Environmental protection

We take responsibility for our environment

As a society, it’s never been clearer to us how strongly we need a pristine environment and how important it is for us to protect it. Viessmann bears a special responsibility as a leading international manufacturer of energy systems. We act accordingly and allow ourselves to be measured by the promises we make. The most recent information about how we take responsibility for the environment can be found in our 2023 Viessmann Sustainability Report.

Viessmann has been putting the concept of integrated environmental protection into practice for decades. Our entire value chain is geared towards it. Our brand values have served as the foundation for establishing an environmental policy for the company from which specific goals can be derived. Thanks to our environmental management system, we can realize this environmental policy and guarantee compliance with external and internal environmental standards.

We want to do more than just adhere to legal regulations and environmental protection requirements for companies. Our work thus focuses on continually improving our environmental management system. We ensure that living spaces remain worth living in for generations to come.

The principles of action of our environmental policy

The Viessmann Executive Board has defined binding principles of action for all employees.

We improve our environmental performance

The observance of all legal regulations is our minimum standard. In order to continuously improve environmental performance, we make use of the best technology available, as long as it is economically justifiable.

We avoid polluting the environment

All of our activities, processes, operating resources, and our new products and services are checked for their environmental compatibility before they are used. We regularly assess the impacts on the environment and minimize them.

We conserve resources

We use raw materials in a resource-saving manner and employ energy as efficiently as possible. Unavoidable emissions and waste are reduced to a minimum.

We think in terms of life cycles

Is that sustainable? This is the question we ask ourselves right at the very beginning – from the development of our products to their production, use, and disposal. We make sure to conserve resources during production. Our heat generators excel during ongoing operations thanks to high thermal efficiency and durability. At the end of their technical service life, Viessmann products are professionally recycled and valuable raw materials are looped back into the production and reusable material cycle.

We participate in the take-back schemes required by law in each specific market to ensure the return of old appliances. Since 1995, we have also cooperated with a nationwide waste disposal service provider and offered our customers in Germany the voluntary take-back of waste. We recycle our packaging in accordance with the valid regulations in place in the local markets. In Germany, we are part of a solution which was brought into being by industry, trade, and crafts back in the early 1990s to take back and recycle packaging from the plumbing, heating, and climate sector.

We want to maximize the reduction of hazardous substances. To do this, we take a hard look at our processes and products on a constant basis and improve them. The relevant regulations on hazardous substances stipulate bans, restrictions, and limit values on substances with which all suppliers must fully comply. All deliveries and services must be provided taking these prohibitions into consideration. Further information for suppliers can be found  here.

Information as per REACH regulation

The EU regulation REACH (Registration, Evaluation, Authorisation and Restriction of Chemicals) regulates the obligations of producers when placing substances, mixtures and products on the market. In addition to data acquisition and registration of substances, these include the transfer of information along the supply chain.

Special obligations apply when products are placed on the market that contain "Substances of Very High Concern" (SVHC). These are substances which, due to their hazardous properties, may be subject to authorisation after further examination by the European Chemicals Agency (ECHA) and are included on the so-called "candidate list" (= candidate for the list of substances subject to authorisation according to Annex XIV of the REACH Regulation).

According to the information available from our suppliers, Viessmann products may contain the following SVHC:

Aluminosilicate Refractory Ceramic Fibres-High-temperature insulation (cords, mats, plates, moulded parts
Lead7439-92-1Modules/components with lead as alloy component togetherwith copper (brass), iron, aluminium  

Our products do not pose any hazards unusual to the product when used as intended, taking into account the safety instructions in the product information and implementing the usual hygiene measures (wearing personal protective equipment, washing hands, etc.).
