A Mazda3 Race car equipped with the brand-new “Mazda Mobile Carbon Capture” technology participated in the 7th round of the 2025 Super Taikyu race series on the Fuji International Speedway in Oyama, Japan, last weekend.
During the four-hour race, Mazda’s new carbon capture device demonstrated it could adsorb CO2 in exhaust gas under challenging motorsports conditions for the first time. Mazda will continue to test the technology in the Super Taikyu race series next year, aiming to further enhance the CO2 recovery rate.
A concept model of a carbon capture device was presented at the Japan Mobility show on 29 October 2025. The “Mazda Mobile Carbon Capture Technology” prototype tested uses a Zeolite porous structure to adsorb CO₂ from exhaust gases and stores it in a tank. The captured CO2 could be used to manufacture high-performance carbon materials or to enrich greenhouse air with CO2 to boost crop growth. To further reduce CO2 emissions, the car was fueled with HVO 100 carbon-neutral diesel fuel.
While proceeding to develop electrified vehicles of every degree including mild hybrids, full hybrids, plug-in hybrids and battery electric vehicles, Mazda continues to further reduce the CO2 emissions of its internal combustion engine powered vehicles by enhancing engine efficiency, by supporting the development and introduction of carbon-neutral fuels, and by collecting CO2 from exhaust gases.
Mazda is committed to achieving carbon neutrality globally by 2050 and to meeting the 2030 and 2035 EU interim targets with its Multi-Solution Approach. The Japanese car manufacturer believes that a multitude of technical solutions is the most effective way to reduce CO2 emissions of its vehicles.
