Sustainability Strategy

Subsea7’s sustainability strategy is guided by a materiality assessment to ensure we prioritise the risks and opportunities that are of greatest importance to our stakeholders, as well as those that could have a material impact on our business and the world around us.

Our materiality assessment

In 2019, we conducted a materiality assessment in collaboration with an independent specialist sustainability consultant. We gathered broad stakeholder feedback from our clients, our shareholders and our people and we observed the wider industry and scientific reports. This information was then analysed in detail to create a longlist of key topics. All the topics we discussed are important to us, but the longlist focused on those that apply to a wide range of stakeholders and have the greatest long-term impact on our future.

Outputs of the assessment are displayed on adjacent matrix.

During 2023, we have further aligned our materiality approach with the framework proposed by the EU Corporate Sustainability Reporting Directive (CSRD) by conducting a double materiality assessment. The results demonstrated a high level of convergence to the sustainability areas we have been focusing on since 2019. Further updates to our website will follow to reflect the latest double materiality assessment outcomes and the resulting material topics.

In order to remain focused on the most material topics going forward, we intend to carry out a refresh of our materiality assessment every three years.

Our stakeholders

Our stakeholders are important to us and we are aligning with their expectations on sustainability.


Our society defines what is acceptable and what is expected in terms of corporate behaviour. We have a duty to respect the communities where we operate and the environments, we work in.


Our clients expect us to operate safely, efficiently, cleanly and with integrity.


Our people expect us to keep them safe, treat them with respect and be a good employer.


Our shareholders expect us to be fair, balanced and transparent in our interactions with the market around our approach to environmental, social and governance-related risks and opportunities.
