Mazda tests onboard CO2 capture during Fuji 24-Hour Race: a step toward carbon negative driving

Mazda demonstrated its Mobile Carbon Capture system at the Fuji 24-Hour Race in June 2026, successfully storing CO2 during driving. The system is still under development with no production timeline or technical specs released yet. Mazda aims to achieve carbon negative mobility by 2035, meaning vehicles that reduce CO2 the more they are driven. Endurance racing provides a demanding test environment for this early-stage technology. If Mazda can move from demonstration to practical application, onboard carbon capture could complement other emission reduction strategies. However, key details like storage capacity, cost, and packaging remain undisclosed.

Interesting to see Mazda actually testing onboard CO2 capture in a race. But without any numbers on how much CO2 they captured or the system weight, it's hard to judge if this is more than a PR stunt.

Endurance racing is a smart place to test this. Long runs with varying loads give real data. But the lack of any storage capacity or efficiency numbers makes it tough to compare against just making the car more efficient.

I wonder what the energy penalty is for running this system. If it takes significant power to capture and store CO2, it might offset the benefit. Also curious about the weight and volume of the storage unit.

Mazda's 2035 carbon negative goal is ambitious. But this is still a development program with no production timeline. The race test shows they are serious about real world validation at least.

If this ever reaches production, how would the captured CO2 be accounted for in emissions regulations? Would it count as negative emissions or just avoided tailpipe output? That matters for policy incentives.
