A new industrial facility or a modification at an existing plant may help the economy or bring new jobs. It could also cause an increase in emissions of GHGs in Minnesota. The Minnesota Pollution Control Agency (MPCA) now collects information on GHG emissions for some construction projects.
The MPCA developed an air permitting and environmental review initiative related to climate change pollutants. As part of this effort, the MPCA has begun to collect GHG data with certain air emission permit applications and environmental review submittals. This process requests that project proposers conduct and submit with their air permit application, a GHG emissions inventory for their proposed project. In addition, an evaluation to consider alternatives (fuel, energy efficiency, up/down stream operations) that may decrease overall GHG emissions may be requested on certain projects. A GHG evaluation may include:
- GHG emissions overview
- Fuels used
- Upstream and downstream factors that affect GHG emissions
- Alternatives that were considered
For information about when to do a GHG evaluation for air permits, visit MPCA's Air rulemaking webpage.
The MPCA is the Responsible Government Unit for environmental assessment worksheets (EAW) and environmental impact statements (EIS) for various types of projects. These include ethanol plants and manufacturing facilities, among others. Certain EAW projects should assess their emissions of GHGs. For an EIS, the scoping process will determine what information to include.
