Michelin’s CO2 emissions-reduction targets have been validated by SBTi, a leading independent collaborative organisation in this field.

The success of the COP21 Paris Climate Agreement depends not only on the commitment of member States but also on the involvement of civil society and the private sector in collectively reducing greenhouse gas (GHG) emissions.

That’s why Michelin Group voluntarily submitted its CO2 emissions reduction targets to the SBTi for approval.

Michelin commits to reduce absolute scope 1 and 2 GHG emissions by +38% by 2030 from a 2010 base year. Michelin commits to reduce absolute scope 3 GHG emissions from fuel- and energy-related activities; upstream and downstream transportation and distribution; and end-of-life treatment of sold products by +15% by 2030 from a 2018 base year. Michelin also commits that +70% of its suppliers by emissions covering purchased goods and services will have science-based targets by 2024.

Scope 1 emissions are generated by sources owned or controlled by the Company, while Scope 2 emissions result from the generation of energy that is purchased and consumed by the Company. Scope 3 covers emissions resulting from the company's business but generated by sources not owned or controlled by the Company.

Obtaining approval from SBTi represents a first step toward carbon neutrality by paving the way for net-zero Scope 1 and 2 emissions at all Michelin sites by 2050.

The SBTi method is also an opportunity for Michelin to strengthen its commitment to its suppliers, in order to increase their societal responsibility through targeted action on CO2 emissions reduction in the production of raw materials.

“Gaining SBTi’s approval of our CO2 reduction targets is additional proof of the pertinence of our environmental strategy. Michelin Group has great ambitions, fully in line with its strategy, and a very long-term vision with regard to the fight against global warming. I firmly believe that for all of our business lines, the current crisis is an opportunity to step up our activities, products and initiatives aimed at protecting the environment,” said Florent Menegaux, Michelin Group CEO

Zeon Corporation has announced the development of Nipol BR1300, a novel hydrophilic styrene butadiene rubber (SBR) for winter tyres. Synthesised with a polybutadiene rubber base, the material delivers unprecedented hydrophilicity for tyre applications. Commercial production began in May 2025 at Zeon’s Tokuyama plant in Yamaguchi Prefecture.

As part of its strategic portfolio optimization, Zeon plans to phase out low-profitability products like ESBR-1 and NBR latex by 2026. However, it will continue manufacturing high-margin products, including ESBR-2, nitrile butadiene rubber and solution SBR. This shift underscores Zeon’s focus on advanced, value-driven rubber solutions.

Covestro India has entered into a strategic collaboration with CSIR-National Chemical Laboratory (NCL) through an innovative CSR initiative focused on developing sustainable upcycling technologies for polyurethane waste. This partnership aims to overcome existing recycling limitations by transforming discarded polyurethane materials into valuable chemical feedstocks, potentially revolutionising the material's circular economy.

This collaboration underscores both organisations' commitment to environmental innovation, leveraging NCL's advanced research infrastructure and Covestro's market leadership to address critical gaps in plastic circularity. Current polyurethane recycling methods, predominantly mechanical with some emerging chemical processes, face substantial challenges including material degradation, high energy consumption and hazardous byproduct generation. The project seeks to develop commercially viable chemical recycling solutions that maintain material integrity while minimising environmental impact.

Polyurethanes, widely used in furniture, automotive parts and insulation, present unique recycling difficulties due to their complex molecular structure. Most end up in landfills after use, creating significant sustainability challenges. By combining Covestro's industrial expertise with NCL's seven decades of chemical research excellence, the partnership aims to create breakthrough upcycling technologies.

Avinash Bagdi, Director & Head of Sales & MD Solutions India & Projects – Tailored Urethanes, said, "This partnership strengthens our commitment to finding innovative solutions for polyurethane waste and directly supports Covestro's vision of becoming fully circular. By developing effective methods to upcycle polyurethanes, we're taking concrete steps towards creating a more sustainable future in line with our corporate vision of driving the transition to a circular economy."

