When a vehicle is in motion, a variety of resistance factors are working against it, including air resistance and tire rolling resistance, all of which increase fuel consumption. Minimizing these resistance factors enables the vehicle to use less energy, which leads to improved fuel efficiency.
For the target of a 25 percent reduction in tire rolling resistance by 2020 (from a 2005 baseline), we achieved a 21 percent reduction (equals to contribution to approximately 13.4 million tonnes reduction CO2*1) in 2018. Improving rolling resistance and maintaining safety at the same time is a difficult task that requires innovative technologies. Bridgestone has developed NanoPro-Tech™*2 technology and promotes sales of fuel-efficient tires utilizing this technology around the world, helping to reduce CO2 emitted at the usage stage. Bridgestone’s CO2 emissions are verified by a third-party institution promoting transparency of information.
