Zen Educate's UK footprint was 508 tCO2e in 2024, down from 760 t in 2022 mainly through changes in how it counts supply-chain emissions, while its own operations' emissions rose sixfold. Its accounts and its carbon plan disagree on its direct emissions, and its figures leave out educators' travel to schools. It aims to halve emissions by 2030 and reach net zero by 2050, with no SBTi target, and it publishes no water or waste data.
Zen Educate scores 52/100 (Making progress) 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.
