No More Double-Counting
Once a carbon credit is retired on MST, the record is permanently locked. It cannot be re-used, re-sold, or claimed by any other party , ever.
Carbon CreditTracking
No more double-counting. No more greenwashing. Carbon claims that are actually provable.
What is Blockchain Carbon Credit Tracking?
A carbon credit represents one tonne of carbon dioxide reduced or removed from the atmosphere. Organizations buy these credits to offset their own emissions. The problem is that existing carbon markets are opaque , credits get double-counted, retirement records are unreliable, and organizations cannot always prove that the credits they bought are genuinely retired. MST Blockchain solves this by creating a transparent, permanent, publicly verifiable record for every carbon credit from issuance through to retirement.
Verifiable Sustainability Claims
Organizations can prove their carbon offset claims by pointing to specific on-chain retirement records , accessible to regulators and the public.
Full Lifecycle Transparency
Every credits journey from issuance through transfer to retirement is permanently visible. Buyers know exactly what they purchased and where it came from.
The Problem: Carbon Markets are Riddled with Credibility Issues
Studies have found that a significant portion of carbon credits sold on voluntary markets do not represent genuine emission reductions. Credits get double-counted across different registries. Retirement records are easy to manipulate. Companies claiming carbon neutrality often cannot actually prove that their purchased offsets were genuinely retired. This undermines the entire purpose of carbon markets and erodes public trust in corporate sustainability claims.
How MST Fixes It
Every carbon credit issued on MST gets a unique on-chain token representing one tonne of verified CO₂ reduction. Every transfer between organizations is recorded. When a credit is retired, the retirement is permanently locked on-chain , it cannot be used again, transferred, or claimed by anyone else. External data sources like satellite imagery, IoT sensors, and third-party auditor reports can be fed into the system via WASMify to verify the underlying emission reduction activities.
