OVERVIEW OF GREENHOUSE GAS EMISSIONSGHG Emissions Overview

Hsin Tung Yang's total carbon emissions in 2019 were 7,676.5 ton CO₂e. This includes GHG emissions from power consumption at Dayuan Plant and the headquarters building. In terms of Dayuan Plant, most of its GHG emissions were carbon dioxide (CO₂), methane (CH₄) and perfluorinated chemicals (HFCs). Scope I direct emissions in 2019 were 360 tons of CO₂e and most of which was generated from liquefied petroleum gas (LPG), accounting for 55% and followed by diesel at approximately 19%. The rest of which were fugitive emissions from sources including coolant from air conditioners. Scope II indirect emissions were approximately 7,304 tons CO₂e, in which power utilization from production processes accounted for 55.5% of all emissions and the rest of which was from externally procured steam, at around 37.3%. Compared with 2016, carbon emissions at Dayuan Plant have been reduced by 8% in 2019. Additionally, in terms of emission intensity, the 2019 GHG emission intensity at Dayuan Plant was 8.92 (tons CO₂e/NT$1 million), which indicated a 6% decrease from that of 2016.
(Note: 2019 GHG emissions data have not been verified by a third-party agent, and the data from headquarters are only calculated based on electricity bills)

Formulating a GHG Inventories Team

Hsin Tung Yang began conducting greenhouse gas (GHG) inventories in 2017, and a GHG Inventories Team was established for this means. Inventories on all greenhouse gases generated within the boundaries of Dayuan Plant's operations were taken based on ISO 14064-1 standards, and 2016 was set as a base year. We complete total inventories of Dayuan Plant's emissions before July in each year based on the GHG management procedures stipulated in ISO 14064-1 standard and our own operating procedures enacted based on internal assurance protocols. In the future, our headquarters building will also be included in the GHG inventories. In addition, since power consumption accounted for 55.5% of all emission sources, we have implemented annual energy-saving and carbon reduction programs in line with ISO 50001.

Participating in Joint Carbon Reduction Plan from Taoyuan and Kaohsiung International Airports

Hsin Tung Yang's stores at Taoyuan Airport and Kaohsiung International Airport have voluntarily joined "Taoyuan International Airport Joint Carbon Reduction Plan" and "Kaohsiung International Airport Joint Carbon Reduction Plan" in 2018 and 2019 respectively. We have set up dedicated energy management units and management personnel, as well as annual power-saving goals and carbon reduction goals. Besides monitoring power utilization in each month, we have also opted for voluntary carbon reduction measures. On top of estimating GHG emissions through calculating externally-procured electricity and coolant, oil consumption, waste and transportation activities to/from the airports, we have also achieved outstanding energy-saving and carbon reduction results. Our power consumption from June to September 2018 was reduced by 2.3% YoY, and received No. 3 in power and energy conservation and carbon reductions award from Taoyuan International Airport in 2019.

MANAGEMENT MEASURESManagement Measures

In terms of Dayuan Plant, energy-saving goals are achieved by establishing energy management system, replacing lighting equipment and by implementing annual energy-saving processes and equipment, as well as by installing solar panels to generate energies. For our channels, we have infused energy-saving and carbon reduction thinking into the architectural design of service area buildings and public space. Besides improving air conditioning and lighting, we have also targeted heat sources at external heat insulation and internal dining areas as well as established a renewable energy system, thereby promoting energy conservation on top of creating brand-new looks for the highway service areas.

Building an energy management system

1. Dayuan Plant: we established an Energy Management Committee and achieved ISO 50001:2011 Energy Management System certification, as well as implemented energy inventories system, documented monitoring, and calculated energy consumption to create an electricity and heat balance chart in order to understand and analyze the energy efficiency of major energy-consuming equipment

Improving indoors lighting and air conditioning

1. Dayuan Plant: air conditioning, lighting, and pump facilities were improved.
2. Highway service areas and airport shops: LED lighting and energy-saving light bulbs were adopted in line with natural light. Energy-saving air conditioners with higher EER value were used, and the hours of using the air conditioners were adjusted based on the size of the area and number of persons
3. Headquarters: we adopted energy-saving lights and LED lights and fully utilized the available natural light to reduce artificial lighting. Temperature of air conditioners is also appropriately adjusted.

Outdoors heat insulation

1. Highway service areas: we reduced solar radiation heat by putting up glass heat insulation films and installing shading panels and blinds, thereby maintaining the indoor environment at a comfortable level.

Treating heat sources at dining area

1. Highway service areas:Food retail counters are grouped together and heat sources are properly collected through heat ventilation system. Heat is collectively discharged via ventilation fans and ventilation tubes, and external fresh air is adequately inducted to reduce air conditioning in the service area halls from escaping and impacting the cooling effect of the air conditioners.
2. Hot and prepared foods at the convenience stores are heated via electrical means whenever possible to reduce heat sources and environmental impacts.

Installing renewable energy

1. Dayuan Plant: installed solar power generation system in line with the government's green energy policy.
2. Highway service areas: installed power generation systems including solar tracker system and wind turbines to not only generate power in an environmentally-friendly manner, but also allows road users to get to know renewable energies.

Advocating for energy conservation

1. Highway service areas and airport shops: we advocated energy conservation to all retail counters and employees, and put up slogans for energy conservation.
2. Headquarters: promoted energy conservation and turning off lights at sparsely used/vacant areas.

Clean Production Energy-saving Measures at Dayuan Plant

For the past four years, Dayuan Plant has achieved significant clean production results through promoting energy-saving improvement measures. Consumption of major energy sources did not increase with enhanced productivity, but rather, a year-by-year reduction trend has been achieved. To achieve our 1% annual energy conservation goal, annual energy conservation action plans are proposed and progress of implementation is also reported at the energy management review conference in each year. Key targets have included buildings (replacing lights, cooling tower), processes (air conditioning, cooling water pump, evaporative condenser, air compressor, steam cookers and meat floss fryers).
