A.P. Møller - Mærsk A/S sustainability score: 29/100

Maersk reports 33,939 kt Scope 1 and 356 kt Scope 2 market-based emissions for 2024 in its CSRD-aligned Integrated Annual Report. Data follows GHG Protocol with third-party assurance, multi-year tracking since 2019, and granular breakdown by segment including both location and market-based Scope 2 variants.

Maersk reported 49,232 kt Scope 3 emissions across 12 of 15 GHG Protocol categories in 2024. Roughly 60% of top 200 customers have committed to or set science-based targets. An Emissions Dashboard helps customers track supply chain emissions. Full Scope 3 verification remains limited.

Total emissions rose 7.57% from 2023 to 2024 (77.7 to 83.6 Mt CO₂e) due to Red Sea rerouting and fleet utilisation. EEOI reached record low of 10.8 g CO₂/tonne-nm in 2025, but absolute emissions have not declined from the 2022 baseline of 82.4 Mt. Scope 3 rose further in 2025 to 51,183 kt.

APM Terminals renewable electricity usage reached 62% in 2025 from 46% in 2024, targeting 100% by 2030 (SBTi validated). Maersk operates 19 dual-fuel green methanol vessels by 2025. However, marine fuel oil dominates vessel propulsion energy consumption, leaving the overall energy mix heavily fossil-dependent.

Maersk performed initial LEAP framework assessment for nature issues. Company received B grade from Whale Safe for voluntary speed reductions, supports ocean cleanup initiatives, and complies with ballast water regulations. All owned vessels are ISO 14001 certified. However, no quantified biodiversity metrics or TNFD-aligned targets have been published.

Maersk completed a Global Waste Assessment for Logistics & Services and APM Terminals operations. Company piloted circular mooring ropes with C-Loop and developed cradle-to-cradle vessel material passports for end-of-life recycling. Founding member of Ship Recycling Transparency Initiative. Quantified circular economy targets and waste reduction metrics remain limited in public disclosure.

Maersk developed enhanced water consumption reporting methodologies and identified drought/water stress as a terminal climate risk in its 2022 assessment. Context-based water reporting referenced. Quantified water footprint data, reduction targets, and detailed water management metrics are not prominently disclosed in publicly accessible materials.

Maersk became the first company with SBTi-validated targets under Maritime Guidance in early 2024. Targets include 34.7% absolute Scope 1 and 21.9% Scope 3 reductions by 2030 (from 2022 base), and 96% Scope 1+2 and 90% Scope 3 by 2040. Net-zero by 2040 across full value chain with reduction-first approach.

Maersk published its first CSRD-aligned Integrated Annual Report for 2024. Dedicated Head of Corporate Sustainability reports quarterly to executive leadership and Board of Directors. Company discloses TCFD/CSRD, reports to CDP, and publishes industry association membership reviews. Executive compensation linkage to sustainability targets is not prominently documented.

NewClimate Institute (2022) identified Maersk among only three companies committing to >90% value chain decarbonisation. InfluenceMap rates Maersk as supportive of science-aligned climate policy (2023-25). However: received B (not A) from Whale Safe on speed compliance; Vice raised greenwashing questions about green methanol scalability; serves on International Chamber of Shipping board with historically mixed climate positions.
