Ethereum Carbon Emissions Calculator

Made with ♥ by Offsetra.com for carbon.fyi. License: MIT.

JavaScript utility to calculate the CO2 emissions of any Ethereum address.

The tool is written in TypeScript and powered by the the Etherscan.io API & an open-source carbon accounting methodology under development by Offsetra. We hope this tool is useful for raising awareness and understanding with regards to the rapidly growing carbon emissions of cryptocurrency mining.

Questions, comments, forks and PRs all very much appreciated!

Usage

npm install ethereum-emissions-calculator

Provide an address and a transaction type, and the calculator will tell you how many emissions this represents in KG CO2e. To calculate the sum total of your addresses' lifetime emissions, you must combine the sum of eth, erc20, and erc721 emissions.

import { calculateAddressEmissions } from "ethereum-emissions-calculator";
import { address, etherscanAPIKey } from "data";

const emissions = await calculateAddressEmissions({
  transactionType: "eth", // "eth" | "erc20" | "erc721"
  address, // 0x12345[...]
  etherscanAPIKey,
});

console.log(emissions);
// {
//   transactionType: "eth",
//   kgCO2: 12345`,
//   transactionsCount: 69,
//   gasUsed: 420,
// }

Methodology

Emissions are calculated based on the transactions initiated (sent) by the provided address. The total emissions are derived from the amount of gas used for each transaction.
