Context
3 contextsThe same product, read against different projects. A material is never sustainable on its own — only relative to a target, a use, and a place.
A floor isn’t low-emitting. It’s low-emitting for a California school.
Pick a rating target, a use, and a region, and the same evidence changes meaning. An emissions test that’s required by law in one project doesn’t even apply in another. Litmus reads the product against the context — it never rates the product alone.
The same evidence, judged differently
3 of 4 shared rows change meaningEach row is one piece of evidence a product might carry. Each column is a project. Where a row changes color across the columns, the product’s sustainability story changed — without the product changing at all.

Healthcare · California
LEED
A LEED v4.1 healthcare interior in California. Indoor-air evidence carries the most weight, and California's own emissions method sits underneath the LEED credit.

Workplace · United Kingdom
BREEAM
A BREEAM-assessed office fit-out in the UK. The questions rhyme with LEED, but the valid evidence is European — EN test methods, CE marking, and recognized responsible-sourcing schemes.

Education · California
No rating target
A California K–12 school with no green-building certification in play. Even with no program to chase, state expectations for low-emitting materials still set the bar.
