Our LEAP to Net Zero

Viessmann Climate Report 2021

In our Viessmann Climate Report we explain our climate strategy "LEAP to Net Zero". It builds upon four pillars for action: Lead, Empower, Advocate and Partner – "LEAP". Together with our partners and stakeholders, we want to leapfrog, in other words take a giant step forward, towards reaching net zero in our own operations and the systems that we are a part of.


Climate Science

Science warns us that humankind is changing the climate of Planet Earth. Through greenhouse gas emissions, we are heating up the planet and have already done so by 1.2 degrees since the start of the industrial era. Climate science projects that we will reach an increase of 4 to 5°C if we do nothing by 2050. We only have 300 Gt left today in our planetary carbon budget to limit global warming to 1.5°C. To stay within the budget, every country and every business needs to reach net zero as soon as possible. Net zero refers to a state in which the greenhouse gases going into the atmosphere are balanced by removal of the same amount of greenhouse gases out of the atmosphere. A country or business that reaches net zero is no longer climate negative but climate neutral. Reaching net zero and becoming climate neutral is what we at Viessmann aim to achieve with our climate strategy.

Our response to climate change

Looking at the urgency of climate change and the Viessmann heritage of embracing change makes it crystal clear: we can and must do more to scale sustainable heating, ventilation, cooling solutions for everyone. We can and must do more to make our own operations future-fit. We can and must do more to lead a systems transformation towards net zero buildings. And this is what we aim to do through our climate strategy “LEAP to Net Zero.”

Our LEAP to Net Zero

The envisioned future that we plan to achieve through our climate strategy “LEAP to Net Zero”.


We lead by example.

Our operations will be net zero, regenerative, circular and embedded in healthy ecosystems.

We empower people to act.

People will be empowered to radically reduce their CO2 emissions and be prosumers – through our many climate solutions.

We advocate to foster a movement.

Employees and partners will be climate heroes. Our brand will be the trusted partner for climate action. We will be the thought leader for climate policies.

We partner to scale impact.

Suppliers and partners will be empowered to radically reduce their CO2 emissions. The region around our headquarters. Our venture and innovation activities will be net zero.   

Our climate strategy to lead a systems transformation

Looking at our set climate strategy "LEAP to Net Zero" from a systems perspective shows that we lead change beyond our own operations. With our climate strategy we aim to transform ourselves and lead the transformation towards net zero buildings.

What does system transformation mean for the building sector? A transformed, net zero building system is characterized by three aspects:

  • Decarbonisation: Renewable energy is used as the primary input energy for all living space services
  • Decentralisation: Electricity and heat generation systems are more decentralized and interconnected with our buildings
  • Digitalisation: Electricity and heat production and consumption are optimized via digital solutions


Climate target for our own operations

In our climate strategy, we have committed that our operations will be net zero by 2050 (Lead). To get there, our first climate target is to reduce the emissions from our own operations by at least 48% in absolute terms by 2030 (Scope 1 and 2 GHG emissions compared to 2019 levels). This means a 75% reduction compared to 2005 despite our high growth.

Climate target for our value chain

Also, we commit that we will empower people, partners and suppliers to radically reduce their CO2 emissions (Empower, Partner). For the emissions reductions of supplying our materials and using our products, we set ourselves a second climate target: at least 55% reduction of Scope 3 GHG emissions in economic intensity terms by 2030 (compared to 2019 levels).

We used two globally recognized accounting standards Greenhouse Gas Protocol and the Science Based Targets initiative (SBTi; target validation still pending) - to ensure targets are in line with climate science to stabilize global warming at 1.5°C.
