A New Frontier for the Voluntary Carbon Market BRAZIL, January 6th, 2025 –  Today, InPlanet and Isometric announced the first-ever delivery of verified Enhanced Rock Weathering (ERW) carbon removal credits.  Carbon dioxide removal credits were developed and provided by InPlanet, verified by Isometric, delivered to Adyen, and facilitated by ClimeFi. This milestone advances the voluntary carbon market by introducing a new format of high-quality, permanent carbon removal credits for the rapidly expanding global marketplace. In natural rock weathering, carbon dioxide dissolved in water reacts with elements in rocks, forming a bicarbonate that is securely stored in oceans for over 10,000 … Read more

How do we measure Carbon Dioxide Removal?

Quantifying Carbon Dioxide Removal Through Enhanced Weathering: A manuscript Enhanced weathering (EW) is emerging as an exciting new carbon dioxide removal (CDR) technique. Enhanced weathering is scalable now and has a staggering potential to remove gigatonnes of CO2 annually. However, monitoring, reporting, and verification (MRV) of CDR with EW – how we measure its effectiveness – is widely viewed as the biggest barrier to scaling of the technique. Robust MRV is crucial to the widespread operationalization of EW. Ultimately, trust in the EW industry depends on these three letters.   To bring greater transparency to the topic, InPlanet’s research team has … Read more
