What is a A greenhouse gas inventory? The EPA Says....

A greenhouse gas inventory is an accounting of the amount of greenhouse gases emitted to or removed from the atmosphere over a specific period of time (e.g., one year).

A greenhouse gas inventory also provides information on the activities that cause emissions and removals, as well as background on the methods used to make the calculations.

Policy makers use greenhouse gas inventories to track emission trends, develop strategies and policies and assess progress.

Scientists use greenhouse gas inventories as inputs to atmospheric and economic models.

To track the national trend in emissions and removals since 1990, EPA develops the official U.S. greenhouse gas inventory each year.

The national greenhouse gas inventory is submitted to the United Nations in accordance with the Framework Convention on Climate Change.
