Total GHG Emissions Calculation

This is one of the core processing functions. You use this function to define the functions that calculate the emissions. The emission factors used in the calculations need to be updated and are a key part of the overall project calculation.

It consists of the following functions:

Collect Emissions Source Data

This Join function is used to combine the corporate master data with emissions source data.

The following model tables are joined:

  • Facilities Consumption Inventory

  • Travel Consumption Inventory

  • Vehicles Consumption Inventory

  • Waste Processing

  • Goods and Services

Derive GHG Scopes

This Derivation function is used to assign to the Collect Emissions Source Data corresponding values of the fields GHG Scope, Effect, Effect Value, Effect Unit and if necessary, Consumption Measure, Consumption and Consumption Unit. The emission sources are associated to their corresponding Scopes, that is, Scope 1, 2 and 3. They are based on the source they come from, that is, Facilities, Travel, Electricity, Vehicles, Purchased Goods, Waste, Processing and Use of Sold Goods.

Allocate Consumption Across Types

This Allocation function is used to allocate the effect value and/or consumption from the Derive GHG Scopes function according to the emission factor or energy source portion from the Emission Factors Model Table.

Calculate Emissions

This Calculation unit is used to calculate the emissions from all activities based on the calculation methodology pursuant to the GHG Protocol Corporate and Value Chain Standard. It uses the Allocate Consumption Across Types function as input for the calculation.

Allocate Transmission and Distribution Losses

This Allocation function allocates the transmission and distribution losses in electricity to the Calculate Emissions function for purchased electricity.

Join Total Emissions

This Join function is used to calculate the total emissions after joining the data from the following functions:

  • Calculate Emissions

  • Allocate Transmission and Distribution Loss

Calculate Near-Term Yearly Targets

This View function uses the Corporate Baseline and Target function as input to calculate the percentage reduction for the near-term targets.

The outputs include:

  • Target Year

  • Target Reduction [%] compared to baseline year

Prepare Long-Term Target Calculation

This Join function uses the Corporate Baseline and Target function as input to calculate the percentage reduction for the long-term targets from 2031 until 2050. It shows the long term:

  • Target Year

  • Target Reduction [%] compared to baseline year (2020)

Calculate Long-Term Yearly Targets

This View function uses the Prepare Long-Term Target Calculations function as input to view the long-term target type. It shows the long term:

  • Target Year

  • Target Reduction [%] compared to baseline year

Join Near-Term and Long-Term Targets

This Join function calculates and unifies the target emissions as follows:

  • Using the Near-Term Science-Based Targets, the function calculates the target emissions for the years associated with near-term targets.

  • Using the Long-Term Science-Based Targets, the function calculates the target emissions for the years associated with long-term targets.

Join Final Impact with Targets

This Join function calculates the offset emissions by joining the Join Near-Term and Long-Term Targets with the Join Total Emissions to provide the final environmental impact results as well as the targets.
