Message definition (Greenhouse gas emissions by the United States)
====California====
* Vehicle Air Pollution (Senate Resolution 27): States and implies that California does not have to adhere to cutbacks in federal emissions standards, thereby allowing stricter California emissions standards than the federal government. This Senate Resolution stems from the previous administration's efforts to reverse environmental policies, and in this case, vehicle emissions standards. California's authority to set its own emissions standards is allowed through California's Clean Air Act [[Federal preemption|preemption]] waiver granted to the state by the EPA in 2009.  California's waiver applies to vehicles made in 2009 and later. The previous state standard included a goal for certain vehicles to reach an average 35 miles per gallon. California saw a large decline in vehicle emissions from 2007 to 2013 but a rise in emissions following 2013, which can be attributed to different circumstances, some of which include population and employment growth, and increases in overall state GDP indicating more economic activity in the state.
* [[Emissions trading|Cap-and-Trade Program]]: Market-based [[carbon price|carbon pricing]] program that sets a statewide cap on emissions. This cap declines annually and applies to large emitters that account for over 80 percent of California's GHG emissions. The [[California Air Resources Board]] (CARB) creates an allowance for each ton of carbon dioxide emissions. The number of allowances decreases over time and incentivizes a flexible approach to emissions reduction through trading.
* Advanced Clean Cars: Addresses GHG emissions and criteria air pollutants in California through the Low-Emission Vehicle (LEV) regulation and the [[Zero-emissions vehicle|Zero-Emission Vehicle]] (ZEV) regulation. The LEV regulation establishes increasing emissions standards for passenger vehicles through model year 2025. The ZEV regulation requires vehicle manufacturers to sell a certain percentage of ZEVs and plug-in hybrids annually through 2025. The next iteration of this program for future model years is under development. 15 states have adopted the regulations under this program.
* Advanced Clean Cars II: Mandates a ban on the sale of internal combustion engine passenger vehicles, trucks, and SUVs starting in 2035, and mandates annual increases in ZEV sales targets from model year 2026 to 2035. California has adopted the regulation and New York announced that it would follow.
* Advanced Clean Trucks: Requires manufacturers of medium-and heavy-duty trucks to sell an increasing percentage of zero-emission trucks each year starting with model year 2024. In addition to California, Oregon, Washington, New Jersey, New York, and Massachusetts have also adopted this regulation. 10 other states and the District of Columbia intend to adopt in the future.
* [[Low-carbon fuel standard|Low Carbon Fuel Standard]] (LCFS): Establishes annual targets through 2030 to ensure transportation-related fuels become cleaner and less carbon intensive. Oregon has a similar program entitled, Clean Fuels Program, which runs until 2025.
* In 2006, the state of California passed AB-32 ([[Global Warming Solutions Act of 2006]]), which requires California to reduce greenhouse gas emissions. To implement AB-32, the California Air Resources Board proposed a [[carbon tax]] but this was not enacted.
* In May 2008, the [[Bay Area Air Quality Management District]], which covers nine counties in the [[San Francisco Bay Area]], passed a carbon tax on businesses of 4.4 cents per ton of CO<sub>2</sub>.
