Climate+

We aim for climate-positive packaging by designing solutions that actively reduce emissions and remove carbon, and commit to decarbonizing our value chain in line with climate science, while enabling carbon emission savings beyond our value chain.

To achieve this, our focus within our value chain lies on:

• Accelerating decarbonization through the use of renewable, low carbon and regenerative materials across all packaging formats and the whole value chain.

• Phasing out fossil-based inputs by shifting to bio-based alternatives and renewable energy throughout the value chain.

• Enabling circularity as a complementary strategy such as keeping materials in use longer to further reduce carbon emissions and resource extraction.

• Paving the way to capturing carbon inside the SIG value chain in view of the role nature and forest can play.

Beyond our value chain we focus on:

• Helping customers and consumers reduce food loss and waste.

• Helping customers and consumers to use packaging with a significantly lower carbon footprint than conventional alternatives¹ in the segments we serve.

Through this approach, our packaging will go beyond minimizing impact. It will actively contribute to decarbonizing the food distribution system and deliver positive climate outcomes inside and outside our value chain.

1 See Our sustainability approach for details of our packaging life-cycle assessments.

Our commitments

We will drive the transition to a regenerative packaging solution that will help to remove more carbon than is emitted for production. We will achieve this in line with our 2050 Net Zero value chain commitment, with clear and ambitious SBTi-approved targets, sub-targets and collaborative actions:

• Decarbonizing our operations: As near-term targets, SIG commits to reduce absolute Scope 1 and 2 greenhouse gas emissions by 42% by 2030 from a 2020 base year and to continue annually sourcing 100% renewable electricity through 2030. And as a long-term target, SIG commits to reduce absolute Scope 1 and 2 greenhouse gas emissions by 90% by 2050 from a 2020 base year.

• Decarbonizing our value chain: SIG further commits to reduce Scope 3 greenhouse gas emissions by 51.6% per liter packed by 2030 from a 2020 base year. SIG also commits to reduce Scope 3 greenhouse gas emissions by 97% per liter packed by 2050 from a 2020 base year.

SIG is also committed to reducing climate impacts beyond our value chain by helping our customers and consumers reduce their carbon footprint.

Our approach

Measures taken and responsibilities

Decarbonizing our operations

Chief Supply Chain Officer

Eliminating fossil-based inputs will accelerate our own operational decarbonization and support our efforts to deploy a regenerative packaging solution. The following targets are driving the decarbonization of Scope 1 and 2 greenhouse gas (GHG) emissions of 42% by 2030 (from 2020).

Reduce 42% of our absolute Scope 1 emissions, by 2030 (from 2020)

Maintain 100% renewable electricity (at production plants)²

Maintain at least 25% of our global electricity consumption for our production covered by PPAs, thereof at least 10% should come from on-site solar generation

Scope 1

• We are continuing to transition our on-site fleet to electric vehicles powered by renewable electricity from our production facilities².

• Biomaterials continue to be used for printing, and we have advanced further by adopting water-based inks.

• Natural gas is being phased out through the electrification of operations and the investigation of sustainable fuel alternatives such as biogas and green hydrogen.

Scope 2

• We implemented energy-saving technologies across our factories and offices to improve efficiency and reduce consumption.

• Renewable electricity continues to be directly sourced through either on-site solar installations, Power Purchase Agreements (PPAs) or Renewable Energy Certificates (RECs) at all production plants.

• We are exploring on-site battery storage solutions to maximize the capture and use of solar energy generated at our facilities.

Operational efficiency and solar initiatives

In 2025, we accelerated our efforts to reduce our operational energy use through targeted efficiency initiatives, while continuously increasing our on- and off-site Purchase Power Agreements².

At our Linnich plant in Germany, a series of upgrades are expected to avoid 4,700MWh in natural gas and 1,600MWh in electricity use annually:

• Installation of heat recovery compressors and a heat recovery folder and sealer.

• Implementation of a weekend production plant shutdown.

• Installation of an adsorption plant for waste gas treatment.

Operating efficiency improvements in air compressor systems (a high electricity consumer) at our Thailand and Suzhou, China plants are projected to avoid energy waste of 720MWh.

Our continued rollout of on-site solar panels at our facilities in Saudi Arabia, China, India, Mexico and Austria are estimated to transition a combined 5.15MWp (Megawatt peak) capacity addition to on-site renewable energy.

