Our Product Stewardship Policy
Syensqo’s Product Stewardship Policy, applicable to all of its operations and businesses, strives to safeguard the health of people and the environment by promoting a comprehensive approach to chemical innovation and manufacturing.
Syensqo adheres to all applicable regulatory requirements related to product safety in every market and country we operate. We strive to go beyond compliance, setting more stringent internal standards where we believe it is necessary for the protection of people and the planet.
In particular, Syensqo intends to foster research for the development of more sustainable product solutions that benefit society and the environment, including the replacement of Substances of Very High Concern (SVHC) where feasible.
Taking action on product stewardship
Assessing SVHC in marketed products
Syensqo has developed a strategy to decrease the use of SVHC in marketed products and more broadly throughout the value chain. For this purpose, we have extended the monitoring of the SVHC of the EU REACH Candidate list and EU REACH Authorization list (annex XIV) to a worldwide scope. This has been implemented by identifying all marketed products having a concentration above 0.1% threshold of those substances on a worldwide basis.
In 2025, Syensqo's revenue from marketed products, containing more than 0,1% of substances in the candidate list, is 6,3%. Among which less than 1% is linked with persistent candidate list chemicals. In 2025, on a worldwide basis, we have identified 35 substances from the candidate list (out of 251) in our worldwide marketed products above 0.1%. Among them, 6 have the characteristics of persistent chemicals.
In addition, since 2015, we created our own reference list of substances, the Syensqo-SVHC (S-SVHC) that goes beyond the traditional EU lists (Candidate list and Authorization list) by including several lists coming from other countries (e.g. POP Stockholm Convention, China/Banned substances for manufacturing, distribution, use, importation and exportation (MEP announcement No. 23), Korea/ ISHA Harmful Substances Prohibited from Manufacturing, USA/ TSCA Annex 6, Japan/ISHL Harmful substances needing permission for manufacturing, CMR 1A/1B official classifications (EU, China, Korea). We manage these lists by identifying all marketed products having a concentration above 0.1% of those substances on a worldwide basis.
We have also established our own reference list of Substances Requiring Attention (SRA), such as substances under scrutiny by authorities, Non Governmental Organizations (NGOs), scientists and industries due to their known hazardous properties or potential effects. This allows us to anticipate risk mitigation needs and upcoming regulatory requirements. The Syensqo-SVHC and SRA lists include SVHC and SoC as defined in accordance with CSRD.
In line with CSRD requirements, our annual report 2025 mentions the quantities of SVHCs and SoC leaving our facilities as emissions and products sold.
Accounting Policy
The metrics relate to quantity in ktons of SoC and SVHC, according to the CSRD definition. Syensqo considers marketed products sold in 2025 on a global basis, mapping more than 99% in weight of those sold products. 2024 metrics have been restated taking into account most recent regulatory lists. Any SVHC or SoC present above a threshold value of 0.1% in the composition of the product is taken into account in the calculation of the metrics. Emissions refers to air emissions or water effluents from production facilities, without any threshold.
Syensqo complies with all relevant local, national and international environmental laws and regulations and takes the necessary action to reduce SoC and SVHC emissions and effluents. Emissions represent a marginal portion of the total of SoC and SVHC leaving facilities.
Those datas are covered by the Independent Auditor’s limited assurance report.

The structural reduction in the quantity of SVHC leaving facilities as emissions and in products sold is mainly due to products sold and is in line with Syensqo's Product Stewardship approach to replace SVHC where feasible.
The tables below give more insight on the SVHC and SoC by splitting them in hazard classes.
* A single substance may belong to several hazard classes. To avoid double counting, the total is the actual amount of substances and not the sum of the amount of all hazard classes.
Assessing SVHC in raw materials
We have extended our inventory process to raw materials used in production on a worldwide basis, and we identify raw materials containing a concentration of S-SVHC above 0.1%.
In 2025, on a worldwide basis, we have identified 6 persistent chemicals from the candidate list in our Raw Materials above 0.1%.
In line with CSRD requirements, our annual report 2025 mentions the quantities of SVHC and SoC procured in Raw Materials.
Accounting Policy
The metrics relate to quantity in ktons of SoC and SVHC, according to the CSRD definition. Syensqo considers raw materials purchased for production in 2025 on a global basis, mapping more than 99% in weight of those procured products. 2024 metrics have been restated taking into account most recent regulatory lists. Additionally, 2024 metrics have been restated to take into account raw materials purchased for tolling. Any SVHC or SoC present above a threshold value of 0.1% in the composition of the product is taken into account in the calculation of the metrics.

