Nature+

SIG is committed to leading the way in providing regenerative packaging solutions which contribute to halting and reversing of biodiversity loss, fostering a shift to a nature-positive economy.¹

This includes:

• forest landscape restoration and improved landscape management in hotspot areas of biodiversity loss beyond our value chain;

• assessing and mitigating biodiversity loss drivers and adverse nature impact along our supply and value chain;

• responsible sourcing of raw materials; and

• robust communication options for our customers, brands and retailers; for example, through the Forest Stewardship Council (FSC™) label use on 100% of SIG cartons².

SIG will achieve this by:

• working toward improved management of forest landscapes and restoring forest ecosystems to a state that supports resilient, self-sustaining natural processes, reducing climate change impacts and enabling thriving nature and biodiversity for future generations;

• delivering full traceability of our main raw material supply chains to understand and create knowledge regarding raw material extraction; and

• avoiding biodiversity reduction and degradation of ecosystems in our value chain through:

  • maintaining responsible sourcing based on the highest standards available for all our A-materials³;

  • preventing pollution; and

  • introducing water stewardship.

Together with our action on Climate+ and Resource+, this approach will contribute to packaging solutions designed to deliver nature-positive outcomes.

Our approach

Measures taken and responsibilities

Support thriving forests

Director Group Corporate Responsibility

Improving forest landscape management and restoration helps secure the renewable resources essential to a planet and ensures long-term material availability from nature-based systems. This approach supports a just transition by protecting ecosystem services and strengthening the resilience of communities that depend on forest landscapes.

Partner to create, protect, restore or improve management of at least 650,000 additional hectares of forest beyond what we need to make our products⁴, by 2030 (from 2020)

Work with customers to include the Forest Stewardship Council (FSC™) label on 100% of the cartons we sell, by 2030

Our approach for forests contains responsible sourcing elements and actions in projects that matter.

• We partner with WWF in the Forests Forward program, committing to a series of actions that go beyond FSC™ and connect to our Science Based Targets Network (SBTN) commitment. For further information on the Forest Forward program, see Appendix: Partnerships and memberships.

• In partnership with WWF Switzerland, we are improving the management of forest landscapes in key biodiversity hotspots, outside of the SIG value chain and in addition to the FSC™ certified forest area in our paperboard sourcing.

• As a long-standing member of FSC™ International, we actively support the development and implementation of its rigorous certification standard.

• Beyond our 100% FSC™ certified sourcing, we partner with a key Liquid Packaging Board (LPB) supplier on increasing the FSC™ group certification for small private forest owners.

• Through customer encouragement, we aim to place the FSC™ label on 100% of customer beverage cartons (96% share in 2025), showcasing packaging that is sourced without forest destruction or conversion and raising consumer awareness of the link between beverage cartons and sustainable forestry.

• Our remaining low deforestation risk is mitigated through engaging suppliers and maintaining a robust due diligence system on our LPB sourcing.

• We are continuing with our robust on-pack labeling approach which enables consumers to make choices based on accurate and substantiated information.

SIG and WWF Switzerland: A shared mission to preserve forest ecosystems

Through partnership projects with WWF, SIG is targeting improved management of 330,000 hectares of forest land in Mexico, Malaysia and Thailand, counting toward over 50% of our target to create, restore, protect or improve the management of 650,000 hectares of forest by 2030. We are working to support the other 50% through joint projects with our key paperboard suppliers.

These projects are not measured simply through reforestation but instead focus on improved management and restoration of forest landscapes (see SIG blog), protecting biodiversity, and supporting local communities in some of the world’s most ecologically significant landscapes. Together, they demonstrate how landscape-scale restoration can deliver improved climate change resilience, species protection, and sustainable livelihoods.

Mexico: Reconnecting jaguar habitats in the Central Pacific

In Mexico, the project focuses on landscape restoration for jaguar corridors in the Central Pacific Landscape. Restoration activities were performed in Nayarit and in Jalisco, including soil restoration, reforestation with 82,500 native plants in Nayarit alone, and fire prevention measures.

