The San Diego Climate Action Plan was adopted by the city of San Diego in December 2015. It is a local climate action plan whose rules are defined by the California global warming Solutions Act of 2006 (AB 32), with the goal of reducing greenhouse gas emissions. [1] Through this plan, the city initially set goals of eliminating half of all greenhouse emissions and sourcing all energy from renewable sources by the year 2035. With a coalition of business owners, environmental advocates, and community leaders, Mayor Kevin Faulconer approved the Climate Action Plan. The Climate Action Plan consists of several policies to ensure the economic and environmental growth of the city of San Diego. [2] It was referred to in The San Diego Union-Tribune as "the most aggressive climate action plan in California." [3]
The plan identifies five specific sectors:
Transportation was considered the largest sector of concern due to its overall contribution to greenhouse emissions and due to widespread reliance on high-emissions transportation methods. [4] To ensure progress of the plan, there are three phases of the Climate Action Plan: Phase 1: Early Action 2016-2017, Phase 2: Mid-Term 2018-2020, and Phase 3: Long-Term 2021-2035. Several departments within the local government and community will be involved to achieve the desire goal of a better future. [5] A Climate Action Campaign has begun in response to this plan with the help of organizations such as the Sierra Club. Yearly reports are to be made to track progression of this plan. [6] Much of the proposed transition to renewable energy relies on switching from SDG&E to a new community choice energy provider called San Diego Community Power. [7]
The five sectors identified by the city have been further divided into six specific strategies, each with individual targets. [8] Strategy 1, Decarbonization of the Built Environment, focuses on transforming city infrastructure to utilize cleaner energy sources. [8] San Diego Community Power has been tasked with supplying clean energy for new buildings as part of this decarbonization effort. [9] Strategy 2, Access to Clean and Renewable Energy, aims to provide alternative energy sources to reduce dependence on fossil fuels. [8] In effort to achieve this the city of San Diego has taken part in establishing a Joint Powers Authority with the cities of Chula Vista, Encinitas, Imperial Beach, and La Mesa to create an ordinance for a community choice authority on renewable energy. [10] Strategy 3, Mobility and Land Use, focuses on urban planning that prioritizes reliable and energy efficient transportation. [8] This includes the development of a Mobility Action Plan that aims to reduce cost, improves efficiency, and integrate climate resiliency into transportation infrastructure. [11] Strategy 4, Circular Economy and Clean Communities, is targeted towards waste reduction. [8] Progress towards this goal thus far has been linked to the City Recycling Ordinance which mandates recycling of eligible materials. [12] Strategy 5, Resilient Infrastructure and Healthy Ecosystems, involves integrating city infrastructure with the natural environment to adapt the city to be more resilient against natural disasters. [8] Efforts have been concentrated on developing an urban forest in Balboa Park. [13] Strategy 6, Emerging Climate Action, concentrates on the role of community partnerships to implement and monitor the previous five strategies. [8]
Goals focused on emissions reductions (measured in MT e, or metric tons of carbon dioxide equivalent) through 2035. The baseline used for the action plan was based on a 2010 report in which the total emissions were 12,984,993 MT of e. The projected emissions, if no changes were implemented, for the year 2020 is 14,124,690 MT of e, the year 2030 projection is 15,856,604 MT of e, and the year 2035 projection is 16,716,020 MT of e. [2] The climate action plan for the city of San Diego estimated reductions to 11,037, 244 MT of e by the year 2020, 7,790,996 MT of e by the year 2039, and 6,492,497 of MT of e by the year 2035. [2] Additionally, green job creation is one of the goals outlined in the action plan specifically for creating jobs in innovation and continuing the "green initiative" for the city. San Diego leaders emphasized job creation as the city was number seven on the 2017 U.S Clean Tech Leadership Index. [14] In the draft 2021 version of the plan, city leaders proposed changing the 2035 goal to net zero emissions. [15]
The San Diego City government has partnered with other local governments and organizations to advocate for decision making consistent with the city's climate action plan. [16] The city's renewable energy strategy is being supported by a county wide zero-carbon plan drafted by the county of San Diego with support from the UC San Diego School of Global Policy and Strategy. [17] Partnering with SANDAG and the San Diego Metropolitan Transit System has been integral to implementing transportation related policy including the 2021 Mid-Coast trolley extension. [18]
The 2018 San Diego Climate Action annual report outlines the progress of each of the five sectors. For the built environment and transportation sector, the three actions listed in the 2018 Climate action report exceeded the 2020 goal. The irrigation pumps did not produce any data, but the agriculture and conservation sector was seventy trees short of achieving the 14,000 trees planted goal. Water and waste water was able decrease the county's water consumption by 13% and the energy sector installed 38,510 home solar systems on existing houses. This is made possible in part by the Property Assessed Clean Energy (PACE), which allows owners to pay for their solar installation on their property taxes. [19]

The 2020 Climate Action Plan report stated that greenhouse gas emissions had been reduced by 25% compared to 2010, but this claim may be exaggerated because it relies on baseline assumptions that do not take into account reduced vehicle operation following the 2008 recession. [21] [22]
