The CEAP is the first database using systematic, detailed, real-time monitoring data from Chinese newly installed national Continuous Emission Monitoring Systems (CEMS) network to estimate nationwide, unit-based, time-varying emission factors and absolute emissions of SO2, NOX and PM from Chinese power plants. The CEAP addresses the limitations of existing database from the following three perspectives. First, because the CEMS network targets stack concentrations of different air pollutants (also the targets of the new ULE standards), which allows us to determine the compliance behaviour of Chinese power plants and the associated impacts. Second, the use of actual measurements allows for a direct estimation for power emissions without using many assumptions and intermediate parameters in previous estimations but with accounting for changes in fuel composition, operations and maintenance, technology detail, technology upgrades and weather conditions that can affect actual emissions, which largely reduces the uncertainty on estimates. Third, the real-time (hourly) measurements by CEMS present dynamics of the polluting behaviours of Chinese power plants and the compliance behaviors with the ULE standards over time.