Assessing SVHC in research & innovation projects
We use our Sustainable Portfolio management tool to embed sustainability in our products during our research & innovation processes. When needed, we conduct dedicated Product Stewardship reviews, S-SVHC content checks, and assess compliance of the Raw Material or Finished Product.
For new molecules, Syensqo's dedicated team of toxicological/ ecotoxicological experts is currently developing an approach that will allow the company to achieve early identification of properties of concern.
In 2025, Syensqo launched a dedicated training program covering the type of hazards that qualify for Very High Concern and the possible means to identify them early in the R&I process. 775 persons linked with new product development completed this training in 2025.
Looking for safer alternatives for marketed products
Risk studies and Analysis of Safer Alternatives (ASA) for all marketed products containing S-SVHC above 0.1% placed on the market are regularly performed with the business and substances are replaced with safer alternatives where feasible. Syensqo also evaluates these products through its SPM tool, which assesses the chemical hazard and exposure associated with a chemical product in its use as one of the categories of signals on sustainability performance. Syensqo has also set two objectives. First, a new ASA covering newly identified listed S-SVHC should be performed within one year, and second, all current ASAs should be reviewed every three years. Syensqo achieved 100% alignment with the objectives at the end of 2025. Details of Syensqo’s Analysis of Safer Alternatives are given below, with a focus on SVHC according to the CSRD.
Those datas are covered by the Independent Auditor’s limited assurance report.

(4) Not covered by the Independent Auditor’s limited assurance report.
In 2025, 14 ASA have been completed:
- 2 led to effective replacement, through SVHC substitution, reduction below the required threshold, stopping production or through better composition knowledge.
- 5 led to an "ongoing" status meaning that an alternative has been identified and discussed with the business and/or customers for implementation.
- 7 have resulted in no available alternatives, either because no substitute is available, or too complex qualification process on customer's side.
Additional commitment to phase out fluorosurfactants
Syensqo is proud to produce a vast majority of its fluoropolymers – materials that are essential for electric vehicle batteries, hybrid engines, hydrogen applications, renewable energy installations, semiconductor manufacturing, medical devices and more – without the use of fluorosurfactants.
Guided by its sustainability roadmap, Syensqo has quadrupled its investment in research & innovation since 2019 to invent a new polymerization process that does not require the use of fluorosurfactants (non-fluorosurfactant technologies). Syensqo's goal is to phase out its use of fluorosurfactants globally.
Syensqo's success in developing non-fluorosurfactant technologies in the USA, at its West Deptford, New Jersey facility was a major step in this journey, and Syensqo is now working toward the objective of manufacturing nearly 100% of its fluoropolymers without the use of fluorosurfactants in Spinetta Marengo, Italy by the end of 2026. Today, in Spinetta Marengo, Syensqo only manufactures limited quantities of a next generation fluorosurfactant (C6O4) while the company transitions to the new non-fluorosurfactant technology. In addition, for its manufacturing in Spinetta Marengo, Syensqo applies state-of-the-art technologies that eliminate nearly 100% of fluorosurfactant emissions.
Syensqo never manufactured or sold PFOA, PFNA or PFOS. In addition, Syensqo never used PFOS or manufactured firefighting foams, which are a key source of certain PFAS in the environment. Syensqo voluntarily phased out use of PFOA and PFNA in its manufacturing processes in the USA in 2003 and 2010, respectively, and phased out use of PFOA globally in 2013.
