Sustainability

The third generation now leads the Viessmann family business. We are therefore acutely aware of our social responsibility as well as that of safeguarding the natural resources for the future of generations yet to come. Measures to protect resources and the environment designed to promote sustainable actions are part of the corporate culture, as is the constant striving to improve efficiency along the entire process chain – from suppliers to end customers.

Sustainability strategy

The Viessmann sustainability strategy covers the entire value chain:

- Research & development
- Procurement
- Production
- Sales
- Logistics
- Product utilisation
- Treatment & recycling

Steering committee and working parties

Viessmann's sustainability strategy centres on the processes directly connected to the product lifecycle (see diagram). However, ecological aspects such as energy and material efficiency, harmful emissions and biological diversity, plus social topics such as HR structure, occupational health, further education and staff satisfaction, are also taken into consideration.

Splitting the activity areas between four working parties ensures complete coverage when it comes to the analysis:

- Strategy & controlling
- Products & processes
- Resources & infrastructure
- Employees & work environment

All activities are coordinated by a steering committee, which assigns tasks to the working parties and collates their results. The steering committee reports to the administrative board and prepares decisions.

Sustainability strategy in two phases

The operational implementation of the sustainability strategy is divided into two phases:

In the first phase, a comprehensive appraisal is carried out. This includes a description of the actual status in all relevant activity areas based on key figures. A comprehensive assessment of the demands and requirements of the most important contact groups (stakeholders), including customers, suppliers, employees, authorities, municipalities, clubs and associations, is also part of the actual analysis.

In the second phase, the results of the appraisal are collected and evaluated. Then standards are set out or adapted to form a company-wide specification. For the most important key figures (key indicators), targets with deadlines are defined and distributed to those responsible at the companies and members of the Viessmann Group.

PDCA cycle

All activities relating to sustainability are coordinated by a steering committee, which reports to the administrative board.

A controlling system ensures that achieving targets will be monitored and feedback will be requested. Setting targets (Plan), implementing measures (Do), monitoring and feedback (Check) and deriving new targets (Act) results in a continuous process ("PDCA cycle"), which leads to the improvement of sustainability of all products and processes at the company.

Sustainability Alliance [Allianz pro Nachhaltigkeit]

Viessmann has set up an online forum Sustainability Alliance for the general public. The homepage collects and bundle information about sustainable building, living and modernisation, which was previously incomplete or in a form that was too complex.

The long term objective of the Sustainability Alliance is firstly to achieve a sustainable approach to natural resources and secondly to ensure a CO2-neutral supply to buildings. The theme of sustainability should be introduced into and become an engrained part of the daily routine at the company.

Strategic "Efficiency Plus" sustainability project

With its strategic sustainability project "Efficiency Plus", Viessmann has shown that the energy and climate policy targets set for 2050 can already be achieved today. Through the use of commercially available technology, energy efficiency in particular has been significantly increased, as well as operational and material efficiency. Consumption of fossil fuels fell by two thirds, while CO2 emissions were reduced by 80 percent.

Klimaschutz-_und_Energieeffizienzgruppe.jpg

Viessmann is a member of the German Industry's Climate Protection and Energy Efficiency Group [Klimaschutz- und Energieeffizienzgruppe der deutschen Wirtschaft].

Viessmann is one of 15 companies making up the membership of the German Industry's Climate Protection Group. The Federal Ministry for the Environment, the Federal Ministry for Economic Affairs and the DIHK [Association of German Chambers of Commerce and Industry] established the partnership in 2009 - initially with four founding companies. Alongside Viessmann, berolina Schriftbild GmbH, ebm-papst Mulfingen GmbH and Prinovis GmbH were also selected by the initiators as companies setting an example with regard to energy efficiency and climate protection.

The member companies must meet the strictest criteria. For example, their company policy must include climate protection and energy efficiency and reports on performance/achievements must be regularly published. Consumption data and greenhouse gas emissions must also be systematically recorded and offset, and the issues of climate protection and energy efficiency must be an integral part of the training offered by the company.

The aim of the partnership for climate protection, energy efficiency and innovation is to tap into companies' existing climate protection and energy efficiency potential. Companies must also be committed to promoting the use of innovative technologies to exploit this potential during practical operations, and prerequisites should be set out for achieving the ambitious targets for climate protection and to increase energy efficiency in an economically viable way.
