How to Calculate Scope 2 Emissions

Scope 2 emissions are indirect emissions from purchased energy that is generated off-site.

Sources

  • Purchased electricity
  • Purchased steam, heat, or cooling

    • 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.

    计算示例

    An office using 500,000 kWh/year at 0.92 lbs/kWh with 0% renewables and no steam.

    1. Grid electricity: 500,000 * (1 - 0) = 500,000 kWh
    2. Electricity CO2: 500,000 * 0.92 / 2,204.6 = 208.7 metric tons
    3. Steam CO2: 0 metric tons
    4. Total Scope 2: 208.7 metric tons CO2
