↑Global Carbon Project (2022)[2] The rate of build-up of carbon dioxide (Samfuri:CO2) in the atmosphere can be reduced by taking advantage of the fact that atmospheric Samfuri:CO2 can accumulate as carbon in vegetation and soils in terrestrial ecosystems. Under the United Nations Framework Convention on Climate Change any process, activity or mechanism which removes a greenhouse gas (GHG) from the atmosphere is referred to as a "sink". Human activities impact terrestrial sinks, through land use, land-use change and forestry (LULUCF), consequently, the exchange of Samfuri:CO2 (carbon cycle) between the terrestrial biosphere and the atmosphere is altered.[3]
↑Greenhouse gases (GHG) constitute a group of gases contributing to global warming and climate change.
The Kyoto Protocol, an environmental agreement adopted by many of the parties to the United Nations Framework Convention on Climate Change (UNFCCC) in 1997 to curb global warming, nowadays covers seven greenhouse gases:
the non-fluorinated gases:
carbon dioxide (CO2),
methane (CH4),
nitrous oxide (N2O),
the fluorinated gases:
hydrofluorocarbons (HFCs),
perfluorocarbons (PFCs),
sulphur hexafluoride (SF6),
nitrogen trifluoride (NF3).
Converting them to carbon dioxide (or Samfuri:CO2) equivalents makes it possible to compare them and to determine their individual and total contributions to global warming.
