Greenhouse Gas Emission Inventory and Registration Deadline Extended due to COVID-19


Due to the severity of Covid-19 in Taiwan, the Central Epidemic Command Center recently raised the national epidemic alert to Level 3. To be in line with the nation’s fight against the epidemic and to reduce public outings to lower the risks of infection, the EPA has extended the deadline for greenhouse gas emission inventory and registration to the end of September this year (2021).

Since the promulgation of the Greenhouse Gas Reduction and Management Act on 1 July 2015, the First Batch of Emission Sources Required to Report Greenhouse Gas Emission Inventory and Registration has been announced. Industries including power generation, iron and steel, petroleum refining, cement, semiconductor and thin film transistor liquid crystal display, as well as emission sources with annual emissions of more than 25,000 metric tons of CO2e from combustion of fossil fuels are subject to the regulation. They are supposed to complete the inventory and registration of greenhouse gas emission of the previous year of their entire plant (site) by the end of August every year.

According to the EPA, the average number of enterprises that are required to make inventory and register their greenhouse gas emissions is 288 over the past five years. Among them, direct emission sources included emissions from combustion of fuels (80.70%), emissions from manufacturing processes (18.98%), emissions from fuels used for transportation vehicles (0.03%), and fugitive emission sources (0.29%). Indirect emissions included power consumption (87%) and steam consumption (13%). Ranked by industries, the power generation industry had the highest emission (53%), the second highest are the steel industry (14%), basic chemical material manufacturing (11%), petroleum refining industry (9%), cement industry (4%) and semiconductor industry (2%). Analyzing the changes in manufacturing greenhouse gas emissions in the past five years, the semiconductor industry has the highest average annual growth rate of 6.44%, the paper industry is 1.35%, and the optoelectronics industry is 0.37%; the average annual growth rate of the remaining industries is on a downward trend.

As for the electricity industry, the electricity emission factor (the carbon dioxide equivalent emitted per kilowatt-hour of electricity) decreased from 0.525 kg CO2e/kWh in 2015 to 0.509 kg CO2e /kWh in 2019; while the greenhouse gas emissions of the power industry decreased from 115.68 million in 2015. The metric tons of CO2e rose to 119.57 million metric tons of CO2e in 2019. Therefore, the electricity emission coefficient decreased in 2019, but the greenhouse gas emissions showed an upward trend. According to statistics from the Bureau of Energy of the Ministry of Economic Affairs, the industrial sector accounted for about 56% of the electricity consumption in 2019, and the service industry and the residential sector each accounted for about 18%. This shows that energy-saving in the residential and commercial sector is also an important part of reducing greenhouse gas emissions in the power industry.
