Introduction to the report

This Sustainability Index is designed to facilitate the navigation of Boliden’s disclosure of governance, strategies, report parameters, sustainability topics and performance indicators. It includes references to Boliden’s environmental, social, and economic targets and results.

Defining report content and topic boundaries

The information contained in this report covers data from Boliden’s ten Business Units, from the Group’s head office and various staff functions, and from its sales offices. Environmental performance data is limited to Boliden’s ten operational Business Units as they represent Boliden’s significant environmental impacts.

During the reporting period, there were no significant changes in Boliden’s mining operations, smelting operations, supply chain, capital structure or capital formation. We are however expanding our zinc smelter in Odda, southern Norway. The expansion will enable Odda to almost double its zinc production and at the same time reduce carbon dioxide intensity.

Report content

The Sustainability Index provides stakeholders with relevant information about our governance, environmental and social impacts. These include topics directly connected to how Boliden conducts its operations, as well as topics that impact stakeholders and thereby Boliden’s social license to operate and ability to develop its business.

This report has been reviewed and approved by Boliden’s Group Management.

Reporting principles

The financial data presented in this Sustainability Index is drawn from Boliden’s audited annual accounts. The Boliden Group reports in Swedish kronor (SEK). Occupational health and safety data and environmental data, including energy-­related data, is collected monthly from the units and consolidated at Group level. Social sustainability data is collected on a quarterly or annual basis from the operations and consolidated at Group level. Metal emissions to air and discharges to water are measured in metal equivalents in alignment with the Natural Capital Protocol (NCP) framework.

More detailed measurement techniques, calculation methods, and assumptions are reported in connection with relevant indicators.

External assurance

Our policy is to use external assurance to ensure the high quality and credibility of the information published in the Sustainability Index. The Sustainability Index and the Annual and Sustainability Report have therefore been subject to external limited assurance by the Auditor in accordance with ISAE 3000, as issued by the International Federation of Accountants (IFAC). The auditor’s limited assurance report is included in this report. Organizational profile and key performance data are presented in Boliden’s Annual and Sustainability Report 2022.
