Every single person can have a positive impact on the world we live in. However, we need big changes in the economy, society, consumption and behaviour to save our planet. In order to achieve the UN SDGs, major steps must be taken within industries, organisations and companies. Holger Sigmund advises tourism & hospitality businesses and destinations for their sustainable development and performance.


Holger consistently uses public transport and enjoys cycling to commute within Zurich. His car, a Volvo that is over 25 years old, is hardly used and publicly shared here. He tries to live more sustainable in general by buying less, avoiding single-use plastic, switching his consumption to local and/or organic, mostly vegetarian products, controlling and reducing emissions, respecting nature and offsetting his remaining carbon footprint annually with myclimate


Global Sustainable Tourism Council

The GSTC establishes and manages global standards for sustainable travel and tourism, known as the GSTC Criteria. They are the result of a worldwide effort to develop a common language about sustainability in tourism and may be adapted to local conditions. I am an organisation member and I have successfully completed the STTP with the 'Professional Certificate in Sustainable Tourism'.

GreenBuzz Zurich

GreenBuzz is a global network of sustainability professionals with chapters in Zurich, Bern, Geneva, Amsterdam and Berlin. The network's mission is to empower sustainability professionals across sectors to drive sustainability forward in business & society. I am a member of the zurich chapter.


I am a member of Greenpeace Switzerland because I find it very important that an international powerful organisation help us to care about our environment and call attention to the problems of climate, ocean, forests and foods.

Quartierhof Wynegg

As a family we are member of the Quartierhof Wynegg, a Zurich farm operated by residents in several working groups. The farm sells some products, offers a lunch for school children and rents a space for groups. And it is a natural, green hideaway within the city. For more information (in German only) click here:

Bangladesh Projects

Since 2008, I have supported and was member of the foundation of our own project in Southern Bangladesh on the Island of "Bhola" together with an international team from UK, Sweden, Austria, Liechtenstein and Spain. The project now is able to stand on its own feet and is still supported by the London based foundation Bhola's Children.

Rishilpi, a long term and very experienced organization, was our local partner in Bangladesh from the beginning on and I still support this very transparent and reliable organisation. The founders Laura and Enzo plus Monica in her Milano based office just do a wonderful job and today more then 90.000 people around Satkhira directly and indirectly benefit from the projekt. If you are interested in helping the very poor people in Bangladesh, please feel free to e-mail me.
