How to Calculate Scope 2 Emissions
Scope 2 emissions are indirect emissions from purchased energy that is generated off-site.

Formula
Scope 2 = (Electricity kWh * (1 - Renewable%) * Grid Factor + Steam MMBtu * 117) / 2,204.6
The grid emission factor varies by region. Purchasing renewable energy certificates (RECs) can reduce your Scope 2 under the market-based method.
Example Calculation
An office using 500,000 kWh/year at 0.92 lbs/kWh with 0% renewables and no steam.
- 01Grid electricity: 500,000 * (1 - 0) = 500,000 kWh
- 02Electricity CO2: 500,000 * 0.92 / 2,204.6 = 208.7 metric tons
- 03Steam CO2: 0 metric tons
- 04Total Scope 2: 208.7 metric tons CO2
