The lower sales and production volumes in financial year 2024 resulted in a reduction in absolute numbers of the following key performance indicators:

Energy consumption (-28.4 percent), greenhouse gas emissions (GHG emissions) scope 1 and 2 (-32.6 percent), water withdrawal (-21.3 percent) and waste generated (-23.8 percent). Although this raised the intensity rate for the relevant environmental key performance indicators, Rieter was able to achieve all intensity targets in 2024.

• The share in renewable energy consumption increased by 5.7 percentage points to 28.6 percent. Rieter is currently developing a plan to switch consumption of purchased electricity, gas and crude oil to 100 percent renewable sources by 2030.
   
• In 2024, Rieter began to calculate and report initial scope 3 GHG emissions. Total GHG emissions (scopes 1, 2 market-based, and 3) amount to 4 246 369.5 t CO₂e. The use of products sold in the scope 3 category 11 has the largest impact on Rieter’s GHG emissions at 4 100 000 t CO₂e or 96.6 percent. In 2025, Rieter aims to start development of measures to reduce GHG emissions in this category.
   
• In 2024, the recycling rate decreased by 7.9 percentage points to 83.4 percent, due to one-time effects from the office relocation to the Campus in Winterthur (Switzerland).
   
• 2025: Rieter plans to develop new environmental targets for 2030, improve GHG emission calculation of scope 3 and work on the financial quantification of climate-related risks linked to TCFD. The company’s net zero roadmap 2040 is under development.
