Total Scope 2 Emissions vs Annual Electricity Use
Formula
## 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.
Esempio Risolto
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
Domande Frequenti
What is the difference between location-based and market-based Scope 2?
Location-based uses your regional grid average emission factor. Market-based accounts for renewable energy purchases, RECs, and power purchase agreements, often resulting in lower reported emissions.
How do I find my grid emission factor?
The EPA eGRID database provides emission factors by US region. The IEA provides international factors. Your utility may also publish their specific generation mix.
Can I achieve zero Scope 2 emissions?
Yes, by purchasing 100% renewable electricity through RECs, green tariffs, or on-site generation. Many companies have achieved this under the RE100 initiative.
