In plain terms

The authors say an environmental claim about a space technology counts for nothing unless a proper standardised life-cycle study backs it, and that whoever makes the claim should be able to hand the evidence to anyone who asks without making it hard to get.

The claim as recorded

The authors state that "unless a claim can be scientifically quantified by results from an assessment which follows a standardised methodology, it means nothing", and set out an eight-point reporting framework requiring that "all environmental sustainability claims must be substantiated by evidence (i.e. a space LCA study), avoiding generic buzz words unless quantifiable", with documentary evidence "available to any third-party to whom communication is made or intended, with no unreasonable effort associated with obtaining a copy".

Scope and limits

The paper gives no single definition of greenwash; it defines it operationally through a table of cautioned terms and through the eight-point framework. This is a claim about publication standards, not about SBSP's environmental performance, and may not be cited as evidence either way on the carbon question. The framework's "must" is the authors' own prescription and binds nobody.

What it assumes

No assumptions are recorded against this claim.

Printed p.3: "unless a claim can be scientifically quantified by results from an assessment which follows a standardised methodology, it means nothing. Without this, unlocking the substantial funding required to make SBSP a reality becomes unlikely, but the risk of greenwashing is high." Printed p.10, framework point 2: "All environmental sustainability claims must be substantiated by evidence (i.e. a space LCA study), avoiding generic buzz words unless quantifiable." Point 7: "When making an environmental sustainability claim, documentary evidence must be available to any third-party to whom communication is made or intended, with no unreasonable effort associated with obtaining a copy."
