This project is a pre-purchase for carbon credits that will be generated in the future and can be retired when issued at a future date.

The biggest driver of the climate crisis is that we took the coal out of the ground and burned it. What if we could reverse that process at world-changing scale? This novel approach to carbon removal uses the best process that exists for removing carbon from the air – trees; and enhances it. The biomass is actually returned underground – reverse mining! This locks the carbon safely away for hundreds or thousands of years.

Keeping global warming to 1.5C is going to require us to launch and scale activities that remove carbon from the air and lock it away for 100s of years. Billions of tonnes of it. Getting funding to these vital projects is one of the biggest things we can do to tackle the climate crisis.

The process starts with planting of a suite of up to 13 different coppicing (able to regrow after thinning and pruning) high biomass production native Australian trees and shrubs adapted to low rainfall conditions and the different soil types. Those trees are then coppiced – thinned and pruned – to harvest the biomass. The biomass is then sequestered – compacted and then buried underground in a way that cuts off all pathways to decomposition – essentially reverse mining carbon dioxide!

One of the strengths of the EBS methodology is detailed and robust monitoring program that will take place. For those of you interested in the science part: Once live, a statistically valid analysis program will be conducted to build a robust database of CO2 captured in the biomass. Most importantly, the condition of the biomass sealed within the subterranean chambers will be monitored by a biomass decomposition early warning system. Further, physical monitoring of the actual biomass will be conducted via periodic sampling.
