Emission parameters
These parameters define emissions in a scenario, including emission intensities of technology activity, exogenous emissions, emission limits, and emission penalties.
Annual emission limit
Maximum emissions allowed in the specified year.

Emissions activity ratio
Emission factor for the indicated technology and mode.
Emission factors can be negative, and if you specify a negative emission factor for a pollutant with an externality cost, your scenario may result in negative emission penalties. In this case, you may need to constrain the associated technology's operation to avoid an unbounded (infeasible) optimization problem. For example, if a technology can generate negative emissions of a pollutant with an externality cost, the cost of building and running the technology is lower than the externality value, and there are no limits on the technology's deployment and use, the optimization problem will be unbounded.
