Managing Climate Change Risk

To meet global aviation industry's climate target and in response to the frequent climate incidents in recent years, TIAC implemented the Task Force on Climate-Related Financial Disclosures (TCFD) instructions formulated by Financial Stability Board in 2020, to preemptively handle climate change risks management. TIAC applied and received a TCFD conformity statement from an international third-party verification institution, making it the first in the global aviation industry.

Managing Climate Change Risk

Based on the TCFD framework, we conducted climate change risk assessments and identified nine climate-related risks. Through cross-analysis of the possibility of occurrence and the degree of operational impact, the impact hazard has been estimated as below. The degree of impact is shown by size of the circle in the matrix chart, focusing on three high risks and one moderate risk items.

First in the global aviation industry to receive a TCFD Conformity Statement
Climate change has become an inevitable global trend. ICAO also called on the aviation industry to reduce its carbon emissions by 50% in 2050 compared to 2005. To effectively implement climate change mitigation and adaption, and to achieve the goal of a Sustainability and Safe Airport, TIAC applied and received a TCFD conformity statement from an international third-party verification institution, making it the first in the global aviation industry. TIAC hopes to, by its influence, drive the domestic aviation industry and state-owned enterprises in the nation to achieve sustainable development goals together.

Energy Usage

In order to reduce emissions and create an eco-friendly environment, the company has since 2016 implemented a vehicle electrification plan. In 2020, TIAC purchased three hybrid electric vehicles. In the future, TIAC will prioritize electric vehicles to reduce fossil fuel usage and GHG and air pollutants emissions. Since 2020, entrance passes for the underground luggage handling area are only issued to electric vehicles. Starting 2021, only electric vehicles will be allowed to pass through said area. TIAC continues to obtain ISO 50001 energy management system verification every year. While diesel fuel usage grew in 2020 due to the use of portable emergency generators, all other products dropped significantly compared to previous years due to the pandemic. Energy usage and heating values for the past three years are shown in the following table:

Greenhouse Gas Management

With great focus on the issue of GHG emissions, TIAC takes stock and inspects its GHG emissions every year and has obtained ISO 14064-1 external verification. The company's GHG emissions for the past three years are shown in the following chart. The amount of unit emission per passenger rose in 2020, resulting from the significant drop in passenger volume caused by the pandemic. Airports Council International (ACI) had announced that GHG emissions data of 2020 will only be used for future reference and will not be used for evaluations. In the future, TIAC will continue to act proactively in response to energy-saving and carbon-reduction trends through various relevant projects.

Greenhouse Gas Management over the past three years

Waste Management

Waste from TIAC is mainly composed of two categories: the first being old equipment and utensils, and trash from passengers and employees (for example bottles, metal cans, and glass); and the second being trash removed from airplanes by airlines operators. As trash on the airplanes comes from abroad, they are processed through an incinerator especially installed for this purpose at TTIA to prevent infection from foreign bacteria. This incinerator also takes care of combustible trash from airport terminals, duty-free shops, restaurants, and different airline operators. The average daily waste managed through this incinerator is around 30 to 40 tons.

Waste Management

Air Quality Management

Air quality in all spaces is carefully monitored, including in arrivals and departure halls, dining areas, and all stores. And we advocates the use of public transportation, works to reduce idle vehicle time, and has electrified all airport vehicles to lower air pollution levels in surrounding regions.

Water Resource Management

Household and irrigation constitute the bulk of water usage in TIAC; the said usage mainly stems from passenger and employee cleansing, plant maintenance, and water for cleaning airport buildings and grounds. Most water used are from tap water supply system; there is no large-scale usage of natural waters or underground water. Wastewater generated in airport toilets are carefully recycled and retained to water the 4,200 trees on airport grounds following processing through sewage treatment plants. As for drinking water equipment and pressurized water tanks, TIAC implements maintenance and management measures including advanced prevention, enhancement of monitoring efficiency, as well as standardized procedures for handling abnormal items. These highly important measures not only enhance service quality and water supply efficiency, but also reduce waste of water resource right at the very source. In addition to enhance service quality, improve the water supply efficiency and to manage the usage of water from its source to reduce waste, TIAC added recycled water meters in 2020, with a total recycled water volume of 20,962 tons and a recycling rate of 0.58%.

Noise Monitoring and Management

Takeoff and landing volumes are closely monitored by TIAC and specific areas have been designated for test runs and engine testing. Additionally, test runs are prohibited from 00:00 to 06:00. Apart from aircraft pushback procedures, TIAC also forbids the use of auxiliary power units (APUs) at the northeast aircraft bays for cargo planes to reduce the impacts of airport noise on residents.

Currently, TIAC has a total of 18 fixed monitoring stations in the Luzhu, Dayuan, Guanyin, Xinwu, and Zhongli districts to monitor noise. Professional personnel were invited to conduct comprehensive analysis of wind directions, seasons, ground noise, and aviation noise; this information was further used to compile quarterly noise monitoring reports. TIAC allocates "rebates" and "noise control fees" to the Taoyuan City Government each month to handle aviation noise prevention and distribution of rebates, and provide references for planning of aviation noise control zones. Apart from the aforementioned measures, TIAC proactively maintains close relations with local governments and residents to fulfill its mission of inclusive society.