Dr Ashish Lele, Director of NCL, said, "CSIR-National Chemical Laboratory is excited to partner with Covestro (India) in this groundbreaking initiative to develop novel chemical upcycling methods for polyurethane waste. The conventional and electrochemical strategies we're developing address the critical limitations of current recycling technologies and align perfectly with our shared vision of a circular economy. This collaboration represents a significant step towards sustainable plastic management in India and globally, with potential to transform polyurethane waste into valuable chemical resources."

Zeon Corporation has begun building a pilot facility at its Tokuyama Plant in Shunan City, Yamaguchi Prefecture, to test a new method for efficiently producing butadiene from plant-derived ethanol. The demonstration plant, expected to start operations in 2026, will supply butadiene for manufacturing trial batches of polybutadiene rubber, bringing the company closer to commercialising this sustainable production process.

This project is a key part of a joint initiative between Zeon and The Yokohama Rubber Co., Ltd. to develop eco-friendly methods for producing butadiene and isoprene from renewable sources, with full-scale adoption targeted for the 2030s. Under the collaboration, Zeon will produce butadiene rubber at the new facility, while Yokohama Rubber will use the material to create experimental tyres and conduct performance testing. The data collected will help refine the technology ahead of larger-scale trials. The companies aim to finalise the production process by 2030 using an expanded pilot plant, with plans for industrial-scale commercialisation by 2034.

A ceremonial groundbreaking event took place on 10 July 2025, with 33 attendees, including local government officials from Yamaguchi Prefecture and Shunan City, construction partners and Zeon executives such as Chairman Kimiaki Tanaka and Tokuyama Plant Manager Akira Honma. The gathering included traditional safety prayers for the construction phase, marking the official start of this sustainability-focused industrial project.

Continental is increasing its use of renewable and recycled materials in tyre production, aiming to exceed 40 percent by 2030 while maintaining high safety and performance standards. In 2024, these materials accounted for 26 percent of tyre composition, with a projected 2-3 percent increase in 2025. Key to this shift are carbon black and silica – essential fillers that enhance durability, grip and braking performance.

Silica, a critical component for optimising grip and minimising rolling resistance, is traditionally derived from quartz sand. However, Continental now obtains silica from rice husks, an agricultural by-product of risotto rice production. This innovative approach not only repurposes waste but also requires less energy than conventional methods. Partnering with manufacturers like Solvay in Italy, Continental integrates rice husk-derived silica across its entire tyre portfolio. Silica has been a game-changer in tyre technology for decades, significantly improving safety and energy efficiency. Its use in tread compounds has contributed to a nearly 50 percent reduction in braking distances while also lowering rolling resistance, thereby reducing fuel consumption and CO₂ emissions.

Carbon black, another vital material making up to 20 percent of a passenger car tyre's weight, is being sourced through sustainable alternatives. Continental employs three innovative methods: bio-based carbon black from tall oil (a paper industry by-product), recycled carbon black from pyrolysis oil derived from end-of-life tyres and a direct recovery process that extracts carbon black from used tyres via pyrolysis. The company collaborates with suppliers like Orion Engineered Carbons and Tokai Carbon, utilising different carbon black variants tailored to specific tyre components, such as sidewalls and treads. Through the mass balance approach, Continental substitutes fossil-based raw materials with bio-based or recycled alternatives without altering existing production processes.

Additionally, Continental has partnered with Pyrum Innovations to advance tyre recycling through pyrolysis, a process that recovers carbon black from end-of-life tyres for reuse. While currently applied in forklift tyres, efforts are underway to adapt this recycled carbon black for broader tyre applications, ensuring compliance with performance and safety standards. These initiatives underscore Continental’s dedication to sustainable innovation, demonstrating how eco-friendly materials can enhance both tyre performance and environmental responsibility across the value chain.

Jorge Almeida, head of Sustainability at Continental Tire, said, “Innovation and sustainability go hand in hand at Continental. Using silica from the ashes of rice husks in our tyres shows that we are breaking completely new ground – without compromising on safety, quality or performance.”
