The total emissions are derived from the amount of gas used for each transaction. See https://carbon.fyi/learn

The emission table needs periodic updating until Ethereum goes carbon neutral. Download .csv gas used data from https://etherscan.io/chart/gasused and hashrate data from https://etherscan.io/chart/hashrate

To generate up-to-date emission data, run npm run update-emissions-data

Data is output to src/data/emissionsFactorTable.json as a set of 2-week average emissions factors (kilograms-co2-per-gas).
