Project
Millennium 1

"Everest Carbon is a US-based technology company developing and operating innovative Enhanced Rock Weathering projects in India.
The company uses Wollastonite (CaSiO3), a natural mineral that weathers and sequesters atmospheric CO2 particularly fast, and their methodology is based on over 5 years of academic work and field trials of their scientific advisor, Prof. Rafael Santos, who is the leading scholar on Enhanced Rock Weathering with Wollastonite worldwide. Notably, Prof. Santos also advised on the development of the Puro Earth methodology for Enhanced Rock Weathering, which is the only certification method for Enhanced Rock Weathering to date.

Wollastonite weathers orders of magnitude faster than other materials, which puts Everest Carbon in the unique position of being able to directly measure their highly durable and irreversible carbon removals in the form of additional solid inorganic carbon content in their soil samples, allowing the company to provide definitive verification.
The Wollastonite is sourced from local mines in the districts of Ajmer in Rajasthan where each ton of Wollastonite removes 647.6kg of CO2e. Due to the close proximity of their fields, cradle-to-grave project emissions are 38.18 kg of CO2e per ton of Wollastonite, or 5.89% of gross removals.

A detailed carbon footprint description in the form of a Life Cycle Analysis is attached to this project description.
India has highly advantageous geo-climatic conditions that make Enhanced Rock Weathering particularly cost-effective there at scale as predicted for example by Beerling et al. (2020).
Our mission

Everest Carbon's mission is to scale up to a capacity of 1 billion tons of annual carbon removal before 2035 and cut costs to below $100/t before 2030, thereby providing a critical piece of technology to humanity's fight against climate change.

How it works
Enhanced Rock Weathering is the acceleration of the Earth’s natural carbon cycle. Enhanced Rock Weathering removes CO2 from the atmosphere by crushing and grinding natural alkaline silicate rocks, like Wollastonite, to fine powders and spreading them in soils. The small particle size and large contact area with the atmosphere will then increase the effective weathering rate by multiple orders of magnitude, therefore enhancing the natural weathering process.
The rock's silicate dissolves upon contact with water, releasing base cations (e.g. Ca2+) that convert atmospheric CO2 into dissolved inorganic carbon in the form of liquid bicarbonates or solid carbonate precipitation. Land surface runoff will then transport the stored carbon to the ocean where it is safely stored for tens of thousands to hundreds of thousands of years.
The methodology is possible to be replicated in many new locations and the company aims to scale quickly across India. The carbon removal purchases help them accelerate their capacity scale-up, which will bring down costs through economies of scale and learning effects."
