In plain terms
This is a 2002 discussion paper that says it summarises two 1998 discussion papers by an overlapping group of authors, does not point to any later peer-reviewed version of itself, and cites none of the later UK-led work, which it predates, that redid the analysis by a different method, counting other greenhouse gases as well as carbon dioxide, and got a much higher figure.
The claim as recorded
This document is KEO discussion paper G-145 of January 2002, whose title-page footnote states that it summarises its references [20] and [21], two earlier KEO discussion papers dated 1998a and 1998b by an overlapping author group, with a related 1998c article in the Business Journal of PAPAIOS; no later peer-reviewed version of this specific paper is named anywhere in it, and its full 22-item reference list contains no citation of any Strathclyde-authored process-based life-cycle assessment.
Scope and limits
The absence of a Strathclyde-authored citation was checked against this document's own 22-item reference list, title page and abstract only. It CANNOT establish informal awareness, nor whether any later publication by this group engaged with that work, and it is weak evidence of independence in one direction only, since this 2002 document predates the process-based SBSP life-cycle work it is compared with: SRC-212 (2020, PDF p.4) says the 2000 version of this study was the only earlier environmental life-cycle assessment of the technology. Other versions of the study lie outside this document: a 2020 conference paper's reference list gives a 2000 conference paper by the same five authors (13th International Conference on Input-Output Techniques, Macerata) and a 2005 journal paper by an overlapping author group (IEEE Transactions on Systems, Man, and Cybernetics, Part C, 35(3)); neither is held.
What it assumes
No assumptions are recorded against this claim.
Where it comes from
Title-page footnote, printed p.1 (PDF p.4): "This paper summarizes" references [20] and [21]. References, printed p.13 (PDF p.16), read in full: 22 items dated 1970 to 1998. [20] (1998a): "CO2 Emission of Solar Power Satellite" (in Japanese), "KEO DISCUSSION PAPER , No.2". [21] (1998b): a simulations paper, "KEO DISCUSSION PAPER , No.14". [22] (1998c): an article in the "Business Journal of PAPAIOS, Vol.8, No.2". Each of [20] to [22] has four authors, three of whom are on this paper's five-author byline.
