Environmental Footprint of Supply Chain & Traceability
Management Approach
Upstream suppliers are essential to the Company’s business model, sustainability mission, and product quality requirements. Pollution not only harms the environment and contradicts Belimo’s ethical standards, but improving resource efficiency and reducing waste also leads to cost savings. This dual benefit motivates Belimo to minimize the environmental impact of its upstream supply chain.
Belimo holds its suppliers to the same high standards as its internal service providers, requiring full transparency to support risk assessments, including non-financial information on environmental aspects. Through supply chain due diligence, Belimo proactively identifies, prevents, and mitigates risks and impacts associated with its supply chain footprint. To ensure supply chain due diligence, Belimo has several mechanisms in place, including the Belimo Supplier Principles (Supplier Code of Conduct), as well as supplier assessment tools and audits.
Signatories of Belimo Supplier Principles
All principles of environmental responsibility for suppliers are defined in the Belimo Supply Chain Policy. Each supplier is required to sign the Belimo Supplier Principles and ensure that their own sub-suppliers comply to these standards as well.
In 2025, 98.9% (2024: 99.9%) of Belimo’s direct purchasing volume was covered by the signed Belimo Supplier Principles. All A-suppliers (i.e. those with the highest procurement volume and/or strategic importance) have signed these principles. Only suppliers with small to medium-sized purchasing volumes have yet to sign.
Environmental Assessment of Suppliers
Since 2024, Belimo has worked with EcoVadis to perform a supplier ESG risk assessment. It assesses suppliers' environmental performance in terms of energy, waste, and water resource use, eco-design in product design, life cycle analysis of products, ISO 14001 certification, use of hazardous substances, GHG emissions, and more.
The assessment follows a three-step approach:
- Holistic risk analysis with EcoVadis IQ Plus: This first phase involves mapping all suppliers based on country and industry risk factors, supplemented with 2024 spend data, to prioritize focus on A-suppliers.
- Deep risk analysis with EcoVadis Rating: Suppliers identified as high-risk and significant spend undergo a thorough ESG assessment. Particular emphasis is placed on suppliers' GHG emission reporting, decarbonization initiatives, meaningful climate targets (e.g. SBTi targets), and product carbon footprint data.
- Risk mitigation and improvement of ESG performance: Based on the ESG assessment results, suppliers receive concrete action plans to address identified risks and improve their sustainability performance.
This approach enables Belimo to monitor the environmental performance of its suppliers, identify high-risk suppliers, and collaborate with them to implement improvement measures. In step 2, the deep risk analysis, Belimo places particular emphasis on suppliers' GHG emission reporting, decarbonization efforts, meaningful climate targets (e.g. SBTi targets), and product carbon footprints. High impact suppliers are requested to set SBTi or Net Zero targets.
In 2025, a total of 93.2% (2024: 87.9%) of Belimo's direct purchasing volume (mainly A-, B-, S- (strategic) suppliers) was assessed on environmental impacts through the EcoVadis assessment.
ISO 14001 Certified Suppliers
Belimo’s direct purchasing volume with ISO 14001 certified suppliers amounted to 74.1% in 2025 (2024: 79.9%).

Supplier Audits
Alongside the EcoVadis Supplier Assessment, audits serve as a key tool for holding third parties accountable. Both selected new and existing suppliers are subject to regular process audits to ensure compliance with the Belimo Supplier Principles, including environmental requirements.
Belimo audits approximately 10% of its suppliers annually, focusing on A-, B-, and S-suppliers, categorized by procurement volumes and/or strategic importance. Each year, between one and five new suppliers are onboarded and undergo initial audits, while non-compliant suppliers are gradually phased out. Approximately 64% of the direct purchasing volume comes from suppliers with whom Belimo has partnered for over twenty years. On average, 91% of Belimo’s suppliers have sustained relationships with the Company for more than ten years.
