The 30 companies in scope of the benchmark were assessed using the 2023 Methodology for the Seafood Stewardship Index. This methodology includes 48 indicators across four measurement areas of governance and strategy, ecosystems, traceability and social responsibility. The methodology and its indicators have been revised after the 2021 benchmark, based on stakeholder feedback.

Benchmark results are presented in individual scorecards that contain detailed assessments of performance. Information on company scores for each indicator can be found in a separate data set.

Approach to scoring and ranking

The benchmark scores each of the 48 indicators by using a set of criteria based on stakeholders’ expectations, the SDGs, the best available science, guidance from experts, and extensive research on existing initiatives and current practices. These criteria were then translated into indicator scoring guidelines. To accurately reflect companies’ leading and lagging practices, the scoring guidelines were finalised after the data analysis process was complete.

As the benchmark focuses on keystone companies in the seafood industry, the parent companies were the starting point and main unit of analysis. In scoring performance across different subsidiaries, we sought to assess performance at a group-wide level to ensure all relevant operations worldwide for a company were assessed and held accountable.

Data collection process

Relevant information for the benchmark was collected in the first instance using publicly available sources in the English language from company websites, including annual, sustainability, corporate responsibility and integrated reports. All companies in scope were also invited to directly participate in the data collection process by submitting information through an online survey through an eight-week data collection process in April-July 2023.
