Sustainability Index 2021

ABOUT THIS SUSTAINABILITY INDEX

Boliden has published information on its sustainability approach and performance since 2005. This Sustainability Index is prepared in accordance with the Global Reporting Initiative (GRI) Standards: Core Option. It also constitutes Boliden’s Communication on Progress (COP) and therefore contains references to Boliden’s performance in relation to the UN Global Compact’s ten principles; the Task Force on Climate-related Financial Disclosures (TCFD, supported by Boliden since 2019); the Sustainability Accounting Standards Board (SASB, supported by Boliden since 2021) and the International Council on Mining and Metals (ICMM, where Boliden has been a member since 2021) principles.

The 2021 Sustainability Index contains references to the Boliden 2021 Annual and Sustainability Report that discloses the Group’s value creation, operations, and risk assessment, including the sustainability perspective.

The Sustainability Index and the Annual and Sustainability Report have been reviewed by means of an external limited assurance engagement 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 2021.

Defining report content and topic boundaries

The information contained in this report, except for environmental performance data, 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 have been no significant changes in the smelting operations, the supply chain, or in the capital structure and capital formation. In mining operations, the Kylylahti mine was closed in November 2020 and reclamation work is ongoing. Boliden is expanding the 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

Boliden’s Sustainability Index has the ambition to provide Boliden’s stakeholders with relevant information about the company’s economic, environmental and social impacts. Boliden’s sustainability topics are presented in this report. 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 and Board of Directors.

Reporting principles

The financial data is drawn from Boliden’s audited annual accounts. The Boliden Group reports in Swedish kronor (SEK). Occupational health and safety and Environmental data, including energy-related data, is collected on a monthly basis from the units and consolidated at Group level. Social data has been 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

Boliden’s policy is to use external assurance to ensure the high quality and credibility of the information published in the Boliden Sustainability Index. The Sustainability Index has therefore been subject to external limited assurance by the Auditor.
