I did hear they other day they're finally increasing the cost of emission rights whilst lowering the amount of emissions in the "quota". There's probably a lot of trickery and cheating happening in that area though, like Tesla selling its emissions rights for a billion dollar because they don't have emissions themselves.
Tesla selling right isn’t trickery or cheating. It’s intended - it’s a way to shovel money low-carbon companies so they can develop. Tesla would be long-since bankrupt with that income stream.
