The tables report results for liquefied natural gas (LNG) and carbon capture and storage (CCS) systems, estimate-level harmonization results for each step, and greenhouse gas (GHG) emissions disaggregated by life cycle stage. Figures display results of cumulative harmonization, LNG and CCS box and whisker plots alongside the results for (regular) natural gas systems, and box and whisker plot of estimates of methane leakage.
