EPA greenhouse gas reporting and emission rates
The U.S. Environmental Protection Agency’s (EPA’s) mandatory national greenhouse gas (GHG) reporting program requires regulated natural gas utilities, and some of their largest customers, to report GHG emissions from their operations. The EPA website includes resources to understand the rule and an online tool to see if it applies to your company.
Electric utility energy mix and emission rates
This electric energy mix and emission rate information is provided for retail electric customers of Upper Michigan Energy Resources Corporation (UMERC), a regulated utility subsidiary of WEC Energy Group (WEC) operating in the state of Michigan. The emission rates are supplied for customers to estimate their environmental footprint from electric energy supplied by UMERC, such as Scope 2 (indirect) greenhouse gas emissions.
Emission rates are calculated using total emissions and megawatt-hours from generation by owned facilities. The emission rates apply to UMERC’s retail electric utility customers, except for customers of Energy for Tomorrow® or NatureWise®, renewable energy programs that are offered to UMERC’s retail electric customers.
Emissions from electric generation facilities are calculated in accordance with the U.S. Environmental Protection Agency mandatory Greenhouse Gas Reporting Program regulations under 40 CFR Part 98. The energy resource mix represents net generation from UMERC-owned facilities.
WEC and UMERC reserve the right to use all or some of the environmental attributes associated with generation from renewable energy sources in future years to comply with renewable energy standards or other regulatory requirements, or to sell to third parties the environmental attributes such as renewable energy credits, offsets, allowances and the avoided emissions of greenhouse gases. All information is provided on a voluntary basis, could be subject to change, and has not received independent third party verification. Neither WEC nor UMERC makes any assurances regarding the use of this information by external parties for marketing or other sustainability claims.

Information about the natural gas delivered by Upper Michigan Energy Resources
If your company is required to report greenhouse gas emissions or chooses to analyze its carbon footprint, you may need information about natural gas delivered by Upper Michigan Energy Resources. The EPA’s default emission factors for natural gas for CO2 and CH4 and N2O are appropriate to use for the natural gas we distribute along with WEC Energy Group’s leak rate of 0.55 kg/mmBTU. The amount of natural gas consumed can be found on your bill or in the My Account (We Energies or Wisconsin Public Service) section of the website. As a service to customers, we provide the heating value of your natural gas below*.
