Well no, but it's either pedantic or meant to mislead. If we're in agreement we need to do something about CO2, then we both know we're talking about human sources of CO2, so why be pedantic?
Telling people to not emit carbon dioxide from, say, a health related usage (sanitation) IMO is foolish when we can choose to sequester from other areas. Frankly I think we need to focus on the decarbonization of energy, rather than regulating human behavior.
