You may enter the LCI database on the LCA Commons homepage, select the unit processes you wish to download, select the "Downloads" button, and then proceed to the download page. On the download page you may select the format in which you wish to download data. You will then receive an e-mail in which you can access your query and download the data.
Your download will be a zipped file that includes the XML, JASON-LD, or excel formatted processes which you have requested. These files can be easily imported into openLCA software (not the excel format) or imported into other commercial tools with some level of effort.
