InterEarth is focused on meaningful action to remove excess atmospheric CO2, now. Photosynthesis is a powerful technology to capture CO2 from the atmosphere and the backbone of our solution. We grow trees, harvest their above ground biomass and put that biomass, and its contained carbon, back underground. Safe, simple, scalable and actionable now! InterEarth is a startup with a big idea that originated with understanding the technical complexities of engineering the removal of excess, but still relatively dilute levels of, CO2 direct from the atmosphere, as well as the production and socio-economic challenges facing marginal low-rainfall farmland in Australia. It turns out that the native woodland species originally cleared to allow for farming in these areas are highly efficient at capturing atmospheric CO2, especially when routinely harvested and allowed to coppice (regrow). Combine these high production coppicing trees with dedicated subterranean biomass storage and you have a solution with Gt CO2 per year removal potential, that can start to make a difference now. There is certainly a lot of marginal low-rainfall farmland crying out for new sustainable uses in Australia and elsewhere around the world. In fact, hundreds of millions of hectares of potential production sites have been identified.
