Carbon & energy use
|Updated||Emissions estimate||Offsets puchased|
At the time of writing this, the Ethereum blockchain is still using proof of work to confirm transaction blocks. Since proof of work rewards using as much energy as possible, I'll keep a running tally of transactions done with my pieces, and periodically purchase carbon offsets to a multiple of their estimated kgCO2 impact. This is not a perfect solution, but I see it as the minimum I'm willing to live with.
