Mazda’s global chief financial officer, Jeff Guyton, has taken aim at the world’s fixation on electric cars, stating that the globe is missing the picture on how to cut carbon emissions.

Mr Guyton confirmed Mazda is developing biofuels from algae, a process that distils oils from grown organisms that can be used in any existing car. “This fuel could go in any car; it doesn’t have to go in a special Mazda engine,” he said. “It’s a powerful way to address the installed vehicle base.” Mazda is also developing a carbon capture system that collects carbon dioxide from a vehicle’s exhaust. “The exhaust from an engine is CO2-rich, it’s a target-rich environment to grab CO2 from,” he explained.

Mr Guyton said Mazda will test the technology later this year during an endurance race, though Guyton admitted there’s “no timeline yet” for production.
