Put the carbon back where it came from.
Our METASTAAQ reactor recycles local agricultural CO₂ into green gas, injected into the existing heating grid. Measurable, audited, published every month.

Total CO₂ recycled by our community
The carbon warming the planet can also warm our homes.
Our emissions reach 41.6 billion tonnes per year. To absorb them by nature alone, we'd need to cover several entire planets in dense forest. The climate has run out of time.
We capture this carbon where it escapes — in agricultural methanizers — and recycle it into green gas for the existing heating grid. On 32 m², the work of 50 hectares of forest.
METASTAAQ-01.
One module. A thousand tonnes a year.
1,000 tonnes of CO₂ recycled per unit, per year.
On 32 m² of ground footprint, a single METASTAAQ unit equals about 50 hectares of mature forest in active storage — no fire risk, no decade of waiting.
Volumes aren't announced. They're published.
Every month, the exact tonnage, payments to partner farms, and third-party reports are available line by line.

No change to the gas grid. No boilers to replace at home. METASTAAQ installs next to any existing methanization unit in France.

Why planting trees isn't enough anymore.
Wondering whether carbon capture is really effective, safe, or necessary? Here are the questions Pioneers ask the most — sourced answers, no jargon.
See the full technical process →Why isn't planting more trees enough to stop excess CO₂?
Trees are essential, but global emissions reach 41.6 billion tonnes per year. Planting forests takes decades to grow and requires huge amounts of land we simply don't have. Wildfires also release stored carbon in a single summer. We need to complement nature with permanent engineering — not replace it.
Is carbon capture actually safe and proven?
Yes. Carbon capture relies on chemical processes and gas transfers that have been mastered in industry for over half a century (Sabatier reaction). Our METASTAAQ reactor recycles agricultural carbon that's already in the atmosphere — a closed loop with no fossil extraction.
Why build a community before raising funds?
Historically, green transition infrastructure was only funded by major banks or multinationals. By federating an educated Pioneer community, we put control back in citizens' hands — to co-build, scientifically validate, and directly participate in local deployment.
How do I verify my CO₂ tonnes were really captured?
Each month we publish the exact tonnage captured, payments made to partner farms, and third-party audit reports (Bureau Veritas) — line by line in our public carbon ledger. You can trace every kilo you funded back to its agricultural source.
What we captured. Line by line.
All capture transactions are published. No ghost credits, no declared tonnage. If it's not in the ledger, it didn't happen.

I had stopped believing in carbon offsets. The monthly ledger changed my mind: you see exactly where the money goes.
We're a 12-person SME. €250 per month is our real RSE policy — not communication greenwashing.
I'm an agronomy engineer. What convinced me was the public whitepaper and the complete absence of useless blockchain.
