- Title
- Michigan Statewide Greenhouse Gas Inventory [Michigan]
- Description
- This dataset represents the State of Michigan's statewide greenhouse gas inventory covering the years 2005-2021. The dataset aggregates greenhouse gas emissions across major economic sectors and is used to support data visualization through the Michigan Greenhouse Gas Inventory dashboard. The inventory tracks economy-wide emissions trends and provides sector-level totals to help understand how emissions have changed relative to the 2005 baseline year, which is the reference year used in the MI Healthy Climate Plan . For questions regarding this data, please reach out to the Office of Climate and Energy at EGLE-OCE@Michigan.gov . What the dataset shows The dataset includes annual emissions estimates for the following economic sectors: Electric Power: Emissions from electricity generation, including fuel combustion and transmission and distribution (T&D) system losses. Transportation: Emissions from on-road and non-road vehicles, including fuel combustion by vehicle type. Residential and Commercial Buildings: Emissions from fuel combustion in homes and commercial buildings, including space heating, water heating, and cooking. Industry: Emissions from industrial fuel combustion, manufacturing processes, and natural gas and oil systems. Agriculture: Emissions from enteric fermentation, manure management, agricultural soil management, and liming and urea application. Waste and Wastewater: Emissions from landfills, municipal and industrial wastewater treatment, and related waste management processes. Natural and Working Lands: Emissions and carbon removals from forests, wetlands, settlements, flooded lands, harvested wood products, and agricultural soil carbon. Emissions are reported in million metric tons of carbon dioxide equivalent (MMTCO₂e) and represent the combined impact of multiple greenhouse gases. Greenhouse gases included The dataset includes emissions from the following greenhouse gases: Carbon dioxide (CO₂) Methane (CH₄) Nitrous oxide (N₂O) Hydrofluorocarbons (HFCs) Perfluorocarbons (PFCs) Sulfur hexafluoride (SF₆) Attribute Fields and Descriptions Field Name Description Year Calendar year of the emissions estimate (2005-2021). Sector A broad economic category used to group emissions sources. Values include: Electric Power, Transportation, Residential and Commercial Buildings, Industry, Agriculture, Waste and Wastewater, and Natural and Working Lands. Subsector A more detailed breakdown within a sector (e.g. Diesel Vehicles within Transportation) Year Year of the result. Result Total greenhouse gas emissions for the given sector and year, expressed in million metric tons of carbon dioxide equivalent (MMTCO₂e). For the Natural and Working Lands sector, negative values indicate net carbon sequestration (removals exceed emissions). Unit Unit of the results field. Update Frequency This dataset is updated annually as new EPA SIT, State GHG Inventory, and GHGRP data become available, following EPA's release of revised state-level emissions estimates, which typically lags the most recent inventory year by one to two years. Data Sources and Creation The dataset is compiled by EGLE's Office of Climate and Energy using emissions data downloaded from three EPA sources. For each source, the underlying data and methodology documentation are publicly available. EPA State Inventory Tool (SIT) Data: State Inventory and Projection Tool Methodology: SIT Modules and User Guides (EPA Documentation) EPA State Greenhouse Gas Inventory dataset Data: EPA State GHG Emissions and Removals Data Methodology: Inventory of U.S. GHG Emissions and Sinks by State (Methodology Report) EPA Greenhouse Gas Reporting Program (GHGRP) facility-level data (used for select industrial categories where facility-reported data are more precise than SIT default estimates) Data: Facility Level Information on GreenHouse gases Tool (FLIGHT) Methodology: GHGRP Program Overview and Reporting Methodology Data from each source were downloaded and compiled by economic sector. Non-CO₂ gases were converted to CO₂-equivalent using standard GWP factors (100-year, IPCC AR5). Where a single source did not fully cover a sector, data from a secondary source were substituted or combined to fill coverage gaps. Sector totals were calculated by summing all relevant emissions categories within each sector. The resulting dataset is formatted for use in EGLE reporting products, including the Michigan Statewide Greenhouse Gas Inventory and climate planning materials. Each sector was compiled separately using the data sources best suited to its categories. Emissions data were downloaded from the relevant EPA tool or dataset, converted to CO₂-equivalent (as described in the Overview), and reported in MMTCO₂e for each year from 2005 through 2021. Sector-specific sources and methods are described below. Agriculture: Agriculture emissions data were downloaded from the SIT Agriculture module, which covers enteric fermentation, manure management, agricultural soil management, and liming and urea application. Emissions (CH₄, N₂O, CO₂) were downloaded for each category and compiled into a consistent annual table covering 2005-2021. All agriculture emissions