Reductions in annual total emissions of air pollutants achieved by the CBECCS-CrB2 deployment scenario with a mass mixing ratio of biomass of 35%: (A) SO2, (B) NOX, (C) PM2.5, and (D) BC. We present results for six regions in mainland China: North China (NC), Northeast (NE), East China (EC), South Central China (SCC), Southwest (SW), and Northwest (NW). The bars represent the emission reductions from displacing coal-fired power (PC) plants with CBECCS systems and from avoided OBB and DBB.
