To get the climate round estimate, my plan was to:

Gitcoin chose to use the methodology employed by carbon.fyi to assess the climate impact Grants Round 12 activity on Ethereum mainnet.
Carbon.fyi provides a thorough, well-explained methodology for estimating the carbon footprint of Ethereum transactions.
For Gitcoin’s estimation, we included:
|Gas consumed by all the transactions sent to the https://etherscan.io/address/0x7d655c57f71464b6f83811c55d84009cd9f5221c contract on Ethereum mainnet between Block 13722253 and Block 13819261, the duration of GR12.||359994125|
|Gas consumed by the grants claim https://etherscan.io/address/0x0EbD2E2130b73107d0C45fF2E16c93E7e2e10e3a. There were a similar number of grant projects in GR12, so they felt this was a reasonable proxy.||30249823|
| http://carbon.fyi’s HIGH estimate for CO2e emissions per unit of gas | 0.0003895583921 | | Multiply total gas x CO2e emissions per unit of gas | ~152,022.80 kg CO2 emitted |
<aside> 💎 152.0 metric tonnes of CO2e emitted from GR12 mainnet activity
