If 'carbon negative' and 'carbon positive' are terms used interchangeably to mean completely opposite things, what are alternative terms that clarify the difference without confusion?
For example, could alternative terms like "carbon reducing" and "carbon increasing" make it more clear and avoid misinterpreting which means which?
It sounds like OP has heard people say "carbon negative" to mean that something outputs more CO2 than it consumes, and vice versa, which is contrary to how I hear the terms used.
