Omnicom has SBTi-validated near-term emissions targets and publishes Scope 1, 2, and 3 data, but emissions rose in 2024 after initial 2019–2023 decline. The core weakness: systemic reliance on fossil fuel clients (ExxonMobil, Shell, Chevron, TotalEnergies) and board ties to high-emissions industries undermine credibility of climate commitments.
