EWE announces Sustainability Strategy 2030 for its network area; Scope 3: upstream 50%, downstream 65%

As of July 2026 Sustainability strategy 2030

» To us, sustainability means thinking in decades when it comes to key issues — and acting in the interest of future generations. Our business decisions are guided by the aim to create real value for people, protect the planet and its resources, and generate societal benefit for all our stakeholders. We are convinced that sustainable success can only be achieved if we contribute positively from an economic, environmental, and social standpoint. We consider it self-evident to take on this responsibility. For us, sustainability is not a mere obligation - it is an integral part of our strategic direction, both internally and externally, and deeply rooted in our corporate culture. We aim to set strong examples and enhance sustainability awareness not only within EWE but also across the energy sector and society at large. Our sustainable orientation is guided by the United Nations Sustainable Development Goals. « Sustainability Strategy 2030
