The only realistic way to "bear the cost" of CO2 emissions is paying for getting atmospheric carbon back into the ground. Right now that seems difficult to do at scale. The best way I know is making charcoal and burying it. Offsetting 1kWh needs on the order of 200g of wood turned into charcoal and buried.

Are you suggesting we cut down trees and bury them to save the planet? For me, this idea marks the departure from reason and into crazytown.

When our civilisation is excavated in 500 years, they are going to say we were as crazy as all of the others.

I don't think it's necessarily unreasonable. As I understand it, the lumber industry has optimized the ability to grow massive amounts of fast growing pine as quickly as possible. So this isn't suggesting that we start clearcutting forests, it's suggesting that we start growing massive amounts of lumber with the explicit purpose of converting it to charcoal and burrying it.

I suggest it’s easier to leave to carbon in the ground in the first place. Carbon capture promises are unrealistic. But if you want to go with charcoal it’s probably best to get wood from coppicing.

Making charcoal releases CO2 though? How does that help with carbon capture?

You don't HAVE to make it into charcoal, but it will take up way more volume if you don't and contains tons of volatiles like methane that will come out and may make the ground less stable to simply bury with dirt as it partially rots.

Theoretically you could harness some of those volatiles for some energy production, but at the very least use those volatiles to heat the wood and make it charcoal for basically free.

Methane is a significantly more effective GHG than carbon dioxide!

Charcoal is like 80% carbon and the tree extracted it from the atmosphere.
