.
California initiated a first-of-its-kind agreement with international leaders from 11 other states and provinces, to limit the increase in global average temperature to below 2 degrees Celsius. Since May, other governments continue to join the MOU. If the signatories represented a single country, it would be the second largest economy in the world behind only the United States.
Governor Brown issued Executive Order B-30-15, which sets a GHG emissions target for 2030 at 40 percent below 1990 levels.
January 2015 - Governor Brown announces five pillars of climate change policy.
In his inaugural address, Governor Brown identified five key climate change “pillars” for obtaining GHG emission reduction by 2030: 50 percent renewable electricity; 50 percent reduction in petroleum use by vehicles; double energy efficiency savings at existing buildings; carbon sequestration in the land base; reduce short-lived climate pollutants.back to top

The Advanced Clean Cars program combined the control of smog-causing pollutants and greenhouse gas emissions into a single coordinated package of requirements for model years 2017 through 2025. Benefits of the Advanced Clean Cars program include: reducing operating and fuel costs, reducing smog by 75%, reducing greenhouse gas emissions by 34%, introducing next-generation cars such as zero-emission and plug-in hybrid vehicles, and creating jobs.back to top
December 1, 2011 - Climate Change Handbook for Regional Water Planning Released
Developed cooperatively by DWR, The U.S. Environmental Protection Agency, Resources Legacy Fund, and The U.S. Army Corps of Engineers, the Climate Change Handbook for Regional Water Planning provides a framework for considering climate change in water management planning. Key decision considerations, resources, tools, and decision options are presented that will guide resource managers and planners as they develop means of adapting their programs to a changing climate. The handbook uses DWR's Integrated Regional Water Management (IRWM) planning framework as a model into which analysis of climate change impacts and planning for adaptation and mitigation can be integrated.
October 20, 2011 - Air Resources Board adopts the final Cap and Trade Regulation
Air Resources Board adopts a key element of the state's pioneering climate plan, Assembly Bill 32 (AB 32) California Global Warming Solutions Act of 2006. The cap-and trade program will now join a suite of other major measures as required under AB 32 to reach the equivalent of the 1990 level of greenhouse emissions by 2020. The regulation sets a statewide limit on sources responsible for 85 percent of California's greenhouse gas emissions and establishes a price signal needed to drive long-term investment in cleaner fuels and more efficient use of energy. The program is designed to provide covered entities the flexibility to seek out and implement the lowest-cost options to reduce emissions. Cap-and-trade will work with other climate programs to drive innovation and jobs and promote efficiency and clean energy. Also, it complements and supports California's existing efforts to reduce smog-forming and toxic air pollutants and improve energy efficiency in homes and businesses.
President Obama announced the next phase in the Administration's program to increase fuel efficiency and reduce greenhouse gas pollution for all new cars and trucks sold in the United States. These new standards will cover cars and light trucks for Model Years 2017-2025, requiring performance equivalent to 54.5 mpg in 2025 while reducing greenhouse gas emissions to 163 grams per mile.

The Education and the Environment Initiative (EEI) was signed into law in 2003 [Assembly Bill 1548 (Pavley, 2003) and AB 1721 (Pavley, 2005)]. It mandated a broad-ranging strategy to bring education about the environment into California's schools, most notably, the development of a K-12th grade, environment-based curriculum. The first-of-its-kind in the nation, the EEI Curriculum is comprised of 85 units, containing hundreds of Science and History-Social Science lessons that emphasize the cause and effect relationship between human actions and natural systems while teaching required academic content to mastery. The EEI Curriculum was developed by Cal/EPA in partnership with the California Department of Education, the Natural Resources Agency, and the State Board of Education, which officially approved the curriculum in 2010. The finalized curriculum began implementation in 2011, and more than 14,000 students received EEI instruction in just the first few months of availability. The ultimate goal is to make the EEI Curriculum accessible to all 6 million students throughout California.

April 17, 2009- Office of Environmental Health Hazard Assessment releases Indicators of Climate Change in California (EPIC) report
Cal/EPA sponsored work by OEHHA to compile a list of indicators of climate change in California under their Environmental Protection Indicators for California program. Environmental indicators present scientifically-based information on the status of, and trends in, environmental conditions over time. These indicators are intended to assist environmental programs in evaluating the outcomes of their efforts and in identifying areas that require more attention.This report identifies 27 indicators that measure the impact of climate change on the state's temperatures, precipitation, land, water, people, plants, and animals. It concludes that changes in California are consistent with those occurring globally. This report documents that climate change is occurring in California with important consequences for the future. By monitoring these indicators, we can measure the impacts of climate change and provide information that helps regulators develop policies to respond to them.

September 27, 2006- Global Warming Solutions Act of 2006
To respond to the challenge of climate change, the California Global Warming Solutions Act of 2006 (Assembly Bill 32 - Núñez ) was signed into law. California's landmark bill established a first-in-the-world comprehensive program of regulatory and market mechanisms to achieve real, quantifiable, cost-effective reductions of greenhouse gases. AB 32 provides authority for multiple efforts to mitigate greenhouse gas emissions. The law sets an economy-wide cap on California greenhouse gas emissions at 1990 levels by no later than 2020 and establishes a goal of reducing emissions to 80 percent below 1990 emission levels in 2050.

Senate Bill 1368 (Stats. 2006, Ch. 598) was passed which required the Public Utilities Commission and the Energy Commission to implement an emissions performance standard for all retail providers of electricity in the state. For any long-term commitment (five years or longer) to buy or build generation to serve California retail customers, emissions must be limited to 1,100 pounds of carbon dioxide (CO2) per megawatt-hour of electricity delivered. This is roughly equivalent to the emissions from a new combined cycle natural gas turbine.
October 18, 2006- Executive Order S-20-06 creates Advisory Committees for AB 32