were assigned directly from SIT categories to the Agriculture economic sector; no cross-sector reallocation was required. Subcategory emissions were summed to produce the sector total. Emissions were additionally grouped by animal type (e.g., dairy cattle, poultry) by summing enteric fermentation and manure management figures for each animal category. Electric Power: Electric Power emissions were drawn from three SIT modules: CO2FFC (Electric Utilities) for CO₂ from fuel combustion; Stationary Combustion (Electric Utilities) for CH₄ and N₂O from the same facilities; and Industrial Processes for T&D system losses. Emissions from all three modules were summed to produce the sector total. Only direct emissions from electricity generation and system losses are included. Indirect emissions from electricity consumed by end-use sectors (buildings, transportation, industry) were excluded to prevent double-counting. Industry: Industry sector emissions were compiled from multiple EPA sources. No single dataset covers all industrial emission types at the state level. SIT default modules formed the baseline: CO2FFC (Industrial) for CO₂ from fuel combustion; Stationary Combustion (Industrial) for CH₄ and N₂O; Industrial Processes for manufacturing emissions; and Natural Gas and Oil Systems. Data covering CO₂, CH₄, N₂O, and fluorinated gases were downloaded from each module and compiled by industrial subsector for 2005-2021. Using EPA guidance and crosswalk references, categories were identified where SIT data was unavailable, incomplete, or flagged as low confidence. The EPA State GHG Inventory dataset was substituted for those categories, including iron and steel production, natural gas and oil systems, and select industrial processes. For facility-level categories (cement and lime production), EPA GHGRP/FLIGHT data were used in place of SIT estimates. For cement and lime production, a hybrid time-series approach was applied: EPA State Inventory data were used for years prior to 2010, and GHGRP/FLIGHT facility-reported data were used from 2010 onward, when GHGRP reporting achieved sufficient coverage to be serve as the primary source. Fuel combustion, process emissions, and natural gas and oil system emissions were summed to produce the total Industry sector figure. Residential and Commercial Buildings: Buildings sector emissions were downloaded from four SIT modules: CO2FFC (Residential) and CO2FFC (Commercial) for CO₂ from fuel combustion; Stationary Combustion (Residential) and Stationary Combustion (Commercial) for CH₄ and N₂O. Residential and commercial data were downloaded and compiled separately, then combined into a single sector dataset. Emissions from space heating, water heating, and cooking were summed across both subsectors. Residential and commercial totals were combined into the Residential and Commercial Buildings sector to align with the MHCP sector structure. No cross-sector reallocation was required. Transportation: Transportation emissions were downloaded from three SIT modules: CO2FFC (Transportation) for CO₂ by fuel type; Mobile Combustion (Methane) for CH₄ by vehicle type; and Mobile Combustion (Nitrous Oxide) for N₂O by vehicle type. A hybrid allocation method was applied to produce vehicle-type CO₂ breakdowns. The CO2FFC module provides reliable CO₂ totals by fuel type but does not disaggregate by vehicle type. The Mobile Combustion module provides vehicle-type shares but its absolute CO₂ estimates are less reliable. Vehicle-type percentage shares from the Mobile Combustion module were applied to CO2FFC totals to produce a vehicle-type CO₂ breakdown consistent with the most reliable fuel combustion data. Total Transportation emissions were calculated by summing these allocated CO₂ estimates with CH₄ and N₂O from the Mobile Combustion modules. Natural Working Lands: The Natural and Working Lands sector includes both emissions and carbon removals. Positive values represent emissions; negative values represent carbon sequestration (removals). Data were drawn from the SIT LULUCF (Land Use, Land Use Change, and Forestry) module, covering forest emissions and sequestration, harvested wood products, and agricultural soil carbon. Where SIT coverage was incomplete, the EPA State GHG Inventory dataset was used, specifically for non-CO₂ emissions from forest fires, wetlands, settlements, and flooded lands. Emissions and removals from all land-use categories were summed to calculate a net sector value. Final outputs include annual totals and a subcategory breakdown distinguishing emissions sources from sequestration sinks. Waste and Wastewater: Waste and Wastewater emissions were obtained from the EPA State GHG Inventory dataset; SIT modules were not used for this sector due to incomplete coverage. Emissions (CO₂, CH₄, N₂O) were downloaded and compiled by subsector (landfills, municipal wastewater treatment, industrial wastewater treatment, and minor waste management sources) for 2005-2021. Subsector emissions were summed to produce the sector total. Final outputs for all sectors are structured as annual time series from 2005 to 2021, with subsector breakdowns where applicable, and integrated into the GHG inventory dataset for visualization and reporting.
