How Dow Used the Carbon Footprint Ledger to Unlock a New Revenue Stream

The Obstacle

The chemical industry sits at the intersection of nearly every major value chain in the world. When Dow decided to make lower-carbon products commercially available at scale, the implications reached far beyond its own operations.

Lower-carbon chemicals, produced across Dow’s global portfolio, give customers a credible, high-integrity path to reducing the emissions embedded in what they buy. For Dow, that translated directly into new segments, a differentiated offer in an increasingly competitive landscape, and a durable competitive advantage. The multibillion-dollar Fort Saskatchewan, Alberta, expansion project, once constructed, is designed to operate as an integrated ethylene cracker and derivatives facility with net-zero Scope 1 and Scope 2 carbon dioxide equivalent emissions. This project represents the next frontier of that ambition: a demonstration that lower-carbon products at industrial scale can be technologically viable, financially attractive, and commercially compelling.

Scaling lower-carbon products at that level of capital investment requires more than technological conviction. It requires a commercial model that can generate returns sufficient to sustain and grow the ‘Path 2 Zero’ decarbonization program. Monetizing lower-carbon attributes, at scale and with credibility and integrity, was the critical missing piece.

Two structural problems stood in the way.

The first was geographic mismatch. Lower-carbon assets are built only where the feedstock, technology, and economics make sense. But customers seeking lower-carbon materials are rarely in the same place, and physical supply chains cannot simply be redrawn to match.

The second was attribution. In a production network of Dow’s complexity, emissions benefits spread across thousands of products and dozens of sites. Allocating those benefits to a specific customer purchase, with the mathematical precision and full auditability that customers require, had never been done at this scale.

The Approach

A structured market analysis confirmed that the opportunity was real. Customers across global value chains were actively publishing emissions reduction commitments and looking for credible solutions from their suppliers to meet them. The missing piece was a shared, scalable mechanism to connect that demand to verified supply.

BCG brought the technical depth, commercial rigor, and ‘digital build’ capability to develop the solution. Nearly 40 experts from BCG and BCG X worked with Dow over three years to deliver three complementary, integrated components: a rigorous carbon accounting methodology, an industrial-scale digital platform, and an intuitive user experience designed to make the system commercially actionable from day one.

The Carbon Accounting Methodology

The foundation of the Carbon Footprint Ledger (CFL) is a methodology grounded in chain-of-custody principles and group-level mass balance logic. Rather than developing a proprietary framework, the team deliberately anchored the approach in ISO 14067, the leading international standard for product carbon footprint development, and the Greenhouse Gas Protocol Product Life Cycle Accounting and Reporting Standard. Grounding the methodology in globally recognized standards ensured transparency and gave commercial counterparties an immediately recognizable basis for trust.

The methodology defines precisely how lower-carbon attributes are allocated across products in a way that is mathematically rigorous, aligned with the realities of complex production networks, and fully defensible in a commercial negotiation or audit. Environmental guardrails are built in, preventing ‘double counting’ and ensuring that customers not purchasing lower-carbon products are not inadvertently assigned those benefits.

The Digital Platform

In parallel, BCG and Dow designed and built the CFL digital platform—a first-of-its-kind software solution embedded directly within Dow’s existing IT and data infrastructure. Architected from the ground up to integrate with Dow’s Enterprise Resource Planning (ERP) systems, it draws on standard production data to calculate product-level carbon footprints (cradle-to-gate) across thousands of products and multiple sites in near real time. Low-carbon attributes move through Dow’s production networks with the same discipline as physical materials, making the entire process auditable end to end.

The User Experience

The third component proved as commercially significant as the first two. The CFL was designed so that sales teams and customers could see exactly how a product carbon footprint was derived, attribute by attribute, from raw material to finished product. Rather than asking customers to trust a number, the platform makes the entire calculation visible and navigable.

That shift from assertion to demonstration transformed the commercial conversation. Customers could interrogate the logic, satisfy their own audit requirements, and incorporate Dow’s lower-carbon products into their own greenhouse gas (GHG) emissions reporting with full confidence.

Both the methodology and the platform were independently audited and certified by ERM-CVS as consistent with ISO 14067 (2018) and with Greenhouse Gas Protocol Product Life Cycle Accounting and Reporting Standard (2011). BCG also supported Dow in bringing the CFL into live commercial agreements and joined Dow at the New York Climate Week in 2024 and 2025 to present the approach to customers, standard setters, and regulators, helping shape the broader commercial and policy landscape around industrial carbon accounting.

The Result

The Carbon Footprint Ledger has delivered measurable value creation across three dimensions: a new commercial reality for Dow, a credible solution for its customers, and a replicable model for the broader industry.

For Dow, this means a scalable new revenue stream, built on the ability to package and sell verified lower-carbon attributes across geographies, independent of where lower-emission assets are located:

• Contracts are signed, further agreements are in negotiation, and a strong pipeline of early-stage conversations is developing.
• A landmark commercial deal has demonstrated the model’s viability in live market conditions.
• The commercial model has created lasting value—a self-sustaining business case for lower-emission investment that grows stronger with every contract signed.

For Dow’s customers, it means high-integrity product carbon footprint certificates that translate environmental attributes into tangible business value:

• Certificates are backed by independent assurance and strict guardrails against double counting.
• Reductions are real, traceable, and fully auditable.
• Current contracts on the platform represent several million metric tons of GHG emission reductions over the next decade.

For the broader industry, it provides a replicable blueprint for long-term value creation, available to any organization in a hard-to-abate sector:

• Customer case studies, available at dow.com, demonstrate the model’s applicability beyond Dow.
• The methodology is designed to be adopted across value chains and sectors.
• Dow has shown that there is no tradeoff between profitable growth and sustainability—in fact, they reinforce one another.
