Kepler Carbon develops, certifies and delivers measurable CO₂ removal made from Chinese crop residues, so businesses can move beyond net zero.
Carbon,removed.
(02) About
We take carbon 
out of the air and lock it 
into the ground, with proof 
that anyone can check. Climate action means more than cutting emissions.
Rebalancing the atmosphere
Kepler Carbon brings together biochar, mineralization and ecological restoration pathways. We deliver end-to-end services, from project development and digital monitoring to international certification and the delivery of credits to buyers.
Why biochar
When crop straw, stalks and husks are heated without oxygen, the carbon they captured from the air while growing is turned into a stable, porous solid. Spread on farmland, that carbon stays in the soil instead of returning to the atmosphere as the residue decays.
Europe and China
With roots in Europe and operations in China, we work alongside governments, industrial parks, corporate buyers and international registries, so that every tonne removed is real, verifiable and worthy of trust.
(03) From straw to credit
Straw, not smoke
Every year, Chinese farms leave behind vast amounts of rice and wheat straw. Burned or left to rot, its carbon returns to the air. We collect it from partner farms in Anhui instead.
Heat without oxygen
At a partner plant the straw is heated in the absence of oxygen. Instead of burning, it becomes biochar, a stable carbon skeleton that keeps much of the carbon the plant absorbed.
Locked into the field
Each batch is tested in an accredited lab, then spread into farmland with GPS-logged placement. It holds water and nutrients for the farmer, while its carbon stays out of the air for centuries.
Verified, then sold
An independent verifier reviews the full record before the registry issues serialized credits. Buyers retire them with a certificate that names the project and the batch.
(04) The market
Buyers now pay for delivered removal.
Biochar is the carbon removal method that buyers are actually receiving today. Corporate demand keeps rising, and supply that can be traced batch by batch is still scarce.
Biochar removal credits contracted by corporate buyers, including future deliveries.

(05) What we do
One material. Six values.
Built around biochar, Kepler connects carbon credits, green agriculture, soil restoration and industry support into one value chain.
Credit generation and trading
We develop biochar removal projects and issue and trade credits on Carbonfuture, Isometric and Puro.earth, so every tonne removed in Chinese fields becomes an asset recognised worldwide.
Carbon credits 02Biochar fertilizer R&D
We blend biochar with organic fertilizer into low-carbon products that cut chemical input, build healthier soil and grow better crops.
Soil and fertilizer 03
Biochar-grown rice
Starting with healthy rice, we grow green crops with biochar fertilizer and build a supply chain from Chinese fields to international tables.
Crops 04
Balcony potting mix
Low-carbon living also happens on a city balcony. Our biochar-based mix lets households grow fresh, safe food in the smallest spaces.
Potting mix 05
Soil remediation
Large areas of Chinese farmland suffer from acidification and salinization. We use biochar to restore soil structure and fertility.
Remediation 06
China–Europe green hub
Through overseas investment and China–Europe green transition forums, we connect technology, capital and policy across borders.
China–Europe bridge(06) A tonne you can see
Dig 20 cm. The black line is the product.
Most carbon credits are a number on a screen. Ours is a layer in a field you can photograph, sample and measure again in ten years.
Crops and roots
Water and nutrients stay where roots can reach them, so yields hold steadier through difficult seasons.
Topsoil moisture
Biochar pores store water and release it slowly, helping crops ride out dry spells.
The biochar layer
The carbon store itself. Dense carbon that microbes struggle to break down, measured batch by batch and verified independently.
Nutrients and microbes
A vast charged surface holds nutrients and gives useful bacteria and fungi a home.
(07) China–Europe
The first bridge for Chinese removal to the world.
We bring European markets, standards and experience to China, and help China's best low-carbon enterprises reach the global stage.
First international buyer
Kepler Carbon became the first international buyer of the Zhejiang Baguatian carbon removal project, purchasing its inaugural 14 tonnes of credits on the Below2 platform.
A long-term commitment
A vote of confidence in the Chinese market, backed by European resources and government relationships, standing alongside China's environmental enterprises.
Support in both directions
European standards and buyers flow into China. Chinese removal capacity and know-how reach Europe and the rest of the world.
(08) Why Kepler
Three reasons to trust us.
Buyers ask us the same three questions before they sign. Open each one for our answer.
We only develop verifiable, clearly additional, permanent removal. Every credit is backed by a documented chain of evidence that buyers and auditors can follow from field to registry.
From site to retirement, our teams cover project development, digital MRV and trading, and work with independent verification bodies at every issuance. Fewer hand-offs, less lost information.
Our teams and projects span multiple countries. We are fluent in international registry rules and in the ESG procurement standards of multinational buyers, and at home in Chinese agriculture.