Assessing the state of implementation, environmental campaigner Nicole Kapretz said, "There’s been some progress, but it’s not even close to what we need. It’s baby steps when we need leaps." [23]
A 2021 city auditor's report found a lack of cost estimates, poor progress tracking, ambiguous responsibilities, and little communication, with interdepartmental meetings only occurring once a year in 2019 and 2020. [24] While the city agreed to implement recommendations from the auditor, the delay of the release of the mobility action plan was criticized by environmental groups. [24] [25]
In November 2021, an extension of the San Diego Trolley Blue Line was opened, potentially decreasing reliance on cars. [26]
As of 2022, the city had failed to meet its waste diversion target of 75% by 2020 and had remained around a 65% diversion rate since 2017. [27] The percentage of commuters not relying on cars has remained around 15%, and is projected to remain under 30% by 2035, well short of the city's goal of 50%. [28] A 2022 study by Todd Gloria's office found that the city's renewable energy projects could create about 60 to 90 new jobs annually from 2022 to 2035 but that eliminating gas infrastructure would lead to 60 to 65 fewer jobs per year. [29]
Climate change mitigation (or decarbonisation) is action to limit the greenhouse gases in the atmosphere that cause climate change. Climate change mitigation actions include conserving energy and replacing fossil fuels with clean energy sources. Secondary mitigation strategies include changes to land use and removing carbon dioxide (CO2) from the atmosphere. Current climate change mitigation policies are insufficient as they would still result in global warming of about 2.7 °C by 2100, significantly above the 2015 Paris Agreement's goal of limiting global warming to below 2 °C.
Clean technology, also called cleantech or climatetech, is any process, product, or service that reduces negative environmental impacts through significant energy efficiency improvements, the sustainable use of resources, or environmental protection activities. Clean technology includes a broad range of technology related to recycling, renewable energy, information technology, green transportation, electric motors, green chemistry, lighting, grey water, and more. Environmental finance is a method by which new clean technology projects can obtain financing through the generation of carbon credits. A project that is developed with concern for climate change mitigation is also known as a carbon project.
The United States produced 5.2 billion metric tons of carbon dioxide equivalent greenhouse gas (GHG) emissions in 2020, the second largest in the world after greenhouse gas emissions by China and among the countries with the highest greenhouse gas emissions per person. In 2019 China is estimated to have emitted 27% of world GHG, followed by the United States with 11%, then India with 6.6%. In total the United States has emitted a quarter of world GHG, more than any other country. Annual emissions are over 15 tons per person and, amongst the top eight emitters, is the highest country by greenhouse gas emissions per person.
China is both the world's largest energy consumer and the largest industrial country, and ensuring adequate energy supply to sustain economic growth has been a core concern of the Chinese Government since the founding of the People's Republic of China in 1949. Since the country's industrialization in the 1960s, China is currently the world's largest emitter of greenhouse gases, and coal in China is a major cause of global warming. However, from 2010 to 2015 China reduced energy consumption per unit of GDP by 18%, and CO2 emissions per unit of GDP by 20%. On a per-capita basis, China was only the world's 51st largest emitter of greenhouse gases in 2016. China is also the world's largest renewable energy producer, and the largest producer of hydroelectricity, solar power and wind power in the world. The energy policy of China is connected to its industrial policy, where the goals of China's industrial production dictate its energy demand managements.
The San Francisco Climate Action Plan is a greenhouse gas reduction initiative adopted by the City and County of San Francisco, United States in 2002. It aims to reduce the city's greenhouse gas emissions to 20% below 1990 levels by 2012. The plan was updated in 2013 to adopt an updated target of 40% below 1990 levels by 2025.
Canada was active in the negotiations that led to the Kyoto Protocol in 1997. The Liberal government that signed the accord in 1997 ratified it in parliament in 2002. Canada's Kyoto target was a 6% total reduction in greenhouse gas (GHG) emissions by 2012, compared to 1990 levels of 461 megatonnes (Mt). Despite signing the accord, greenhouse gas emissions increased approximately 24.1% between 1990 and 2008. In 2011, Conservative Prime Minister Stephen Harper withdrew Canada from the Kyoto Protocol.
Greenhouse gas emissions by Australia totalled 533 million tonnes CO2-equivalent based on greenhouse gas national inventory report data for 2019; representing per capita CO2e emissions of 21 tons, three times the global average. Coal was responsible for 30% of emissions. The national Greenhouse Gas Inventory estimates for the year to March 2021 were 494.2 million tonnes, which is 27.8 million tonnes, or 5.3%, lower than the previous year. It is 20.8% lower than in 2005. According to the government, the result reflects the decrease in transport emissions due to COVID-19 pandemic restrictions, reduced fugitive emissions, and reductions in emissions from electricity; however, there were increased greenhouse gas emissions from the land and agriculture sectors.
Energy in Switzerland is transitioning towards sustainability, targeting net zero emissions by 2050 and a 50% reduction in greenhouse gas emissions by 2030.
