Carbon accounting, also known as greenhouse gas (GHG) accounting, is the process used by organizations to measure the amounts of carbon dioxide equivalents (CO2e) emitted directly and indirectly by their activities.
Carbon Credit
Carbon credits represent the removal of one tonne of carbon dioxide or an equivalent amount of a different greenhouse gas from the atmosphere. These are from verified and measured emissions reductions from certified emissions reduction or removal projects. These allow the owner to emit a specific amount of carbon dioxide or the equivalent of other GHGs.
Carbon Emissions
Carbon emissions refer primarily to the release of carbon dioxide (CO2) into the atmosphere. Carbon emissions can also include other carbon-based greenhouse gasses such as methane (CH4), but CO2 is by far the most prevalent and is often used synonymously with carbon emissions.
Carbon Markets
Carbon markets are systems through which countries, organizations, or individuals buy and sell credits for greenhouse gas (GHG) emissions, specifically carbon dioxide (CO2) and other GHG emissions measured in terms of carbon dioxide equivalents (CO2e). Each credit represents the removal of one tonne of carbon dioxide or an equivalent amount of a different greenhouse gas from the atmosphere.
Carbon Neutrality
Carbon neutrality refers to achieving a net-zero carbon footprint by balancing the amount of carbon dioxide (CO2) released into the atmosphere with an equivalent amount of CO2 removed or offset.
Corporate Sustainability Due Diligence
