Rubber certainly has its role to play in forest landscapes across the world, with natural rubber plantations having risen as a substantial basis of deforestation. One element that addresses deforestation concerns is the correct certification of rubber – be it natural or synthetic. International Sustainability & Carbon Certification (ISCC), a globally leading certification system, works with the objective of providing sustainability solutions for fully traceable and deforestation-free supply chains, inter alia involving the rubber industry. ISCC was one of the presenters at the Tire Technology Expo 2022 at Hannover, Germany, and Dr Jan M Henke, Director, ISCC, threw light on the nitty-gritty of certifications in the rubber industry, their clients in the tyre and rubber industry and more, in an interaction with Tyre Trends.

Can you tell us about your global sustainability scheme?
Our global sustainability and carbon certification scheme has certified companies in more than 100 countries. We certify entire supply chains from farms to plantations and forestry, and also the point of origin of waste and residues, biogenic and fossil waste. This is also covering rubber and natural rubber. Moreover, we cover biogenic waste and residues, including fossil waste, like carbon black, which is, again, used in the rubber industry. We also certify pyrolysis, where recycled mixed plastic waste can help produce synthetic rubber out of the pyrolysis oil. And we certify the entire supply chain, sustainability of raw material.

What is Meo’s role?
Meo initiated ISCC in a multi-stakeholder process a long time ago. It once was a Meo project and went on to become an operations and certification scheme. It was even recognised by the European Commission and some other authorities. It later got segregated from Meo, and ISCC is governed by the ISCC Association with more than 200 members.

So, what role does Meo play in this in case of certification?
Certification is always by independent, third-party certification bodies. ISCC is the standard development. Today’s ISCC was once a project of Meo. It then went on to become independent and operational, and was no longer a project but an individual entity running and further developing and improving the certification scheme.

The operations of the certification system, database, registration, qualification, training programme, integrity programme, the website and all the day-to-day business is done by ISCC. We are currently incorporating 45 certification bodies that are actually doing the on-site audits based on the ISCC standard.

Is ISCC recognised by the European Union?
Yes, it is being used in many sectors, like in bio energy, bio fuel, renewable transport fuels etc. In fact, ISCC is also recognised by the European Commission and by companies based on their sustainability standards and different industry initiatives.

Hence, ISCC is active on a really broad scale, covering different types of raw materials, natural rubber being one of them. We are also covering waste and residues for pyrolysis and their outputs. We then go to all the different end markets, which can be polymers, rubber, tyres, packaging, all types of plastic products, bio energy or any type of renewable fuels, aviation fuels, maritime fuels etc. This is global and is being used in more than 100 countries.

Tyre companies are talking about sustainability, but the larger part of the industry is of small stakeholders, especially in the natural rubber segment, where traceability and accountability are the main issues. How do you see this?
That’s a big challenge, especially in rubber production. At the cultivation level, there are a lot of small holders. There also exist large plantations that are easier to implement and certify. However, it’s definitely a bigger challenge with the small holders; it always depends on how well they are organised, whether there are certain structures, cooperatives or some central units.

Can you tell us about the certification of natural rubber?
The certification of natural rubber is definitely possible. Palm oil is maybe another example where the setup is quite similar sometimes. Also, with respect to the small holders, sometimes the companies are the same. Furthermore, we are very active in the palm oil sector with ISCC. We now also see a demand for natural rubber sustainability certification.

Is there a different process for getting certified in the rubber industry or is it a standard process?
It’s a standard process. It works on plantation. In fact, it works more or less the same as for palm plantations. But you certainly need to make sure that all the small holders reach a certain level, which is difficult. So starting out, bigger plantations may be easier because it’s easier for them to properly prepare for the certification audits. And then, you need to involve more farmers, step by step.

Who decides the standard process to get the certifications?
ISCC develops the standards and the requirements in the multi-stakeholder process. It then comes down to a company saying that it wants to become certified, use ISCC and also make certain claims and communications to its customers and stakeholders. They then reach out to a certification body, that is cooperating with ISCC. Following this, the certification body will do the audit on site – the third-party auditor will also make a decision on the issuance of the certificate.

Can tyre manufacturers get different certifications? For instance, one for natural rubber and another one for synthetic rubber? Or do they get one for all?
If tyre manufacturers source raw material for manufacturing from natural rubber but also synthetic rubber and everything under ISCC, then it’s one audit. Then the auditor would look into aspects of the volume of natural rubber being used that has been certified, although upstream. If one buys from certified suppliers and if the same auditors check, then aspects like the share of the certified synthetic rubber being used, the share of carbon black, etc. are taken into account. And finally, everything can be put together and a certain claim can be made.

