The 5-digit NAICS in the RCRAInfo codes do not count flows present in the 6-digit codes. EIA manufacturing land area is considered part of the urban land total rather than a stand-alone industrial area category. Thus, the flows from the 5-digit sectors must be allocated to the USEEIO sectors. To solve the first problem, BEA-NAICS correspondence for these sectors is approximated after careful inspection and comparison of their definitions in BEA and NAICS systems. Land for national parks is directly assigned to NAICS code 712190, where previously, in both the original USEEIO land satellite table and in Zengs work, national parks were included in the unaccounted land category. The full names of the indicators in the columns are given in Table3. HRSP impacts are driven by particulate emissions, and to a lesser extent in agricultural sectors, ammonia emissions. Fresh vegetables, melons, and potatoes climbed from 10th to 6th position. The Waste management and remediation services industry itself produces most of this commodity (83%). Quantifying scope 3 emissions can be broken into three steps: Step 1: Determine relevant scope 3 categories. 1. The result is available in the National Point Source Releases to Water By Industry 2017 v1.1 dataset34. The v1.2 model data used here for comparison were acquired from the USEEIO-API. 36 are used to create the satellite matrix of environmental flow coefficients, B, in a physical unit per dollar output for a commodity in the model that can be used with the economic data for industries from another year. Both versions of sector attribution modeling use the IWMS statistics on water application rates.

In v2.0, one of the BEA commodities is split into 7 further resolved (more specific) commodities (404+7=411). Capital letters indicate matrices and lower case letters indicate vectors. For v2.0, national totals by sector are modeled by NAICS 6-digit codes. For example, if 562HAZ represents 50% of the total economic value of the disaggregated sectors, then 50% each flow is allocated to 562HAZ. It is further assumed that the Hazardous waste collection, treatment, and disposal sector (562HAZ) collects all hazardous waste using specialized equipment. The intent of this detailed analysis is to provide information and recommendations on available opportunities to work with County vendors to improve environmental performance and advance the health and wellbeing of the residents of Alameda County and beyond., US Department of Energy Depending on the source, scope 3 emissions can be quantified using either primary data specific to the activity within a company's value chain or secondary data such as industry averages, proxy data, or other generic data. Heijungs, R. & Suh, S. The Computational Structure of Life Cycle Assessment. Water withdrawal impact intensity differences are attributed to allocation methodology changes for the irrigation, mining, and industrial USGS water use categories. Sci. EF Hub. The sets of commodities in the top 20 from v2.0 and v1.2 in the production and consumption-based rankings are nearly identical, with some notable substitutions and some exchanging of places. This can be performed by subtracting the import matrix, Um from the Use matrix to estimate a domestic Use table, Ud, as in Eq. Emission factors should at a minimum include emissions from fuel combustion, and should, where possible, include cradle-to-gate emissions of the fuel (i.e., from extraction, processing, and transportation to the point of use). Model coefficient matrices can be converted to reflect different currency years. For v2.0, value added direct and indirect impact coefficients from N are ~1 for all sectors. BLM/OC/ST-13/002+1165 https://www.blm.gov/sites/blm.gov/files/pls2012-web.pdf (U.S. Bureau of Land Management, 2013). This bundle contains all of the available Global Emission Factors including: Global Electricity Factors, Global Homeworker Factors and Global Hotel Factors at a 10% discount. 2010 Manufacturing Energy Consumption Survey. The data for water withdrawals, criteria and hazardous air emissions, point source industrial releases to ground, point source releases to water, greenhouse gases, land use, employment, and value added have been updated in v2.0 and incorporate methodological improvements. Sarah Cashman, Bill Michaud and Ally Brown assisted with project management. RCRAInfo data are available by 5- and 6-digit NAICS codes, which map to the disaggregated sectors as shown in Table6. Conserv. National biennial hazardous waste report 2017. https://www.epa.gov/hwgenerators/biennial-hazardous-waste-report (U.S. Environmental Protection Agency, 2018). Global warming potential (GWP) is a factor describing the radiative forcing impact (degree of harm to the atmosphere) of one unit of a given GHG, relative to one unit of CO 2 over a 100-year time horizon. Model coefficient matrices may be obtained in purchasers price through adjustment of values from producers price. USEEIO models are under continuous revision with intermittent releases. Producer price is the price of a commodity reflecting an industrys cost to produce it including commodity taxes11. The model will support BETOs mission to develop technologies for producing cost-competitive advanced biofuels from non-food biomass resources, including cellulosic biomass, algae, and wet waste (e.g., biosolids).. 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. A symbol represents the transposed (rows and columns switched) form of a matrix or vector. US Department of Defense Birney, C., Conner, M., Specht, J. Google Scholar. L is in commodity x commodity form and represents the total inputs of commodities (rows) used to make a commodity (columns).

Darker shade indicates a relatively higher score. In v2.0, these land use categories are allocated to sectors using BLS employment data43. Five categories are reported in year one and 12 in year five. All these data products were uploaded to the EPA Data Commons64 and are retrieved by useeior during model building as specified in the model configuration file. https://www.eia.gov/consumption/manufacturing/data/2010/ (U.S. Energy Information Administration, 2013).
