At SQUAKE, we are on a mission to decarbonize the travel and logistics space, accounting for roughly 25% of the worldwide CO2. With us, companies get the support they need on their journey towards becoming CO2 neutral. In a nutshell, SQUAKE supports clients by providing them with a state-of-the-art carbon API - built by developers for developers.
