Inaction on Scope 3 emissions could cost corporates up to 20% of Annual EBIT. ESG Broadcast Shares key takeaways.
The EcoVadis and Boston Consulting Group (BCG) jointly released their Carbon Action Report 2025, which warned global corporates about massive impending financial liabilities. The transition risk associated with Scope 3 emissions—specifically the potential for carbon pricing—is projected to create over half a trillion dollars ($500 billion+) in annual worldwide liabilities by 2030, based on a review of companies disclosing their emissions to EcoVadis. Unmanaged supply chains pose severe financial threats to long-term enterprise value.
Supply chain emissions are a critical financial blind spot for many global businesses, despite the escalating pressures of climate change. Scope 3 averages 21 times higher than direct emissions. The anticipated 2030 liability was equivalent to diluting 15 to 20 percent of the S&P 500 cohort’s current annual operating profit. Over 90 percent of firms assessed lacked verifiable Scope 3 reduction targets.
Investing in climate action for the supply chain today presented corporates with a powerful opportunity for strong, quantified financial returns. Firms could achieve up to a 3-6x ROI through loss aversion. This return was realized primarily by avoiding future regulatory costs that were projected to exceed abatement expenses significantly, exceeding the $76 EU ETS benchmark. One-third of supplier emissions were found to be abatable at low cost.
“Climate change has become a financial and strategic reality for business leaders as physical and transition risks are already shaping outcomes for corporates, investors and society. By 2030, corporates could face over $500 billion in global liabilities from potential carbon pricing of Scope 3 supply chain emissions. However, targeted actions to reduce supplier emissions can help to mitigate this risk and deliver real value. This report, developed with EcoVadis, leverages climate data from more than 83,000 firms to lay out the business case for Scope 3 emissions reduction and identify five practical actions that enable corporates to manage their exposure and build resilience. Climate risk in supply chains is a business risk for corporates. Leaders must act now to safeguard value and secure a long-term advantage”, said Diana Dimitrova Managing Director and Partner, BCG
The report identified five impactful actions necessary for transitioning ambition into verifiable delivery on essential Scope 3 targets.Engagement with suppliers was noted as the single most impactful action followed by measurement of emissions, Climate aligned management team, Climate transition plan and emissions reduction budget. Corporates actively engaging suppliers were found to be nine times more likely to successfully deliver established Scope 3 reduction goals. However, only one in three currently engaged their external suppliers.
Strategic significance lies in viewing Scope 3 action not as a sustainability objective, but as a critical driver of immediate and material financial performance. Leaders had to integrate climate risk into their operating models. Establishing a baseline for supplier emissions and allocating dedicated budgets were immediate priorities for mitigating urgent transition exposure. Early movers would build resilience and secure a critical long-term competitive value.
