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. Scores are free. Nobody can pay to change a score, speed it up or hide it. Last verified October 2026.

What evidence is Douze Paris's score based on?
10 sources used in this assessment. All publicly available. Each row shows which of the ten questions it informed.
30% of them were published by Douze Paris itself; the rest come from independent sources.
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.
