Dentsu operates as a Big Six advertising holding company with documented fossil-fuel client work—18 contracts in 2024–2025—undercutting its otherwise-ambitious net-zero science-based targets. Operationally, emissions rebound post-2022 despite SBTi validation. The firm excludes advertised emissions (32× its footprint) from climate goals, a structural blind spot.
