Thus, the speed of reducing power sector CO2 emissions in the power sector was explored from a systems perspective to assess the effects on the energy mix and associated technologies, resulting CO2 emissions, other emissions (PM, SOx, NOx) and total system costs for a range of increasingly ambitious CO2 scenarios. The analysis showed that with increasing CO2 ambition, system costs increase but not as much as initially expected – clearing a path for power sector decarbonization with minimal tradeoffs and substantial power sector benefits.enCO2 ambitionCoal fleetDemand forecastEnergy Availability Factor (EAF)Solar PVWater useTotal system costWindCCSNuclearFlexibilityReportWright, J.