2 We source 100% renewable electricity for our production and compensate for all remaining non‑renewable energy through Gold Standard CO₂ offsets.

Decarbonizing our value chain

Scope 3

The efforts needed to decarbonize our value chain will need to be varied and impactful. In developing the pathway to our 2030 and 2050 targeted Scope 3 greenhouse gas reductions per liter packed of 51.6% and 97% respectively (from 2020), we have identified key areas that will continue to drive us forward on our efforts thus far and additionally support our Nature+ commitments.

Product innovation

VP Global Research & Development and VP Global Product Marketing

Innovating our product portfolio not only advances our targets to lower emissions even further but also supports a more resource-efficient future. By rethinking how our packaging is sourced, designed, and recovered, we can drive a significant reduction in our value chain emissions.

Targeted 2030 greenhouse gas Scope 3 reductions – product innovation

Reduce 15% of Scope 3 greenhouse gas emission through SIG Product Innovation, by 2030 (from 2020)

Our product innovation efforts are closely aligned with the ambitions outlined in our Resource+ commitments which focus on maximizing renewable content, reducing raw material use and designing packaging for effective recycling.

Optimizing material use not only conserves resources but also minimizes emissions associated with extraction, processing, and transport. Furthermore, designing packaging for effective recycling helps close the loop, reducing the need for virgin materials and the emissions tied to their production.

One of the significant drivers in both decarbonization and resource minimization is the continued rollout of our SIG Terra Alu-free + Full barrier aseptic carton as part of our SIG Terra solutions.

SIG Terra portfolio

Our SIG Terra portfolio solutions lower the carbon footprint of our aseptic cartons even further, compared with standard SIG aseptic cartons, including by up to 61%¹ for our SIG Terra Alu-free + Full barrier + Forest-based polymers² solution.

By accelerating the global rollout of our SIG Terra portfolio, we estimate a cumulative reduction potential of ~139.7 ktCO₂e by 2030³ in our Scope 3 upstream emissions (materials and packaging components). In parallel, our customers can achieve an additional reduction of approximately 25% in cradle-to-SIG-gate emissions⁴, supporting their own science-based targets and decarbonization roadmaps.

Reducing climate impacts beyond our value chain⁵

Director Group Corporate Responsibility

To achieve climate-positive outcomes, we extend our efforts beyond our own value chain by supporting broader system transformation. This includes initiatives that strengthen ecosystem resilience, accelerate sector-wide decarbonization and empower informed decision-making – helping to reduce emissions across the wider food and beverage value chain.

• Together with our customer Nestlé, we partner with public institutions to support cross-sector decarbonization, such as co-funding the Chair in Sustainable Materials at the Institute of Materials School of Engineering at EPFL (École Polytechnique Fédérale de Lausanne), which researches renewable and underutilized bio-based resources as substitutes for fossil polymer feedstocks. In 2025, this collaboration yielded four scientific publications on nanocellulose films, mycelium composites, lignin-based materials, and aerogels from waste streams.

• Evidence of our lowest carbon footprint solutions are provided through publicly available, critically reviewed life-cycle assessment studies aligned with ISO 14040 standards, enabling informed and factual decision-making (see Our sustainable packaging journey)

• Through our Resource+ commitments, we enhance sector-wide end-of-life collection and recycling by embedding design-for-recycling principles and expanding recycling capacity at scale through global collaborations.

• We support nature-based solutions by investing in land restoration and improved landscape management programs that strengthen ecosystem resilience (see Nature+: Support thriving forests).

• Partnerships with NGOs, governments, and industry groups help us drive innovation in sustainability and promote climate-positive initiatives beyond our immediate footprint, such as the Food Cluster in the Climate-Health Coalition hosted by Forum for the Future (see Food+: Help transform the food system)

5 Reducing climate impacts beyond our value chain refers to climate benefits and impact reductions that other actors can achieve related to our products, services and action. Agreed methods to capture and account for positive outcomes are in development.

Outlook

Our path towards net zero

From Baseline to Transformation

Our 2020 baseline serves as the foundation for our long-term reduction pathway. Between 2020 and 2030, business growth is expected to increase emissions due to higher production volumes and expanding markets. This growth effect sets a realistic benchmark for the scale of decarbonization required to achieve our SBTi-aligned target.

