Mazda NewsPOSTED ON 20/11/2025Mazda begins demonstrations experiment of onboard CO₂ Capture system

HIROSHIMA, Japan - Mazda Motor Corporation today announced that it has begun demonstration experiments of Mazda Mobile Carbon Capture, Mazda's unique CO₂ capture system, in support of the theme, "The Joy of Driving Fuels a Sustainable Tomorrow," announced at the Japan Mobility Show 2025.

Mazda aims to realize mobility where “driving more leads to CO₂ reduction” by 2035. Mazda believes that if its vehicles run on carbon-neutral fuel and capture the CO₂ emitted, it will be possible to reduce the amount of CO₂ in the atmosphere in proportion to the distance traveled.

Demonstration Experiment

In the Super Taikyu Series Round 7* held on November 15 and 16, the ‘Mazda Mobile Carbon Capture’ was installed in the "MAZDA SPIRIT RACING 3 Future Concept (Car No.55)," a race vehicle, for the first time. The vehicle ran on biodiesel fuel (HVO), a carbon-neutral fuel that has been put to practical use in Europe. The device uses zeolite with a porous structure as a CO₂ adsorbent and demonstrated that it can adsorb CO₂ in exhaust gas.

Mazda will continue demonstration experiments in the Super Taikyu Series next season to increase CO₂ recovery rates. Building on insights gained, Mazda will advance its technology and equipment, contributing to the realization of a sustainable mobility society.
