DEME

DEME aims to achieve climate-neutral operations by 2050, focused on Scope 1 and Scope 2 emissions. This should be treated as an operational climate-neutrality target, not as a fully SBTi-validated Scope 1, 3 corporate net-zero target. DEME also states that it supports the IMO’s shipping pathway toward net-zero GHG emissions around 2050.

Climate-neutral operations 2050 (Scope 1+2); not full-Scope SBTi-validated.

DEME’s clearest interim target is to reduce GHG intensity by 40% by 2030 versus a 2008 baseline, aligned with the IMO strategy. This is particularly relevant for marine / dredging benchmarking because the target is fleet- and work-intensity based, not a simple production-tonne metric.

40% GHG intensity by 2030 vs 2008 baseline; IMO-aligned.

DEME reports Scope 1, Scope 2 and Scope 3 emissions in its sustainability statements. The values previously identified for 2025 are: Scope 1: 810,400 tCO₂e, Scope 2 location-based: 2,033 tCO₂e, Scope 2 market-based: 781 tCO₂e, and Scope 3: 1,422,190 tCO₂e. The wording should note that Scope 3 coverage has improved, so year-on-year comparability is affected by methodology and data-quality expansion. DEME’s strategy also explicitly recognises mitigation of value-chain emissions as a priority.

Scope 1, 2 and 3 reported; Scope 3 coverage expanded in 2025.

DEME is not a conventional mining / aggregates producer; its equivalent responsible-extraction evidence sits in sustainable marine solutions, dredging and infrastructure, environmental remediation, Nature-based Solutions, and project-level sustainability governance. DEME describes its sustainability strategy as two-dimensional: “Explore” sustainable business solutions and “Excel” in operational sustainability. Its sustainability page states that Nature-based Solutions can create positive ecological value, restore habitats, strengthen coastlines and enhance biodiversity.

Explore/Excel strategy; Nature-based Solutions; project-level governance.

DEME does not disclose a mining-style production intensity such as kgCO₂e / tonne extracted. The most relevant equivalent is fleet GHG intensity per unit of work, such as per dredged cubic metre or installed megawatt. At broader corporate level, DEME also reports GHG intensity relative to revenue; the 2025 figure previously identified was 538 tCO₂e per € million revenue, although this increased partly because Scope 3 coverage improved.

GHG intensity 538 tCO2e/€M revenue; rose with Scope 3 expansion.

DEME’s operational Scope 1 and 2 location-based emissions decreased from 970 ktCO₂e in 2024 to 812 ktCO₂e in 2025, equivalent to around a 16% reduction. However, total GHG emissions increased from 2,010,869 tCO₂e in 2024 to 2,234,623 tCO₂e in 2025, mainly because Scope 3 coverage was expanded and refined. For benchmarking, this should be written as: operational emissions decreased, but total reported footprint increased due to improved Scope 3 coverage.

Operational Scope 1+2 -16% YoY; total footprint up due to Scope 3 expansion.

DEME does not provide a conventional corporate water withdrawal / consumption / discharge table in the reviewed 2025 sustainability material. For DEME, water relevance is more directly linked to marine water quality, dredging, sediment management, turbidity, coastal works, flood protection and remediation, rather than freshwater consumption. This should therefore be marked as not disclosed in conventional water-volume format / not the most material metric for this business model.

Conventional water table not material; marine water quality is the relevant lens.

DEME’s water-quality evidence is project- and activity-based rather than table-based. It is relevant through dredging, remediation of contaminated sites, sediment management, coastal protection and flood-risk infrastructure. DEME’s taxonomy-aligned project assessment uses documents such as Environmental Impact Assessments, Climate Change Resilience Analyses, work plans and permits to assess environmental criteria. This is useful for marine benchmarking, but no consolidated effluent-quality table was identified.

Project-level EIAs and CCRA; consolidated effluent KPI not disclosed.

DEME does not disclose a simple number of sites in or near protected / high-biodiversity areas in the reviewed materials. However, biodiversity is addressed through the double materiality process, project environmental assessments and Nature-based Solutions. DEME’s sustainability page states that its Nature-based Solutions aim to create positive ecological value, restore habitats and enhance biodiversity. This is good qualitative evidence, but sensitive-area exposure is not quantified.

Double materiality and Nature-based Solutions; site exposure not quantified.

This metric is highly relevant because DEME operates in dredging, seabed works, land reclamation, offshore wind construction, subsea cable installation, marine infrastructure and environmental remediation. DEME’s Annual Report page describes the group as active across Offshore Energy, Dredging & Infra, Environmental and Concessions, and notes that Dredging & Infra continued to win marine works and maintenance dredging projects in several geographies. However, DEME does not disclose one consolidated KPI for seabed area disturbed, dredged area or habitat footprint.

Active across dredging, offshore, environmental; consolidated KPI absent.

DEME’s equivalent to rehabilitation / restoration is strongest through environmental remediation, Nature-based Solutions, coastal resilience and habitat restoration. The Annual Report page confirms that DEME has an Environmental segment, with 2025 turnover of €272 million and an order book above €400 million, reflecting its remediation and environmental project base. DEME’s sustainability page also frames Nature-based Solutions as a way to restore habitats and build resilient coastlines.

Environmental segment €272M turnover; remediation & coastal resilience evidence.

Formal mining-style tailings / TSF / GISTM evidence is not applicable to DEME. The closest equivalent is dredged sediment, contaminated soil / sediment remediation, seabed material handling and non-hazardous waste sorting / material recovery. For scoring, this should not be treated as a missing mining metric, but as not applicable; sediment and remediation management are the relevant substitutes.

Tailings not applicable; sediment remediation and material recovery substitute.

DEME does not provide a simple group-wide waste recycling or diversion rate in the reviewed materials. However, circularity evidence is present through environmental remediation, material recovery, sustainable project design and operational sustainability governance. DEME also participates in sustainability initiatives linked to offshore wind and circular economy, but the benchmark should record this as circularity evidence present; consolidated waste KPI not clearly disclosed.

Circular evidence via remediation and material recovery; group KPI absent.

DEME provides environmental management and permitting evidence through EIAs, work plans, permits, Climate Change Resilience Analyses and EU Taxonomy DNSH-style project assessment. However, no a simple headline number for environmental fines, spills, permit breaches or major environmental incidents in the reviewed disclosures was identified in reviewed public materials. The safest wording is: environmental management and permitting evidence present; headline incident / fine count not clearly identified.

EIAs, permits, EU Taxonomy DNSH; headline incident/fine count not identified.

DEME has increasingly structured supplier due diligence. It uses a Code of Ethics and Business Integrity for Business Partners, includes business-partner integrity principles in supplier contracts, operates a third-party due diligence procedure for suppliers, subcontractors, clients and partners, and uses a supplier assessment tool to evaluate ESG risks. In 2025, DEME continued using this tool with core and strategic suppliers, covering more than a quarter of annual procurement spend, and approved a dedicated Sustainable Procurement Policy. DEME’s sustainability page also shows a formal sustainability governance structure involving the Board, Executive Committee, Sustainability Board, Sustainability Team and process owners.
