Scope and limits

These are 2014 medians and the underlying literature is older still, so they are NOT current figures for technologies whose emissions intensity has fallen since, particularly photovoltaics. The column explicitly includes infrastructure, supply-chain emissions and the albedo effect, which is a wider boundary than some other compilations use, so it is not automatically like for like with any other comparator set. The full literature basis sits in AR5 Annex II section A.II.9.3, which was not retrieved. AR6 Working Group III does NOT restate this table: its own Annex III is "Scenarios and Modelling Methods", a different document, and its Chapter 6 discusses lifecycle emissions per technology in prose citing different studies rather than in a consolidated table; that was checked directly against Chapter 6's contents and its solar subsection at pp.630-633, though not every technology subsection was checked exhaustively.
