After the stage-gated review of thousands of proposals, we took very deep dives into the leading submissions making use of world-experts from various institutions, business sectors and universities.

This feedback was collated by the VEC team, and we found that nothing yet sufficiently met enough of the criteria to be put to a final judgement. However… we did identify a handful entries that were clearly a cut above the rest. Entries that showed a strong chance of being able to get to a winning point as they move forward.

…these entries are the Virgin Earth Challenge finalists…


  • Biochar Solutions

    Biochar Solutions

    Biochar Solutions Inc is developing a Network of distributed carbon sequestration and soil restoration capacity by designing, producing, and selling continuous process industrial equipment to convert forest residues (carbon liabilities) into biochar and bioenergy (carbon solutions).

  • Biorecro


    Pioneers of Bio-Energy and Carbon Capture and Storage (BECCS), Biorecro’s “carbon clean-up” service delivers negative emissions by tying energy produced from burning biomass to a carbon capture and storage process.

  • Black Carbon

    Black Carbon

    The Danish integrated biochar systems company Black Carbon have developed their BC300 technology system that creates both biochar and energy from waste biomass.

  • Carbon Engineering

    Carbon Engineering

    The direct air capture company from Calgary, Carbon Engineering (CE) integrates proprietary designs with existing industrial technologies to capture CO2 directly from the air. Carbon dioxide removal. Negative emissions technologies. Direct air capture. CO2 scrubbers.

  • Carbon Sink

    Carbon Sink

    Through Infinitree LLC, a B corp. venture, Direct Air Capture technology developer Carbon Sink (also a B corp.) captures carbon dioxide from thin air and recycles it to use in greenhouses. The added CO2 allows the greenhouses to grow more food with less water and less fertilizer.

  • Climeworks


    The industriously entrepreneurial team at Climeworks GmbH, spun out of ETH Zurich, are developing a cost effective CO2 air-capture technology. In addition to negative-emissions in the long term, Climeworks are targeting the use of renewably-powered and efficiently air-captured CO2 in lucrative synthetic fuel processes in the near future. Direct air capture, carbon dioxide removal, negative-emissions. CO2 scrubbers. Removing GHGs from the atmosphere. Air to fuels. Fuel synthesis. Renewable Hydrocarbons. Renewable fuels.

  • Coaway


    Operating out of New York, COAWAY use a unique process for removing CO2 from the air and propose using existing power plant cooling towers that already move large quantities of air to create the necessary throughput for the carbon capture process. Cooling towers, direct air capture.

  • Full Circle Biochar

    Full Circle Biochar

    Integrated biochar systems pioneers - Full Circle Biochar - offer proprietary biochar products that are scalable and profitable in major agricultural markets around the globe – notably its BioCore TM and BioCharge TM offerings which are standardised and stabilised biochar products.

  • Global Thermostat

    Global Thermostat

    Global Thermostat powers its CO2 air capture technology with low-cost left over process heat emanating from power plants, cement smelters, refineries and other industrial operations. Direct air capture. CO2 scrubbers. Carbon negative solution.

  • Savory Institute

    Savory Institute

    The Savory Institute is the home of Holistic Management, a decision making framework which results in ecologically regenerative, economically viable and socially sound management of the world’s grasslands. Regenerative grazing, soil carbon, ecosystem sequestration, combating desertification, land use.

  • Smart Stones

    Smart Stones

    Based on the research of Prof. Dr. R.D. Schuiling from the Faculty of Geosciences at Utrecht University, Smart Stones promote a process for mining, milling and spreading Olivine, which naturally bonds with Carbon dioxide.
