Reducing our emissions and improving energy efficiency

We reduce greenhouse gas emissions in line with our science-based targets that have been validated by the Science Based Targets initiative. We calculate our tire production’s greenhouse gas (GHG) emissions from raw material purchasing to the disposal of the product in compliance with the GHG protocol. We generate part of the energy needed in our own power stations, excluding the factory in Finland. Therefore, the Finnish factory’s direct GHG emissions are lower than those of the factory in the US.

New technology benefits the society

Our zero-CO2-emissions (Scope 1 & 2) factory in Romania started tire deliveries in 2025. Benefits to society of the avoided CO2 emissions are estimated at 76,200 euros per one million tires manufactured there. The estimation is based on the following figures:

• The average weight of a passenger car tire is 10 kg
• In 2025, the CO2e emissions (Scope 1 and 2) intensity of our tire factories in Finland and US was 127 kg CO2e per ton of tires produced
• The social cost of carbon is estimated at €60 per ton of CO2e emissions.

Internal carbon pricing

Nokian Tyres introduced internal carbon pricing (ICP) for CO2 emissions reduction in 2022. The internal carbon pricing is integrated into the investment process as a shadow price, and it takes into account the impact of carbon as a factor in investment decisions regarding energy-intensive investments. Thus it can be considered to promote the transition toward carbon neutrality by driving energy efficiency and low-carbon investments and by incentivizing consideration of climate-related issues in decision making.

The price of CO2 is currently set at 50 euros per tonne, and it is typically applied to Scope 1 and 2 but can also be applied to Scope 3.

Solvents, or volatile organic compounds (VOCs), are among Nokian Tyres’ most significant air emissions. Since VOC regulations are country-specific, the calculation and reporting of VOC emissions vary by location.

In Finland, VOC emissions are calculated according to the EU’s VOC directive, and the calculation is based on the used solvents. Nokian Tyres’ ongoing air pollution target at its Finnish tire factory is to fulfill the requirements of the environmental permit. The target is mandatory, as the emissions of volatile organic compounds from the exhaust gases after the incineration plant may not exceed 20 mg C / m3 according to the Finnish factory’s environmental permit, which was renewed in 2025.

VOCs come from heavy tire assembly at the Finnish factory, and they are collected and processed at a catalytic incineration plant. However, capturing all solvent emissions from heavy tire production remains challenging because the sources cannot be completely sealed to ensure full collection and incineration. In 2025, the volume of VOC emissions was 1.5 mg C / m3 (1.5 in 2024) after the incinerator in the tire factory in Finland. Thus, the VOC-related goal was achieved.

In the US, VOC emissions are calculated in accordance with local legislation and the State-issued minor source air permit. The calculation is based on established emissions factors and the quantity of raw materials processed. There is no specific facilitywide VOC limit; rather, limits are set for individual processes within the facility. Nokian Tyres targets to stay below the permit limits. In 2024, Nokian Tyres discovered that all VOCs were not accounted for in the established emissions factors and self-reported this error to the authorities. Recalculations showed that because of this error, the air permit limit had been exceeded since 2021, and in spring 2025, the company received a penalty of $5,700 for the violation. Nokian Tyres applied for an updated minor source air permit of the US factory and received it in the fall. In 2025, VOC emissions from the US factory were 37.5 tons, remaining under the permit limit.

Particle emissions are caused by the processing of powdery chemicals in our compound mixing department. The mixing equipment is fitted with effective ventilation and dustcollection devices, and the best separation rates achieved by water cleaners exceed 99 percent. We measure particle emissions with particle concentration and differential pressure gauges. In addition, outside experts carry out regular concentration measurements.

The measured particle concentrations have complied with the permit limits at our factories. The dust that passes through the filter system mainly causes an aesthetic inconvenience and poses no harm to the environment or health.

An independent company measures the nitrogen and sulfur emissions from our own energy production plants. Our nitrogen and sulfur emissions are below the set emission limits.

According to surveys that we have commissioned, odor emissions are momentary. The mastication process for softening natural rubber causes discharges of compounds during the precipitation and dehydration phases of rubber milk that results in an unpleasant odor in the near surroundings. We use droplet separators for reducing the odors from mastication. We have also managed to lower the number of separate mastication processes, thereby reducing the related odors.

Our factories have introduced new odor control equipment that represents the best available technology (BAT). We have also managed to lower the number of separate mastication processes, thereby reducing the related odors.

Some odors are generated during the tire curing process. The quantity of the curing fumes released in the process is directly proportional to the amount of cured rubber. The concentrations of individual substances in the fumes are very small.

Our production facilities have noise limits subject to their environmental permits. We regularly track and measure noise emissions. According to the measurements, we are below the noise limits.
