In Fig. Once all the requirements are installed, the generation of v2.0 takes place in a single buildModel function to load the various data components and build the model. Carbon intensity of electricity production (CO2 or CO2e per unit electricity). The relationship table presents a hierarchy of the BEA codes at three levels of detail: sector (21 sector groups), summary (71 sector groups), and detail (405 sector groups), as well as how each level relates to the NAICS code structure. How to Use the EPA USEEIO Model - A Workshop & Birney, C. useeior. Although QCEW employment data is one of the main sources in the creation of the National Employment Matrix, the National Employment Matrix also incorporates data from the Occupational Employment Statistics program (OES), the Current Employment Statistics program (CES), and the Current Population Survey (CPS)60. Since SIMAP does not have an emissions category for other GHG, these emissions were added to the CO2 emissions factors as CO2-equivalents. The Economic Census data provides monetary receipt values by detailed NAICS codes and customer class. Report No. Emissions of pesticides from agricultural activities are excluded from this dataset as they are captured in the pesticides table. A., Los, B., Stehrer, R. & Vries, G. Jde Slicing up global value chains. 58% of the value of the original waste sector is allocated to the intersection of Hazardous waste treatment and disposal with itself, while the Hazardous waste treatment and disposal column contains 89% of the total value of the intersection disaggregation. flowsa performs extraction, transforming and loading (ETL) processes for bring in original data sources, as well as the modeling steps to create a standard flow-by-sector output, which can be retrieved using the getFlowBySector function and passing the name of the flow-by-sector of interest. In v2.0, withdrawals are calculated for 64 crops identified in the 2017 USDA CoA. Young, B., Birney, C. & Ingwersen, W. National point source releases to ground by industry 2017 v1.1. The v1.2 model data used here for comparison were acquired from the USEEIO-API. Sci. An analogous series of direct impact coefficient (D matrix) comparison charts are also provided for interpretation68, but are not analyzed in depth here. Birney, C., Li, M. & Ingwersen, W. National employment totals by industry 2017 v1.1. zenodo https://doi.org/10.5281/zenodo.6370101 (2021). The v2 industry output and commodity output totals for each commodity and industry in the model were both found to be within 1% of the original totals. The Sector Crosswalk can be used to identify a NAICS code associated with a USEEIO code, and tools like the Census NAICS code search75 can be used to identify NAICS codes associated with the purchase. In flowsa, source classification codes are used to allocation emissions to one or more NAICS through activity-to-sector mapping files. Supply Chain Greenhouse Gas Emission Factors for US Industries and The commands for building v2.0 with useeior v1.0.0 along with the results of the validation procedure are shown in a model building and validation document65. In other words, the monetary and physical flows occur in the same direction: makers of the waste treatment commodity receive both the physical waste to be disposed and the money for the disposal service. How to use EEIO model within Sustainability Manager: The quantity equals the cost, and the company spend code is used as reference data. Multiplying emissions of a given GHG by its GWP gives us the CO 2 equivalent emissions. These include all the types of resource use and environmental releases/losses from v1.15 plus the three additional waste generation datasets created for v1.27,8. Data are assigned to sectors based on facility-reported NAICS. & Birney, C. USEEIO v2.0.1-411 Build and Validation Script. The equivalent value is 1.44E-5in v1.2 (sheet B, cell D681 of)71. Correspondence to 18. Services to buildings and dwellings (561700): the entirety of the 562000 commodity produced by this sector is assigned to the Remediation services sector (562910), as it is assumed that the services provided by this sector deal with site-specific remediation. Following this mapping, each satellite table is assessed to ensure that no environmental flows were lost during the transformation. Report No. Article In the production vector, the direct imports both used by final consumers and industries are removed. Table5 provides a list of all final demand columns included in the BEA Detail Use table and their respective association with the final demand variable. The GHG Protocol defines 15 categories of scope 3 emissions, though not every category will be relevant to all organizations (see Figure 1). Ei, a national total of flow by industry per year consisting of the concatenation of all the satellite tables described above, is available in varying years. Tobacco, cotton, sugarcane, peanuts, sugar beets, herbs and spices, and other crops fell 14 places, apparently to decreased water consumption. The emission factor rating takes into account the test rating, the number of sources tested, and whether the sources are selected at random, represent the industry population, and are sufficiently specific (e.g., to fuel type, design, etc.) FLOWSA v1.0.1. Overview of GHG Protocol scopes and emissions across the value chain. Timberland estimates are based on MLUs ungrazed forest land rather than total timberland, which reduces land use attributed to forest. The change in crop categorization coupled with differences in survey responses resulted in changes in industry impact intensity. In Water_national_2015_m1, employment data are used to allocate water withdrawals to relevant sectors identified by USGS.
