Wahaca has built a credible mid-scale sustainability programme with certified carbon neutrality since 2016, menu-wide carbon labelling, and strong waste diversion (86% recycling). But operational and supply chain emissions lack public quantification, net zero targets conflict, and there's no standalone impact report or board governance disclosure.
