Climate Change Mitigation

Introduction

As a supplier of vehicle parts, the reduction of emissions and energy consumption during the entire value chain are critical factors in Autoneum’s environmental impact and sustainability goals. By actively pursuing these reductions, we contribute to climate change mitigation and demonstrate our commitment to fulfilling our broader responsibility as a good corporate citizen.

Autoneum uses energy in making products through processes such as thermo forming, fiber processing, trimming, and recycling materials. This causes direct emissions from fossil fuels (Scope 1 emissions) and indirect emissions from electricity (Scope 2 emissions). For more information, see Production Processes at Autoneum below.

A significant portion of our indirect greenhouse gas (GHG) emissions are linked to purchasing materials such as aluminum, fibers, felt, and polyurethane foam, along with the transportation of these goods to and from our facilities.

Management Approach and Policies

Internal Policies

Autoneum outlines its main environmental management principles in the Autoneum Management Policy on Quality, Environment, Energy, Health and Safety. We aim to reduce our energy use and emissions, use resources efficiently throughout their life cycle, focus on sustainable actions across all business areas, and follow all relevant laws and internal guidelines. We achieve this goal by using energy-efficient technologies and practices. By doing this, we help to reduce our environmental footprint and contribute to efforts to mitigate global warming. This policy is complemented by various internal policies that address the handling of emissions, waste, water, chemicals, and hazardous substances.

We expect all our employees to act in an environmentally friendly and safe manner. This approach is guided by the 20 Principles for Good Environment, Health and Safety Behavior, which were revised in 2024 to reflect the new Autoneum values.

Governance

Operational implementation of environmental risk management—including Climate Change Mitigation—is conducted through the Corporate Responsibility Organization and the workstreams under the Corporate Responsibility Steering Committee. The Risk Council, comprising Business Group Controllers and Heads of Group Functions, performs semi‑annual reviews of risks and mitigation measures including for environmental topics such as Climate Change Mitigation. The outcomes are summarized in the Risk Report and presented to the Board of Directors and Group Executive Board.

ISO Certification

Environmental management at Autoneum is guided by the Management System for Environment, Health & Safety (MEHS), which aims to apply consistent environmental standards at all Autoneum locations worldwide and to keep improving their environmental performance. Key environmental issues that MEHS focuses on are energy and emissions. MEHS includes policies, procedures, and activities that follow international and national laws and regulations, as well as the standards of ISO 14001 for environmental management, ISO 50001 for energy management, and ISO 45001 for occupational health and safety management. We have set a target for IS0 14001 certification across our entire plant footprint (see Operational Target 2027 in the Introduction section of this Material Topic).

Each year, internal teams conduct audits at all locations to ensure they are compliant with MEHS. To help with the implementation of MEHS worldwide, we provide special training programs for Environment, Health & Safety (EHS) staff. These training sessions cover important topics, such as managing emissions and energy, as well as overall sustainability practices. Finally, our policy confirms our commitment to open and transparent communication with our employees and stakeholders on quality, environment, energy, and health and safety topics.

SBTi Targets for Scope 1, 2, and 3 Emissions

We have set ambitious and clear targets to reduce greenhouse gas emissions, which were validated by the global Science Based Targets initiative (SBTi) on January 12, 2023. These goals are aligned with the Paris Agreement’s aim to limit global warming to well below 2°C. The SBTi helps companies set science-based emission reduction targets based on the latest climate science, which in turn can help companies gain a competitive advantage in shifting to a low-carbon economy. The official wording is as follows: “Autoneum commits to reduce absolute Scope 1 and 2 GHG emissions 20% by 2027 from a 2019 base year. Autoneum also commits to reduce Scope 3 GHG emissions from purchased goods and services 20% within the same timeframe.”

Scope 3 GHG emissions come from sources that are not directly owned or controlled by Autoneum but are the result of its activities. To meet the minimum requirements set by SBTi for Scope 3 emissions, Autoneum is focusing on reducing emissions from materials and tools it buys directly, which made up to 71% of its total Scope 3 emissions in 2025¹.

Validating these GHG emission reduction targets ensures that Autoneum’s climate efforts are grounded in climate science and makes a significant step toward a sustainable future for mobility.

