Reduction of greenhouse gas emissions, or enhancement of greenhouse gas removal from the atmosphere by sinks.

Business as Usual - used in the context of predicting future data on the basis of existing practices.
(CO2- e) A standard measure that takes account of the different global warming potentials of greenhouse gases and expresses the cumulative effect in a common unit.

A measure of the carbon dioxide equivalent emissions attributable to an activity; it is commonly used at an individual, household or organisation, product and service level.
From: Draft National Carbon Offset Standard, Australian Department of Climate Change,19 December 2008
Commonly refers to a situation where the net emissions associated with an organisation's activities, product or service are zero.

Represents a reduction in greenhouse gases relative to a businessas-usual baseline. Carbon offsets are tradeable and often used to negate (or offset) all or part of another entity's emissions.

(CER) A Kyoto unit corresponding to one metric tonne of carbon dioxide equivalent emissions, and issued for verified emission reductions or removals achieved by projects approved under the Clean Development Mechanism.

(GWP) A system of multipliers devised to enable warming effects of different gases to be compared. For example, over the next 100 years, a gram of methane in the atmosphere is currently estimated as having 21 times the warming effect as a gram of carbon dioxide; methane's 100-year global warming potential is thus 21.

The atmospheric gases responsible for causing global warming and climate change. The major GHGs are carbon dioxide (CO2), methane (CH4), nitrous oxide (N20), hydrofluorocarbons (HFCs), perfluorocarbons (PFCs) and sulphur hexafluoride (SF6).

One billion (thousand million) metric tonnes of CO2e (see: Carbon dioxide equivalent).

An international treaty created under the UNFCCC in 1997. It entered into force in 2005. Among other things, the Kyoto Protocol sets binding targets for the reduction of greenhouse gas emissions by developed countries. It includes individual emission reduction targets for Annex I countries to be met within the first commitment period of 2008-12.

"A mega joule is a unit of energy consumption. This relates all types of fuel to the amount of energy contained within that fuel. For instance gas, petrol and electricity have varying units of measure (cubic metres, litres, kilowatt hours) and a relevant concentration of energy (Mega joules per unit). When these are multiplied, we can know the exact amount of energy used. For instance, electricity is measured in electrical load times by length of load (ie kilowatt hours). To convert KWH into MJ, we simply multiply by 3.6. "

Metric tons of CO2e (see: carbon dioxide equivalent).

Definition:
This is a way of expressing very dilute concentrations of substances. Just as per cent means out of a hundred, so parts per million or ppm means out of a million. Usually describes the concentration of something in water or soil. One ppm is equivalent to 1 milligram of something per liter of water (mg/l) or 1 milligram of something per kilogram soil (mg/kg).

(UNFCCC) An international treaty, adopted in 1992, aimed at achieving the stabilisation of greenhouse gas concentrations in the atmosphere at a level that would prevent dangerous anthropogenic interference with the climate system.
