Being a Net Zero, the act of directly reducing any greenhouse gas (GHG) emissions, such as carbon dioxide (CO2) and other GHGs like methane (CH4), nitrous oxide (N2O), and hydrofluorocarbons (which tend to trap more heat than CO2), is known as emissions reduction. Purchasing "carbon sinks," such as tree planting, soil carbon management, biochar, and direct air carbon capture and storage, is necessary to remove carbon dioxide from the atmosphere. To offset its remaining carbon footprint, an organization must purchase carbon credits produced by emissions reduction or removal enhancement programs carried out by another organization. Do carbon neutrality and net zero interchanges? Businesses that claim to be "carbon neutral" have calculated their carbon footprint, reduced it through GHG emissions reductions and removals, and then offset the remaining portion of their footprint.