Improving Energy Use, Emissions at Our Plants

We are committed to improving our energy performance and ensuring the effectiveness of the Energy Management System. This involves clearly defining the system’s scope, aligning energy goals with the overall strategic direction, and ensuring performance indicators reflect our sites’ energy use. Efforts are made to regularly address risks and opportunities, provide necessary resources and training, and communicate the importance of energy management across the organization. A dedicated site representative is responsible for overseeing the system and driving improvements in energy performance. Regular risk analyses are conducted at all sites as part of MEHS. These analyses help set site-specific targets and key performance indicators (KPIs) for effective environmental management. Autoneum collects and analyzes energy data by plant, Business Group, and across the organization, providing a thorough overview of our energy consumption.

Every year, we work on becoming more energy-efficient by following the energy reduction guidelines set out by Group Operations. The potential savings from these guidelines are estimated and tracked using a continuous improvement tool. The guidelines are updated every year with new ideas that are tested and implemented through pilot projects.

We have set clear operational targets to reduce Scope 1 , 2, and 3 emissions (see Operational Target 2027 in the Introduction section of this Material Topic)^2. In terms of Scope 3, Autoneum has set targets to reduce Scope 3-Category 1 emissions, which account for more than 82% of our Scope 3 emissions. While we monitor the remaining Scope 3 emissions, we have not yet set targets on other categories³.

We have set a renewable‑energy target (see the Operational Target 2027 in the Introduction section of this Material Topic) as a core element of our path to net‑zero emissions, recognizing that increasing the share of green electricity is essential for reducing  Scope 2 emissions and aligning with our science‑based climate commitments. We advance this goal at the plant level through measures such as on‑site solar installations, renewable‑energy certificates, renewable electricity power‑purchase agreements, and the progressive rollout of ISO 50001 energy‑management systems, which help sites monitor, control, and continuously reduce energy use.

These efforts are supported by the Autoneum Management Policy on Quality, Environment, Energy, Health and Safety, which commits Autoneum to increasing the use of renewable energy and improving energy performance across all operations.

Reducing Product Weight to Lower Emissions

Autoneum is advancing the development and manufacturing of environmentally friendly and lightweight parts that offer optimum noise and heat protection. These parts make vehicles lighter, reducing our CO₂ equivalent emissions across the value chain, from using fewer raw materials (Scope 3–Category 1 emissions) to consuming less energy and fuel during the manufacturing process (Scope 1 and 2 emissions).

Our Autoneum Pure technologies (made partially or entirely of recycled materials) reduce, on average, the weight of the acoustic and soft trim package in vehicles by approximately 34%, which is equivalent to more than 7 kg for a medium-size car, versus benchmark technologies. Hence, the expected lifetime benefit in terms of emissions is around 90 kg CO₂ for a combustion engine and 30 kg CO₂ for an electric vehicle (based on European electricity mix).

Addressing Upstream (Scope 3) Emissions

We prioritize energy management with our suppliers due to the substantial emissions generated in the upstream process stages of our products. We engage with suppliers that have the highest CO₂ emissions to communicate Scope 3 emission reduction targets that align with our objective of reducing CO₂ emissions from purchased goods and services by 20% by the end of 2027.

Each quarter, we meet with selected suppliers to talk about ways to reduce carbon emissions, improve recycling rates, and launch energy-saving projects at their production sites. These efforts help Autoneum and our partners work toward achieving our emission goals. The information we ask for includes:

Key 2025 Actions, Progress, and KPIs

ISO Certification

In 2025, Autoneum successfully conducted MEHS audits at more than 87% of its sites. These audits confirmed the systems in place followed MEHS guidelines. Minor deviations were identified and actively managed by the respective plants. Noenvironmental incidents or non-compliance with environmental legislation were reported in 2025.

In 2025, 100% of Autoneum plants were certified according to the ISO 14001 standard for designing and implementing an environmental management system. For information on specialized training programs carried out for EHS functions in 2025, see the Health and Safety Material Topic.

Energy Management Measures

To improve our energy management, all Autoneum plants will progressively implement energy monitoring systems and apply for ISO 50001 certification. This certification helps to better control and reduce energy use.  In 2025, 78.6% of Autoneum plants (excluding the two acquisitions in China) were certified according to the ISO 50001 standard.

In 2025, Autoneum’s electricity use declined by 12’285 MWh compared with the previous year, which represents a decrease of 2.3% in absolute terms. Intensity increased by 6.4% (+1.5% excluding exchange rate fluctuations) due to the launch of new programs and difficulties in scaling energy consumption to adjust for changing production volumes. See the data table at this end of this chapter for other KPIs.

