2.1 Literature selection
-
Studies that did not perform LCA
-
Review papers
-
LCA studies that developed scenarios for future development of an existing technology but did not upscale a technology
-
Studies that performed laboratory LCA but did not perform upscaling
-
LCA studies that upscaled LCIA (life cycle impact assessment) results only without explicit upscaling of inventory processes and process data
-
Ex ante LCA studies that did not clearly describe the upscaling procedure applied in a case study or did not describe such a procedure at all.
