Carbon budgetA carbon budget can be defined as a tolerable quantity of greenhouse gas emissions that can be emitted in total over a specified time. The budget needs to be in line with what is scientifically required to keep global warming and thus climate change tolerable.Carbon budgeting is sometimes confused with the use of targets, thresholds or caps to set emissions reduction goals.
Carbon dioxide (CO2)Agas that occurs naturally in the atmosphere. It is produced when animals breathe, when vegetation rots, and when material containing carbon is burnt or broken down.
Carbon dioxide equivalent (CO2e)Carbon dioxide equivalent or CO2e is a term for describing different greenhouse gases (GHG) in a common unit. For any quantity and type of greenhouse gas, CO2e signifies the amount of CO2which would have the equivalent global warming impact. A quantity of GHG can be expressed as CO2e by multiplying the amount of the GHG by its global warming potential (GWP). For example, if 1kg of methane is emitted, this can be expressed as 25kg of CO2e (1kg CH4 X 25 = 25kg CO2e). CO2e is a useful term in that it allows collections of greenhouse gases to be expressed as a single number thereby allowing the comparison of different GHG collections. CO2e is also sometimes written as CO2eq, CO2equivalent or even CDE.
Carbon pricingCarbon pricing is an approach to reducing greenhouse gas (GHG) emissions that uses market mechanisms to pass the cost of emitting on to emitters. Its broad goal is to discourage the use of carbon dioxide–emitting fossil fuels. A key aspect of carbon pricing is the polluter paysprinciple. By putting a price on carbon, society can hold emitters responsible for the costs of adding GHG emissions to the atmosphere, these costs include polluted air and the costs associated with all of the impacts of climate change. Putting an appropriate price on carbon creates financial incentives for polluters to reduce emissions.
Carbon sequestrationThe long-term storage of carbon in plants, soils, geologic formations, and the ocean. Carbon sequestration occurs both naturally and as a result of anthropogenic activities and typically refers to the storage of carbon that has the immediate potential to become carbon dioxide gas. In response to growing concerns about climate change resulting from increased carbon dioxide concentrations in the atmosphere, considerable interest has been drawn to the possibility of increasing the rate of carbon sequestration through changes in land use and forestry and also through geoengineering techniques such as carbon capture and storage.
