Toyota has developed two flower variants to help offset the carbon produced by their Prius factory. One is better at absorbing nitrogen oxides, a greenhouse gas, and one that produces water vapor (also paradoxically a greenhouse gas), which is able to cool the surface of the area around the factory, requiring less energy for air conditioning. Sounds like a great concept, although I’d love to hear more about what they did to the flowers and see some calculations on how many flowers you’d actually need to make a significant impact on the carbon footprint of a car factory.
