The Carbon Action Report 2025 – a collaboration between EcoVadis and BCG – reveals both the ROI of bold Scope 3 efforts and the high cost of inaction.
Built on data from 133,000 EcoVadis carbon scorecards across 83,000 companies, it delivers the clearest picture yet of the business case for supply chain decarbonization. It reveals the financial, strategic and reputational risks of delaying action – and the five key Scope 3 steps driving measurable results for companies today.
Key findings include:
Scope 3 remains a blind spot: Supply chain emissions are on average 21 times higher than direct emissions, yet more than 90% of companies lack upstream reduction targets.
The cost of inaction is steep: By 2030, unmanaged Scope 3 emissions could translate into more than $500B in annual liabilities, equal to 15 to 20% of EBIT for S&P 500 firms.
The upside is tangible: Up to 50% of supplier emissions can be cut cost-neutrally, delivering a 3–6x return on investment. One third of these emissions can be cut for less than $12/tCO₂e.
Supplier engagement is critical: Companies that actively engage their suppliers are 9 times more likely to achieve their Scope 3 targets, yet only one in three do so today.
