Sustainability Metrics

Environment

PTW continuously works to reduce the environmental impacts associated with its operations. We have established the objective of reducing our market-based Scope 1 and Scope 2 greenhouse gas emissions at our Freiburg and Umkirch sites by 75% by 2030 compared to the 2023 baseline.

We already source certified renewable electricity for our production sites. Other measures include annual energy audits, the expansion of photovoltaic capacity, the gradual electrification of our company vehicle fleet, and the transition towards lower-emission and renewable heating solutions. At the Umkirch site, waste heat from production processes is already utilized for heating purposes, while QRM uses wood chips as a renewable heat source.

In parallel, we are working to better understand and reduce greenhouse gas emissions within our value chain, including Scope 3 emissions. We have also begun expanding greenhouse gas data collection and emissions analyses across our international subsidiaries to create a broader understanding of emissions within the PTW Group and to support future reduction activities.

To support lower-emission mobility options, PTW HQ offers employee mobility benefits such as the RegioKarte Job, the Deutschlandticket, and JobRad, and provides charging infrastructure for electric vehicles at its sites. Our activities are supported by an EMAS-validated environmental management system, which helps us identify relevant environmental aspects, define objectives and measures, monitor progress, and continuously improve our environmental performance.
