Our Responsibility
Heraeus Covantics manufactures high-purity quartz glass, ceramics, and composite materials. Our manufacturing processes are energy-intensive—for example, due to the melting of quartz sand at very high temperatures. This entails a special responsibility, and we are implementing measures to use energy and resources more efficiently.
“For us, sustainability isn't a one-time task, but rather a mindset that we must bring to life every day.”
Nick Pojezny and Christoph Fark, CEOs of Heraeus Covantics
Climate Protection in Focus
As an energy-intensive company, our efforts are focused on measures to reduce greenhouse gas emissions in our manufacturing operations at our sites. The Heraeus Group reports its greenhouse gas emissions in accordance with the methodology described in the Heraeus Sustainability Report 2025 and the principles of the Greenhouse Gas Protocol.
- Scope 1 and 2 – direct emissions from our production and emissions from purchased energy. We are implementing specific measures in this area (see below).
- Scope 3 – other indirect emissions from upstream and downstream activities in the value chain.
We understand sustainability as part of the Heraeus Group’s integrated ESG agenda. This agenda is advanced across the Group; the corresponding targets and progress are reported in the Heraeus Sustainability Report.
