Greenhouse Gas Emission Reduction Program

     National Chiayi University (NCYU) implements a comprehensive Greenhouse Gas (GHG) Emission Reduction Program, formally approved and overseen by the Energy Conservation and Carbon Reduction Committee.   The program covers all three scopes of emissions—Scope 1 (direct fuel and equipment emissions), Scope 2 (purchased electricity), and Scope 3 (transportation, waste, and supply-chain activities)—and follows an annual monitoring and reporting framework consistent with ISO 14064-1.

• Scope 1 Reduction: NCYU has converted campus boilers to solar-assisted systems, replaced official vehicles with electric ones, and integrated hydrogen fuel-cell demonstrations. Refrigerant management and maintenance are performed under documented procedures to minimize direct GHG leakage.

• Scope 2 Reduction: Electricity-related emissions are reduced through the operation of solar PV, wind, hydrogen, and biomass systems generating 4,270,551 kWh (17.25 % of total consumption), and through campus-wide ISO 50001 Energy Management and smart EMS controls.

• Scope 3 Reduction: The university promotes zero-emission transportation, comprehensive waste-resource recycling, and intelligent water-management systems that lower indirect energy use. Student and staff commuting emissions are further reduced by e-buses and YouBike sharing programs.

•   GHG Inventory and Reporting: Each year, NCYU conducts a carbon-inventory audit using the Ministry of Environment GHG Inventory Platform, records emission data from each campus, and evaluates reduction outcomes.  The platform’s dashboard interface provides detailed visual summaries of each campus’s Scope 1–3 emissions, supporting data-driven management and public disclosure.  Results are reviewed by the Committee and disclosed in the Sustainability Report.

     These coordinated programs target all GHG scopes and integrate renewable energy, energy efficiency, sustainable transport, and waste management measures. They align with SDG 7 (Affordable and Clean Energy), SDG 11 (Sustainable Cities and Communities), and SDG 13 (Climate Action), supporting NCYU’s 2050 Net-Zero Campus Goal through continuous monitoring and improvement.

•  Program scope: Covers Scopes 1, 2 and 3, verified under the ISO 14064-1 GHG Inventory Methodology.

•  Monitoring body: Energy Conservation and Carbon Reduction Committee.

• Annual GHG Inventory: Conducted internally since 2023 using a licensed carbon management platform; will be officially integrated into the Ministry of Environment’s GHG Inventory System once it is launched in 2025.
