Glossary of Terms: S

Seasonal Allotment Period: In the Illinois ERMs program, the period from May 1 through September 30 of each year.

Seasonal Emissions: In the Illinois ERMs program, the actual volatile organic material emissions at a Paticipating Source that occur during a Seasonal Allotment Period.

Small scale CDM projects: There is a simplified process for small scale CDM projects that will generate less emissions reductions. They are defined as: renewable energy projects under 15 MW, energy efficiency projects that reduce energy consumption by up to 15 GWh per year; or project activities which emit less than 15 kilotonnes CO2 equivalent per year.

"Spill-over effects": Reverberations in developing countries caused by actions taken by developed countries to cut greenhouse-gas emissions. For example, emissions reductions in developed countries could lower demand for oil and thus international oil prices, leading to more use of oil and greater emissions in developing nations, partially off-setting the original cuts. Current estimates are that full-scale implementation of the Kyoto Protocol may cause 5 to 20 per cent of emissions reductions in industrialized countries to "leak" into developing countries.

Source: Any process or activity which releases a greenhouse gas, an aerosol or a precursor of a greenhouse gas into the atmosphere (source: UNFCCC)

South Coast Air Quality Management District: The SCAQMD is the entity that governs sources emitting air pollution in the four county Los Angeles metropolitan area and administers the RECLAIM cap and trade program and the Regulation XIII new source review program.

SOx Allowance: An emission right issued by the US EPA under Title IV of the Clean Air Act Amendments of 1990 that gives authorization to emit one ton of SO2 emissions on or after the vintage pursuant to the rules of the Acid Rain program. SO2 Allowances may be used during their vintage year or banked and used in subsequent years.

SOx Emissions: Emissions of sulfur dioxides.

Stakeholders: The public, including individuals, groups or communities affected, or likely to be affected, by the
project. Comments of stakeholders have to be included into Project Design Document according to rules established by UNFCCC.

Static Baseline: A baseline assuming that business conditions are to remain constant and apply throughout the lifetime of the project.

Sulphur hexofluoride (SF6): Sulphur hexafluoride is an extremely potent greenhouse gas with a global warming potential (GWP) of 22,200. SF6 is has long-lasting effects, with an atmospheric lifetime of 3,200 years. A relatively small amount of SF6 can have a significant impact on global climate change.

Supplementarity: A Kyoto Protocol requirement that adequate domestic energy and other policies exist to ensure the achievement of long-term emission reduction goals. The supplementary rule is still open to interpretation however it reflects the request of the European Union to limit the use of the Kyoto Protocol flexibility mechanisms.

Sustainable Development: development that meets the needs of the present without compromising the ability of future generations to meet their needs.