The climate change policy of the United States has major impacts on global climate change and global climate change mitigation. This is because the United States is the second largest emitter of greenhouse gasses in the world after China, and is among the countries with the highest greenhouse gas emissions per person in the world. Cumulatively, the United States has emitted over a trillion metric tons of greenhouse gases, more than any country in the world.
The Climate Action Plan (CAP) in Boulder, Colorado, is a set of strategies intended to guide community efforts for reducing greenhouse gas emissions. These strategies have focused on improving energy efficiency and conservation in homes and businesses—the source of nearly three-fourths of local emissions. The plan also promotes strategies to reduce emissions from transportation, which account for over 20 percent of local greenhouse gas sources.
The Chicago Climate Action Plan (CCAP) is Chicago's climate change mitigation and adaptation strategy that was adopted in September 2008. The CCAP has an overarching goal of reducing Chicago's greenhouse gas emissions to 80 percent below 1990 levels by 2050, with an interim goal of 25 percent below 1990 levels by 2020.
In 2021, net greenhouse gas (GHG) emissions in the United Kingdom (UK) were 427 million tonnes (Mt) carbon dioxide equivalent, 80% of which was carbon dioxide itself. Emissions increased by 5% in 2021 with the easing of COVID-19 restrictions, primarily due to the extra road transport. The UK has over time emitted about 3% of the world total human caused CO2, with a current rate under 1%, although the population is less than 1%.
The Sustainable Communities and Climate Protection Act of 2008, also known as Senate Bill 375 or SB 375, is a State of California law targeting greenhouse gas emissions from passenger vehicles. The Global Warming Solutions Act of 2006 sets goals for the reduction of statewide greenhouse gas emissions. Passenger vehicles are the single largest source of greenhouse gas emissions statewide, accounting for 30% of total emissions. SB 375 therefore provides key support to achieve the goals of AB 32.
Climate change has far reaching impacts on the natural environment and people of Finland. Finland was among the top five greenhouse gas emitters in 2001, on a per capita basis. Emissions increased to 58.8 million tonnes in 2016. Finland needs to triple its current cuts to emissions in order to be carbon neutral by 2035. Finland relies on coal and peat for its energy, but plans to phase out coal by 2029. Finland has a target of carbon neutrality by the year 2035 without carbon credits. The policies include nature conservation, more investments in trains, changes in taxation and more sustainable wood burning. After 2035 Finland will be carbon negative, meaning soaking more carbon than emitting.
Climate change has resulted in an increase in temperature of 2.3 °C (4.14 °F) (2022) in Europe compared to pre-industrial levels. Europe is the fastest warming continent in the world. Europe's climate is getting warmer due to anthropogenic activity. According to international climate experts, global temperature rise should not exceed 2 °C to prevent the most dangerous consequences of climate change; without reduction in greenhouse gas emissions, this could happen before 2050. Climate change has implications for all regions of Europe, with the extent and nature of impacts varying across the continent.
The Energiewende is the ongoing energy transition by Germany to a low carbon, environmentally sound, reliable, and affordable energy supply. The new system intends to rely heavily on renewable energy, energy efficiency, and energy demand management.
Climate change is leading to long-term impacts on agriculture in Germany, more intense heatwaves and coldwaves, flash and coastal flooding, and reduced water availability. Debates over how to address these long-term challenges caused by climate change have also sparked changes in the energy sector and in mitigation strategies. Germany's energiewende has been a significant political issue in German politics that has made coalition talks difficult for Angela Merkel's CDU.
China's greenhouse gas emissions are the largest of any country in the world both in production and consumption terms, and stem mainly from coal burning, including coal power, coal mining, and blast furnaces producing iron and steel. When measuring production-based emissions, China emitted over 14 gigatonnes (Gt) CO2eq of greenhouse gases in 2019, 27% of the world total. When measuring in consumption-based terms, which adds emissions associated with imported goods and extracts those associated with exported goods, China accounts for 13 gigatonnes (Gt) or 25% of global emissions. According to the Carbon Majors Database, Chinese state coal production alone accounts for 14% of historic global emissions.
Greenhouse gas emissionsbyRussia are mostly from fossil gas, oil and coal. Russia emits 2 or 3 billion tonnes CO2eq of greenhouse gases each year; about 4% of world emissions. Annual carbon dioxide emissions alone are about 12 tons per person, more than double the world average. Cutting greenhouse gas emissions, and therefore air pollution in Russia, would have health benefits greater than the cost. The country is the world's biggest methane emitter, and 4 billion dollars worth of methane was estimated to leak in 2019/20.
Global net zero emissions describes the state where emissions of greenhouse gases due to human activities, and removals of these gases, are in balance over a given period. It is often called simply net zero. In some cases, emissions refers to emissions of all greenhouse gases, and in others it refers only to emissions of carbon dioxide. To reach net zero targets requires actions to reduce emissions. One example would be by shifting from fossil fuel energy to sustainable energy sources. Organizations often offset their residual emissions by buying carbon credits.
