MSQ's footprint was 5,007 tCO2e in its year to February 2025, flat against its 2020 baseline: its own operations' emissions are down 68%, but its supply-chain emissions rose. It has SBTi-approved near-term targets, though its supply-chain target is per employee, and it says both that it stopped offsetting in 2023 and that it buys carbon credits. Its agencies have worked for Shell, BP and British Gas, and Clean Creatives named MSQ in its 2023 list of agencies working for fossil-fuel companies.
