How Carbon Compared Works
We help businesses and individuals evaluate, compare, and invest in high-quality carbon removal projects.
Our Process
Carbon Compared provides a standardised approach to evaluate and compare carbon removal projects.
1. Project Verification
We carefully verify all carbon removal projects, ensuring they meet our standards for permanence, additionality, and verification.
2. Standardised Metrics
We analyse each project using consistent metrics including cost per ton of CO₂, storage duration, removal method, and co-benefits.
3. Transparent Results
Access detailed comparisons and analysis to make informed decisions about which carbon removal projects align with your goals and values.
Compare Carbon Removal Projects Side-by-Side
Our interactive comparison tool lets you evaluate verified carbon removal projects across multiple dimensions to find the perfect match for your net-zero sustainability goals.
Multiple Quality Metrics
Compare cost per tonne CO2, permanence duration, BeZero integrity ratings, additionality, and global location all in one comprehensive view.
BeZero Verified Quality
All carbon removal projects undergo rigorous BeZero verification to ensure high integrity, permanence, and real climate impact for your net-zero goals.
Global Carbon Markets
Carbon removal projects from around the world, spanning direct air capture, biochar, enhanced weathering, and nature-based solutions.

Purchasing Carbon Credits: A Strategic Guide
Navigating the voluntary carbon market to purchase carbon credits for your organisation requires a strategic and informed approach. Carbon credits, when used responsibly and chosen carefully, can be a valuable tool to address residual emissions and contribute to global climate goals. However, the market is complex, with varying quality and impact among projects. This guide outlines key factors to consider when choosing which carbon credits to buy, ensuring your investments are effective, credible, and aligned with your broader sustainability objectives.

UK Paves the Way: Carbon Removals Set for Integration into Emissions Trading Scheme
In the longer term, the Authority recognises the potential benefits of moving to a net cap, where only emissions allowances are capped, allowing removal allowances to enter above this limit, which could underpin an economically efficient approach to net zero once the GGR market matures and residual emissions are largely hard-to-abate.

Key Terms
Common terminology in carbon removal
Additionality
The principle that carbon removal or emissions reductions would not have occurred without the incentive of carbon finance. Essential for ensuring carbon credits represent real climate benefits.
BeZero Rating
Independent risk assessment of carbon projects using satellite data and AI analysis. Provides ratings from AAA to D based on additionality, permanence, and overestimation risks.
Biochar
Stable carbon created through pyrolysis of organic materials. Provides long-term carbon storage while improving soil fertility and agricultural productivity.
Buffer Pool
Reserve of carbon credits set aside to cover potential reversals or overestimation in carbon projects. Provides insurance against project risks and uncertainties.
