It remains in the responsibility of the LCA practitioner 8 LCA4CCU to be aware of such differences and to consider them adequately in the interpretation of the results. [...] Further issues which fall out of the scope of LCA for CCU specifically, but are important, are the issues highlighted in terms of the inconsistencies over the method used for climate change impacts, both the version issue (TAR, AR4, or AR5) and also the application of these methods. [...] The benefits in terms of GHG emissions will, however, depend on the carbon footprint of the energy used for the CCU process, the carbon emitted in the upstream and downstream processes and the lifetime of the product it replaces. [...] According to EN ISO 14040:2006 (chapter 5.2.1.1), “the scope of the LCA study should be sufficiently well defined to ensure that the breadth, depth and detail of the study are compatible and sufficient to address the stated goal.” Due to the iterative nature of LCA, the scope may have to be revised due to unforeseen limitations, constraints or as a result of additional information. [...] The duration / lifetime of the product: “how long” The functional unit shall be consistent with the goal and scope of the study.
