Funding for climate impact

Regenerating the world with care, backed by science

Oncra provides trust in nature-based carbon removal. We certify projects that store CO₂ in land, oceans, rocks and construction materials. We turn project data into verified proof, so carbon removal projects can secure funding faster. Together we are reversing climate change by regenerating life on earth

Funding with Oncra-certificates

Three clear steps that turn carbon removal into trusted climate finance.

Carbon Removal Projects

Inspiring initiatives store CO₂ from the atmosphere by regenerating nature.

Oncra Certifications

Provides trust by efficiently certifying these projects to the highest scientific standards.

Buyers Fund

Carbon removal certificates help buyers fund real carbon removal and help project owners grow their impact.

Are you storing carbon? Get certified and attract the funding your project deserves.

If you grow biobased materials, restore ecosystems, improve soils, farm seaweed or use enhanced rock weathering, your work stores CO₂. Oncra helps you turn that impact into carbon finance, without unnecessary complexity.

Accessible

Built for small and medium-sized projects, with a process designed to be clear, efficient and affordable.

Guided

Our team helps you understand the steps, the data needed and the route to certification.

Credible

Certificates are based on transparent methods, conservative calculations and clear project documentation to the highest EU CRCF and ICVCM standards.

Carbon removal you can trace

Every Oncra certificate is grounded in science and open to scrutiny. You can see where the carbon was stored, how it was measured, who certified it, and what has happened to the certificate since.

Scientific integrity

Each certificate represents exactly one tonne of CO₂ removed, calculated from on-site measurements and certified in line with EU CRCF and ICVCM standards. No rounding up, no estimates without evidence.

Public registry

The Oncra Registry is the public record of every certified project: its location, storage method, measured volumes and the project team behind it. Open to anyone, at any time.

Immutable ledger

The Oncra Ledger records every certificate issued, transferred and retired. The chain of custody is permanent and tamper-proof, so buyers and verifiers always have the full picture.

Oncra's mission is to reverse climate change while regenerating life on earth.

Across nature, soils, oceans, rocks and biobased materials, entrepreneurs are storing carbon and showing what a regenerative economy can look like: one where climate action restores biodiversity, strengthens ecosystems and helps nature recover.

Reducing emissions remains the first priority, but reduction alone is not enough. We also need to remove CO₂ from the atmosphere and store it safely.

Oncra unlocks the value of stored carbon through trustworthy carbon removal certification. We focus on removal only by implementing nature-based solutions. Lean and transparent processes make the Oncra certification accessible to small and medium-sized projects.

By making stored carbon measurable, trusted and fundable, Oncra helps entrepreneurs scale their work and accelerates the transition to a regenerative economy.
