In January 2021 Ethical Consumer searched the Viessmann company website for details of the company's environmental reporting. Ethical Consumer was looking for a recent report which contained quantified future targets and independently verified environmental data.
The company discsussed some things on its website, and also linked to a sustainability report, but it was from 2015.
It discussed raw materials, energy, recycling, end of life disposal methods, waste and water. However, there was no discussion of toxic chemicals and so it was not held to have a reasonable understanding of its environmental impacts.
No quantified future targets could be found. The environmental data presented did not seem to independently verified.
Overall, Viessmann therefore received Ethical Consuemr's worst rating for Environmental Reporting.
