Life cycle inventory databases are called 'libraries' in SimaPro. SimaPro currently includes the following libraries (in the default Professional database):
Agri-footprint (economic allocation)
ecoinvent (allocation, cut-off by classification - included by default if your SimaPro license also includes an ecoinvent license)
EU and Danish Input Output
Industry data 2.0 (includes data from Plastics Europe, ERASM, World Steel, International Molybdenum Association and the Alliance for Beverage Cartons and the Environment)
There are a number of additional databases available (some are free and some are paid) that are not included in SimaPro, but are available for download in SimaPro format:
Agri-footprint (mass and energy allocation)
ecoinvent (APOS and consequential )
ecoinvent (allocation, cut-off, EN15804)
