The Paris Agreement commits countries to limit global warming to well-below 2°C above pre-industrial levels, ideally following a more ambitious trajectory of 1.5°C. Scientists have calculated that in order to follow a 1.5°C trajectory, the world must cut its emissions in half by 2030 and reach net zero by 2050.
Ensure that the quantification of greenhouse gas emissions is systematically neither over nor under actual emissions as far as can be judged, and that uncertainties are reduced as far as practicable.
Data on the level of an activity that affects greenhouse gas emissions or sequestration. For example, it could be litres of fuel, kilograms of textile, etc. In carbon accounting, activity data generally allows for more accurate emissions estimates.
A criterion for assessing whether a project has resulted in greenhouse gas emission reductions or removals in addition to what would have occurred in its absence. A carbon removal project is additional if it will lead to a reduction of greenhouse gas emissions that would not have happened otherwise.

Capital goods are final products that have an extended life and are used by the company to manufacture a product; provide a service; or sell, store, and deliver merchandise.
Carbon accounting is the process of measuring how much carbon dioxide equivalents (CO2e) an organisation (company, state, etc.) emits.
Carbon dioxide is a colourless gas that occurs naturally in the atmosphere. It is also created in many industrial processes. Carbon dioxide is a greenhouse gas and therefore contributes to global warming.
Carbon Dioxide Equivalent
For any greenhouse gas, the carbon dioxide equivalent (CO2e) is the mass of CO2 which would warm the earth as much as the mass of that gas. CO2e provides a common scale for measuring the climate effects of all greenhouse gases.
Carbon Disclosure Project
CDP is a framework for companies, cities, and states to report their environmental impact.
All of the greenhouse gas emissions (both direct and indirect) associated with a specific product or activity.
A business is carbon negative (or climate positive) if the net result of its activities is a decrease in the amount of carbon in the atmosphere. This is going a step further than net zero.
A business is carbon neutral when its core business activities do not contribute any additional greenhouse gas emissions, on balance.
Carbon offsetting is the process of balancing a business’s carbon emissions by removing a proportionate amount of carbon from the atmosphere.
Carbon reduction is the process of reducing the amount of GHG emissions a company produces. This can be done by switching to more climate-friendly suppliers or to clean energy providers.
Carbon removal is the process of taking carbon from the atmosphere and storing it where it won’t contribute to climate change.
Carbon sequestration is the process of storing carbon somewhere where it won’t contribute to climate change.
A carbon sink is anything, natural or otherwise, that accumulates and stores some carbon-containing chemical compound for an indefinite period and thereby removes carbon dioxide from the atmosphere.
A commitment to reduce a company’s greenhouse gas emissions by a specified amount before a given year.
A tax on the carbon emissions required to produce goods and services. A carbon tax reduces emissions overall, both by decreasing demand for high-emission goods and services and by incentivising efforts to make them less emissions intensive.
Chlorofluorocarbons (CFCs) are nontoxic, non-flammable chemicals containing atoms of carbon, chlorine, and fluorine. CFCs are believed to be a major cause of stratospheric ozone depletion.

The release of greenhouse gases into the atmosphere.
A factor allowing greenhouse gas emissions to be estimated from a unit of available activity data (e.g. tonnes of fuel consumed, tonnes of product produced) and absolute GHG emissions.
Equity Share Approach
The equity share reflects economic interest, which is the extent of rights a company has to the risks and rewards flowing from an operation. Typically, the share of economic risks and rewards in an operation is aligned with the company's percentage ownership of that operation, and equity share will normally be the same as the ownership percentage.
The company has financial control over the operation if the company has the ability to direct the financial and operating policies of the operations with the view of gaining economic benefits.
Fossil fuel has been trapped underground for millennia. This contains fossilised animal and plant remains. Due to the origin of the fossilised particles, it has a high carbon content. Fossil fuel combustion produces CO2, water and energy.
Emissions that are not physically controlled but result from the intentional or unintentional releases of greenhouse gases. They commonly arise from the production, processing transmission storage and use of fuels and other chemicals, often through joints, seals, packing and gaskets.
Global Reporting Initiative
The Global Reporting Initiative provides a set of standards for companies to use when reporting their environmental impact. They provide both general best practices and industry-specific guidance.
Global Warming Potential
It is a measure of cumulative radiative force, which aims to quantify the long-term contribution of a gas to global warming. Each GHG has a specific GWP value and this is relative to a specified time period (typically 100 years, but values are also available for 20-year and 50-year time horizons).
The greenhouse effect relies on greenhouse gases to trap incoming solar radiation, allowing the planet to stay warm even when the sun isn't shining directly on us.
A greenhouse gas is a gas that absorbs and emits radiant energy within the thermal infrared range, causing the greenhouse effect and thereby global warming.
Greenhouse Gas Protocol
The Greenhouse Gas Protocol provides the most widely used greenhouse gas accounting standards. Their corporate accounting and reporting standard outlines requirements and guidance for companies, and serves as the basis for virtually every corporate reporting program in the world.
Greenwashing is the practice of providing misleading or false information about the sustainability of a company’s business activities. Because companies may not realise that majority of their emissions are in Scope 3, or that many carbon offsets are of dubious efficacy, greenwashing can happen unintentionally as well as intentionally.
Hydrofluorocarbons are a type of synthetic greenhouse gas, mostly used in refrigeration and air conditioning equipment. HFCs generally have a high global warming potential which means they have a greater ability to trap heat in the atmosphere compared to a similar mass of carbon dioxide.
The ISO 14064 is a specification with guidance at the organisation level on the quantification and reporting of greenhouse gas emissions and removals. The specification details how to design and develop a GHG inventory, and monitor and report on emission reductions.

Ozone-depleting substances include chlorofluorocarbons (CFCs), hydrochlorofluorocarbons (HCFCs), halons, methyl bromide, carbon tetrachloride, hydrobromofluorocarbons, chlorobromomethane, and methyl chloroform. Ozone-depleting substances are generally very stable in the troposphere and only degrade under intense ultraviolet light in the stratosphere.
The PAS 2060 is an initiative of the British Standards Institution and is a standard for carbon neutrality. The PAS 2060 requires that the total emissions at the end of a period be offset by carbon credits that must meet certain criteria.

The Science-based Targets initiative encourages companies to set science-based targets in line with the Paris Agreement. They provide general as well as industry-specific guidance on how to meet these targets.
Defines the operational boundaries in relation to indirect and direct greenhouse gas emissions.
Scope 1 emissions are direct greenhouse gas emissions that a company generates while performing its business activities. This includes stationary combustion, mobile combustion, fugitive emissions and physical and chemical processing.
Scope 2 emissions are the indirect emissions generated by the production of purchased energy.
Scope 3 emissions are all indirect emissions that occur in the value chain of a company and are not already included within Scope 2. These emissions are a consequence of the company’s business activities but occur from sources the company does not own or control.

The spend-based method of calculating greenhouse gas emissions takes the financial value of a purchased good or service and multiplies it by an emissions factor, resulting in an estimate of the emissions produced. Since spend-based methods’ emissions factors are built on the industry average greenhouse gas emissions levels, spend-based calculations can lack specificity.
