GHG computational method
Organizational boundaries
Reported greenhouse gas emissions are an outcome of activity data collected from 11 locations in India as well as other international offices in Argentina, China, UK, Poland and the USA that are under the operational control of CRISIL Limited. The reporting period of this inventory is calendar year 2023.
The emission calculation includes Scope 1, 2, and 3 emissions from all relevant Kyoto Protocol gases. The below sources of emission have been included in the scope of this inventory.
Scope 1 emissions: these are direct emissions resulting within an organization’s boundary and arise from sources that the organization owns or controls. In the case of this inventory, the scope 1 sources include natural gas combustion, fuel combustion, fugitive emissions of refrigerants, combustion of fuels in backup generators.
Scope 2 emissions: these are indirect emissions from the electricity that is used by the organization and is outside the organization’s boundary.
Scope 3 emissions: this includes all other indirect emissions that occur outside the organization but are a result of the activities related to the organization. In the case of this inventory, the scope 3 sources include business travel (via road, rail, and air), hotel stay, paper and work from home provision for employees.
Data computational methods
An independent GHG inventory has been developed for all the locations under CRISIL Limited. A detailed discussion conducted with representatives from CRISIL to understand the operational boundary and identification of sources of GHG emissions. After the discussion, the data for these identified activities resulting in scope 1, 2, and 3 captured for calculation.
Provided below is the general process of activity data collection and source of respective emission factors that have been used for the calculation:
Stationary combustion: The total annual quantity of high-speed diesel (fuel) used by diesel generators (Diesel used is owned DG set which is part of scope 1 and shared DG sets which are part of scope 3) was captured and used for the emissions calculation. The emissions factor for the calculation were derived from the IPCC 5th Assessment ReportforCO2,CH4,andN2O.Similarly,TheGlobalWarmingPotentials (GWP) were sourced from the IPCC 5th Assessment Report for CO2, CH4, and N2O. In certain cases where the total amount spent on the purchase of HSD is available, instead of the quantity consumed, the annual average price of HSD is per liter for 2023 has been taken from the Ministry of Petroleum & Natural Gas, Government of India (ppac. gov.in) to obtain the total quantity of HSD consumed.
Mobile emissions: The total annual quantity of fuel consumed in company-owned vehicles accounting for scope 1 as well as fuel used for employee commute and business travel via road accounting to scope 3, were captured and used for the emission calculation. The emissions factor for diesel was sourced from the IPCC 5th Assessment
ReportforCO2,CH4,andN2O.Similarly,TheGlobalWarmingPotentials (GWP) were sourced from the IPCC 5th Assessment Report for CO2, CH4, and N2O. In certain cases where the total amount spent on the purchase of HSD, petrol and CNG available, instead of the quantity consumed, the annual average price of HSD or petrol per liter and CNG per kilogram for 2023 was taken from the Ministry of Petroleum & Natural Gas, Government of India (ppac.gov.in) to obtain the total quantity of respective fuel consumption. The emission factors for petrol and CNG have been sourced from DEFRA 2023.
If fuel consumption from mobile sources is given in amount spent
∑ Total Amount Spent on Diesel Consumption (in INR) x Average INR of Diesel in 2023 x Liter to kg conversion x Net calorific value x Emission factor – IPCC (CO2, CH4 and N2O) = Total mobile emissions
∑ Total Amount Spent on CNG Consumption (in INR) x Average INR of CNG in 2023 x Emission factor (DEFRA) = Total mobile emissions
∑ Total Amount Spent on Petrol Consumption (in INR) x Average INR of Petrol in 2023 x Emission factor (DEFRA) = Total mobile emissions
∑ Emissions for 1 km = Power *Emission factor (CEA Grid) Where, Power = Battery of Electric vehicles (in MWh) / Mileage (in Kms)
If fuel consumption from mobile sources is given in liters/kgs of fuel
Fugitive emissions: The quantity of refrigerants based on the monthly top-up on air conditioning equipment. The emissions factors were sourced from the UK Department for Environment, Food and Rural Affairs, 2023 (DEFRA-2023).
Gaseous fuels LPG emissions: The quantity of LPG used in office locations was captured and used for the calculation of emissions. The emissions factors were sourced from the UK Department for Environment, Food and Rural Affairs, 2023 (DEFRA-2023).
If fuel consumption from provided in Kgs
If fuel consumption provided in amount spent
Emissions from electricity consumed: The total electricity consumed in kWh was collected for each of the buildings in the target locations. The corresponding location wise grid emission factors were sourced from the websites and publications of base countries (India: CEA grid emission factor report, UK: 2023 Government Greenhouse Gas Conversion Factors for Company Reporting, USA: EPA database, Argentina: IGES database, China: IGES database)
∑Total Diesel, Petrol, or CNG consumption (in liters) x Emission factor (DEFRA/IPCC) = Total mobile emissions
∑Total refrigerants top – up in buildings (in kg) x Net calorific value x Emission factor (CO2, CH4 and N2O) = Total fugitive emissions
∑Total LPG consumption (in kg) x Net calorific value x Emission factor (CO2, CH4 and N2O) = Total LPG emissionss
∑Total LPG consumption (in INR) x Average INR to kg conversion based on commercial LPG prices in 2021 x Net calorific value x Emission factor (CO2, CH4 and N2O) = Total LPG emissions
∑Total Diesel Consumption (in liters) x Liter to kg conversion x Net Calorific Value x Emission factor (CO2, CH4 and N2O) = Total Emissions from DG sets owned in buildings
