Greenhouse Gas Emissions

Since 2016, EVA Air has been conducting GHG inventories and obtained third-party verification in accordance with ISO 14064-1. Measures cover aviation fuels and GHG sources in our main Taiwan operating sites. In addition, the new ISO 14064-1:2018 has been introduced since 2020, expanding the inventory of Other Indirect GHG Emission Sources. From 2023 onwards, the scope of inventory is expanded to include all operating sites worldwide, including airports/stations and offices. This has resulted in a slight increase in both Direct Emissions from Non-Aircraft and in Indirect Emissions from Energy as compared to the previous year. With rapid recovery in the aviation market since COVID-19 has waned, Direct Emissions from Aircraft Operations have returned to a level similar to that of the pre-pandemic period.

(Unit: tonne CO₂e)		2020	2021	2022	2023
Direct emissions (Scope1)	Aircraft Operations	4,309,738	4,126,548	4,489,390	6,500,804
Direct emissions (Scope1)	Non-aircraft Operations	1,245	571	476	1,188
Indirect Emissions (Scope2)		12,579	12,399	11,990	13,737
Other Indirect Emissions (Scope3)		6,180	7,590	6,935	1,572,839

Note 1: Direct Emissions from Aircraft Operations are total aviation fuel consumption, including training flights, testing flights, and maintenance.
Note 2: Indirect Emissions include externally-purchased electrical power; emission factors are based on the values announced by specific countries. 2022 emissions were revised based on the latest emission factors.
Note 3: Other Indirect Emissions include indirect GHG emissions produced via employee commuting, business trips, and other sources. In 2023, the inventory of GHG emissions from energy among upstream suppliers was folded in.
