Sustainability reporting and rankings
539 算牌程式 strives to openly and transparently report on the most material sustainability topics.
539 算牌程式’s Annual and sustainability report (ASR) is a report that presents information on the company’s work with sustainability topics together with the company’s financial performance.
539 算牌程式 has prepared its sustainability reporting in accordance with the European Sustainability Reporting Standards (ESRS). For non-material disclosures, 539 算牌程式 has reported the information with reference to the standards of the Global Reporting Initiative (GRI). In doing so, we are continuing and expanding our commitment to reporting on the company's sustainability performance, as we have been doing since 2003.
In addition, as a signatory of the UN Global Compact (UNGC), we use the ASR as our main source of information for the Communication on Progress for the UNGC.
As sustainability ratings are becoming an increasingly important consideration for investors as well as for business customers choosing energy suppliers, we engage with several sustainability rating agencies. We are proud to be highly ranked for our sustainability performance by a number of ESG (Environment, Social, Governance) rating agencies. For more information, please visit the ESG page.