Community engagement was central, with 340 workshops held across 70 communities to promote holistic livestock management and coexistence with jaguars, with more than 700 producers participating in these activities. The installation of 31 electric fences helped prevent predation, avoided plant damage from livestock in the landscape corridor and provided a higher income for the farmers. Three training courses with over 80 participants were delivered to community forest fire brigades, focusing on forest fire prevention and suppression.

Wildlife monitoring using 329 camera traps confirmed jaguar presence in three key sites and more broadly across the landscape. Governance and education efforts included workshops with local “Jaguarundis”⁵ and environmental events to foster stewardship.

5 The Jaguarundis are an inter-community group involved in biological monitoring and surveillance activities, composed of 14 members from 9 communities surrounding the Marismas Nacionales Biosphere Reserve.

Malaysia: Strengthening the biodiversity and resilience of the Ulu Muda forest

In Malaysia, with the support of local partners, the project targets an improved management of the Ulu Muda Forest Complex, a vital water catchment and biodiversity hotspot. This includes restoration measures and strengthening of the community’s stewardship.

Restoration progressed this year through close engagement with the Forestry Department, site selection and development of restoration strategies. Camera trapping fieldwork within the ecological linkage connecting Ulu Muda to adjacent forest complexes revealed rich biodiversity, providing essential data to strengthen the protection and functionality of this corridor. Community engagement efforts included a carnival and a school program that highlighted the importance of the Ulu Muda forest, fostered conservation participation, explored alternative livelihoods, and supported community water-system mapping.

Thailand: Forest protection and connectivity in three important areas

Thailand’s project spans three landscapes: the Mae Ping–Omkoi Corridor, Lower Songkhram River Basin, and Thap Lan National Park.

Conservation work began in the Dawna Tessarim Landscape, with training on community engagement in designating new protected areas, and biodiversity monitoring using camera traps and management of a native tree seedling nursery. Pilot farmers adopted agroforestry training and six community forests began forest fire protection and improved forest management practices training.

In the Songkhram Basin, work began to help restore flooded forests and improve fish conservation zones, with twenty-three community groups mobilized to improve forest and fish conservation practices. Two nurseries were constructed in which local native trees will be cultivated for next year’s restoration activities, along with training on restoration techniques and seed collection.

Halt biodiversity loss

Director Group Corporate Responsibility

Halting biodiversity loss is essential for us to build a regenerative packaging system that protects nature across SIG’s entire value chain – from sourcing raw materials to end-of-life impacts. By identifying biodiversity loss drivers and prioritizing action where it matters most, such as preventing pollution, this commitment supports a just transition that safeguards ecosystems and communities reliant on them.

Assess SIG impacts and dependencies on nature and set targets for nature in line with the Science Based Targets Network (SBTN) framework, by 2027 (from 2026)

Collaborate with key A-materials³ suppliers to meet our science-based targets for nature, by 2030, representing two thirds of the A-materials procurement spend (from 2026)

• For our operations, which are predominantly situated in industrial zones, we safeguard biodiversity protection through our local EHS environmental assessments under ISO 14001 and the WWF Risk Filters on Water and Biodiversity.

• We joined the Science Based Targets Network (SBTN) in 2023 to align our approach with the Kunming-Montreal Biodiversity Framework and its goals (see Appendix: Partnerships and memberships).

• We performed an in-depth assessment of potential value chain impacts on the five nature pressures (land use and land use change, water use, soil pollution and water pollution) for our supply chain to effectively address impact reduction at scale, in line with the guidance of the SBTN.

• We are reviewing our nature-related sourcing requirements in line with identified nature pressures (see Preventing pollution and Responsible sourcing).

• To enhance consumer choice through improved information, we partner with SHINE (see Appendix: Partnerships and memberships) to advance the life-cycle assessment process, including the integration of biodiversity loss data in alignment with the Kunming-Montreal Global Biodiversity Framework.

• All efforts toward our Resource+ commitments additionally contribute to our efforts to reduce biodiversity loss primarily by delivering products with a lower environmental impact, but also by diverting used packaging from ending up in nature through collection and recycling.

