Emissions Inventory Program

The Emissions Inventory Program is responsible for compiling data on the release of air pollutants. The Emissions Inventory Program uses a variety of data sources and statistical modeling to calculate emissions from stationary sources (factories and homes), mobile sources (cars, trains, etc.), and biogenic sources (vegetation and soils).  The periodic compilation of the air pollutant emissions data is called an inventory.  For data compilation purposes, air pollutants are divided into three broad categories: criteria pollutants, hazardous air pollutants (also known as air toxics), and greenhouse gases.  This section is designed both to assist facilities in Maine with the collection and submission of air pollutant emission data and to disseminate information to the public about what those emissions mean for their health and the environment.

Emissions Inventory Information

Criteria Pollutants provides information about the criteria pollutants and information for businesses on reporting criteria pollutant emissions.

Greenhouse Gases provides greenhouse gas calculation tools and other information about calculating and reporting greenhouse gas emissions.

Hazardous Air Pollutants provides information about reporting emissions of hazardous air pollutants.

i-STEPS is the software used by the Emissions Inventory Program to collect data on criteria pollutant emissions.  This site contains information on obtaining and using the software.

List Servers provides information about both the Department of Environmental Protection and U.S. EPA list servers used to disseminate emissions inventory information to businesses and improve reporting and compliance.

How do I find out about air emissions near my home? is the starting point for citizens interested in learning more about air pollution in their state and county.
