Climate change can feel overwhelming, especially when we hear how much carbon dioxide (CO₂) humanity releases every year. Cutting emissions is essential—but scientists agree it won’t be enough on its own. We also need to remove carbon already in the atmosphere. That’s where the Carbon XPRIZE comes in.
At Climatewise Living, we believe understanding real-world solutions helps people move from climate anxiety to climate action. Here’s a simple, easy-to-read breakdown of what the Carbon XPRIZE is, why it matters, and what it has achieved.
What Is the Carbon XPRIZE?
The Carbon XPRIZE was the largest climate incentive competition in history. Launched on Earth Day 2021, the four-year, $100 million competition challenged teams around the world to prove they could remove carbon dioxide from the air or oceans at meaningful scale—and do it affordably.
The prize was sponsored by the Musk Foundation and run by XPRIZE, an organization known for using competitions to accelerate breakthrough technologies.
The goal was ambitious but clear:
-
Demonstrate real-world removal of at least 1,000 tons of CO₂
-
Show a clear path to megaton and gigaton-scale removal
-
Prove the cost could eventually fall below $100 per ton
-
Ensure solutions are durable, sustainable, and scientifically verified
Why Carbon Removal Matters
Carbon dioxide accounts for more than two-thirds of global greenhouse gas emissions. Even if the world rapidly cuts emissions, CO₂ already in the atmosphere will continue warming the planet.
Scientists estimate we will need to remove 6–10 gigatonnes of CO₂ every year by 2050 to avoid the worst climate impacts, including:
-
Rising sea levels
-
Longer and harsher droughts
-
More frequent extreme weather
Without scalable carbon removal, staying below 1.5°C of warming becomes extremely unlikely.
What Made the Carbon XPRIZE Different
This wasn’t a paper exercise or a lab-only challenge. Teams had to prove their ideas worked in the real world.
XPRIZE worked with independent scientists and validators to examine:
-
Energy use
-
Land and water impacts
-
Life-cycle emissions
-
Long-term carbon storage (durability)
Only solutions that showed real climate value—not accounting tricks—advanced.
More than 1,300 teams from 88 countries entered, creating an entirely new global pipeline of carbon removal innovation.
The Types of Solutions Tested
One of the most exciting outcomes of the Carbon XPRIZE is how many different approaches were validated. These included:
-
Direct air capture (machines that pull CO₂ from the air)
-
Ocean alkalinity enhancement (using chemistry to store CO₂ in seawater)
-
Enhanced rock weathering (spreading crushed rock to lock away carbon)
-
Biomass-based storage (turning plant waste into stable carbon forms)
This diversity matters. There is no single “silver bullet” for climate change—successful carbon removal will likely require many solutions working together.
Milestone Winners: Proof That Scaling Is Possible
Before the final awards, XPRIZE issued $1 million Milestone Awards to teams that showed strong progress. These included:
-
Air-based solutions like Calcite, Carbyon, and Heirloom & Carbfix
-
Land-based solutions such as the Bioeconomy Institute Carbon Removal Team and Global Algae Innovations
-
Ocean-based approaches including Captura and Marine Permaculture SeaForestation
-
Rock-based storage led by Carbin Minerals
These milestones helped teams move from promising ideas toward commercial reality.
The Grand Prize Winner (and Runners-Up)
The final awards were announced in April 2025, marking a major moment for the carbon removal industry.
Grand Prize Winner
Mati Carbon won for its use of enhanced rock weathering. By spreading crushed basalt on smallholder farms in India, Mati Carbon locks CO₂ into stable forms for thousands of years—while also improving soil health and crop yields.
First Runner-Up
NetZero uses agricultural waste to produce biochar, permanently storing carbon while generating clean energy.
Second Runner-Up
Vaulted Deep permanently stores CO₂-rich organic waste deep underground.
Third Runner-Up
UNDO Carbon also uses enhanced rock weathering to remove CO₂ at scale.
XFACTOR Awards
Special recognition went to Planetary for ocean-based solutions and Project Hajar for air-based removal.
Why This Matters for Everyday People
The Carbon XPRIZE didn’t just hand out awards—it helped create a real carbon removal industry. Many finalist teams have since secured:
-
Commercial contracts
-
Partnerships
-
Venture investment
This builds trust in carbon removal at a time when many people are rightly skeptical of offsets and climate claims.
For families, preppers, and climate-conscious consumers, this matters because:
-
Climate solutions are moving from theory to reality
-
Costs are falling through real-world deployment
-
High-quality carbon removal is becoming measurable and verifiable
The Big Takeaway
The Carbon XPRIZE shows that climate progress is possible when innovation, science, and accountability come together. Removing carbon at scale is hard—but it’s no longer hypothetical.
At Climatewise Living, we see this as a sign of cautious optimism. The climate challenge is enormous, but human creativity is rising to meet it—one validated solution at a time.