Can tyre companies get a separate certificate for natural rubber?
Yes, they can. They can have separate certificates for natural and synthetic rubber both, or even of everything together. As for the final tyre, let’s say, if it’s 20 percent natural rubber and 20 percent synthetic rubber (40 percent of the tyre), then they can make certain sustainability claims on use of sustainable, circular materials etc.

What is the value of a certification?
It’s no deforestation – that’s key when it comes to natural rubber. When you certify, ‘no deforestation’ is the core requirement and deforestation is not allowed under ISCC. It is about additional environmental and social human rights criteria. This fits fine in this part of ISCC’s sustainability standard. And then it’s certainly about traceability in the supply chain, all the way in the end to the final tyre. And if this is established, then you can certainly make claims about the rubber or the final tyre, saying that it has been sustainably produced, based on sustainably sourced raw materials etc.

Plus, if you do this in a smart way, then you can actually cover the natural and synthetic rubber. Natural rubber and synthetic rubber are both very important parts of the final tyre. Both can be covered under ISCC.

Deforestation is a big issue, mainly in Southeast Asian and African countries. How difficult is it to keep an eye on that?
It’s not always easy to handle. Deforestation is not allowed under ISCC; there is a cut-off date of January 2008. If there was deforestation after January 2008, one cannot become certified. However, replanting or a change from palm to rubber is not considered as deforestation.

For example, if you have a palm plantation and if you cut it and plant rubber after 25 years, then that’s not deforestation. That’s just normal replanting.

Also, ISCC is certainly doing assessments, supported by remote sensing. Our core principle is no deforestation, which is very important to ISCC and its stakeholders. ISCC is not just us doing the operations in Cologne; there’s the ISCC Association for the multi-stakeholder dialogue. It has over 200 members from entire supply chains, industries, plantation companies, mineral oil, chemical companies, converters etc. We also have research organisations from different regions involved. In fact, also a number of non-governmental organisations are members of the ISCC Association.

The association meets annually and makes important strategic decisions and elects the ISCC Board. Due to the representation of the research sector and non-governmental organisations, there is quite a good balance of what people want and further development.

Can you tell us about the commercial benefits involved in having a certification?
There is a big value in it. It reduces sustainability risks for companies, helps to establish monitoring, protects the license to operate and has commercial value. For example, the OEMs ask for more sustainable products or lower greenhouse gas emissions. They all have climate neutrality commitments in place and need to start delivering step-by-step now; they need to show what are the activities that they are engaged in and how those improve sustainability in the overall supply chain. Here, ISCC certification can be used.

How do you maintain transparency in certification as a third party?
There is an annual audit. The certificate is valid for one year and then there is a re-certification. The company needs to provide evidence in every re-certification that the rules are being followed. And if they are not, a renewal of the certificates is not possible.

We certainly have quality management and training for companies and the auditors as well, who conduct on-site audits. What’s more, we have our own integrity programmes, where we send out our own auditors. These auditors work for ISCC and double-check the performance of the companies and the work of third-party auditors. Therefore, this integrity programme is key. We have the website where all the certificates are being published and the entire standard is public.

Do you help companies improve their sustainability supply chain?
No, we don’t consult. At ISCC, we are not involved in supporting the companies in order to improve. We have the standard and we conduct the training for companies. The preparation for the audit is not where ISCC is involved; it’s independent from that type of work. And the certification bodies are not allowed to consult in parallel either. ISCC is the independent standard that is used to certify that companies fulfil the sustainability requirements.

What are the other segments that you cover in the tyre industry?
It’s the entire supply chain. Petrochemical industries, tyre manufacturers etc. can all be covered. This also includes everything from plantations to the end product in the tyre industry.

Which is the easiest and the toughest one to certify?
All elements of the supply chain need to be covered.

This can sometimes be a challenge in the beginning, so as to convince your suppliers and also get certified. But, in truth, we have more than 6,000 certificates under ISCC. So there are already a lot of players that have valid certificates, and now this is starting to move into the space of rubber and tyre manufacturers.

Can you tell us about your clients in the rubber and tyre industry?
We have requests from many tyre producers right now. Some producers are certified already. Plus, we have requests for carbon black and first requests for natural rubber. We see the number of requests increasing, and we do have first certificates and first registrations from tyre producers. So we expect this to rise further as the industry needs to show compliance with their sustainability and climate neutrality commitments.