Decarbonization Levers and 2030 Target

By 2025, we have already identified over 40 projects across five primary decarbonization levers with quantified reduction potential and defined financial implications. Each project was assessed for emission impact, implementation feasibility, and financial performance, ensuring that our roadmap is both scientifically robust and economically sound.

Decarbonizing our operations and value chain on our path to net zero

To meet our 2030 ambition, we will continue to operate, pilot, or deploy these projects over the next 5 years. Each lever corresponds to one of the reduction steps in our roadmap and collectively drives our transition toward science-based targets.

The cumulative effect of these actions leads to our 2030 target aligned with climate science, representing a substantial reduction in absolute emissions despite business growth. This pathway demonstrates that decarbonization and business expansion can coexist when driven by innovation, collaboration, and disciplined execution.

Decarbonizing our operations

Decarbonizing our operations will continue in earnest by phasing out fossil fuel by modernizing equipment to lower gas consumption, substituting materials that require thermal energy, and transitioning key production processes toward electricity-based solutions, and research of on-site carbon capture. Across our sites, we will continue to improve energy efficiency and source renewable electricity, while exploring battery storage to maximize solar energy use, as well as electrifying our fleet.

Suppliers, including A-materials³

As a key enabler of our reduction target, we are launching the SIG Climate+ Accelerator program to strengthen collaboration with our suppliers and accelerate measurable decarbonization across our value chain. Through this program, we will support suppliers in building the necessary capabilities, developing science-based reduction pathways, and implementing practical solutions that enable a shift from commitment to tangible progress. The program is underpinned by our extensive experience in deploying 100% renewable electricity and energy-efficiency projects, and it will be further supported by the Institut für Energie- und Umweltforschung Heidelberg gGmbH (ifeu) to bring expert know-how for the development of climate-ready execution plans. These efforts are complemented by Climate+ tendering, tailored guidance, and binding GHG reduction clauses to ensure accountability and alignment with our long-term net zero ambition.

We are also advancing procurement strategies that integrate emissions forecasts aligned with our sales goals and sourcing plans, ensuring future growth remains consistent with our decarbonization pathway. This includes a targeted shift toward sustainable, low-carbon, and recycled materials, developed in close partnership with our suppliers. Together, we are driving the development of commercially ready, lower-carbon packaging solutions that support the broader transition toward circular, climate-aligned and regenerative value chains.

Product portfolio

Our product innovation journey is entering a pivotal phase, with the scale-up of our alu-layer-free aseptic carton as a central driver of decarbonization and circularity. By phasing out the aluminum layer with our SIG Terra Alu-free + Full barrier portfolio, we will not only be reducing Scope 3 emissions but also unlock access to more efficient recycling systems – further complemented by our push to increase paper content (see Resource+). These innovations significantly lower the carbon footprint of our aseptic cartons and support our customers in meeting their own climate goals.

Eco-innovation

Alongside material innovation, we continue optimizing filling line operations to reduce energy consumption at customer sites and advancing the recyclability and reduced carbon impact of our spouted pouches and bag-in-box.

Customers and other downstream activities

Building on the continued enhancement of our packaging recyclability, we are broadening our recycling initiatives to further mitigate emissions associated with product end-of-life. This includes reinforcing industry collaborations, investing in advanced recycling technologies, and expanding programs that strengthen collection systems and improve recycling rates across key markets.

In parallel, through our Climate+ Accelerator, we are expanding our customer service offerings to actively support their energy transition. This involves assisting customers in the identification, integration, and deployment of commercially viable energy-efficiency measures and renewable electricity projects. Together, these initiatives create shared value by reducing emissions throughout the entire packaging life cycle and enabling our customers to advance toward their decarbonization and net zero objectives.

Inbound and outbound logistics

As part of the Climate+ Accelerator, we are also introducing Climate+ tendering for transport suppliers and collaborating with strategic partners to evaluate alternative fuel options that can accelerate the transition to low-carbon logistics. We are also enhancing the efficiency of our inbound and outbound transport through fleet electrification, intermodal solutions, load optimization projects, and improved route planning. These initiatives aim to reduce transport-related emissions while promoting circular supply chain practices, such as pooled pallet systems and shared logistics infrastructure, to maximize resource efficiency across our network.
