Limited evidence. Published with 2 independent parties, below our full-confidence threshold of 3. Every source cited on this page passed the same quality checks as any other score: all live, none from data aggregators. There is simply less of it.
Douze Paris publishes no emissions, energy or water data and has no measurable climate targets, and no SBTi entry. The micro-enterprise (6–9 staff) states that it uses recycled gold from RJC-labelled suppliers and favours short supply chains, but these claims are founder-led and not independently verified.
Douze Paris scores 23/100 (Significant gaps) on SINK's independent climate assessment, scored from public data only. Fees pay for the review, never the result. Last verified October 2026.

Same ten questions for every company. No private weighting.
SINK = (0.3 × Base + 0.7 × Performance) × Scale10 sources used in this assessment. All publicly available. Each row shows which of the ten questions it informed.
This score is published on ten verified sources, but only two independent sources describe the company itself; the others are register and database checks showing what is absent. A third independent source that writes about Douze Paris's environmental practices would move this to full confidence. The score itself is unaffected by the count.
