How do you convert to equivalent CO2?
By Gabriel Cooper
How do you convert to equivalent CO2?
Carbon dioxide (CO2) equivalent is a measure of how much a gas contributes to global warming, relative to carbon dioxide. You calculate the carbon dioxide equivalent of a quantity of F gas by multiplying the mass of the gas (in tonnes), by the gas’ global warming potential (GWP).
What is gtco2 eq yr?
– Total annual anthropogenic GHG emissions (GtCO2eq / yr) by groups of gases 1970 – 2010: CO2 from fossil fuel combustion and industrial processes; CO2 from Forestry and Other Land Use (FOLU); methane (CH4); nitrous oxide (N2O); fluorinated gases8 covered under the Kyoto Protocol (F-gases).
What are RCPs and the IPCC 5th Assessment Report?
Representative Concentration Pathways (RCPs) Four RCPs produced from Integrated Assessment Models were selected from the published literature and are used in the Fifth IPCC Assessment as a basis for the climate predictions and projections presented in WGI AR5 Chapters 11 to 14: RCP2.
How much carbon is in a ton of CO2?
The atomic weight of carbon is 12 atomic mass units, while the weight of carbon dioxide is 44, because it includes two oxygen atoms that each weigh 16. So, to switch from one to the other, use the formula: One ton of carbon equals 44/12 = 11/3 = 3.67 tons of carbon dioxide.
What is GT CO2e?
The greenhouse gas total are expressed in terms of billions of tonnes of global annual CO2 equivalent emissions (GtCO2e/year).
What is Gt CO2 eq?
Carbon dioxide equivalent (CO2eq) stands for a unit based on the global warming potential (GWP) of different greenhouse gases. The CO2eq unit measures the environmental impact of one tonne of these greenhouse gases in comparison to the impact of one tonne of CO2.
What does RCP8 5 stand for?
The RCP8. 5 combines assumptions about high population and relatively slow income growth with modest rates of technological change and energy intensity improvements, leading in the long term to high energy demand and GHG emissions in absence of climate change policies.
What does extremely likely mean the IPCC’s Fifth Assessment Report?
The atmosphere and ocean have warmed, the amounts of snow and ice have diminished, sea level has risen, and the concentrations of greenhouse gases have increased. … It is extremely likely that human influence has been the dominant cause of the observed warming since the mid-20th century.”
