1. California Air Resources Board (CARB)

   The California Air Resources Board, also known as (ARB) is the "clean air agency" in the government of California. Established in 1967 in the Mulford-Carrell Act, combining the Bureau of Air Sanitation and the Motor Vehicle Pollution Control Board, the ARB is a department within the cabinet-level California Environmental Protection Agency. The stated goals of ARB include attaining and maintaining healthy air quality; protecting the public from exposure to toxic air contaminants; and providing innovative approaches for complying with air pollution rules and regulations.

2. California Climate Action Registry (CCAR)

   A non-profit voluntary registry for greenhouse gas emissions in California and the official registry for AB32. The purpose of the Registry is to help companies and organisations with operations in the state to establish GHG emission baselines against which any future GHG emission reduction requirements may be applied.

3. Cap and Trade

   The most popular type of emissions trading scheme where emissions are subject to a cap, permits are issued up to that cap, and a market allows those emitting less than their quota of the cap to sell their excess permits to emitters needing to buy extra to meet their quota. See also baseline and credit.

5. Carbon Capture and Storage (CCS)

   A two-step measure to prevent carbon dioxide emissions from the burning of fossil fuels entering the atmosphere, particularly from power generation. Instead of CO2 being vented, it is contained and pumped underground under pressure, where it cannot contribute to global warming. This technology is still in its infancy with results largely unproven. Also known as one form of 'carbon sequestration'.

6. Carbon Dioxide Equivalent (CO2e)

   Measurement unit used to indicate the global warming potential (GWP) of greenhouse gases. Carbon dioxide is the reference gas against which other greenhouse gases are measured. See Global Warming Potential for conversion rates.

7. Carbon Emission Factor (CEF)

   Amount of CO2 released per unit of energy produced.

8. Carbon leakage

   Carbon leakage occurs when there is an increase in carbon dioxide emissions in one country as a result of an emissions reduction by a second country with a strict climate policy.

9. Carbon Neutrality

   An individual, household or organisation that is responsible for no net emissions of greenhouse gases from all its activities is considered "carbon neutral". Emissions must be cut to a minimum and any necessary emissions then offset by emission reducing activities elsewhere. Buying accredited clean electricity helps cut household or office greenhouse emissions, while investing in sustainable energy projects or afforestation schemes are examples of offsets.

10. Carbon Offset

    A carbon offset is a financial instrument aimed at a reduction in greenhouse gas emissions. Carbon offsets are measured in metric tons of carbon dioxide-equivalent (CO2e) and may represent six primary categories of greenhouse gases. One carbon offset represents the reduction of one metric ton of carbon dioxide or its equivalent in other greenhouse gases.
