Projects
Sustainability Strategy
Period: 2022 to 2025
We provided ongoing support to the Thommen Group in the further development and implementation of its sustainability strategy. We coordinated priorities and goals with management, acted as a strategic sparring partner, and worked closely with the Head of CSR as a central point of contact. In this way, we ensured that the strategy was consistently developed and implemented.
Sustainability Report according to GRI 2021
Period: 2022 to 2025
Initially, we supported the Thommen Group in developing its first GRI-compliant sustainability report and in collecting and analyzing key environmental data on energy, CO₂, water, and waste. In the following years, we took on the preparation of additional key figures, texts, and graphics, coordinated the qualitative and quantitative data collection, and ensured compliance with relevant standards. The result was a consistent, transparent report that clearly and comprehensively communicates the Thommen Group’s sustainability strategy and performance.
GHG Accounting
Period: 2023 to 2025
We supported the Thommen Group in recording, calculating, and analyzing its greenhouse gas emissions. To this end, we calculated Scope 3 emissions, identified relevant emission sources, and created the basis for strategic goal setting within the framework of the new CO₂ Act.
Update of the Materiality Assessment
Period: 2023 to 2024
To verify the existing materiality analysis, we involved external stakeholders and obtained their feedback on the relevance of various sustainability issues. Based on this feedback, we identified the prioritized areas for action. These served as the basis for the further development of the sustainability strategy and the creation of the catalog of measures.
Targets and Measures
Period: 2023 to 2025
We supported the Thommen Group in deriving, prioritizing, and implementing specific sustainability goals and measures. Based on the materiality analysis, we created a catalog of measures for implementing the defined strategic goals and coordinated the target agreements with the federal government within the framework of the new CO₂ Act.
EcoVadis Rating
Period: 2023 to 2025
We supported the Thommen Group in preparing and submitting its EcoVadis rating, optimized the submissions, and systematically documented measures and progress. In doing so, we ensured that results from strategy, CO₂ accounting, materiality analysis, and the catalog of measures were consistently incorporated into the rating.
