Greenhouse Gas Inventory

In response to the government's net zero policy, since 2022 ECOVE has conducted comprehensive greenhouse gas emissions inventories annually for subsidiaries included in its consolidated financial statements. For subsidiaries over which it holds operational control across various sectors, ECOVE conducts organizational greenhouse gas inventories and obtains third-party verification. In addition, the Company applied for carbon footprint certification for its waste incineration treatment services, taking it as the Company's mission to provide lower-carbon services. Currently, there are four energy
and resources centers that have obtained product carbon footprint certification: Keelung, Miaoli, Xizhou, and Gangshan.
　
Using the year 2022 as the base year, ECOVE Headquarters has set reduction targets as follows: a 20% reduction by 2024, a 40% reduction by 2026, and achieving net-zero emissions by 2030. For subsidiaries in the areas of waste management, recycling and renewable energy, which are under long-term operational control, a 15% reduction is set
for 2026 and net zero for 2050.
　

In 2022, ECOVE conducted comprehensive voluntary organizational greenhouse gas inventories across all Energy and Resources Centers under contract operation, setting 2022 as the base year and managing performance based on emissions intensity. The 2025 emissions intensity was 453 kg CO2/t, a decrease of approximately 0.88% from the baseline year (2022), primarily because the calculation methodology changed in 2025 from flue gas sampling to waste sampling.
