Your sustainability is our concern.

Certified sustainability with GreenSign
GreenSign Team

Why we do this?

We want to encourage companies to commit to ecological, socially responsible and sustainable management by making meaningful changes and to live this with joy and conviction. Through sustainable and responsible management, businesses become more resilient and better able to compete in a rapidly changing marketplace.

By acting in an environmentally friendly way, you not only contribute to a more eco-friendly future, but you also address the needs of your customers. Furthermore, you position your company on the labor market with sustainable employee management and convince qualified personnel. This aspect is becoming increasingly important, as more and more employees want an employer who values sustainability.

How we do it?

We look closely. So closely that we have already certified more than 750 companies in 18 countries with GreenSign. This has enabled us to establish ourselves as the leading sustainability certification for the hotel industry in Germany.

Since 2021, we also certificate Offices and SPAs with GreenSign. In addition to sustainability, we offer health certification with GreenSign Health.

You are overwhelmed with the multitude of certificates?

We’re happy to help.

Our certification is not the only one on the market, we are aware of that. You wonder what we do differently than the others? Why our founder and CEO Suzann Heinemann created GreenSign, how GreenSign stands out from the crowd and why there is a need for certifications in the first place, you can find out best from herself.

Sustainability works everywhere.

We certify sustainability in these areas.

How you start with it?

Preferably immediately.

Credible certification helps to strengthen a positive image and thus offers a valuable competitive advantage. A conscious sustainable positioning supports hotels and companies in acquiring new guest and customer groups and retaining long-standing regular guests and customers. In addition, an environmental management system helps to effectively conserve resources, save costs and optimize internal processes. Certification brings your company numerous advantages, which we would like to present to you in detail here.

  • Raising awareness of cost and energy efficiency

  • Transparency towards all stakeholders

  • Optimized customer approach and development of new target groups

  • Satisfied and motivated employees

  • Networking Events

  • More visibility on the web and in the media

We don’t like it complicated.

That’s why we make it simple.
