11	Introduction
12	The following analysis summarizes the greenhouse gas (GHG) emission footprint of the Solana blockchain network. This analysis is based on publicly-available emissions intensity data, which is limited in the large majority of locations worldwide. As such understanding of Solana's climate footprint will never be perfect, but by developing with community feedback and overestimating climate emissions where necessary, this effort seeks to drive more thoughtful and impactful decisions related to blockchain and climate change. As the Solana validator network expands and evolves this footprint also change over time. In addition to provide network transparency, releasing and improving this data in collaboration with the Solana community will also ideally provide a valuable service to a range of other stakeholders, who can use improved public data and discussion on factors such as grid electricity carbon intensity to tackle their own questions and challenges.

15	March 2022 Update Highlights
16	- Validator count rose to 1,762, up from 1,470 in Dec 2021
17	- As the validator network shifted toward locations with lower carbon electricity, network average carbon intensity fell to 198 g CO2 per kWh, down from 201 in Dec 2021.
18	- As the total number of validators increased, estimated network emissions rose to 2,976 tonne CO2 per year, up from 2,524 in Dec 2021.
