Getting Started
What is Carboful?
Carboful is a transparent, accessible marketplace that makes it simple for businesses of any size to purchase verified carbon credits. Unlike traditional carbon brokers that require minimums of 10,000+ tonnes, we specialize in smaller, flexible purchases—making carbon offsetting accessible to SMEs, startups, and growing companies.
Our platform connects you directly to high-quality, verified carbon removal and reduction projects from around the world. Every credit is traceable, independently verified, and comes with full documentation from recognized international registries.

Verification & Compliance
Recognized International Registries
Every carbon credit on Carboful comes from a registered and independently verified project listed with internationally recognized carbon registries. We partner with the world's most trusted standards bodies to ensure the highest levels of integrity.
Primary Registries
- Verra (VCS) – Verified Carbon Standard
- Gold Standard – Highest quality offsets
- Climate Action Reserve (CAR) – North America focused
- American Carbon Registry (ACR) – US-based projects
Every Credit Includes
- Registry Name – Which standard verified the project
- Project ID & Serial Number – Unique identifier
- Vintage Year – When emissions were reduced
- Registry Link – Direct verification on official registry
Our Due Diligence Process
Before any project is listed on Carboful, our team conducts rigorous due diligence to ensure it meets our strict quality standards. We evaluate three core pillars:
Project Quality
We verify that each project aligns with recognized international standards (VCS, Gold Standard, CAR, etc.) and has undergone third-party validation. Only projects with robust methodologies, clear documentation, and proven impact make it onto our platform.
Additionality
We ensure the project would not have happened without carbon finance. This means the carbon reduction is genuinely "additional" to what would have occurred anyway—a critical requirement to ensure real climate impact.
Permanence
For removal projects, we verify long-term carbon storage mechanisms and risk management protocols. This includes buffer pools, monitoring requirements, and reversal insurance to protect against future carbon loss.
Pricing, Custody & Retirement
How Pricing Works
Our pricing is transparent and based on real market dynamics. Several factors influence the cost per tonne:
- Project Type – Removal projects (e.g., direct air capture) typically cost more than reduction projects (e.g., renewable energy)
- Vintage Year – More recent vintages often command higher prices due to perceived quality
- Certification Standard – Gold Standard and Verra projects may have premium pricing
- Market Supply – Current availability affects pricing in real-time
No hidden fees. The price you see is the price you pay—inclusive of platform fees and registry charges.
Custody & Retirement
Understanding how your credits are managed from purchase to retirement:
Before Retirement
Upon purchase, your credits are held in secure custody under Carboful's registry accounts. You own the environmental claim, but the credits remain unretired until you're ready to use them for offsetting purposes.
Retirement Process
When you retire credits, we permanently remove them from circulation on the official registry on your behalf. This ensures they can never be resold or double-counted. You receive a retirement certificate with the unique registry serial numbers.
Documentation
All retirement records are publicly verifiable through the registry's website. We provide you with direct links and downloadable certificates suitable for sustainability reporting and compliance needs.
100% Transparent. Every transaction is traceable and backed by official registry documentation.
