Emissions - ENV-Linkages
The model incorporates several greenhouse gas (GHG) emissions. The standard database includes carbon emissions, methane (CH4), nitrous oxides (N2O) and an aggregate emissions bundle of fluoridated gases. The input data for carbon is in millions of metric tons of CO2 and the data for the other GHGs are both in physical units (metric tons) as well as in CO2-equivalent. The model allows for conversion between CO2e and Ce, i.e. carbon equivalent, depending on the needs of the user.
Emissions are generated by three sources: 1) direct consumption of a commodity; 2) factor-based emissions (e.g. capital, i.e. herds, in the livestock sectors); and 3) output or processed based emissions (e.g. methane from landfills). Carbon emissions in the current model version are only generated by the combustion of fossil fuels-coal, oil (crude and refined) and natural gas. Emissions of other GHGs can be a combination of all three sources of emissions. Emissions are based on the consumption level multiplied by the rate of emission per unit of consumption.

| Anticipation | The ENV-Linkages model is a recursive dynamic neo-classical general equilibrium model, meaning that decision-makers do not know the future when making a decision today. After it solves each period, the model then uses the resulting state of the world, including the consequences of decisions made in that period - such as resource depletion, capital stock retirements and installations, and changes to the landscape - and then moves to the next time step and performs the same exercise. |
