I’d say that this is about as far “out of the box” that you could go as a car manufacturer.
Toyota has genetically engineered flowers to eat up the emissions that their factories produce. It seems like a perfect solution (as long as the flowers don’t start eating people).
"The sage derivative’s leaves have unique characteristics that absorb harmful gases, while the gardenia’s leaves create water vapour in the air, reducing the surface temperature of the factory surrounds and, therefore, reducing the energy needed for cooling, in turn producing less carbon dioxide (CO2)."
