I accept the argument that offset schemes have difficult practical problems, but at least theoretically “offset” means “lower”. It just means that your application isn’t necessarily reducing carbon. And it kind of makes sense—for an airline to get carbon neutral it would require immense investment in electric flight and decades of research and then more decades of incremental rollout. Instead that money and effort could be spent helping reduce a lot more carbon elsewhere now (e.g., replacing coal power plants with equivalent solar power).
