This report describes the preparation of those factors with a background on the modeling associated with this preparation, and presents extensive analysis of the factors, including supporting equations and results in two appendices. In v1, the Scrap commodity was removed from the model following a methodology presented by BEA for deriving a total requirements matrix11. Scope 3 emissions are the result of activities from assets not owned or controlled by the reporting organization, but that the organization indirectly affects in its value chain.

The national release estimates for pesticides were not updated in v2.0, where data on application for these chemicals to vegetables was from 2010. Figure 2. National totals of flows (physical movements of specific resources, emissions or employment) by industries are used as the sources of environmental and employment data. Publishers note Springer Nature remains neutral with regard to jurisdictional claims in published maps and institutional affiliations. The resulting coefficients from these calculations can be interpreted as a measure of the environmental intensity of a sector in the year the environmental data are reported, but given in terms of the IO year dollar value. US Environmentally-Extended Input-Output (USEEIO) is a family of models designed to bridge the gap between traditional economic calculations, sustainability, and environmental decision-making. Top 20 commodities by composite impact score for models v2.0 and v1.2 calculated using (a) the total US production demand vector and the direct perspective and (b) using the total US consumption demand vector and the final perspective. Improvements in modeling national totals of industry and environmental flows are described. For these datasets, the national totals by sector were extracted directly from the published datasets5,7. Publications Office of the European Union 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. Birney, C., Conner, M., Specht, J. Discharge Monitoring Report (DMR) Pollutant Loading Tool. This decrease is likely a result of fuel source changes in the electricity production over this period69. Ingwersen, W. & Yang, Y. USEEIO v1.1 - Matrices. BLM/OC/ST-08/001+1165 https://www.blm.gov/sites/blm.gov/files/pls07.pdf (U.S. Bureau of Land Management, 2008). Therefore, selecting the correct project type is pivotal. 32 are the same as the Value Added row values in the model N matrix. In the case of the new waste commodity and industry totals, they summed to within 1% of the Waste and Remediation commodity and industry totals in the 2012 BEA Detail Make and Use tables. J. Supply Chain Greenhouse Gas Emission Factors for US Industries and Commodities (No. EPA researchers worked with partners at US Department of Defenses (DOD) environmental research programs (the Strategic Environmental Research and Development Program and the Environmental Security Technology Certification Program) to use USEEIO as the basis for re-creating an input-output model tailored to the specific needs of the DOD, such as life-cycle analysis formilitary equipment. 7. Sector correspondence between the BEA and NAICS codes, or the Sector Crosswalk, is created to connect the two classification systems and enable mapping from one system to the other. For v2.0, value added direct and indirect impact coefficients from N are ~1 for all sectors. M.L. Emission Factor Database European Environment Agency The major challenge with this section is establishing accurate IO transactions between the disaggregated sectors by using both monetary and material flow data. Break-out sessions by USEEIO format.
