Thousands of chemicals are emitted into the air. Many of these are air pollutants that can directly or indirectly affect human health, reduce visibility, cause property damage and harm the environment. For these reasons, the Minnesota Pollution Control Agency attempts to reduce the amount of pollutants released into the air. In order to understand the sources of air pollution and track the success of reduction strategies, the MPCA collects data and analyzes the emissions of certain air pollutants.

How much pollution is being emitted into Minnesota’s air and water? Is pollution increasing or decreasing? Where is it coming from? Every two years, MPCA reports on the amount of water and air pollution in the state. The 2018 Pollution Report also provides more information on air and water pollutants, greenhouse gas emissions, and emerging contaminants of concern.
In recent years, both the MPCA and EPA have increased focus on reducing mercury air emissions. Both Minnesota and EPA require mercury reductions from power plants. Additionally, the MPCA developed a plan to meet water-quality standards by reducing mercury emissions released into the air. Despite significant mercury reductions from some sectors, the MPCA projects it will not meet the 2025 statewide mercury emissions reduction goal. Emissions from the Products sector category are holding steady or even increasing. Products that contain mercury include fluorescent lights, certain switches, thermometers, and “silver” dental fillings, among others. The MPCA is working to improve the accuracy of its estimates for these uses to better inform reduction strategies.

Every two years, the Minnesota Pollution Control Agency (MPCA) reports to the state Legislature the best estimate of the total volume of water and air pollution that was emitted in the state for the years for which data are available. This report was first produced in 1996 and since then it has evolved to include new kinds of information such as discharges of toxic air pollutants, greenhouse gas emissions and issues of concern.
Pollution Report: 2016 report to Legislature
Annual emissions and discharge estimates are an important component of tracking progress on reducing air and water pollution and understanding the relative contributions of pollution sources. In the 2016 report, the MPCA reports on the 2012 MPCA Greenhouse Gas Inventory, the 2011 and 2014 Minnesota Criteria Pollutant Air Emission Inventories, the 2011 Air Toxics Emission Inventory and the 2000 to 2015 Water Quality National Pollutant Discharge Elimination System (NPDES) Discharge Monitoring Reports and Water and Soil Resources eLINK database.
