Calculate your Emissions
Calculating a company’s emissions data is crucial for several reasons. First and foremost, it allows organizations to understand their environmental impact and identify areas where they can reduce their carbon footprint. By quantifying emissions from various sources such as energy consumption, transportation, and production processes, companies can set meaningful sustainability goals and track their progress over time.
Calculate CO₂ output emission factor
Step 1: Visit the Environmental Protection Agency's eGRID map at this link: https://www.epa.gov/egrid/data-explorer
A blue U.S. map will display once the page loads.
Step 2: On the eGrid page, there are 5 fields across the top. Only the last dropdown field should be changed: this is the applicable year you're calculating for. Select the year by using the dropdown.
Step 3: On the eGrid map, find the region associated with your geography, ISO, or zip code. If you need to look up a region by zip code, please refer to this EPA chart (link opens in new tab).
Step 4: With your mouse, hover or click on the region in the eGrid map, the emission factor will display in the pop-up and will also be highlighted in the chart on the right (other numbers will be greyed out). The number associated with the region is the total CO₂ ouput emission factor for all fuel types in the region.
FAQs
Does ENGIE offer certification for the emission factor?
No, the emission factor is regulated by the U.S. Environmental Protection Agency.
Additional information
eGrid manages the online tool and the most recent data available is for 2022.
Subregions, unlike states, are defined using the transmission, distribution and utility service territories of power plants and therefore don’t follow traditional geographic state boundaries. For example, the subregion of WECC Northwest includes all or part of the following states: California, Idaho, Montana, Nevada, Oregon, Utah, Washington, and Wyoming.