Land Use Assessment

As part of SIG’s in-depth assessment of potential value chain impacts on nature from our supply chain, we used the Locate, Evaluate, Assess, Prepare (LEAP) approach to identify sourcing regions and pressures for our main Liquid Packaging Board (LPB) and aluminum. The insights from this assessment will help us to refine our approach, set targets in line with the SBTN and guide supplier engagement on potential restoration projects that directly combat biodiversity loss. Our initial findings of LPB sourcing regions and predominant tree species are presented below. The wood we use – SIG – for better

Tree species

LPB supplier data on wood supply reflects 2024 figures, as 2025 data was unavailable at the time of publication. The latest infographic and updated data will be published online at https://www.sig.biz

Prevent pollution

Preventing pollution is a key mitigation strategy addressing biodiversity loss drivers and reducing harm to human health and ecosystems across our value chain. SIG product life-cycle assessments cover all relevant environmental impacts including air and water emissions allowing us to detect hotspots along the value chain and react. By tackling major pollution sources – from raw material sourcing to water and waste management – our commitment supports a just transition that protects both nature and the communities connected to it.

Upstream

Director Group Corporate Responsibility

With a significant portion of pollution impacts occurring upstream, supplier engagement is vital to the success of commitment.

Engage with suppliers regarding pollution mitigation roadmaps (avoid, reduce, restore and regenerate) and monitor progress annually, until 2027 (from 2026)

• The certifications used for our A‑materials³, as outlined in the Nature+: Responsible sourcing target, include standards that prevent pollution.

• Supplier collaborations established under our Climate+: Decarbonizing our value chain measures drive the adoption of sustainability practices, including support for pollution reduction.

3 See Responsible culture: Our suppliers for our A-materials definition.

Downstream

Director Group Corporate Responsibility

Our efforts to prevent pollution in the downstream value chain include both internal, customer and community actions.

• Every new filling machine is designed to use less electricity and resources, including water, therefore reducing the potential output of pollutant by our customers (see Climate+: Decarbonizing our value chain).

• We support customers to reduce emissions through the SIG EcoFill Consulting program, tools and support on their product footprint and efficiency projects, including direct investments (see Climate+: Decarbonizing our value chain).

• To support the prevention of downstream pollution, such as macro- and microplastics from used packaging where household waste is not properly managed, we commit to:

  • Designing our packaging for recyclability, enabling integration into traditional recycling systems (see Resource+: Designing for recycling).

  • Enhancing end-of-life collection and recycling at scale (see Resource+: Recycling at scale).

In our operations

Chief Supply Chain Officer implemented by EHS Lead

While the majority of pollution impacts stem from other parts of our value chain, we remain committed to improving by continuously implementing robust measures across our operations. We use relatively little water, and it is not identified as a material topic for our operations, however we ensure the responsible use and discharge of water.

• We conduct regular SEDEX SMETA audits and maintain ISO 14001 certifications to uphold environmental standards (see Appendix: Certifications).

• Our responsible water use is maintained by assessing water quantity, quality, and stress risks, while striving to minimize consumption in all possible cases, including:

  • the installation of flow meters at all production plants allows monitoring of specific water usage and identifying of high-consumption areas;

  • water management systems at sites in water-stressed areas identified via the WWF Water Risk Filter;

  • monthly tracking of water consumption and withdrawal data, including fresh surface water (lakes, rivers), fresh groundwater and water discharge (returned at equal or better quality);

  • limiting water storage to fire water tanks, with minimal environmental impact unless refilling is needed; and

  • enforcement of a minimum effluent discharge quality standard, measuring chemical oxygen demand (COD) against legal limits at all sites.

• Waste reduction at SIG focuses on:

  • eliminating landfill waste through reuse, recycling, or energy recovery when other options are not feasible; and

  • ensuring responsible disposal of hazardous and electronic waste to prevent environmental harm, including from macro- and microplastics in areas where household waste is not properly managed.

• The measures taken to Decarbonize our operations, particularly those that include renewable energy generation, electrification and intensity reduction, also contribute to our efforts to prevent pollution.

