Fuel Usage Management
To reduce emissions in line with regulatory requirements, power plants need to add environmental protection equipment and facilities. Coal used must be high in calorific value, low in ash, and low in sulfur content. Since the properties of coal vary from mine to mine and country to country, power plants use blending methods to meet a power plant's requirements for coal ash, calorific value, and sulfur. Taipower has added additional quality requirements for its coal procurement. Further restrictions on mercury content have been imposed. While Taipower exercises strict control of emissions from downstream power plants in its supply chain, the Company works even harder to deliver on its commitments to upstream areas of its supply chain.

Enhancing the Energy Efficiency of Taipower's Operations
Management of Productive Resources
Taipower's total thermal greenhouse gas emissions in 2020 were about 92.66 million tons of CO2e . Its primary sources of greenhouse gas emissions included thermal power generation, coal storage yards, fuel-consuming equipment such as vehicles and engines, insulation gas for power switches, refrigeration and air-conditioning equipment, etc. Although there are no emission restriction or disclosure regulations in Taiwan, the Company's has taken the initiative to limit greenhouse gas emissions by inviting relevant units to conduct inventories and internal verifications each year. Moreover, a third-party notary unit is invited to carry out external verification of thermal greenhouse gas and to publicly disclose that the Scope 1 greenhouse gas emissions of Taipower and its thermal power units (coal, fuel, and gas-fired) are 93.35 million tons.

Non-Productive Resource Management
In 2020, Taipower gave impetus to power-saving in conjunction with the Executive Yuan's Electricity Efficiency Management Plan for Government Agencies and Schools by setting a goal of zero growth in annual power consumption compared to the previous year. Moreover, in accordance with the Ministry of Economic Affair’s Water Saving Normalization Action Plan, Taipower promotes water conservation. The General Management Office will coordinate these efforts while other branches and power plants will be driven through promotions to implement various measures that constituted a comprehensive energy-saving and carbon-reduction scheme. Taipower will also track its energy consumption (paper, water, power, fuel) on a monthly basis and conduct annual assessments to select units with excellent performance.

Results of Non-Productive Resource Management
- In line with the Water Saving Normali- zation Action Plan, Taipower actively promoted the installation of water- saving equipment in offices, at construction sites, and in employee dormitories. Old water-consuming equipment was replaced and water- saving measures such as water-saving advocacy, water management, pipeline facilities leak inspection, and rainwater reclaim and reuse were strengthened.
- In cooperation with the Electricity Efficiency Management Plan for Government Agencies and Schools, Taipower actively promoted the replacement of old energy-consuming equipment (air conditioners, lamps, etc.) in each unit to enhance electricity efficiency.
- Indoor temperatures were kept between 26-28°C in each office and combined with circulating fans to increase comfort levels while reducing the use of air conditioning
- An energy-saving operation control mode for elevators in each building was adopted and elevator operation was suspended during off-peak hours, off-hours, and holidays
- Operated energy-consuming equipment and business machines in all offices in an energy-saving manner; for example, the power supply for water dispensers was turned off automatically during off-hours and regular holidays to save standby power
- High energy-consuming offices, such as the headquarters building, adopted energy management systems to analyze the building’s electricity, equipment operation energy consumption to strengthen energy-saving management results
- Promoted ride-sharing measures in vehicle dispatching and reinforced vehicle maintenance and inspection to reduce fuel consumption
- Drew up a budget to accelerate the replacement of old fuel-consuming vehicles and made good use of electric vehicles
- Saved 4,240 liters of fuel in 2020 compared to 2019
- Continued to implement paper-reduction measures such as electronic exchanges of official documents and online approvals, with the performance reaching 70% and 85%, respectively
- Advocated for employee use of double-sided printing to save 2.37 million sheets of paper in 2020
