State Inventory and Projection Tool
EPA's State Inventory and Projection Tool is an interactive spreadsheet model designed to help states develop GHG emissions inventories. The tool has two components: the state inventory tool and the projection tool.
The State Inventory Tool (SIT) gives users the option of applying their own state-specific data or using default data pre-loaded for each state. The default data are gathered by federal agencies and other sources covering fossil fuels, agriculture, forestry, waste management, and industry. SIT provides a streamlined way to update an existing inventory or complete a new inventory.
The Projection Tool allows users to create a simple forecast of emissions through 2020 based on historical emissions and projections of future energy consumption, population, and economic factors.

About the Tool
The State Inventory Tool is a top-down approach to calculating estimates of greenhouse gas emissions at the state level. This means:
- It looks at direct emissions only—for example, tons of coal burned times an emissions factor. It does not calculate emissions from any indirect sources such as offsite waste disposal or electricity consumption.
- It gives an aggregated total for each sector at the state level, and does not include emissions for specific power plants, industrial facilities, or other point sources.
The state inventory tool contains methods and data that are specific to U.S. states and may not be appropriate for scales other than the state level or for countries other than the U.S.
The methods used and the sectors covered are the same as those in the U.S. GHG Inventory.
