What You'll Learn

California's cap-and-trade system
The system works by obliging these entities to purchase permits, which they must retire annually against their entity-level targets. Auctions for these permits are held on a quarterly basis. The revenue generated from these auctions is deposited into the state's Greenhouse Gas Reduction Fund, with 35% directed by law to environmentally disadvantaged and low-income communities. The fund supports various projects, from light rail systems to electric bike-sharing initiatives, climate-smart agriculture, distributed electricity, and solar-plus-storage solutions.
California's cap-and-trade program is one of the largest multi-sectoral emissions trading systems in the world. It is linked with the Canadian province of Quebec's cap-and-trade system through the Western Climate Initiative. Since its launch in 2013, California has seen a 5.3% decrease in statewide greenhouse gas emissions from 2013 to 2017, with investments of billions of dollars in emission-reducing projects.
The program is central to California's ambitious goals of reducing emissions to 1990 levels by 2020 (a target met in 2016), 40% below 1990 levels by 2030, and 80% below 1990 levels by 2050. The state also aims for 100% carbon-free electricity and economy-wide carbon neutrality by 2045.

Greenhouse gas emissions reduction targets
In 2016, California Governor Jerry Brown signed two laws designed to be the most ambitious initiative on climate change in the country. These laws extended the state's pioneering cap-and-trade program and established new goals for reducing greenhouse gas emissions.
The first law, SB 32, extended the state's previous goal of cutting emissions to 1990 levels by 2020, which the governor's office stated was on track to be met. SB 32 set a new target of reducing emissions to 40% below 1990 levels by 2030, making it the most ambitious greenhouse gas emission reduction target in North America. This target was later reinforced by Governor Brown's signing of SB 100, The 100 Percent Clean Energy Act of 2018, which aimed to achieve carbon neutrality by 2045.
The second law, AB 32, mandated that the state generate half of its electricity from renewable sources by 2030. This law also established the nation's toughest restrictions on destructive super pollutants. These laws were met with opposition from industry lobbyists and the business community, who argued that they did not consider the economic impact on the state.
Governor Brown's commitment to reducing greenhouse gas emissions was further demonstrated through his involvement in various coalitions and initiatives. He played a role in the U.S. Climate Alliance and the Under2 Coalition, both committed to curbing carbon pollution and limiting the increase in global average temperature. Additionally, Brown launched America's Pledge on climate change to drive down greenhouse gas emissions in alignment with the goals of the Paris Agreement.

Pollution in poor communities
In 2016, California Governor Jerry Brown signed two laws designed to combat climate change and reduce greenhouse gas emissions. These laws aimed to extend the state's cap-and-trade program and invest in poor communities disproportionately affected by climate change. The cap-and-trade program allows companies to buy permits to pollute, with the revenue generated being used to fund public transit and affordable housing to reduce emissions.
While these laws were praised by some as ambitious and necessary, they faced opposition from industry lobbyists and business communities. Critics argued that the laws did not adequately consider the economic impact on the state and that they fell short of what was needed to address climate change. Additionally, there has been criticism of Governor Brown's relationship with the oil industry, with some arguing that he has approved too many drilling permits and conceded key concessions to oil interests.
In 2018, Governor Brown took further action by signing SB 100, The 100 Percent Clean Energy Act, which set a goal for California to achieve carbon neutrality and transition to 100% renewable energy by 2045. This was accompanied by an executive order directing state agencies to develop measures to achieve carbon neutrality. These initiatives build upon California's previous commitment to reduce emissions to 40% below 1990 levels by 2030, which was established through the SB 32 statute.
The efforts to address climate change and pollution in California, including investments in poor communities, are significant steps towards a more sustainable future. However, the state continues to face challenges in balancing economic interests with environmental protection and ensuring that the burden of reducing emissions is shared equitably across sectors. By investing in public transit and affordable housing, California is taking a proactive approach to reducing emissions and improving the quality of life for its residents, especially in disadvantaged communities.

Fracking regulation
In 2016, California Governor Jerry Brown signed two laws designed to combat climate change and reduce the state's carbon footprint. These laws extended the state's cap-and-trade program, which allows companies to buy permits to pollute, with the revenue generated being used to fund public transit and transit-oriented affordable housing to reduce emissions. The laws also established ambitious goals for reducing greenhouse gas emissions, aiming for a 40% reduction below 1990 levels by 2030.
In addition to these laws, Governor Brown also signed legislation regulating fracking, which was called the toughest in the nation. However, this law fell short of a complete ban on fracking, which some environmentalists had advocated for. Governor Brown has been criticised for his close ties to the oil industry and for approving thousands of new drilling permits during his tenure. Despite this, California has made significant progress under his leadership, creating millions of new jobs and eliminating a budget deficit while also pursuing ambitious environmental goals.
While the exact details of the fracking regulation law are not provided in the sources, it is clear that Governor Brown intended to strike a balance between environmental protection and the needs of the oil industry. This approach has drawn criticism from some environmentalists who argue that a complete ban on fracking is necessary to protect the state's natural resources and reduce the risk of environmental disasters associated with the practice.
Despite the criticism, Governor Brown maintained that his administration was committed to addressing climate change and transitioning California to a clean energy economy. The state's cap-and-trade program and ambitious emissions reduction targets are testament to this commitment, and California continues to be a leader in renewable energy and environmental policy.

Carbon neutrality goals
California Governor Jerry Brown has been at the forefront of the state's efforts to combat climate change and reduce carbon emissions. In 2018, he signed SB 100, The 100 Percent Clean Energy Act, which aims to transition California to 100% renewable energy sources by 2045. This ambitious target establishes a statewide policy for eligible renewable energy and zero-carbon resources to power all retail sales of electricity within the state.
In conjunction with SB 100, Governor Brown issued Executive Order B-55-18, which sets an even more aggressive goal of achieving carbon neutrality by 2045. This order requires the California Air Resources Board (CARB) to collaborate with relevant state agencies to identify and implement measures to reach carbon neutrality. The executive order builds upon California's existing emissions reduction targets, including the goal of reducing greenhouse gas emissions to 40% below 1990 levels by 2030, which is among the most ambitious in North America.
The state's commitment to carbon neutrality involves not only reducing emissions but also offsetting remaining emissions through various methods. One approach is to utilize natural and working lands, such as forests, soils, and other landscapes, to sequester carbon dioxide from the atmosphere. However, there are uncertainties regarding the availability and accounting of these land-based carbon sinks, which may require emitting sectors to accelerate their emission reduction efforts.
Governor Brown's initiatives extend beyond just legislation. He has also built coalitions, such as the U.S. Climate Alliance and the Under2 Coalition, committed to curbing carbon pollution and limiting global temperature rise. Additionally, he launched America's Pledge to compile and quantify the actions of states, cities, and businesses working towards reducing greenhouse gas emissions in line with the Paris Agreement. These efforts demonstrate Governor Brown's dedication to driving systemic change and achieving carbon neutrality goals in California and beyond.
