How to Use Texas's Emission Factor for Scope 2 Reporting

For GHG Protocol Scope 2 location-based emissions reporting, multiply each facility's electricity consumption by the emission factor for its ZIP code's eGRID subregion. Facilities in different parts of Texas may be in different subregions - use the API to get the exact factor by ZIP code.
