300ppm is the climate and sustainability investment program of ARB Investment Partners and affiliated entities. 300ppm focuses on the energy transition and sustainable food security. Our objective is to support companies in the early stages of infrastructure deployment.
300ppm was founded by Henri de Bokay together with partners including Emmanuel Birba and Ali Adoudou while working on climate change solutions at Harvard and MIT. We see decarbonisation primarily as an unprecedented technology and infrastructure development challenge, requiring a multi-disciplinary approach that cuts across traditional silos in venture capital, private equity, debt, public markets and government partnerships.
