Environmental matters: Introduction

Shaping a resilient future

This section provides an overview of Zehnder Group’s approach to sustainability in terms of climate action, resource-efficient production, and circular products and innovation. Subsequent subchapters explore the impacts, risks, and opportunities associated with our operations and products, as well as our management approach to addressing these challenges.

Since many environmental indicators are volume-sensitive, trends should be interpreted within the context of the Group’s 2025 business performance (see Management Report). Although net sales were similar to 2023 and around 7.8% higher than in 2024, not all KPIs scale with net sales.

We always refer to CO₂e, including all relevant GHG emissions as per GHG Protocol: carbon dioxide (CO₂), methane (CH₄), nitrous oxide (N₂O), hydrofluorocarbons (HFCs), perfluorocarbons (PCFs), sulphur hexafluoride (SF₆), and nitrogen trifluoride (NF₃).
