Carbon budget
The total amount of carbon dioxide (CO2) emissions that can be released over a
period of time while still remaining below a certain global temperature average. Also
refers to the balance of incomes and losses between carbon sinks in the carbon
cycle. Also see Sequestration.
Carbon dioxide equivalent
A metric measurement used to compare the emissions from greenhouse gases other
than CO2 on the basis of their global-warming potential (GWP). Amounts of other
gases are converted to the equivalent amount of carbon dioxide with the same global
warming potential.
Carbon dioxide capture and storage (CCS)
A process in which carbon dioxide (CO2) from industrial and energy-related sources
is separated (captured), conditioned, compressed and transported to a long-term
storage location to be isolated from the atmosphere.
Carbon intensity
The amount of carbon dioxide (CO2) emissions that is released per unit of another
variable like gross domestic product (GDP) or transport. This tells us how carbon
intensive the variable is.
Carbon neutrality
See Net zero CO2 emissions.
Carbon price
The price for prevented or released carbon dioxide (CO2) or CO2-equivalent
emissions. It may refer to the rate of a carbon tax or the price of emission permits.
Often, carbon prices are used as a representative of the level of effort in mitigation
policies.
