Can be set as a target for all greenhouse gases or for CO2 only. Defined by the Paris Agreement as a balance between anthropogenic emissions by sources and removals by sinks of GHG. Note that Carbon Neutral means having a net zero carbon footprint; achieving net zero carbon emissions by balancing a measured amount of carbon released (by a company, product, or activity) with an equivalent amount sequestered or offset, or buying enough carbon credits to make up the difference.
