A carbon figure is only as good as the sentence under it.
Residention records emissions with the factor used, the source of that factor, the basis of the activity data and the share of the portfolio it was read from — so a number can be defended rather than merely presented.
Carbon reporting collapses when three different kinds of figure are added together: something measured from a meter, something declared by a supplier, and something estimated from a benchmark. The sum looks like one fact and is actually three claims of very different strength.
The platform keeps them apart at the record level, not in a footnote. Every total states its basis and its coverage, and a portfolio with gaps reports gaps.
