SAN FRANCISCO, Oct. 04, 2022 (GLOBE NEWSWIRE) -- KlimaDAO and Sushi have co-launched a first-of-its-kind carbon offset integration for Sushi's DEX on the Polygon network. The project allows users to "opt in" to compensate for the carbon emissions of a transaction for a nominal fee. Users opting in will offset carbon credits equivalent to 0.02 MATIC per transaction.

The project will also leverage Chainlink Automation to help enable automatic offsetting directly on the blockchain. Chainlink Automation nodes will bundle users' opt-in transactions to be offset at 24-hour intervals by routing through the KlimaDAO retirement aggregator, which executes carbon offsets. This requires no additional activity from KlimaDAO or Sushi to execute the offset, making this a fully automated climate solution deployed on the blockchain.

Decentralized Exchanges are one of the more intensive infrastructures on the blockchain because of the frequency of transactions that they facilitate. From an energy perspective, however, Sushi on Polygon is a lightweight solution, given that Polygon is a Proof of Stake network and Ethereum recently underwent its merge, which has further reduced emissions of the network by an estimated 99%.

Climate Leadership

The project launch comes after Sushi's users previously voted to develop a carbon-offsetting solution for the DEX in collaboration with KlimaDAO. It is part of a broader trend of Web3 projects taking ownership over their carbon emissions and demonstrating that there are the tools and appetite to mitigate climate impacts of blockchain technologies as part of society's shift to a cleaner economy.

This collaboration gives users an opportunity to deliver real-world impact with every transaction. It also shows that green fees can be integrated into web applications and software, giving users the opportunity to unlock more climate finance, at scale.
