Davida Herzl is the co-founder and CEO of Aclima, a company that builds sensor networks that monitor environmental impacts – including pollutants, carbon footprint, and greenhouse gas emissions – at a hyperlocal scale. Herzl hopes the information provided by the sensors will help people understand how the burning of fossil fuels is impacting the environment in which they live, and motivate them to seek out sustainable alternatives as consumers.
