State-Run/Owned Enterprises Reach Excellent Carbon Reduction Results Under the EPA’s Supervision


The EPA continues to cooperate with the Ministry of Economic Affairs (MOEA) on the inventory of carbon reduction achievement by state-run enterprises. Take Taichung Power Plant as an example, the air pollution emission of this plant in 2018 is 23% less than that in 2016, a result from implementing measures like reducing coal and increasing natural gas use, installing wet electrostatic precipitators on existing coal-burning power generators, improving coal pulverizers, updating gas desulfurization equipment, and improving catalytic denitrification equipment. It is estimated that the reduction in 2020 can reach 48%, which is better than the result from simply cutting down the coal use by 40%.

Besides Taichung Power Plant, the EPA emphasized that Dragon Steel Corporation (DSC) in central Taiwan has also completed projects, including enhanced coke oven gas desulfurization, installation of dust-collection equipment on coke conveyor system, and automatic temperature control projects in hot rolling mills. DSC will continue to work on projects to bring material piles indoors and improve control equipment.

Through pollution reduction inventorying, the EPA has promoted various air pollution prevention and control projects in state-run/owned enterprises, such as TaiPower, China Steel Corporation, China Petroleum Corporation, Dragon Steel Corporation and China Ship Building Corporation. From 2016 to 2019, air pollution reduction of over 9,000 metric tons have been achieved. As a result of these and other pollution measures, concentrations of air pollutants in counties and cities throughout Taiwan were shown to be on a downward trend. In addition, in order to ensure that state-run/owned enterprises implement air pollution control and improvement tasks according to the planned schedule, the improvement tracking and review meetings originally presided by the MOEA are presided by both the EPA and MOEA as of the first quarter of 2020. This was to enhance the administrative supervision and reviewing capacity for strict monitoring of air quality improvement efforts.

Take the air quality in Taichung as an example, the EPA noted that it has seen significant improvement as the number of monitoring stations showing red alert days (average daily PM2.5 concentration≧54µg/m3) was lowered from 71 stations in 2016 to five stations in 2019, a 93% drop. And the monitoring data has shown the average PM2.5 went down from 21.8μg/m3 in 2016 to 17.2μg/m3 in 2019, a 21% improvement. All show that Taiwan’s air pollution control strategies have been effective leading to continual air quality improvement.

The EPA emphasized that coal reduction is not the only means to reduce air pollution, and it will continue to strengthen the promotion of different control measures under the authorization of the Air Pollution Control Act. These measures include source control measures such as setting fuel composition standards, management and preventive measures such as improving fuel use permit and stationary source operation permit management, and end-of-pipe control measures such as reviewing and tightening emission standards for different industry categories and pollutant types. Along with these measures the EPA will also promote the best available control technologies and the designated pollutant reduction system for existing pollution sources in Class 3 control regions. The goal is to maximize emission reduction through multiple means and improve overall air quality. By reviewing control measures, the EPA also aims to integrate the capabilities of government agencies and strengthen the cooperation between the central and local governments.
