About the data
The WBA Ocean Benchmark measures and ranks the world's most influential companies on their efforts to halt and reverse nature loss in marine ecosystems, tracking how companies manage their impacts on ocean biodiversity, marine habitats, and the communities and workers dependent on healthy seas. The 2026 edition is WBA's first Ocean Benchmark, assessing 125 companies across key sectors dependent on oceans, including seafood, maritime transport, offshore wind energy, shipbuilding, port operations, apparel, and chemicals. Companies are assessed on 47 indicators across four measurement areas: governance, ecosystems and biodiversity, social responsibility, and core social indicators. The benchmark builds on WBA's Nature Benchmark and the former Seafood Stewardship Index, and its methodology was developed with input from more than 50 stakeholders including ocean communities, companies, scientists and civil society, with human rights and social impacts kept at its core alongside nature-specific concerns.

Methodology
Impact materiality assessments allow companies to identify and prioritise their most
significant environmental, social and governance impacts. Embedding the results into their
sustainability strategy ensures that companies address these critical areas effectively, enhancing their
long-term resilience and aligning the company’s operations with the SDGs.
Research Guidance:
The company must conduct an impact or sustainability materiality assessment and meet both of the following aspects:
The company must disclose material impacts across its operations and value chain.
The organization must describe the criteria, sources or evidence it has used to identify and judge the materiality of the impacts. It must be clear that identified material sustainability impacts are based on actual or potential impacts, not merely the result of stakeholder preferences.
Examples of criteria:
Magnitude of impact
Likelihood of impact
Duration of impact
Severity or irreversibility
Examples of sources and external standards and frameworks:
Publicly available company data and reports
Academic and scientific research
Industry best practices
NGO reports
Global Reporting Initiative (GRI): Provides guidelines for materiality assessments and impact reporting
Sustainability Accounting Standards Board (SASB): Industry-specific standards for material sustainability issues
Task Force on Climate-related Financial Disclosures (TCFD): Focused on climate risks and impacts.
Task Force on Nature-related Financial Disclosures (TNFD): Focused on environmental risks and impacts
United Nations Sustainable Development Goals (SDGs): Identifies key global challenges that businesses can align with.
Guidance from regulatory bodies (e.g., European Commission‚s Corporate Sustainability Reporting Directive)
Types of evidence:
Scenario and impact modelling
Third-party audits
Benchmark data
Quantitative data: e.g. measurements
Qualitative data: e.g. interviews, case studies