We see the entire tyre industry now targeting sustainability. So how do you find more opportunities and what’s your plan to get more client support?
ISCC started to get really further engaged in the rubber and tyre industry about a year ago; the industry has started understanding the standards, participating in ISCC trainings, joining our stakeholder events etc. Therefore, step by step, they got to know ISCC better and what it could do for them. They have now even started to get involved and do certifications, including reaching out all the way to the cultivation of natural rubber.

Are you going to focus on the Asian market?
Yes. In fact, we already have a few hundred certificates in Malaysia, Indonesia and other countries in the region. These markets are truly important. Our other key markets are North America and Europe, while we are also active in Africa and South America.

We are, eventually, trying to do more and convince people to become certified, show compliance to sustainability requirements, engage in a continuous improvement approach to become more sustainable and then allow manufacturers to really make claims.

Sumitomo Rubber Industries will rename a number of its overseas subsidiaries to carry the Dunlop brand as the company moves to unify its global tyre business and strengthen brand value across key markets.

The changes, approved by the board on 27 November, follow Sumitomo Rubber’s acquisition earlier this year of the Dunlop trademark and related rights for four-wheel tyres in Europe, North America and Oceania. The company said the rebranding supports its long-term strategy, “R.I.S.E. 2035,” which places Dunlop at the centre of its global operations. The move is still subject to approval at each subsidiary’s extraordinary shareholders’ meeting.

With the new rights in place, the firm aims to present a consistent brand message to customers around the world. It said Dunlop’s value should be reflected not only in products but also in services, user experience and corporate identity. Subsidiaries across Europe, the US, Australia, Latin America, the Middle East and Taiwan will adopt new Dunlop-branded names from January 2026, with one change planned for February.

In Europe, Falken Tyre Europe GmbH in Germany will become Dunlop Tyre Europe GmbH, while Srixon Sports Europe Ltd. in the UK will be renamed Dunlop Golf Europe Ltd. In the US, Sumitomo Rubber North America, Inc. will become Dunlop Tires North America, Inc., and in Australia, Sumitomo Rubber Australia Pty. Ltd. will take the name Dunlop Tyre Australia Pty. Ltd. Subsidiaries in Chile, Taiwan and the Middle East will also adopt the Dunlop identity.

Sumitomo Rubber said the rebranding is expected to strengthen customer recognition and help build Dunlop into a brand “chosen by customers” across regions. The company is also seeking to reinforce brand management as it expands globally, particularly in the competitive replacement tyre market.

The firm clarified that use of the Dunlop brand continues to carry certain regional exclusions, such as India and parts of Southeast Asia for four-wheel tyres, and India, Europe and Oceania for motorcycle tyres. Nevertheless, the company said it intends to apply a unified brand approach wherever possible to support long-term growth.

Bridgestone has introduced a new addition to its Potenza ultra-high-performance line: the RE-71RZ extreme summer tyre. Designed specifically for grassroots racing, this tyre succeeds the acclaimed RE-71RS model. It aims to deliver quicker lap times and sharp, responsive handling, empowering drivers to maximise their performance on the circuit. A cornerstone of its design is the incorporation of ENLITEN technology, Bridgestone's next-generation platform focused on enhancing durability and advancing sustainable product design.

The tyre's development directly targets key performance metrics. On-track testing at Japan's Tsukuba Circuit demonstrated significant improvements, with the RE-71RZ achieving lap times approximately three-quarters of a second faster than its predecessor in both dry and wet conditions. This gain is attributed to several advanced engineering features. A new high-grip rubber compound, developed using insights from motorsports and proprietary NanoPro-Tech, enhances traction at a molecular level. The tread pattern has been redesigned with a stiffer construction and a larger outside shoulder to improve grip and stability, while a strategically placed main groove on the inside edge helps suppress uneven wear for longer track life. Furthermore, Bridgestone utilised its unique ULTIMAT EYE digital modelling tool to optimise the tyre's structure, creating a more uniform contact area for superior cornering grip.

Professional drivers Masahiro Sasaki and Yuji Tachikawa provided critical feedback during development, their expertise helping to refine the tyre's track-focused characteristics. The Potenza RE-71RZ builds upon a legacy that began in 1979, crafted for enthusiasts who demand competition-ready performance that transitions from daily driving to weekend motorsports. It has been approved for competition use by the Sports Car Club of America (SCCA) and will be eligible for Solo and Time Trials events starting in 2026. The tyre will be offered in 45 sizes and is scheduled to launch in the North American market on 31 December 2025.

