Emissions Calculator

This chapter provides detailed information about the Greenhouse Gas Emissions Calculator.

Calculation of Global Warming Potential (GWP)

The application helps banks and financial institutions calculate GHG emissions based on the 100-year Global Warming Potential (GWP) of the following greenhouse gases by using the various synthesis reports published by the Intergovernmental Panel on Climate Change (IPCC) - AR4, AR5 and AR6. This calculation is applicable to all emission categories of Scope 1, 2 and 3, wherever an emission factor is required.

Note:

This has to be calculated only for those records where we do not necessarily do not compute individual/disaggregated values for each of these gases (i.e. emission factors not available for these).
  1. CH4
  2. N20
  3. HFCs
  4. PFCs
  5. SF6
  6. NF3

Pre-built Model/Infrastructure for Emission Factor Database Sources

The application is pre-equipped to support the usage of various emission factor database sources and/or emission factors from various vendors or data providers. As part of this functionality, the solution has pre-seeded these data elements across various database sources in form of hierarchies. Below is a list of emission factor database sources for which hierarchies are pre-seeded in the application across available emission categories.
Emission Factor Database/Source
UNFCC
DEFRA
EPA
GHG Protocol
PCAF
IFI

Emission Intensity Metrics

Application supports calculation of below set of emission intensity metrics as part of the overall package within Emissions Calculator. These are based on the PCAF Global GHG Accounting & Reporting Standard.
  1. Weighted average carbon intensity (WACI): Objective is to understand the exposure to emission intensive companies expressed as tCO2 e/€M or $M of reporting company’s investee or counterparty revenue.
  2. Economic emission Intensity: Objective is to understand how the emission intensities of different portfolios (or parts of portfolios) compare to each other per monetary unit. It is expressed as tCO2 e/€M or tCO2 e/$M loaned or invested by the reporting company.
  3. Production emission Intensity: Objective is to understand the efficiency of a portfolio (or parts of a portfolio) in terms of total GHG emissions per unit of a common output. It is expressed as tCO2 e/MWh, tCO2 e/tonne product produced by the reporting company’s investee or counterparty.
  4. Consumption emission Intensity: Objective is to understand the efficiency of a portfolio (or parts of a portfolio) in terms of total GHG emissions per unit of a common output. It is expressed as units of product consumed by the reporting company’s investee or counterparty.
