EcoVadis-BCG report warns Scope 3 inaction risks $500 billion in 2030 liabilities

**The EcoVadis-BCG Carbon Action Report 2025 projected over $500 billion in annual global liabilities by 2030 from carbon pricing of Scope 3 supply-chain emissions. Indian companies in global value chains face material financial exposure, as over 90 percent of assessed firms lack verifiable Scope 3 reduction targets. **

EcoVadis and Boston Consulting Group released the Carbon Action Report 2025, warning that transition risk from Scope 3 emissions, specifically potential carbon pricing, could create over $500 billion in annual worldwide liabilities by 2030. Drawing on climate data from more than 83,000 firms, the report found Scope 3 averages 21 times higher than direct emissions, and the projected 2030 liability equals diluting 15 to 20 percent of the S&P 500 cohort's current annual operating profit. Over 90 percent of assessed firms lacked verifiable Scope 3 reduction targets, while one-third of supplier emissions were abatable at low cost.

Global corporates with unmanaged supply chains are affected, facing severe financial threats to long-term enterprise value from carbon pricing exposure exceeding the $76 EU ETS benchmark. Indian suppliers within multinational value chains and Indian corporates with their own complex supply chains face the same Scope 3 blind spot. The report found firms could achieve 3 to 6 times ROI through loss aversion by avoiding future regulatory costs, and that companies actively engaging suppliers were nine times more likely to deliver Scope 3 reduction goals, yet only one in three currently engage external suppliers.

Indian corporates should establish a baseline for supplier emissions and allocate dedicated budgets as immediate priorities to mitigate transition exposure. Companies should adopt the report's five actions, prioritising supplier engagement as the single most impactful, followed by emissions measurement, a climate-aligned management team, a climate transition plan and an emissions reduction budget. Leaders should integrate climate risk into operating models, recognising that early movers build resilience and that engaging suppliers makes firms nine times more likely to meet Scope 3 targets.
