Royal Mosa scores 38/100 (Below expectations) on SINK's independent climate assessment — scored from public data only, no company payment can change a number. Last verified July 2026.

That places Royal Mosa joint 397th of 807 companies scored, and 2nd of 3 in Building Materials / Ceramics / Glass / Cement.

Royal Mosa, a mid-sized Dutch ceramic tile manufacturer, has no published company-level GHG data despite energy-intensive operations. Strengths lie in circular product design and third-party certifications; critical weaknesses are absence of emissions targets, no Scope 1/2/3 disclosure, and unverified claims around renewable energy and water management.
