State Greenhouse Gas Emissions Inventory
Greenhouse gas (GHG) emissions inventories report the major sources and activities responsible for emitting GHGs throughout a state in a given year. Commonly reported greenhouse gases include carbon dioxide (CO2), methane (CH4), and nitrogen oxide (N2O).
A state’s total emissions are often further broken down by sectors, such as electricity, transportation, and industry, which are reported to highlight the biggest sources of emissions. Inventories also include historical emissions, typically the baseline year of a state’s GHG emissions reduction target, which allows a state to see where progress has been made and where additional measures are needed. In addition to sector breakdowns, some inventories include data on emissions gas type and fuel type in each sector and source.
