In the past two years

data fraud problems appeared in carbon emission statistic process relying on manual reports in fossil-fired power plants

exposing the deficiencies in data quality control during the carbon emission statistic in China. Therefore

it is an inevitable trend to gradually improve the quality of carbon emission statistic and quality control mothod. Based on the coal power and gas power enterprises

the main differences between carbon emission statistical methods and data quality requirements are analyzed by comparing the domestic and foreign current standards. The classification and implementation methods of carbon emission statistic in Europe and the United States are summarized

and the carbon emission statistic and quality control requirements in China's latest standards are also introduced. It is found that the continuous monitoring method has been applied in Europe and the United States

while only the emission factor method is applied in China. Quality control of data is based on multiple indicators with various contents in China

but relies on a single indicator in Europe and the United States respectively. Finally

it is pointed out that it is an inevitable trend to establish comprehensive

scientific and united data quality indicator and limits in China to keep in line with the trend of the international carbon trading market.
