This is what EU as a whole does (reduce CO2 by X% within Y years), e.g., the 2030 climate targets. However, there is a very strong correlation between reaching those targets and the broad/accepted definition of renewables. Again, I understand you're trying to be more precise and all that, but in the broader language the connection is "renewables = reduction of CO2 in a sustainable way with solar panels, wind, etc etc". EDIT: ok, I forgot, there would be the nuclear energy as well to reduce CO2, which is not really renewable (although most of it can be recycled it seems). You were right. I would still prefer 100% renewable (and have no burning fuels at all) but I would be happy to have a mix of renewable and nuclear to reduce emissions and still keep companies up and running (=cheap electricity).