Water use in our operations

A total 568,249m³ of water was supplied to SIG Group in 2025, including 327,576m³ in water-stressed areas⁶. We discharged 369,735m³ of waste water in 2025 (around 65% of the total supply), including 178,926m³ in water stressed regions.

Production waste by disposal method in 2025

6 Based on an assessment using the WWF Water Risk Filter, plants in water-stressed areas include Merced, USA; Queretaro, Mexico; Riyadh, Saudi Arabia and Suzhou, China.

Responsible sourcing

VP Global Sourcing & Procurement

Responsible sourcing plays a major role in restoring forests, halting biodiversity loss and preventing pollution, therefore mitigating negative impacts on biodiversity and achieving nature positive outcomes.

Maintain 100% certified A-materials³ (FSC™, ASI and ISCC PLUS⁷)

Sourcing of our A-materials³ from certified sources (FSC™, ASI and ISCC PLUS) contributes to all our commitments in Nature+ and further contributes to the commitments of Resource+ and Responsible culture: Communities.

• Paperboard⁸: FSC™ (Forest Stewardship Council™) certification ensures all our paperboard originates from sustainably managed forests and controlled sources⁹. The certification additionally provides guarantees that biodiversity is safeguarded, deforestation is prevented, water is used efficiently, water pollution is avoided, local communities, Indigenous peoples and workers’ rights are protected, and forest carbon storage and ecosystem services are maintained. Paperboard production additionally makes use of sawmill wood chips and saw dust residues.

• Aluminum foil: All of our aluminum foil supply chain meets Aluminium Stewardship Initiative (ASI) Performance Standards and Chain of Custody Certification, promoting responsible sourcing and production. This includes criteria for labor rights, greenhouse gas emissions, water and waste management, and a material accounting system – with links to industry waste input.

• Polymers and films¹⁰: We apply a mass balance system verified by International Sustainability & Carbon Certification (ISCC) PLUS for polymers and films, supporting the shift from fossil-based to recycled and renewable forest-based feedstocks. This certification ensures full traceability of certified materials across the supply chain and aligns with our goal to increase recycled and renewable forest-based polymers in packaging. Available for all our aseptic cartons, our renewable forest-based polymers solution is linked to tall oil, a wood component and residue in papermaking, while our circular polymer solutions are linked to post-consumer recycled plastics.

Customers are encouraged to include the Aluminium Stewardship Initiative (ASI) Responsible Aluminium Sourcing logo on their packaging designs, enhancing information and allowing customers to choose responsibly sourced materials.

3 See Responsible culture: Our suppliers for our A-materials definition.

7 This target only includes ISCC PLUS certification of polymers linked to forest-based renewable or recycled polymers through mass balancing, as there are currently no certification schemes available, or expected in the near term, for other polymers that meet our high sustainability standards.

8 Our cartons use paper-based liquid packaging board, referred to throughout as “paperboard”.

9 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.

10 SIG currently uses ISCC PLUS certified bio circular polymers which are mass balanced and where it is ensured that a corresponding amount of fossil feedstock is replaced with the wood component tall oil in the polymer production.

2026 to 2030 targets

See Appendix: Key performance indicators for related key performance indicators.

Outlook

In the years ahead, SIG will accelerate Nature+ by regenerating nature – working both within our value chain and beyond it.

Together with our suppliers and the WWF, we will advance thriving forest projects that contribute to our target of creating, restoring, or improving the management of 650,000 hectares of forest landscapes by 2030. These efforts will enhance biodiversity, strengthen ecosystem services, and secure renewable resources essential to our regenerative packaging approach.

In parallel, we will further align our efforts and targets with the Kunming-Montreal Biodiversity Framework, in line with the requirements set by Science Based Targets Network (SBTN). At the same time, we will further expand traceability of key raw materials and reinforce responsible sourcing to address the main drivers of nature loss.

Building on these efforts, we will deepen our work on pollution prevention and water stewardship with suppliers and at our own sites.

Through these actions – and in close collaboration with WWF and other partners – SIG will help restore ecosystems, enable resilient communities, and advance a regenerative, nature-positive economy.
