Environment and sustainability

Environmental certifications

Environmental certifications are not just a requirement for us, they’re an opportunity to demonstrate our contribution to environmental protection and the sustainable use of resources – as well as to also share what we’re doing in that regard with our business partners. These certifications may at first glance seem like compulsory tasks, but for us they are an opportunity to live up to our own high standards. We’re not only committing ourselves to compliance with regulations, but also to going above and beyond to make a positive impact on the environment. Our motivation is to actively protect the world in which we live and to continuously improve our practices.



EMAS - Environmental statement

The sustainability report is also partly used as an environmental statement for EIAAS certification. We are reporting on the figures from 2020/2021, which relate to the areas of HERING Sanikonzept, HERING Systeme and HERING Bahnbau. The figures are verified by experts.

DNK - German Sustainability Code

In November 2018, the company published the first declaration in accordance with the German Sustainability Code (DNK). Thanks to the current publication, our sustainability performance including 2020 is transparent and comparable, which is confirmed by the DNK signet. The DNK is a voluntary standard for reporting on sustainability aspects and is published by the German Council for Sustainable Development (RNE).


HERING had its sustainability performance evaluated again in 2023 by the EcoVadis rating agency and received the "Gold" award. EcoVadis operates a collaborative platform that provides CSR ratings of suppliers for global supply chains.

UN Global Compact

HERING has committed itself to compliance with the ten principles of the UN Global Compact. These principles are set out and formulated in our Code of Conduct for customers, suppliers and employees. They consequently form the framework for our cooperation. We expect our business partners to adhere to these principles just as we do. We have our suppliers and subcontractors sign this responsibility towards people and the environment in a Code of Conduct.

Allianz pro Schiene / Pro-rail alliance

HERING is a supporting member of the ‘Allianz pro Schiene’ (‘Pro-Rail Alliance’) in Germany. The ‘Allianz pro Schiene’ represents companies from the entire rail sector and promotes rail as a safe and environmentally-friendly mode of transport.
