Our Commitment to Sustainability

At SO/Vienna, our commitment to sustainability is at the heart of everything we do. We strive to make a positive impact on the planet by reducing our carbon footprint, minimising plastic use, and cutting down on food waste. Our Green Key certification is a testament to our dedication to environmental responsibility, and we invite you to be part of this journey.

What Green Key Certification Means

Green Key is a prestigious certification for environmental responsibility in tourism, awarded by the Foundation for Environmental Education (FEE). This certification signifies that our hotel adheres to strict sustainability criteria, including energy and water efficiency, waste management, and social responsibility. More than 5,900 hotels across 70+ countries hold the Green Key certification, setting a high standard for eco-friendly practices.

Our Green Initiatives

Supporting Local Charities: We actively support VinziRast, an organization that runs a hotel providing 15 beds for the homeless. Through our partnership, our staff contributes their time and skills to various tasks such as gardening, cleaning, and cooking. Our collaboration extends to sharing our sustainability knowledge, promoting a conscious lifestyle among VinziRast residents.

Sustainability Practices:

  • Energy and Water Efficiency: We manage our energy and water use meticulously to reduce our environmental impact.
  • Social Responsibility: We support fair labor practices and social programs for our team.
  • Local Environment Protection: Our efforts include initiatives to protect and enhance the local environment.


These practices are monitored through regular audits to ensure we maintain the standards of sustainability.
