Biodiversity in action
In 2024, St1 completed the Science Based Targets for Nature (SBTN) training under the UN Global Compact Finland initiative. This training provided essential methodologies for assessing biodiversity-related risks and opportunities. Using the SBTN Materiality Screening Tool, we conducted a high-level materiality assessment, further enhanced by desktop evaluations employing established tools such as ENCORE, the WWF Water and Biodiversity Risk Filter, and the CDP Water Watch. These assessments established a baseline for our double materiality assessment (DMA), ensuring alignment with leading standards and frameworks.
Additionally, in 2024 St1 initiated site-specific biodiversity mapping using the Integrated Biodiversity Assessment Tool (IBAT). This analysis allows us to identify critical biodiversity values across our operational landscape.
Our main activities to advance biodiversity in 2024
Increasing knowledge and access to biodiversity data
St1 completed the Science Based Targets for Nature (SBTN) training in 2024.
Mapping & monitoring
Using tools like ENCORE, WWF Risk Filters, and IBAT to assess environmental impact.
Impact & dependency evaluations
Strengthening our understanding of biodiversity risks across value chains.
Next steps in integrating biodiversity into our operations
Looking ahead, we are committed to advancing our biodiversity agenda through detailed impact and dependency evaluations targeting the most relevant value chains. We also plan to carry out site and project-specific assessments to strengthen our understanding and management of biodiversity impacts.

Environmental responsibility & resource management
At St1, environmental monitoring is an integral part of our refinery's environmental permits, ensuring compliance with regulations and minimizing ecological impact. As part of our commitment to environmental stewardship, we take immediate action to mitigate and remediate any environmental damage in the event of an incident. Our Gothenburg refinery holds ISO 14001 certification, ensuring that our environmental management system meets globally recognised standards for sustainability, continuous improvement, and compliance.
Water stewardship – Optimizing water use, ensuring compliance with strict environmental standards.
Pollution prevention – Proactively managing emissions, spills, and industrial waste.
Air emissions:
Sulphur oxides (SOₓ): Produced during the combustion of sulfur-containing fuels.
Nitrogen oxides (NOₓ): Emitted from combustion processes.
Volatile organic Compounds (VOCs): Released during fuel storage and distribution.
Particulate matter (PM): Generated from various operational activities.
Oil and chemical spills
Sustainable operations – Implementing governance policies that reinforce our commitment to environmental protection.
