Sustainability Report

Foreword It gives me great pleasure to share our 2021 Sustainability Report and Sustainability Strategy 2028. This year the Sustainability Report is prepared according to the recognized GRI 2021 reporting framework as our aim is to meet the highest transparency standards. The Strategy sets out our long-term commitments to run a sustainable business in balance with nature and inclusion for all. I am proud to say that many of the themes in this strategy have been embedded within our corporate culture for years and have created significant value for the company and its stakeholders. In a world that is experiencing increasing economic, social and environmental pressures, we need to ensure that resilience remains our guiding principle. This means ensuring that our business model remains flexible, responsive and, most importantly, sustainable in the long term. What the last few years have taught us is that companies have a significant role towards preventing environmental and social risks around us. We all have the responsibility to take action and the private sector has a crucial role to play in driving the transition to a better, cleaner and more inclusive future. I firmly believe that the key to generating long-term value for all our stakeholders is to act responsibly and with integrity across every aspect of our business. This will remain the foundation of our decision-making and strategy going forward. We aim to be a force for good and continue to strengthen the positive impacts on what matters the most to us – our planet and its people. Not only do we want to show our dedication to the Bulgarian society and the world by becoming more sustainable, but we also want to show progress by committing to report annually on the targets set in this Report. Yettel’s Sustainability Strategy will guide our approach to environmentally sustainable practices, empowerment of our people, digitalisation of society, promoting a culture of integrity, transparency and accountability.
