Greenhouse Gases

Internal Table Name: GreenhouseGases

The greenhouse gases table is responsible for storing the overall carbon constraints for any supply chain model.

Maximum Carbon Footprint

Technology: NO

Table: GreenhouseGases

Internal Name: MaxCarbonFootprint

Type: Short Text (50)

Defines the maximum carbon footprint allowed in any model run. This is enforced by solving the model with this number as a hard constraint on output. This number is compared to the total CO2 of any model. Enter a value, then optionally select a weight unit of measure. If you do not select a unit of measure, the default Weight Unit Of Measure from Model Settings is used.

Enforce Max Carbon Footprint

Technology: NO

Table: GreenhouseGases

Internal Name: EnforceMaxCarbonFootprint

Type: Bit

One of Yes, No. (Actual database values are 1,0.)

Defines whether or not the Max Carbon Footprint value is used as a hard constraint. If blank or set to No, the constraint is excluded from the mixed integer linear program used to optimize the model.

Default: No

Carbon Cost

Technology: NO

Table: GreenhouseGases

Internal Name: CarbonCost

Type: Short Text (50)

Represents cost per unit of CO2 in the model. This field is used to model carbon taxation and other penalties for carbon emissions.

Carbon Offset Price

Technology: NO

Table: GreenhouseGases

Internal Name: CarbonOffsetPrice

Type: Short Text (50)

Cost per unit of carbon offsets that can be purchased. In the real world, this price is the equivalent to the cost of a carbon credit, or could represent a cost for voluntary carbon offsetting.

Optimize Carbon Offset

Technology: NO

Table: GreenhouseGases

Internal Name: OptimizeCarbonOffset

Type: Bit

One of Yes, No. (Actual database values are 1,0.)

Defines whether or not the number of carbon offsets needed for purchase should be included in the objective function of the network design optimization.

Default: No

Initial Carbon Offsets

Technology: NO

Table: GreenhouseGases

Internal Name: CarbonOffsetInitial

Type: Short Text (50)

The initial number of units of carbon offsets included in the model. The number of additional carbon offsets needed in the model is calculated by subtracting the initial quantity of carbon offsets from the total number of carbon offsets needed to meet the necessary requirements of the supply chain network.

The initial carbon offset is not part of the CO2 optimization; therefore, no cost for these initial units is included in the Total CO2 Cost.

Minimum Carbon Offsets

Technology: NO

Table: GreenhouseGases

Internal Name: CarbonOffsetMinimum

Type: Short Text (50)

The minimum number of carbon offsets that must be purchased.

Maximum Carbon Offsets

Technology: NO

Table: GreenhouseGases

Internal Name: CarbonOffsetMaximum

Type: Short Text (50)

The maximum number of carbon offsets that can be purchased for the network design.
