Environmental Sustainability

The aviation industry's operations comprise two major components: flight operations and ground operations. Greenhouse gas (GHG) emissions from aircraft account for more than 99% of EVA Air’s Scope 1 emissions. Since 2016, EVA Air has conducted annual GHG inventories in accordance with ISO 14064-1 and obtained third-party verification. The inventory initially covered emissions from aviation fuel consumption and company-owned buildings in Taiwan. Since 2023, the organizational boundary has been expanded to include all operationally controlled facilities worldwide, including domestic and overseas stations and city offices. In 2025, EVA Air continued to conduct its GHG inventory in accordance with the GHG Protocol and obtained third-party assurance.

Over the past two years, growing demand in the international aviation market led to an increase in flight operations and fuel consumption, resulting in higher Scope 1 emissions. Meanwhile, Scope 2 emissions decreased due to effective electricity-saving measures and increased use of renewable energy.
