WattTime is an environmental tech nonprofit that empowers all people, companies, policymakers, and countries to slash emissions and choose cleaner energy. Founded by UC Berkeley researchers and now a subsidiary of RMI, they develop data-driven tools and policies that increase environmental and social good. They invented Automated Emissions Reduction (AER), software that allows IoT devices like smart thermostats and electric vehicles as well as entire buildings to effortlessly and automatically run on cleaner energy. They popularized emissionality, a technique to achieve greater avoided emissions through better siting of new renewable energy projects. And they co-founded the global Climate TRACE coalition, which harnesses remote sensing and software intelligence to monitor human-caused GHG emissions in near real time, bringing transparency and accessibility to global emissions. During the energy transition from a fossil-fueled past to a zero-carbon future, WattTime ‘bends the curve’ of emissions reductions to realize deeper, faster benefits for people and planet.
