The world’s first open data carbon certifier
Every certification is backed by real-world data that anyone can independently verify — transparent by design, not by exception.

RTD Ratings is the world’s first open data sustainability certifying agency — reflecting our twofold commitment: data quality and data transparency.
Our open-data Carbon Registry platform provides transparent and verifiable data on carbon projects and credits.
RTD stands for Real Time Data. Our certifications are based on real world data and high-frequency data feeds — in some cases real-time or near real-time.
Ratings: We make transparent certifications so the markets can make transparent ratings. Open data certifications enable markets to better evaluate, monitor, rate, and rank sustainability solutions.
RTD audits and verifies trusted marketplaces that trade carbon credits generated by RTD-certified projects. Every platform on this list has been independently reviewed.
