Abatement
Refers to reducing the degree or intensity of greenhouse-gas emissions.
Ablation (Glacial)
All processes, which include melting, evaporation (sublimation), wind erosion, and calving (breaking off of ice masses), that remove snow or ice from a glacier or snowfield. The term also refers to the amount of snow or ice removed by these processes.
Abscission
Shedding by a plant of its parts, such as leaves, flowers, fruits, or seeds. The process is regulated by the plant hormone abscisic acid.
Absorption Coefficient
A measure of the amount of radiant energy, incident normal to a planar surface, that is absorbed per unit distance or unit mass of a substance.
ACCC
Australian Competition and Consumer Commission. An independent Commonwealth statutory authority formed in 1995 to administer the Trade Practices Act 1974 and other acts. The ACCC promotes competition and fair trade in the market place to benefit consumers, business and the community. Its primary responsibility is to ensure that individuals and businesses comply with the Commonwealth competition, fair trading and consumer protection laws.
Accession
An act whereby a State becomes a Party to a treaty already negotiated and signed by other States; has the same legal effect as ratification.
Acclimation (acclimatisation)
Change that occurs in an organism to allow it to tolerate a new environment.
Accredited Independent Entity (AIE)
An entity accredited by the JISC, which is responsible for the determination of whether a carbon reduction project and the ensuing reductions of anthropogenic emissions by sources or enhancements of anthropogenic removals by sinks meet the relevant requirements of Article 6 of the Kyoto Protocol and the JI guidelines and can generate carbon emission credits.
Accumulation (Glacial)
All processes, which include snowfall, condensation, avalanching, snow transport by wind, and freezing of liquid water, that add snow or ice to a glacier, floating ice, or snow cover. The term also includes the amount of snow or other solid precipitation added to a glacier or snowfield by these processes.
Activities implemented jointly (AIJ)
Activities carried out under the Convention to mitigate climate change through partnerships between a carbon investor from a developed country and a counterpart in a host country under a pilot phase that ended in the year 2000. The purpose was to involve private-sector money in the transfer of technology and know-how. See also Joint Implementation
Ad hoc Group on Article 13 (AG13)
A subsidiary body (committee) created by COP-1 to explore how to help governments overcome difficulties experienced in meeting their commitments under the Climate Change Convention (1995-1998).
Adaptation
Adjustment in natural or human systems in response to actual or expected climatic stimuli or their effects, which moderates harm or exploits beneficial opportunities.
Adaptation Fund
The Adaptation Fund was established to finance concrete adaptation projects and programmes in developing countries that are Parties to the Kyoto Protocol. The Fund is to be financed with a share of proceeds from Clean Development Mechanism (CDM) project activities and receive funds from other sources.
Adaptation Levy
Levy aims to assist "Least Developed Countries" (LDCs) through Adaptation Fund to adapt to climate change. Levy (2% of the certificates from project) is imposed to all CDM projects except those implemented in LDCs.
Additionality
A key eligibility test for carbon projects designed to generate carbon emission credits under the Kyoto Protocol's CDM and JI programmes, as well as other carbon emission reduction schemes. This test dictates that projects are only eligible for carbon investment if the resulting emission reductions weren't going to happen anyway, ie. they are additional to what would have occurred without the carbon credit incentive.
Ad-Hoc Working Group on Further Commitments

aerosol
Particulate material, other than water or ice, in the atmosphere ranging in size from approximately 10x-3 to larger than 10x-2 m in radius. Aerosols are important in the atmosphere as nuclei for the condensation of water droplets and ice crystals, as participants in various chemical cycles, and as absorbers and scatterers of solar radiation, thereby influencing the radiation budget of the earth-atmosphere system, which in turn influences the climate on the surface of the Earth.
Afforestation
The direct human-induced conversion of land that has not been forested for a period of at least 50 years to forested land through planting, seeding and/or the human-induced promotion of natural seed. Eligible under the Kyoto Protocol for Carbon Emissions Credits.
Afforestation and Reforestation (A/R) Projects
Afforestation and reforestation (A/R) projects imply establishment of forest on land that has not been forested for a period of at least 50 years (afforestation) or on non-forested land (reforestation) through planting, seeding and/or the promotion of natural seed sources. Emissions reductions are made through sequestration of emissions.

Baseline and credit
A type of emissions trading scheme where firms are encouraged to reduce their greenhouse gas emissions below a projected “business as usual” path of increasing emissions. Any reductions below that future path earns credits for the difference which can be sold to other emitters struggling to contain increases to baseline levels. See also cap and trade.

Biodegradable materials
Materials capable of being broken down rapidly by living organisms such as bacteria and fungi. This natural process of decay usually makes the materials harmless in a relatively short period of time. Food, sewage and most natural organic substances are biodegradable but manufactured materials such as glass, heavy metals and most types of plastic are not biodegradable.
Bio-Fuels
Bio-Fuels are renewable fuels made from plants that can be used to supplement or replace the fossil fuels petroleum and diesel used for transport. The two main bio-fuels are ethanol and bio-diesel. Ethanol is produced from the fermentation of sugar or starch in crops such as corn and sugar cane. Bio-Diesel is made from vegetable oils in crops such as soybean, or from animal fats. Depending on the processes used to make bio-fuels, greenhouse emissions from cars and fuel-powered machinery can be substantially reduced by their use.
biogeochemical cycle
The chemical interactions among the atmosphere, biosphere, hydrosphere, and lithosphere.
biological productivity
The amount of organic matter, carbon, or energy content that is accumulated during a given time period.
Biomass fuels or biofuels
A fuel produced from dry organic matter or combustible oils produced by plants. These fuels are considered renewable as long as the vegetation producing them is maintained or replanted, such as firewood, alcohol fermented from sugar, and combustible oils extracted from soy beans. Their use in place of fossil fuels cuts greenhouse gas emissions because the plants that are the fuel sources capture carbon dioxide from the atmosphere.
Bio-Sequestration (BS)
Reduction of existing atmospheric carbon dioxide (CO2) through capture and storage in plants and soils.
biosphere
The portion of Earth and its atmosphere that can support life. The part (reservoir) of the global carbon cycle that includes living organisms (plants and animals) and life- derived organic matter (litter, detritus). The terrestrial biosphere includes the living biota (plants and animals) and the litter and soil organic matter on land, and the marine biosphere includes the biota and detritus in the oceans.
biota
The animal and plant (fauna and flora) life of a given area.
Bonn agreements

Bonn fund
A special UNFCCC fund for contributions from the Government of Germany to cover costs of UNFCCC events held in Bonn.
Brazilian proposal
A proposal by the delegation of Brazil made in May 1997 as part of the negotiations on the Kyoto Protocol. It included a formula to set differentiated emission reduction targets for Parties based to the cumulative impact of Parties’ historic emissions on the global average surface temperature.
Bubble
A bubble is a regulatory concept whereby two or more emission sources are treated as if they were a single emission source.
Buffer Factor (Revelle Factor)
The ratio of the instantaneous fractional change in the partial pressure of CO2 (pCO2) exerted by seawater to the fractional change in total CO2 dissolved in the ocean waters. The buffer factor relates the partial pressure of CO2 in the ocean to the total ocean CO2 concentration at constant temperature, alkalinity and salinity. The Revelle factor is a useful parameter for examining the distribution of CO2 between the atmosphere and the ocean, and measures in part the amount of CO2 that can be dissolved in the mixed surface layer.
Bundling, see also Debundling
Combination of several small-scale project activities to form a single project activity or portfolio to decrease transaction costs per unit of emission reductions.
Bunker fuels
A term used to refer to fuels consumed for international marine and air transport.
