Castore publishes no emissions figure for its operations or its supply chain, so there is no footprint or trend to report, and the size deduction for an incomplete footprint (0.70x) applies. Its group accounts for the 18 months to 3 August 2025 leave out the statutory energy and carbon disclosure because the directors do not think it practical to obtain, and the accounts to 4 February 2024 say the same. No renewable electricity share, climate target or SBTi commitment was found. It makes garments in 80 factories in seven locations; tier 1 factories are mapped for social compliance, not emissions. No water or waste data was found.
Castore scores 14/100 (Critical concern) 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 November 2026.
