A balance sheet for our planet

The need for greater security, transparency, and efficiency within industries such as the carbon markets has never been more pressing. For this market to mature, it is essential that accurate granular data can be logged and accessed without corruption and collusion. Guardian on Hedera combines a trust layer for multi-party data with a digital measurement, reporting and verification tool to strengthen workflows that lead to tokenized quantitative outcomes.

Build, deploy, or access sustainability solutions that take full advantage of Hedera’s low energy network, with world class governance. Read Meeco’s Carbon Markets, Tokenization, and the Enterprise Data Challenge.

Minting and Exchanging Climate Assets

Fees on Hedera are low, fixed, denominated in USD, and paid in $HBAR. This means it is affordable for any organization to mint emission tokens, and for suppliers of offsets to mint carbon offset tokens. Hedera makes it extremely fast and cheap to then transact using these minted tokens.

Trusted, Granular, Transparent Data

Hedera Consensus Service (HCS) provides a platform for increasing trust in data. It is a purpose-built tool for creating decentralized auditable logs of immutable and timestamped sustainability data. Once logged, this granular data can be audited and accessed by all parties increasing confidence and transparency, making it harder to cheat.
