Heidelberg Materials Cuts CO₂ per Tonne of Cement to 512 kg and Raises Sustainable Revenue Share to 37% in 2025 Results

Introduction: why these numbers matter for construction-sector decarbonisation

With cement-making responsible for roughly 7% of global CO₂ emissions, every kilogram saved per tonne of product ripples through infrastructure value chains. Heidelberg Materials’ Annual and Sustainability Report 2025, released in March 2026, provides the first audited data set that simultaneously complies with the EU’s Corporate Sustainability Reporting Directive (CSRD), IFRS S-1/S-2 and the Task-force on Nature-related Financial Disclosures (TNFD). The headline takeaway: specific net CO₂ emissions fell 3% to 512 kg per tonne of cementitious material, while the share of revenue coming from “sustainable” products jumped 1.9 percentage points to 37%. Record financial performance—€21.5 billion revenue (+1.4%) and €3.4 billion result from current operations (+5.5%)—shows that profitability and deep decarbonisation can move in tandem.

Understanding the development: what was measured and when

The reported intensity metric covers Scope 1 emissions from Heidelberg Materials’ 159 cement, grinding and clinker plants worldwide. Data were gathered with the company’s in-house Climate-Track tool and verified by an external auditor under ISAE 3410. “Sustainable products” are defined through internal eco-labels (evoBuild®) that meet at least one of three thresholds:

• ≥30% lower cradle-to-gate CO₂ footprint than the regional industry average;
• ≥20% recycled content by mass;
• production in a facility equipped with carbon-capture technology.

Examples include evoZero® (near-zero cement from Brevik), calcined-clay cements produced in Ghana and forthcoming volumes from the Padeswood, Wales CCS project.

Key findings and 2025 milestones

Carbon performance

• 512 kg CO₂/t cementitious material, down from 528 kg in 2024 and 42% below the 1990 baseline.
• Absolute group-wide cement-related CO₂ stayed flat despite volume growth, indicating genuine efficiency gains rather than output contraction.
• Brevik CCS captured its design load of 400,000 t CO₂; pipeline injection into offshore saline aquifers ran at 98% uptime.

Financial and capital efficiency

• Record 10.4% return on invested capital (ROIC), up 0.5 ppt, beating the cost of capital by 3.1 ppt.
• Earnings per share climbed to €10.92, supporting a proposed dividend of €3.60 per share and the third tranche of an active buy-back programme.
• Sustainable-product turnover now €7.95 billion, growing at double the rate of conventional lines.

Operational footprint

• 48,973 employees across almost 50 countries; lost-time injury frequency down to 1.2 per million hours.
• Share of renewables in electricity mix reached 48%, aided by 220 MW of new solar rooftops and a 50 MW wind park in Texas.

Methodology and levers behind the 3% intensity drop

Heidelberg Materials pulled four complementary levers:

1. Clinker substitution: Group clinker factor declined 0.8 ppt to 73.4%, driven by 1.6 Mt of calcined clay and 0.9 Mt of limestone calcined clay cement (LC³) sold in West Africa and Poland.
2. Alternative fuels: 37% of kiln thermal energy now from biomass, refuse-derived fuel and hydrogen-enriched waste gases; coal share fell below 50% for the first time.
3. Energy efficiency: The Transformation Accelerator Initiative—a company-wide cost and carbon programme—delivered €280 million savings in 2025, on track for the €500 million/yr target by 2026. Remote-operations centres such as HROC in Dallas optimise grinding circuits and precalciner settings, trimming 2–4 kWh of electricity per tonne.
4. Carbon capture and utilisation: Brevik’s 400 kt stream and a 40 kt pilot in Górażdże, Poland, using the patented ReConcrete carbonation process, jointly removed 0.44 Mt of CO₂ from plant boundaries.

Implications for the cement and concrete value chain

By proving that sub-520 kg CO₂/t cement can coincide with double-digit ROIC, Heidelberg Materials erodes the long-held belief that low-carbon cement is a stranded-cost story. Customers gain access to verified low-embodied-carbon concrete, helping them meet Scope-3 reduction pledges. Suppliers of supplementary cementitious materials, CCS technology vendors and renewable-power developers receive a price-signal that demand for their solutions is accelerating. Competitors face rising investor pressure to disclose comparable CSRD-aligned metrics or risk capital reallocation.

What this means for policymakers and investors

Policy

• The EU Innovation Fund has already shortlisted four additional Heidelberg CCS projects (Belgium, Italy, Germany and Norway), signalling regulatory confidence in full-scale deployment.
• The UK’s contract-for-difference model for Padeswood offers a reference carbon price of ~£80/t CO₂, informing future UK ETS price trajectories.

Capital markets

• Heidelberg’s share price exceeded €200 for the first time, outperforming the STOXX Europe 600 Construction index by 28%.
• ESG index providers upgraded the firm to “AA” (MSCI) and added it to the STOXX Global Climate Leaders, channelling passive inflows.

Challenges and next steps toward 2030

Even with rapid progress, the company must still close a 212 kg gap to reach its 2030 target of 300 kg CO₂/t. Scaling CCS outside Europe (India, U.S. Midwest) hinges on storage permitting and public financing. Securing growing volumes of biomass and waste-derived fuels without triggering unintended land-use change remains tricky. Finally, customer willingness to pay a green premium is uneven; regulatory mandates such as France’s RE2020 or the Netherlands’ forthcoming maximum clinker factor are critical market makers.

Conclusion: a material difference in the making

Heidelberg Materials’ 2025 scorecard demonstrates that deep decarbonisation and robust shareholder returns can coexist. A 512 kg CO₂ footprint positions the company among the sector’s top quartile, while a 37% revenue share from sustainable products proves that low-carbon solutions are moving from niche to mainstream. With Brevik CCS running at full capacity, Padeswood under construction and a pipeline of EU-backed projects, the pathway to 300 kg by 2030 appears credible. If replicated globally, the intensity trajectory could shave roughly 0.5 Gt CO₂ annually from cement-related emissions—an essential brick in building a net-zero world.
