How do I calculate the carbon footprint of a bank branch?
Add each branch's electricity at 0.710 kg CO2 per kWh, generator diesel at 2.68 kg per litre and AC refrigerant top-ups. Sum branches for the operational footprint. Loans and investments are a separate figure, financed emissions in Scope 3 Category 15, not part of the branch number.
Per branch
- Electricity from the branch bill, including ATMs on the same meter.
- Diesel for the generator.
- Refrigerant top-ups from AC service invoices.
Rented premises
Most branches are rented. If the bank runs the space and pays the bill, the electricity is Scope 2 under operational control.
Keep financed emissions apart
Emissions of borrowers and investee companies go in Category 15 under the PCAF method. Report them separately from the branch footprint.
Worked example: one branch (one month, illustrative inputs)
- Electricity: 3,500 kWh x 0.710 = 2,485 kg CO2
- Diesel: 150 litres x 2.68 = 402 kg CO2
- Branch total: 2,887 kg CO2 a month, 34.6 t a year
Inputs are illustrative; repeat for each branch from its own bills.
What Senseible does here
Senseible reads electricity bills (CEA grid factor 0.710 kg CO2 per kWh, CO2 Baseline Database version 21.0) and diesel, LPG and gas invoices (IPCC 2006 defaults) into a dated, fingerprinted Scope 1 and 2 record for each site. Intensity per unit uses the activity count you enter, and estimates are labelled as estimates.
