These deals will enable 200,000 tons of carbon removal to help Google achieve its net zero emissions goal — and help catalyze biochar production toward a scale that can help the planet mitigate climate change.
Charm’s co-production of biochar and bio-oil from its version of pyrolysis is highly efficient; for every 1 ton of biomass, a Charm pyrolyzer produces 0.2 tons of biochar and 0.5 tons of bio-oil (roughly 1 tCO₂e in total). If biomass resources were to ever be constrained, the high combined carbon yield of Charm’s biochar and bio-oil would become critical.
“With these partnerships with Varaha and Charm, we’re adding biochar to a growing toolkit of carbon removal solutions Google supports (such as enhanced rock weathering and direct air capture), and as a complement to our ongoing efforts to kickstart the carbon removal field through Frontier and Symbiosis,” Google said in a statement.
This offtake agreement with Charm and Varaha and continued commitments to carbon removal purchasing, represent a growing shift in corporate climate action to better align with the requirements to limit global temperature rise to manageable levels - the objective of Net Zero.
