CMC Markets reports Scope 1, 2 and 3 emissions, including purchased goods, but its total market-based emissions rose from 11,536.4 to 18,897.1 tCO2e in FY2026, which it puts partly down to better data and partly to higher spend and travel. Its 2050 net-zero target is self-set, it has no formal transition plan, and its own report says climate governance lost focus during the year and climate metrics are not linked to pay.
