Calculate Environmental KPIs

This section defines functions that calculate the environmental KPIs.

It comprises the following functions:

Collect Emissions Source Data

This Join function is used to combine the Corporate Master Data with the following sustainability data sources for the ESG Area = “ENV” (Environment):

  • Facilities Consumption Inventory

  • Travel Consumption Inventory

  • Vehicles Consumption Inventory

  • Goods and Services Inventory

  • Waste Management

  • Financial Instruments Data

  • Distributor Data

  • Facilities Location Data

Derive GHG Scopes

This Derivation function is used to assign the corresponding values of the following fields to the results of the Collection Emissions Source Data function:
  • GHG Scope
  • Effect
  • Effect Value
  • Effect Unit
  • Consumption Measure (if necessary)
  • Consumption (if necessary)
  • Consumption Unit (if necessary)
The emission sources are associated to their corresponding scopes (namely Scope 1, 2 and 3), and based on the source they come from (namely Facilities, Travel, Electricity, Vehicles, Purchased Goods, Waste, Processing and Use of Sold Goods, Distributors, and Investments).

Allocate Consumption Across Types

This Allocation function is used to allocate consumption values from the Derive GHG Scopes function to the Emission Factors function based on the distribution types of the consumption measures. Both consumption and effect values are allocated. This function also calculates the emission factors for all activities as per the methodology pursuant to the GHG Protocol Corporate and Value Chain Standard, using the following formula:

The following list describes the formula in detail:

  • CONVF – Emission Factor

  • CO2F – Carbon Dioxide Factor

  • GWP_CO2 – Global Warming Potential of Carbon Dioxide

  • CH4F – Methane Factor

  • GWP_CH4 – Global Warming Potential of Methane

  • N2OF – Nitrous Oxide Factor

  • GWP_N2O – Global Warming Potential of Nitrous Oxide

Calculate Emissions

This Calculation Unit function is used to calculate emissions from all the 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.

This function contains of the following rules:

  • R0001 – Location and Market Based: Map the effect value and consumption to location and market-based emission factors for calculation method MB and LB

  • R0002 – GHG Emissions: Calculate emissions using the following formula: Emissions = Consumption × Emission Factor

  • R0003 – GHG Emissions for Scope 3 Category 15: Include Scope 3 Category 15 data

Calculate Biogenic Emissions

This Calculation Unit function is used to calculate emissions from all biogenic sources, such as ethanol and biodiesel, based on the calculation methodology pursuant to the GHG Protocol Corporate and Value Chain Standard. It uses the Calculate Emissions function as input for calculation.

This function calculates the emissions of the biogenic activities as per the formula: Emissions = Consumption × Emission Factor × Heating Value

There are the following rules in this function:

  • R0001 – Biogenic Scope 1

  • R0002 – Biogenic Scope 3

Allocate Transmission and Distribution Losses

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

Total Emissions

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

  • Calculate Emissions

  • Calculate Biogenic Emissions

  • Allocate Transmission and Distribution Loss

  • Water Use Data
