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.

TyreSafe, UK’s leading tyre safety charity, has entered a new partnership with West Yorkshire Police, reinforcing a joint commitment to road safety and reducing fatalities and serious injuries across the county. The collaboration arrives amid concerning road safety figures, with 51 deaths and 1,210 serious injuries recorded on West Yorkshire’s roads in 2025.

The two organisations will work together to highlight the essential role tyres play in road user safety. Drivers will be encouraged to perform routine checks on tyre pressure, tread depth and overall condition. The initiative also supports West Yorkshire Vision Zero, which aims to eliminate deaths and serious injuries from the county’s roads.

West Yorkshire Police becomes part of a growing network of over 260 organisations partnering with TyreSafe to promote safer motoring and enhance public understanding of tyre safety. A rising number of police forces now recognise tyre safety as a vital component of their broader road safety efforts.

As the sole point of contact between a vehicle and the road, properly maintained tyres are critical for braking, steering and grip, especially in difficult conditions. TyreSafe advises road users to check their tyres monthly and before long journeys, helping identify pressure, tread and condition issues before they become safety risks. This partnership marks another significant step in TyreSafe’s mission to reduce tyre-related incidents and improve road safety across Britain.

Stuart Lovatt, Chairman, TyreSafe, said, “We are delighted to welcome West Yorkshire Police as a TyreSafe partner. The fact that 51 people lost their lives and more than 1,200 suffered serious injuries on West Yorkshire’s roads in 2025 is a stark reminder that there is still so much work to do. Road safety requires a collective effort, and partnerships such as this are incredibly important. By combining the reach and expertise of West Yorkshire Police with TyreSafe’s specialist knowledge and campaigns, we can help ensure more road users understand the simple but crucial role their tyres play in keeping themselves and others safe.”

Inspector Claire Gray, Roads Policing Support and Proactive Intercept Team Inspector for West Yorkshire Police, said, “Every death and serious injury on our roads has a devastating impact on families, friends and communities. We are committed to working with partners to make West Yorkshire’s roads safer and to support the Vision Zero ambition. Vehicle safety is an important part of that work, and tyres are fundamental to a vehicle’s ability to stop, steer and maintain grip. We are pleased to be working with TyreSafe to help raise awareness and encourage road users to take responsibility for checking and maintaining their tyres.”

Hankook Tire has completed a significant expansion of its European manufacturing facility in Rácalmás, Hungary, marking the company's first production of truck and bus tyres on the continent. The new line, representing an investment of EUR 540 million, is scheduled to commence operations in October and has been configured to deliver more than 800,000 units annually. The first pre-production tyre from these facilities was officially unveiled at the ongoing IAA Transportation exhibition.

Previously, Hankook supplied European commercial vehicle customers exclusively from plants in Korea and China. The Hungarian line substantially reduces delivery distances, strengthening supply reliability and cutting lead times. Logistics-related carbon dioxide emissions also decline as lengthy transport routes from Asia are partially eliminated. Europe represents roughly 45 percent of Hankook's worldwide sales, making it a critical market for the tyre maker.

The Rácalmás site has received approximately EUR 856 million across three earlier expansion phases since 2007, with the third stage finishing in spring 2015. It now produces as many as 17 million tyres yearly for passenger cars, SUVs and light commercial vehicles. The fourth phase added the truck and bus tyre line and has seen around 66,000 square metres of production and support buildings constructed since 2024. More than 450 local jobs are being created. Globally, Hankook operates eight plants with capacity for up to 100 million tyres annually and employs about 20,000 people.

Designed as a highly automated facility, the new line relies on automated logistics systems, autonomous guided vehicles and real-time tracking to manage material flow and warehousing, while automated testing ensures consistent quality. Sustainability guided planning and operation through energy-efficient systems, optimised supply infrastructure and modern process controls that lower energy and water use. The plant earned ISCC PLUS certification in 2023. Production will initially centre on 22.5-inch truck and bus tyres, gradually broadening as capacity and approvals allow.

Jongho Park, President and COO, Hankook Tire Europe, said, “The expansion of our European production plant with a new line for truck and bus tyres is yet another key milestone for Hankook in Europe. The central location of the facilities in Hungary and their proximity to the core European markets is a key locational advantage. It will enable us to supply our European customers with premium commercial vehicle tyres even more reliably and quickly, and to respond to their needs with the greatest possible flexibility.”

Ho Taek Lim, Vice President and Managing Director of the plant in Rácalmás, said, “This expansion project was one of the largest industrial development projects ever undertaken at the site in Hungary. The new truck and bus tyre production facilities will transform the plant into a comprehensive production site of significantly greater complexity and with a higher level of automation.”

Continental has expanded its global ultra-high-performance tyre portfolio, covering sizes 18 inches and above, over five years and plans further growth. By late 2027, it will add over 650 new sizes across all lines for original equipment and replacement markets. This responds to demand for tyres suited to larger, heavier, more powerful and electrified vehicles, supporting profitable growth.

UHP tyres for passenger cars and light commercial vehicles now matter more to Continental and its customers. From 2020 to 2025, their share of global passenger-car tyre sales across all brands rose from 41 to 55 percent. Asia-Pacific leads at 70 percent, the Americas at 66 percent and EMEA at 43 percent. For the Continental brand, the share grew from about 49 to 62 percent.

The trend towards larger tyres links to vehicle market shifts. Cars are becoming bigger, heavier and more powerful, with SUVs increasingly common. Electric mobility is another weight driver, since batteries add considerable mass. Modern drivetrains also produce torque once associated only with high-performance sports cars. These changes demand more from tyres, which must support heavier loads while ensuring safety, efficiency and comfort.

UHP tyres combine high grip, short braking distances and precise handling with low rolling resistance and high mileage. Continental develops them mainly for wheel-and-tyre combinations of 18 inches and above, performance SUVs, premium sedans, sports cars and high-performance electric vehicles. It is expanding this range across major markets, adding over 650 sizes by the end of 2027, including secondary brands such as Semperit and Uniroyal.

This reflects growing vehicle market diversification, as manufacturers offer more variants and need tyres tailored to differing performance, efficiency and comfort requirements. UHP tyres must meet conflicting demands, balancing grip, braking, handling, rolling resistance, comfort and mileage, with rubber compounds playing a central role. Continental relies on simulations, laboratory analyses, bench tests and driving tests across varied conditions, with the High Performance Technology Center in Korbach driving manufacturing advances applied globally, where UHP tyres up to 24 inches are made.

Testing occurs at the Contidrom near Hannover, Arvidsjaur in Sweden and Uvalde in Texas, focusing on braking, handling, high-speed capability, comfort and durability. Collaboration with tuners ABT Sportsline and BRABUS, plus motorsport input through Hoosier, further advances development. The SportContact 7 exemplifies the segment, available from 18 to 24 inches and approved by Audi, BMW, BYD, Maserati, Mercedes-Benz, Polestar, Porsche, Volkswagen and Zeekr, ranking top three in 27 of 29 international tests.

Edwin Goudswaard, head of Research and Development for Continental’s Tires group sector, said, “With our expanded UHP portfolio, we are responding directly to the increasing demands of modern vehicles. This enables us to offer our customers around the world even more tailored solutions for safety, efficiency and driving dynamics. As modern tyres become larger, heavier and more powerful, tyres are becoming even more critical. They are no longer simply the vehicle’s connection to the road, but a key prerequisite for safety, efficiency and driving dynamics. The UHP segment clearly demonstrates how capable modern tyres need to be. The art lies in combining conflicting requirements at the highest level, and that is precisely what sets our tyres apart.”
