Certification journey

We track the progress of a carbon removal project through our certification framework. This roadmap moves from a preliminary assessment of eligibility toward full certification under the Puro Standard.

The facility has successfully completed the preliminary assessment conducted by the Puro team, meeting the minimum criteria for listing as a future supplier on Puro.earth.

The facility has passed the third-party facility audit, verifying compliance with the methodology, as well as output audit, verifying the net volume of removed carbon. The facility has been issued CORCs and continues its removal operations, as well as monitoring and reporting to Puro.earth.

Development status

We monitor a facility’s maturity as it moves toward industrial-scale operations. This status identifies whether a project is in development, under construction, or actively removing carbon from the atmosphere.

The feasibility study is ongoing. The Supplier is still collecting data to prove the concept.

The front-end engineering and design are ready and methodology compliant. There is a clear plan to monitor and measure. The LCA is up to the needed quality level or subject to small improvements. The technology has been used before. There are commercial agreements with the relevant business partners of the facility.

The facility is fully funded and is being implemented. Relevant infrastructure is being built.

The facility is operating as a carbon removal facility.

More about Enhanced Rock Weathering – Smallholder farmers in India

Varaha’s Enhanced Rock Weathering (ERW) project applies finely crushed basalt rock powder across agricultural lands in central India. Started in H1 2024, this initiative leverages basalt’s natural ability to capture atmospheric CO₂ while improving soil health. The basalt, a byproduct of mineral sand production for the construction industry, is sourced locally to minimise transportation-related emissions. It is applied to tropical, mildly acidic black cotton soils, which provide favourable conditions for rapid weathering.

Varaha’s advanced monitoring, reporting, and verification (MRV) system ensures scientific rigor and transparency, tracking each ton of basalt from quarry to field, performing high-density soil sampling, and monitoring changes in soil properties to confirm carbon removal and soil health benefits.

Varaha’s Enhanced Rock Weathering (ERW) project delivers multiple positive impacts. By applying basalt rock powder to acidic agricultural soils, the project has significantly improved crop yields and reduced farmers’ dependency on chemical fertilisers, enhancing soil health and resilience to climatic variability. The project has also created rural employment opportunities.
