I would argue carbon offsets are exactly doing their job: allowing people and corporations to throw a bit of money at the problem and continue with business as usual.
The job we have to do is rapidly decarbonize our economy and also remove billions of tons of carbon already in the air. This pursuit is likely in the trillions of dollars in our lifetime.
Existing carbon offsets are best thought of as an attempt. The opportunity is, what's next? What's going to actually solve this multi-trillion dollar problem?
They are the equivalent of medieval indulgences.
