Want to offset all your Ethereum transactions?

Tell us your Ethereum address. We'll pull the transaction history from Etherscan and calculate the carbon footprint of all transactions.

Don't be sad!

Some numbers for you to chew upon

You can find the sources for our calculations here

Energy used for a standard
ERC20 token transaction
[ ~ 37000 gas ]
> 15 kWh / tx
Carbon footprint for this
ERC20 token transaction
[0.36gCO2 / gas]
> 13 kgCO2 / tx
Cost to offset this
ERC20 token transaction

What's this all about?

We tokenize carbon offsets to make them available for Ethereum's web3 ecosystem.

If you're a conscious consumer: use this app to offset your carbon emissions directly.

If you're a developer: our Solidity modifier can be integrated to any smart contract to calculate and automatically offset the emissions associated with its execution, and a JavaScript API allows dApps to interact with our smart contracts to offer their users carbon offsetting

This is only the beginning: we have a bold long-term vision for democratizing and increasing transparency along the carbon offset value chain, creating a carbon-neutral web3 and beyond 🦜
