Douze Paris scores 23/100 (Significant gaps) on SINK's independent climate assessment — scored from public data only, no company payment can change a number. Last verified October 2026.
That places Douze Paris joint 733rd of 806 companies scored, and 4th of 4 in Jewellery & Watches.
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.

10 sources used in this assessment. All publicly available. Each row shows which rubric questions it informed.
Provisional evidence. Published with 2 independent parties, below our full-confidence threshold of 3. Every source shown below passed the same quality checks as any other score: all live, none from data aggregators. There is simply less of it.
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.
