Certifications

Certified or verified to highest recognized standards

We use independent third-party certifications to highest recognized external standards to demonstrate our robust management of sustainability and ESG topics and support continuous improvement in line with best practice. These certifications include:

• ASI (Aluminium Stewardship Initiative): Our aseptic carton business is ASI Performance Standard Certified, all associated SIG production plants are ASI Chain of Custody Certified, and all aluminum foil for our aseptic cartons is purchased from ASI Certified suppliers.

• FSC™ (Forest Stewardship Council™): Chain of Custody certification is in place at all our aseptic and chilled carton production plants, and related sales offices (FSC™ license code FSC™ C020428). All the paperboard for our cartons is purchased with FSC™ Mix certification¹.

• GFSI (Global Food Safety Initiative) recognized standards: Our packaging production plants maintain top level certification with GFSI-recognized standards (except for Voronezh, Russia, due to limitations in respect of data access, and Hsinchu City, Taiwan). These standards include Brand Reputation Compliance Global Standards (BRCGS) packaging standard, Safe Quality Food (SQF) and Food Safety System Certification (FSSC 22000). Our Hsinchu City, Taiwan plant is currently certified to ISO 22000:2018 and working towards certification to a GFSI-recognized standard.

• ISCC (International Sustainability and Carbon Certification) Plus: Certification to handle ISCC Plus certified renewable forest-based (linked to tall oil) and recycled polymers is in place at all our aseptic carton sleeve production plants (except Ahmedabad, India) and at the spout production of allCap in Switzerland.

• ISO 14001: ISO 14001 is a structured framework for organizations to manage and improve their environmental performance, and SIG maintains global certification. The standard supports our commitment to minimizing environmental impact through systematic planning, implementation, and continuous improvement. Key objectives include ensuring compliance with legal and regulatory requirements, reducing resource consumption and waste, and integrating sustainability into core business strategies. Through its core components – such as environmental policy, performance evaluation, and corrective actions – ISO 14001 enables SIG to enhance operational efficiency, strengthen stakeholder trust, and drive measurable progress toward our environmental goals.

• ISO 14040 and ISO 14044: Independent experts use these standards to carry out ISO-conformant life-cycle assessments of our packaging solutions that are critically reviewed by an independent panel for additional verification. In addition to greenhouse gas emissions, these assessments take a more comprehensive view – capturing a wide range of environmental impacts such as resource use, pollution, and effects on ecosystems and human health.

• ISO 27001: Certification to ISO 27001 for information security management is maintained in China, Germany, and Romania, scoping the provision of Information Communication Technology Infrastructure, related applications, data centers, and production operations.

• ISO 45001: ISO 45001 certification requires the integration of health and safety into strategic planning, leadership, and operational processes, with a strong emphasis on worker participation, risk assessment, legal compliance, and continuous improvement. By maintaining this certification for all plants, SIG proactively improves employee safety, reduces workplace risks, and fosters a culture of well-being and engagement, while strengthening organizational resilience and reputation.

• ISO 50001: Certification to ISO 50001 for energy management is maintained at our three aseptic carton production plants in Europe and at our bag-in-box and spouted pouch plant in Eisfeld (Germany).

• ISO 9001: Certification to ISO 9001 for quality management is in place for our aseptic carton production globally, and for some bag-in-box and spouted pouch production plants.

• LEED: Our Middle East and Africa headquarters and Tech Center in Dubai have achieved Platinum LEED certification for sustainable buildings, as has our Tech Center in China. Our second plant in Suzhou (China) and our new plant in Querétaro (Mexico) have achieved Gold.

• SEDEX Members Ethical Trade Audit (SMETA): SIG undergoes regular SEDEX SMETA audits to verify and enhance sustainable and responsible practices across its operations and supply chain, encouraging suppliers to join us in applying the same framework. Every two years, we conduct SMETA audits at all production sites², with SEDEX Self-Assessment Questionnaires on human rights risks completed at all other non-production sites with the same regularity. The audits combine policy reviews, site inspections, risk and impact assessments and confidential worker interviews to assess:

1 Our cartons use paper-based liquid packaging board, referred to throughout as “paperboard”. SIG uses FSC™ Mix material that allows the mixing of FSC™ certified wood with FSC™ controlled wood and ensures that an equivalent amount of FSC™ certified wood is procured at the beginning of the value chain.

2 Excludes our production plant in Voronezh, Russia, due to limitations in respect of data access.