Sasaki said, “As its strong point, the Potenza RE-71RZ achieves a high level of performance in both grip and controllability. It delivers improved dry and wet performance for street use while also achieving faster lap times and better wear resistance on the track. This tyre delivers high performance in various situations, making it enjoyable and easy to handle for both everyday driving and track use.”

Tachikawa said, “This tyre is designed for easy handling, allowing anyone to experience precise control along with excellent grip. The tyre is focused on quick warm-up for immediate, high-grip performance as well as reliable wet grip, resulting in a well-balanced tyre suitable for various driving conditions.”

Prometeon Tyre Manufacturing is in discussions with Egypt’s Ministry of Investment and Foreign Trade over a planned US$400 million expansion, as the company moves to scale up production and strengthen its position in one of its key regional hubs.

A senior delegation from parent company China National Tire & Rubber Company met Minister Hassan Al-Khatib in Cairo to outline Prometeon’s growth plans for its Amreya factory in Alexandria. The group included chairman Wang Jian Jun, vice president Sun Deng, Prometeon Egypt chairman Omar Mehna, deputy general manager Yuan Liang, Africa–Middle East CEO Stefano Ziliani and CFO Hisham Abdel-Hadi.

During the meeting, Al-Khatib commended the pace of Prometeon’s development efforts, saying the ministry “will spare no effort to meet the company's requirements, in the context of preparing a conducive climate for investment and to protect the competition”. He also said Prometeon would receive continued backing through the China Unit at the General Authority for Investment and Free Zones to ensure the company has “all the necessary information and required data”.

Prometeon executives told the minister that the planned investment aims to increase its investments by $400 million, which is in production of 1 1 one million additional car tires and upskill the existing factory efficiency.

 Prometeon’s Alexandria complex currently produces about 5.2 million tyres annually, and the expansion would introduce new manufacturing technologies to raise output and improve capability.

As part of its proposal, the company is seeking an additional 200,000 square metres of land adjacent to its current site to support the enlarged facility. Prometeon is also exploring the establishment of a dedicated free zone to serve its export-focused operations.

For Prometeon, the investment aligns with its strategy to reinforce Egypt as a central platform for supplying markets across Africa, the Middle East and Europe. The company views the country’s manufacturing base and export access as key strengths as global demand patterns shift.

The talks signal the company’s intention to deepen its long-term commitment in Egypt, subject to final approvals and land allocation.

Yokohama Rubber Co. has opened a new passenger-car tyre plant in Hangzhou, completing the project one month ahead of schedule and marking the first major milestone under its fast-build manufacturing strategy in China.

The company held an opening ceremony recently, attended by local government officials and community representatives. Yokohama Rubber was represented by President and COO Shinji Seimiya, who praised the speed of construction and stressed the plant’s role in the group’s long-term ambitions.

In his remarks, Seimiya said he was grateful for the support that allowed the project to finish ahead of plan. He also noted that the new plant is a very important project for Yokohama Rubber's sustainable growth in the future and that every effort will be made to quickly achieve mass production and deliver high-quality, high-value-added products to the Chinese market as soon as possible.

The Hangzhou facility is the first plant built under the company’s “1-year plant” challenge, a core initiative in its medium-term strategy, Yokohama Transformation 2026. The programme aims to speed up factory construction while lowering production costs and improving efficiency. Work on the new plant began in December 2024, with operations now starting in November 2025.

The project also fulfils a request from the Hangzhou government to relocate an older plant as part of the city’s environmental plans. The new factory will have an annual capacity of 9 million tyres—about 3 million more than the site it replaces—positioning Yokohama to meet rising demand for passenger-car tyres in China. Full-scale production is expected by the second quarter of 2026.

The expansion strengthens the company’s supply of high-value tyres for China’s fast-growing new energy vehicle market, including EV-focused designs and larger rim sizes.

Alongside the rapid-build initiative, Yokohama is pushing to raise the share of premium products in its consumer tyre business by expanding sales of its ADVAN and GEOLANDAR brands, winter tyres, and 18-inch and larger tyres. The company is also rolling out regional product strategies to tailor development and sales to market-specific trends.

The opening of the Hangzhou plant underscores how Yokohama Rubber is trying to sharpen its competitive position in Asia’s largest tyre market while keeping pace with shifts in vehicle technology and local regulations.