In 2025, Autoneum consumed 550’974 MWh of fossil fuels (523’590 MWh of natural gas, 18’804 MWh of LPG, 2’597 MWh of fuel oil, 3’239 MWh of diesel, and 2’744 MWh of coal). Fossil fuels rose by 19’559 MWh, which represents an increase of 3.7% compared to the prior year. Fossil fuels are not only used for manufacturing processes: domestic heating represents, on average, around 25% of Autoneum’s fossil fuel consumption.  In the months of January and December 2025, gas consumption at our plants in Ontario (Canada) and Indiana, Ohio, and Pennsylvania (USA) was above the average over the last five years due to severe cold weather.

In 2025, Autoneum implemented 84 energy-efficiency projects in 39 different locations across our Business Groups, which together reduced energy use by 23’868 MWh in 2025 (33’280 MWh on an annualized basis). These projects included:

Reductions in Scope 1 and 2 Emissions

In line with the reduction in fossil fuel and electricity consumption, Autoneum’s Scope 1 and 2 emissions fell by 5.3% in absolute value in 2025 compared to 2024. In local currencies, Scope 1 and 2 emissions’ intensity fell by 1.5% (+3.2% when including exchange rate fluctuations). See the data table at this end of this section for other KPIs.

The primary driver for reducing Scope 1 and 2 emissions was a decrease in the absolute value for electricity, as well as the increase in renewable energy by 4.2 percentage points. Nevertheless, the uptick in fossil fuel consumption adversely affected our overall performance regarding Scope 1 and 2 emissions. We remain committed to increasing our use of renewable energy as we continue to install solar panels at locations across our global footprint, including Setubal (Portugal) and Genk (Belgium).

In 2025, Autoneum carried out 21 projects across 14 plants to reduce fossil fuel consumption. The overall impact of these projects was a reduction of 3’029 metric tons of CO₂ equivalent for Scope 1 emissions in 2025 (4’505 metric tons of CO₂ equivalent annually). For example, discontinuing piece dyeing in Bloomsburg led to a reduction of 1’515 metric tons of CO₂ equivalent for Scope 1 emissions in 2025 (amounting to 2’118 metric tons of CO₂ equivalent on an annualized basis). The actions are tracked using Autoneum's internal tool for operational improvements, which also tracks energy, waste, and water improvements. The tool calculates one-year impacts from the implementation date, reporting only the results that are relevant to the reporting year.

Additionally, Autoneum implemented 63 projects at 25 locations to lower electricity usage in 2025, resulting in a reduction of 4’718 metric tons of CO₂ equivalent that year (or 5’970 metric tons of CO₂ equivalent annually). Pilot programs were launched to identify the electricity base load, paving the way for further reductions through a global rollout planned for 2026.

Lowering Scope 3 Emissions

In the 2025 reporting year, Autoneum achieved a 1.9% reduction in CO₂ equivalent emissions within the subcategory of direct raw‑material purchases, which is part of Scope 3–Category 1: Purchased Goods and Services. Nearly 70% of these emissions originated from our main material families: aluminum, fibers, felts, carpets, and foam reagents (polyols and isocyanates). For 2025, the primary data share–the amount of CO₂ emissions calculated with primary data from suppliers, out of overall CO₂ emissions–reached 26%.

Most of our secondary data is sourced from the LCA for Experts v2025.1 database. This version reflects CO₂  equivalent emission factors that were generally higher compared to the previous release due to a time lag in the reference year. This lag captures the post‑pandemic rebound, during which reliance on more carbon‑intensive energy sources temporarily increased, thereby negatively affecting secondary emission factors.

Against the backdrop of rising secondary data values and increased purchasing volumes, Autoneum still achieved an overall reduction in Scope 3–Category 1 emissions in 2025. This outcome was made possible through intensive collaboration and engagement with suppliers of our most critical raw‑material families, such as aluminum and fibers. By integrating primary data, we were able to counterbalance the negative impact from secondary data trends and volume growth.

Autoneum considers the shift from virgin raw materials to alternatives incorporating recycled content as a key driver of decarbonization. These materials are partially or fully derived from waste generated during industrial processes (post‑industrial) or from products after their use phase (post‑consumer). Increasing the proportion of recycled inputs lowers the carbon intensity of our raw‑material supply chain and contributes directly to reductions in upstream CO₂ equivalent emissions. Strengthening our supplier partnerships to secure reliable access to certified recycled materials will continue to be a critical enabler of our emissions‑reduction strategy. For more information on our initiatives with suppliers to reduce CO₂ equivalent emissions, see the Supply Chain Important Topic.
