The formula for successful energy measurement technology

Sustainability, innovation, and reliability

Three central themes are at the heart of Janitza's corporate philosophy:

  • Product quality
  • Efficient solutions in the energy sector and
  • an active contribution to sustainability

Only those who continue to develop and aim for high standards in all areas will be well positioned for the future. Janitza makes this claim and strives for a holistic continuous improvement process.



Janitza pursues this high standard by implementing various management systems and complying with the most relevant standards. This is supplemented by self-imposed goals and targets.

The Janitza business card:

Efficiency and sustainability combined

An active contribution to environmental protection: “The Janitza path to a positive climate contribution”

A central aspect of Janitza's corporate philosophy is the responsible use of resources and the protection of our planet. For this reason, Janitza has been operating an energy management system since 2013 and an active CO₂ management system since 2022. The two management systems form the foundation of Janitza's sustainability strategy.

Protecting the environment and preserving our planet is one of the greatest challenges of our time. As a company that offers energy measuring devices and solutions for optimized energy use, Janitza feels a special responsibility. The company has therefore been actively committed to reducing its carbon footprint for many years. To achieve this goal, the company's greenhouse gas emissions (CCF according to GHG) are balanced annually whilst implementing reduction measures. This is supplemented by promoting climate protection projects for self-generated greenhouse gas emissions. A product carbon footprint does not exist at this time.

"Our goal is to reduce our greenhouse gas emissions to a minimum by 2030, primarily through efficiency and savings measures. We want to supplement these measures with supporting certified climate protection projects. For us, this is the Janitza way to make a positive contribution to climate protection."
