Just by reading the abstract this seems a bit strange. Ok, they identify some of the worst CO2 emitters and propose to start tackling those. But then their proposal is that these "lowered their emission intensities, switched to gas fuels, and incorporated carbon capture and storage systems." Like they propose three things that still depend on fossil fuels, from which one is vague, one is something that hasn't worked anywhere although it's been proposed as a solution for more than a decade (CCS) and one that at best provides minor emisison reductions if looking at full lifecycle emissions (gas).
