CDP is a questionnaire, not a standard
This distinction matters more in practice than it sounds.
A **standard** sets how to calculate. A **questionnaire** sets what has to be answered. And a box left unanswered shows up in the score.
## The problem CDP stated itself
CDP published a technical note mapping which Scope 3 categories are relevant by sector. Its introduction is honest about why the map is needed.
The criteria GHG Protocol offers for judging Scope 3 relevance are qualitative, so interpretations diverge. The result is written like this:
> companies may end up measuring and reporting on **categories that are easy to calculate (e.g. business travel)** rather than the categories where most of their emissions occur but that are harder to calculate.
## How easy is what is being measured
The same document puts a number on it. Category 6, "business travel", and category 7, "employee commuting", are described as negligible across all high-impact sectors, at **an average of 0.10% and 0.20%** of total Scope 3 emissions respectively.
If business travel emissions are being compiled with care, that care is going into 0.1% of the total.
Where the rest of it is, is in the next article.
