Value chain · CLM-0845
In plain terms
NASA states in its own report that its carbon figures come from a method that converts money spent, by industry sector, into emissions, combined with terms based on mass and area.
The claim as recorded
NASA describes its own greenhouse gas method as a "Hybrid mass and spend-based Economic Input Output - Life Cycle Analysis (EIOLCA)" and states that "This method is based on aggregate sector-level economic data, such as the North American Industry Classification System (NAICS)", with the report's own formula summing a total-dollars-times-gCO2eq-per-dollar term alongside mass and area terms.
Scope and limits
This records what NASA states about its own method, which is the fact needed to adjudicate the dispute at CLM-0826 and CLM-0827 on primary text rather than on a critic's characterisation. It does NOT by itself establish that the method is inappropriate; that is a contested judgement held separately at CLM-0825. The word "Hybrid" is part of the fact: NASA does not describe the method as purely spend-based, and any claim that it is purely spend-based would misstate the source.
What it assumes
No assumptions are recorded against this claim.
Where it comes from
p.62 (PDF p.79): "This method is based on aggregate sector-level economic data, such as the North American Industry Classification System (NAICS)". Method named in Figure 8 and Figure 17 as "Hybrid mass and spend-based Economic Input Output - Life Cycle Analysis (EIOLCA)".
