Product carbon footprint: CO₂ as a strategic cost driver

By Christian Böhler and Andrea Hagenmeyer

CO₂ is no longer just an environmental metric – it is becoming a direct cost driver for industrial companies. As the EU phases out free emission allowances from 2026 and the Carbon Border Adjustment Mechanism takes effect, Scope 3 supply chain emissions will dominate carbon cost exposure. Companies that proactively integrate product carbon footprint management into strategy, product design, and supply chain decisions will be better positioned to protect margins and gain a competitive advantage in a carbon-constrained market.

Carbon dioxide emissions are becoming a core cost variable for industrial companies. Evolving regulatory frameworks – led by the European Union's Fit for 55 package, the EU Emissions Trading System (EU ETS), and the Carbon Border Adjustment Mechanism (CBAM) – are fundamentally changing how manufacturers account for carbon costs. As free emission allowances are phased out from 2026, the financial implications of carbon management are no longer theoretical. For senior decision-makers, the question is no longer whether to act, but how to turn regulatory pressure into a source of competitive advantage.

Carbon costs are moving up the value chain

For most industrial companies, indirect upstream supply chain emissions – Scope 3 – account for between 60 and 99 percent of total carbon exposure. As the EU ETS tightens and CBAM extends its reach, the embedded carbon in sourced materials will become a direct cost factor, regardless of where a company sources its inputs. Industries with material-intensive products and complex global supply chains – such as automotive, electronics, construction, and consumer goods – face the sharpest exposure.

The regulatory environment adds further complexity. The European Union is advancing mandatory disclosure and carbon pricing at pace. The United States remains fragmented, with meaningful action concentrated at the state level. China is expanding its national emissions trading scheme and moving toward absolute emissions caps by 2027-2030. For multinational manufacturers, this patchwork of requirements demands a coordinated, forward-looking approach rather than a market-by-market response.

The economics of CO₂-optimized products are shifting

Under current cost structures, products designed for lower carbon footprints typically carry a cost premium compared to conventional alternatives – primarily due to the price of low-carbon materials and the process adjustments required for decarbonization. However, as carbon prices rise in line with regulatory changes, the economics shift materially. Roland Berger's cost forecast models point to a clear breakeven point: in the mid- to long-term, CO₂-optimized products become not only compliant but also economically competitive.

A case study of a European electric motor manufacturer illustrates this dynamic. Without action, carbon certificate costs alone could add approximately EUR 195 per motor by 2035 – a 13 percent increase in unit cost. By acting across three levers – incremental material substitution, redesigned product architecture, and supply chain restructuring – CO₂ reductions of 60 to 75 percent of the embeeded upstream supply chain emissions are achievable. The challenge is that product development cycles span multiple years, meaning that decisions made today will determine a company's carbon cost exposure well into the 2030s.

What best-practice companies are doing differently

Based on in-depth interviews with senior executives across the automotive, mechanical engineering, household appliance, and power tool sectors, Roland Berger has identified five practices that distinguish best-in-class organizations in product carbon footprint management.

Leading companies anchor CO₂ reduction targets in corporate strategy – not as a compliance exercise, but as a core business objective. They establish governance structures that embed sustainability across procurement, product development, and controlling. They invest in standardized data management systems to enable reliable product carbon footprinting, especially for Scope 3 emissions, where supplier data quality remains a persistent challenge. And they integrate CO₂ criteria into supplier selection and contract negotiations, treating supply chain decarbonization as a form of long-term risk management.

Critically, the most impactful lever is early integration of CO₂ targets into the product development process. Companies that apply eco-design principles from the outset – using digital tools to evaluate trade-offs between cost and emissions at the design stage – are better positioned to balance sustainability and profitability as carbon pricing intensifies.

The full report outlines seven concrete steps for companies seeking to translate regulatory pressure into strategic action – from dynamic target setting and portfolio-wide CO₂ assessments to supplier engagement and digitalization within product lifecycle management. Organizations that embed CO₂ management into product and supply chain decisions now will be better positioned to meet regulatory demands, protect margins, and gain a durable competitive advantage in a carbon-constrained market.
