To truly reverse the emissions an individual or company has, Carbon Removal is really the only way.
Carbon credits _can_ encourage businesses to reduce their emissions (and if a company has money to help - great!) but reducing a third-parties emissions is not a green-light to justify my own wrongdoings.
If I emit a ton and pay credits to offset a ton, a ton is still out there. If I emit a ton and remove a ton I am at net zero emissions.
