Unmanaged Scope 3 Emissions Could Expose Companies to $500 Billion in Liabilities

Research cited by EcoVadis Climate Ambassador Dexter Galvin shows that companies ignoring supply-chain emissions could face more than $500 billion in annual liabilities by 2030, yet fewer than one in ten has set formal Scope 3 reduction targets. The analysis was released ahead of COP30 in Belém, where credibility of corporate climate commitments came under heightened scrutiny.

On average, Scope 3 emissions are 21 times larger than a company's direct operational and energy-use emissions combined, yet only 24% of companies currently report on them and just 8% have set formal reduction targets. New regulations including the EU's Corporate Sustainability Reporting Directive (CSRD) and Carbon Border Adjustment Mechanism (CBAM) are redefining mandatory corporate transparency, while carbon pricing expansion means that companies without clear supply-chain emissions visibility face higher operating costs, constrained financing and exposure to regulatory shocks. By contrast, organisations that engage suppliers early are estimated to capture three to six times the return on their decarbonisation investments.

The scale of the Scope 3 challenge has direct implications for Indian companies embedded in global supply chains, particularly those supplying European and US multinationals subject to CSRD and CBAM. Indian exporters in sectors such as steel, textiles, chemicals and automotive components increasingly face demands from buyers to submit GHG data as part of supplier assessments. Companies that lack standardised reporting infrastructure risk being deprioritised or excluded from supply contracts as due diligence requirements tighten. Advances in digital reporting tools and shared data platforms are beginning to lower the cost of supplier engagement at scale.

Five practical levers identified in the analysis include treating suppliers as partners rather than compliance obligations, building structured GHG inventories, embedding executive accountability for emissions performance, developing company-wide transition plans, and allocating dedicated budgets for supplier engagement and data systems. Companies that act on these levers before regulatory pressure intensifies stand to protect profitability, strengthen operational resilience and contribute to the adaptation and resilience objectives that COP30 sought to operationalise. The window to build these capabilities at lower cost is narrowing as mandatory disclosure regimes take effect across major markets.
