Fig. 4: Potential benefits of emission reduction technologies and the impacts on co-benefit values.
From: Location-specific co-benefits of carbon emissions reduction from coal-fired power plants in China
a Potential benefits of four emission reduction methods in reducing health costs per kWh electricity generation. b Impacts of four emission reduction methods on co-benefit values per ton CO2 emission. The four representative methods to reduce emissions are (1) flue gas desulfurization (FGD); (2) selective catalytic reduction (SCR); (3) switching from electrostatic precipitators to fabric filters (FAB); and (4) switching from high-sulfur coal to coal with the national average sulfur content. “Residue” represents the value under the ideal situation when all methods are perfectly adopted. The black and yellow diamond-shaped dots represent the actual provincial values in 2017.
