The Sustainability Report is prepared in conformity with the guidelines of the Global Reporting Initiative, GRI-G3, and this year it has reached the maximum application level: A+.

The Global Reporting Initiative (GRI) is a multi-stakeholder process for development and disclosure of guidelines for sustainability reporting. The guidelines set out principles and indicators for reporting on the economic, environmental and social dimensions and represent a standard for content to assist in the preparation of the Sustainability Report, enabling comparability over time and between similar organisations. In addition to establishing principles for the preparation of sustainability reports, the GRI-G3 guidelines define content which is developed under: strategy and analysis, profile of the organisation, report parameters, govemance, stakeholder inclusiveness and economic, environmental and social performance indicators.
