Ethereum: Going carbon neutral

The historical emission problem

Before The Merge, Ethereum was widely recognised as a huge emitter of CO2, responsible for a total of 18,100,000 tonnes of CO2 emissions, a significant proportion of global emissions contributing to the climate crisis.

Contracts deployed on Ethereum during the Proof-of-Work (PoW) phase contributed significantly to these emissions.

Transactions occuring since Ethereum's migration to Proof-of-State (PoS) have negligable emissions, but the historical damage has already been done and a significant climate debt is owed.

How Seedchain can help

Seedchain allows developers to understand the historical emissions of their contracts and offset them to become carbon neutral.

A bottom-up impact calculation of pre-merge transactions (based on the seminal work by Kyle McDonald) provides an easy-to-understand estimation of any contract's CO2 emissions.

On-chain offset minting allows contract owners to offset their emissions on a one-off basis, or by integrating Seedchain into their contract. All impact is provided by verified suppliers.

Beyond carbon neutral

Contracts can continue to reduce CO2 to become carbon negative. Additionally, impact tokens can plant trees to help restore ecosystems.

Collectively we can change Ethereum from a net-negative for the planet to a net-positive.

Benefits of using Seedchain

  • Reach net-zero CO2 emissions for pre-merge transactions
  • Become a carbon-sink by offsetting more than you emitted
  • Restore ecosystems
  • Purchase impact on-chain via a wallet or contract
  • Audit the impact of any address via the Ethereum blockchain

Specific benefits for NFT collections

  • Assign impact to specific NFTs
  • Airdrop impact to holders
  • Integrate Seedchain with on-chain mechanics like minting (i.e integrate with minting to donate 1% of proceeds to offsets).

Ways to reach net-zero emissions

This is a non-exhaustive list of ways you can offset your existing emissions with Seedchain. It's reasonable to use one approach, combine different approaches or create a new approach entirely.

One time purchase

Anyone can make a one time purchase of Seedchain tokens. These tokens can be minted to the wallet making the purchase or airdropped to another wallet. If you're the owner or deployer of a contract, you can mint on the contract's behalf.

NFTs: Contribute a percentage of secondaries

Example: 1% of royalties go to offsetting CO2

NFT projects that take royalty payments on secondary sales may choose to contribute a portion of this to purchasing impact. This enables a gradual offsetting over time.

This can be baked directly into the contract for a specific address, purchased by the owner/deployer or via a proxy address.

NFTs: Offset individual tokens

Example: Every time a token is sold, 1% of the sale price offsets the carbon emissions of that token.

NFT collections have numerous tokens which may each have different historical carbon emissions. You can choose to offset emissions for individual tokens, visualised on the NFT's impact report.

See example NFT impact report

NFTs: Percentage of mint

Example: 1% of mint proceeds goes to planting trees.

NFT collections that are currently pre-mint may choose to integrate Seedchain directly into their minting function. This enables impact to be purchased during the minting phase.

Other contract integrations

The Seedchain contract API enables web3 developers to integrate Seedchain into their contract in whichever way works for them.

Here are some suggestions:

  • Purchasing trees from leftover funds after a token swap
  • Wrapping Seedchain tokens to create a new asset class
  • Wrapping Seedchain tokens to create a dynamic NFT that evolves based on the impact created


Why is Seedchain on Ethereum?

Seedchain is built on Ethereum. This is only now possible due to the negligable carbon emissions after the Proof-of-Stake merge.

Being on Ethereum means:

  • Impact is associated directly with the address of your contract
  • Anyone can review the impact you've minted via the Ethereum blockchain (or via the Seedchain platform)
  • You can airdrop Impact Tokens directly to other Ethereum addresses (such as holders, if you're an NFT project)
  • You can integrate Seedchain deeply into your contract using our contract API, enabling you to make your transactions implicitly carbon negative
  • You can wrap Impact Tokens to create entirely new experiences based on climate action

Fundamentally, the impact is the most important thing, and we're happy whether or not that's done via Seedchain or another provider.

Is this a donation?

No. We are all stakeholders in the future of our planet.
