Further information about openLCA can be found on the openLCA website and within the WARM Version 15 user guide. OpenLCA is a free, open-source software for life cycle assessment developed by GreenDelta. Version 15 is also available in a tool based on a database developed in openLCA software. These updates resulted in changes to most emission factors in WARM. Department of Energy (DOE) Energy Information Administration's (EIA's) 2017 Monthly Energy Review while state electricity grid emission factors were updated based on the 2018 update to the eGRID database. average electricity mix were updated based on the U.S. The non-biogenic carbon content of mixed municipal solid waste (MSW) was updated using annual waste disposal data from EPA's Advancing Sustainable Materials Management: Facts and Figures Fact Sheet. Greenhouse Gas (GHG) Emissions and Sinks: 1990-2016. The latest 2016 statistics on the carbon content of fuels, landfill methane generation distribution (by type of landfill), and landfill gas recovery and flaring rates have been incorporated from EPA's Inventory of U.S. In addition, EPA reorganized the order of materials in WARM and made regular updates to various factors in the model using current data sources. They also include indirect impacts, including the collection, sorting and transportation of a material. The economic impacts include the direct impacts associated with the actual transformation of recyclable materials into marketable products. The update to WARM Version 15 includes economic impacts from employment (labor hours), wages and taxes. Prior to the release of WARM Version 15, WARM did not include potential economic benefits from waste reduction or alternative waste management practices. Desktop Central Processing Units (CPUs),.In addition, users are now easily able to see the production and end-of-life greenhouse gas (GHG) and energy impacts along with other results.ĮPA replaced personal computers with the following electronic materials categories: The main changes to WARM Version 15 include replacing personal computers with more specific electronics categories, incorporating economic impacts into the model, and updating the various factors in the model using current data sources. Users are still able to access the Excel-Based Tool (xls)
