Additionality: To be a robust offset, a project must be proven to be 'additional' to what would have occurred anyway. Additionality has 3 main components:
- financial additionality where the project needs to go beyond business as usual practice,
- regulatory additionality where the project needs to go beyond existing legal requirements, and
- environmental additionality where the emission reductions cannot be counted toward another emission reduction scheme or commitment.

The six gases are: carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), HFCs (hydrofluorocarbons), PFCs (perfluorocarbons) and sulphur hexafluoride (SF6). it is permitted to produce. These systems allow those who reduce emissions beyond their obligations to sell their excess emission capacity to others within the ETS who are unable to meet their own emission reduction targets. There are two broad types of emissions trading schemes, cap and tradeA term used to describe an emissions trading system, where total emissions are limited or 'capped'. Permits are issued up to that cap, and a market allows those participants emitting less than the quota to sell their excess permits to emitters needing to buy extra permits to meet their quota. and baseline and credit.
Forward crediting: The buyer pays for and receives a certain number of offsets for emissions reductions or sequestration that will occur in the future. See also Forward sellThe sale of carbon offsets for emissions reductions or sequestration that have not yet occurred and therefore can not be precisely measured..
Forward delivery: The buyer pays the purchase price for a certain number of offsets that have yet to be produced. The offsets will be delivered to the buyer once they have been realised and verified.
Forward purchases: The buyer invests the money upfront but does not get the credits until they are actually produced. These are long-term commitments that are predominantly done on a large scale.

GWP is a relative scale, where CO2 = 1. The other gases are given a number based on their effect on the atmosphere relative to CO2. For example, methane has a GWP of 21, meaning it has 21 times the amount of heating capacity of CO2.. If a company emits less greenhouse gases than authorised they can sell their permits within the trading scheme.
Perofluorocarbons (PFCs): Most emissions of PFCsMost emissions of PFCs in Australia are generated during aluminium production. PFCs have extremely high global warming potentials (5000 to 10,000 times that of carbon dioxide). However, because they are only released in relatively small amounts, their contribution to global warming is minor. Due to their stability they have very long atmospheric lifetimes (thousands of years). in Australia are generated during aluminium production.

Renewable resources: A natural resource qualifies as a renewable resourceA natural resource qualifies as a renewable resource if it is replenished by natural processes at a rate comparable to its rate of consumption. Oxygen, fresh water, timber, and biomass can all be considered renewable resources. However they can become non-renewable resources if used at a rate greater than the environment's capacity to replenish them. if it is replenished by natural processes at a rate comparable to its rate of consumption. Oxygen, fresh water, timber, and biomassBiomass is non-fossilized and organic biodegradable material that can be used as fuel or for industrial production. Most commonly, biomass refers to plant matter grown for use as Biofuels, but it also includes plant or animal matter used for production of fibres, chemicals or heat. Biomass may also include biodegradable wastes that can be burnt as fuel. can all be considered renewable resources. However they can become non-renewable resources if used at a rate greater than the environment's capacity to replenish them.
Retailer: Carbon offset retailers either fund or purchase carbon offsets in large quantities and then on sell them to individual consumers in smaller quantities.
Retire: In the context of carbon offsets, this means to remove a carbon credit or permit from the market. As a result of retirement those offsets cannot be traded any further. Retiring offsets is a means of regulating offsetting and preventing companies and individuals from selling or buying offsets that have already been used.
RFI: Radiative Forcing is the change in radiation received at the surface of the earth due to the emission of greenhouse gasesGreenhouse Gases in the earth's atmosphere absorb and re-emit infrared radiation. The Kyoto Protocol lists six major greenhouse gases, which vary in their relative warming effect. The six gases are: carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), HFCs (hydrofluorocarbons), PFCs (perfluorocarbons) and sulphur hexafluoride (SF6).. The Radiative Forcing Index calculates the impact non-CO2A greenhouse gas that is produced as a by-product of oil and gas production, burning fossil fuels and biomass, as well as from all animals, plants, and a number of other natural sources.

RMUs: Removal Units are carbon credits that are derived from LULUCFA Kyoto Protocol acronym that stands for human-induced 'Land Use, Land-Use Change and Forestry'. Some of these activities result in greenhouse emissions and some lead to greenhouse gases being removed from the atmosphere. For example, land clearing generates greenhouse gas emissions. Planting trees can lead to greenhouse gases being absorbed from the atmosphere. projects in industrialised countries that absorb carbon dioxideA greenhouse gas that is produced as a by-product of oil and gas production, burning fossil fuels and biomass, as well as from all animals, plants, and a number of other natural sources.

Surrender: In an ETSAn ETS is an organised system of emissions trading that can be applied within businesses, states, countries and also internationally. Through an ETS an organisation is allocated an allowance for the amount of greenhouse gases it is permitted to produce. These systems allow those who reduce emissions beyond their obligations to sell their excess emission capacity to others within the ETS who are unable to meet their own emission reduction targets. There are two broad types of emissions trading schemes, cap and trade and baseline and credit., countries or businesses are allocated carbon credits or permits, usually for a designated time frame. They must then surrenderIn an ETS, countries or businesses are allocated carbon credits or permits, usually for a designated time frame. They must then surrender one carbon credit for each tonne of carbon dioxide equivalent (CO2e) emitted within the relevant time frame. This ensures the credits are not double-counted. one carbon credit for each tonne of carbon dioxide equivalentCarbon dioxide equivalent.
