FIGHTING GLOBAL WARMING: REDUCING THE ROLLING RESISTANCE

Our goal is that each new product generation will have a lower rolling resistance compared to the previous one thereby lowering the fuel consumption of the car and the CO2 emissions.

Rolling resistance refers to the energy lost when the tire is moving as you drive. The lower the rolling resistance, the less energy is lost and less fuel needed. Better fuel efficiency affects positively the environment and the driver’s carbon footprint by reducing CO2  missions. For electric cars lower rolling resistance means also longer driving range.

In 2015, we set a goal for 2020 to reduce the rolling resistance of our product range by 7% compared to the 2013 baseline, thereby creating a decrease of 500 million kg in CO2emissions from traffic. We reached this goal clearly ahead of schedule.

We also made progress in 2018. We have reduced the rolling resistance by 8% on average since 2013.

TIRE'S MOST SIGNIFICANT ENVIRONMENTAL IMPACT: FUEL CONSUMPTION DURING DRIVING

In EU, traffic is estimated to form around 24% of the greenhouse gas emissions. The target is to reduce GHG emissions by 20% by 2020 compared with the levels of 1990. Stricter targets set by EU will apply from 2021 on.

Carbon dioxide is the most significant greenhouse gas generated by traffic. Fuel consumption during driving is the single most significant environmental impact over a tire’s service life.  

Improving the fuel economy of tires is one of our most important product development targets in the near future. We have managed to reduce the rolling resistance by improving tire constructions and compounds, among other things. We are also utilizing the latest functionalized polymers to reduce hysteresis losses and rolling resistance.

Over 90% of Nokian Tyres’ tires are in the best rolling resistance categories A, B or C. This translates to an annual decrease of over 100 million kg in CO2 emissions. To give some perspective: the most common passenger car tire label in the market is in the E category (ETRMA analysis, October 2018).

The difference is significant for a car owner – and not just environmentally. A class A summer tire that has a correct tire pressure can save up to 0,5 liters of fuel per 100 kilometers compared to the lowest performing tires.

A wise choice of tires and a careful driving style significantly reduce the CO2 emissions from driving.
