The libraries

Every public library, read into one database

Each publisher describes the world its own way: its own categories, its own boundaries, its own warming basis. We read every library at the source, keep the publisher's own row beside ours, and file all of it in one model, so two factors from two countries can be compared, and cited.

What the publisher wrote

Road dieselADEME, FR
one categoryFuels › Liquid fossil fuels

Four publishers, four labels, one thing being measured. Every value is filed under one shared category, and the publisher's own label is kept beside it.

Three examples, each drawn from the catalogue as it stands today.

One boundary vocabulary

The stages are named the same way everywhere, so a total is comparable and its parts still add up.

One warming basis

GWP100, from IPCC AR5 to AR6, applied to the gases rather than left as a footnote.
