ACCUs are a financial product that equate to a tangible reduction of carbon dioxide or carbon dioxide equivalent in the atmosphere. Each ACCU represents one tonne of CO2-equivalent (CO2-e) greenhouse gas emissions avoided or removed from the atmosphere. 
Additionality Going beyond ‘business as usual’ to undertake additional activities to mitigate greenhouse gas concentrations and the danger of climate change. Additionality is one of several ‘integrity principles’ for Carbon Farming Initiative (CFI) projects. Under the CFI, additional activities are those on the ‘positive list’ under the Carbon Credits (Carbon Farming Initiative) Regulations 2011.
Agriculture, Forestry and Other Land Use (AFOLU) The Agriculture, Forestry and Other Land Use (AFOLU) sector is one of the contributors of greenhouse gas (GHG) emissions globally, producing about one-fourth of global GHG emissions.

Each ACCU represents one tonne of CO2-equivalent (CO2-e) greenhouse gas emissions avoided or removed from the atmosphere. 
Carbon footprint A carbon footprint is the total amount of greenhouse gases (including carbon dioxide and methane) that are generated by an activity, commonly used at an individual, household, organisation or product level.
Carbon neutrality Carbon neutrality refers to achieving a net carbon footprint of zero, and can be achieved through the acquisition and retirement of carbon offsets that meet additionality criteria. The term is often applied to an entire organisation (or committed individual), but can also be applied to a product or activity (such as air travel).
Carbon offset A reduction or removal of emissions of carbon dioxide or other greenhouse gases made in order to compensate for emissions made elsewhere. Carbon offsets are tradeable and often used to negate (or offset) all or part of another entity’s emissions.
Carbon Farming Initiative (CFI) The CFI is a legislative scheme that provides for credits to be issued in return for the abatement of greenhouse gases (i.e. reduced or avoided emissions and removals) through activities in the land sector.

Paris Agreement The Paris Agreement is a  legally binding international treaty on climate change, adopted in 2015. It covers climate change mitigation, adaptation, and finance. The agreement aims to substantially reduce global greenhouse gas emissions in an effort to limit the global temperature increase in this century to 2 degrees Celsius above preindustrial levels, while pursuing the means to limit the increase to 1.5 degrees.
Permanence

Permanence reflects the reality that sequestration or avoided emissions associated with stored carbon stocks can be reversed if those stocks are lost.

Under many systems permanence is handled through effective insurance mechanisms (with buffer accounts) rather than guaranteed storage times which you can imagine are problematic in international circumstances (as well as for many landowners)

Recognised Energy Savings Activity (RESA) Eligible Activities that fall into the NSW State Government’s Energy Savings Scheme.
REDD+ REDD+ is a framework created by the UNFCCC Conference of the Parties (COP) to guide activities in the forest sector that reduces emissions from deforestation and forest degradation, as well as the sustainable management of forests and the conservation and enhancement of forest carbon stocks in developing countries.
Safeguard Mechanism The Australian Government’s Department of the Environment and Energy’ Safeguard Mechanism’  requires Australia’s largest greenhouse gas emitters to keep their net emissions below a baseline.
Scope 1 emissions Scope 1 is direct emissions from company-owned and controlled resources. This includes manufacturing processes, emissions from office energy consumption, and company vehicles. It is essentially all the emissions the company itself creates to make its product or deliver its services. Scope 1 emissions are sometimes referred to as direct emissions.
Scope 2 emissions Scope 2 are indirect emissions from the generation of purchased energy. That means, taking into account emissions that are created to generate the energy that an organisation purchases from a utility provider. The actual use of the energy is counted in scope 1. Scope 2 is about taking accountability for the ripple effect of generating the energy in the first place.
Scope 3 emissions Indirect greenhouse gas emissions other than scope 2 emissions that are generated in the wider economy. They occur as a consequence of the activities of a facility, but from sources not owned or controlled by that facility’s business. It includes all the upstream and downstream emissions related to the company’s activities. For example, if the company sells a product, scope 3 takes into account the emissions generated from the use of that product by the customer. It also takes into account the emissions generated to produce the things that go into making the product. For example, materials, components, parts or ingredients. It even takes into account things like office furniture, IT support, employee travel, transportation and distribution, and end of life – which means looking at how packaging or waste generated are disposed of.

(b) dead matter (other than dead roots) attached to a living tree. 

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 sources.
Allometric Equations Allometry is the study of the relationship between size and shape. Allometric equations are derived from direct measurement  to predict above and below ground biomass from easily measurable attributes, such as tree height and stem diameter.
Avoided Deforestation (AD) AD refers to avoiding emissions of greenhouse gases attributable to the clearing and conversion of native forest land to non-forest. Avoided deforestation can also enhance forest carbon stocks by removing carbon dioxide from the atmosphere by sequestering carbon in trees in one or more native forests.

Carbon Estimation Area is a stratum of the Project Area that has consistent physical characteristics, and is established and managed in a consistent way.

The Planted Areas are divided (stratified) into Carbon Estimation Areas (CEAs) according to site characteristics and management routines that affect growth. A CEA is not necessarily contiguous as long as the site characteristics and management practices are uniform.

CEA areas within the Project Area that will be monitored for carbon sequestration. Each CEA should be internally consistent in terms of vegetation formation, soil type, historical and planned management regime, and the stage of regrowth forest development. This allows carbon accumulation in areas with different characteristics or management to be measured separately.

Reforestation

The direct human-induced conversion of non-forest land to forested land via the planting, seeding and/or the human-induced promotion of natural seed sources, on land that was forested but that has been converted to non-forest land. For Kyoto accounting, reforestation specifically refers to conversion of land that was not forest land at the end of 1989. Unlike the Kyoto rules, the CFI currently does not include human induced forest regrowth on land clear of forest at 1990 under reforestation. Therefore, there is a risk that managed regrowth projects in such situations will not attract Kyoto compliant carbon credits. However, managed regrowth on land deforested since 1990 is a reversal of an emission and should therefore attract Kyoto compliant carbon credits.
