The baseline is the emission of greenhouse gases that would occur without the intended project activity or policy intervention. It therefore represents the emissions associated with a business-as-usual scenario. The additional emission reductions that a project contributes can only be determined once the baseline has been assessed. Various approaches can be taken to determine the baseline, but the approach must be justified as part of the project validation process.
An allocation method in which allowances are distributed based on output (e.g. one allowance per MWh generated) or on intensity standards in the industry, based on best-performing companies.
A mechanism under a cap and trade system that allows entities to use allowances designated for a future compliance period to meet current compliance period requirements.
A bubble is said to exist when emissions for different countries are grouped together, and the target applies to the group. E.g. The European Union.
Bundling signifies the bringing together of several CDM project activities, to form a single project to reduce CDM-related transaction costs.
A business as usual scenario is a policy neutral reference case of future emissions, i.e. projections of future emission levels in the absence of changes in current policies, economics and technology.
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.
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.
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.
