The idea of holding individuals and small organizations responsible for their carbon use is a deliberate eco-fakery invented by the fossil fuel industry. It does nothing, except in cases where it leads to purchasing "carbon offsets," in which case it does nothing and also makes some scammer somewhere some money.
Most big changes that need to happen are on the industrial level (switching to different sources of electrical power or changing pollution regulations). They may have some impact on the end-user consumer, but mostly not. Mostly what it would mean is that some obscenely rich person still gets to be obscenely rich but not as much as they want to be.
(AI and cryptocurrency are rare arguable-exceptions where the power consumption is actually pretty significant and you can make a case that the individual involved in it bears some responsible for the impact. But again, the strategy should be for the individual to advocate for changing regulations, not for the individual to look inward towards themselves but turn a blind eye to everyone else who decides to murder the planet, if they want to because there's some money in it for them.)
