How can I communicate our sustainable efforts after the certification with GreenSign?

Each company certified with GreenSign receives, in addition to the certificate naming the GreenSign level achieved, a bar chart on which the progress in the individual core areas of certification is transparently displayed. The more sustainable the company acts in an area, the further the bar extends in the respective area. This transparency allows customers and guests an open and credible insight into the company’s sustainability activities. The GreenSign logo, the barometer, an attractive and honest mission statement and an informative sustainability report can be presented on the company’s website and on all social media channels. Sustainability should always be communicated in a positive way and not associated with doing without. A carbon footprint also helps communicate the hotel’s conservation of resources. GreenSign offers the CO2 footprint and water footprint additionally and issues a corresponding certificate for it.

I am interested in sustainability, but unfortunately BIO products and straws made of wood are too expensive for me!

Sustainability does not have to be expensive! The first step is to strive for effective resource conservation, i.e. to use less water and energy and produce smaller amounts of waste. The costs saved in this way can, if desired, be invested in environmentally friendly products such as food, cleaning products or cosmetics in the next step. In the GreenCommunity you will also find many sustainable partners who offer special conditions for GreenSign certified companies. This way, you can still save a little on sustainable products.

How authentic is the assessment in the audit, how can you be accurately verified?
