Welcome to Sustainable Development of Taiwan Sugar Corporation-Energy Conservation and Carbon & Waste Reduction

In order to effectively implement energy conservation and carbon reduction policies and to continue to promote energy conservation movement. In 2020, the results in electricity and energy saving (including fixed and mobile sources) in all units were converted to a total of 20,033.54MJ, reducing approximately 1,735 tonnes of CO2e.

Business unit	Energy saving measures and effectiveness
Agriculture Business Division	The old A/C equipment for flower forcing in Puli Farm was replaced with new ones, saving approximately 191 thousand kWh. The water walls for the greenhouse in Nanjing Farm were renovated (8 buildings), saving approximately 26 thousand kWh. The water walls for the greenhouse in Wushulin Recreation Farm were renovated (8 buildings), saving approximately 19 thousand kWh. The purchase of A/C heat pump equipment for the fourth greenhouse in Taitung Farm saved diesel consumption by 46,000 liters. The old air conditioners in the dormitory were replaced with new ones, saving about 5 thousand kWh.
Petroleum Business Division	All the lighting equipment in the 73 gas stations of the Petroleum Business Division was replaced by LED lamps. The total electricity consumption in 2020 was 2,812 thousand kWh, a decrease of 111 thousand kWh compared with the 2,923 thousand kWh in 2019.
Leisure Business Division	Solar power generation: Evergreen Plaza Hotel generated 61 thousand kWh of electricity while the canteen in Meet Gold Club generated 28 thousand kWh of electricity, reducing 89 thousand kWh of purchased electricity in total.
Sugar Business Division	Cleaning the energy-saving equipment of furnace (ECO, GAH), saving 274 m3 of fuel oil. Solar power generation in all factories, reducing purchased electricity by 203 thousand kWh.
Biotechnology Business Division	The capacity of the solar power generation equipment (rooftop type and ground type) is 1,670 kwp, generating 2,253 thousand kWh of electricity in 2020. Replaced lamps with LED ones for energy saving: old lamps (114W) in the packaging area (50 sets) and production area (50 sets) were replaced with LED lighting (44W), saving 2,000 hours* (114W-44W)/ 1,000* (100 sets)* power saving rate of 0.5 = 1,000 kWh of electricity. Replaced A/C equipment for energy saving: Old A/C equipment consumed 883 kW of electricity annually and the 25 air conditioners in the dorms were with replaced with the ones with CSPF at 5.93 and annual electricity consumption of 562kW, saving (883kW-562kW)(25 units) power saving rate of 0.4=3,210 kWh.
Environmental Protection Business Operation Center	Replaced the original 40W fluorescent lamps with 40W LED lamps, saving 41,700 kWh of energy. Replaced the air condenser motor, saving 65,100 kWh of energy. Lighting equipment was replaced with new ones, saving 78,390 kWh of energy. Recovered cooling water (renewal of the main condensate pump), saving 95,400 kWh of energy. Reduced the times of furnace tube breakages, saving 131.9 m3 of diesel fuel. Improved the production efficiency and energy saving (renewal of furnace tube), saving 79,350 kWh of energy.
Yunchia Operation Branch	Replaced the A/C equipment with new ones on the 1st and 2nd floor of the office building (replaced the 21 window-type A/C with the split DC Inverter AC). Replaced the total 240 T8 lighting lamps in the office building with LED lamps, which can save approximately 21,600 kWh annually.

Greenhouse Gas Inventory

In 2020, the overall GHG emission was 466,910 tonnes of CO2e, a 21.67% decrease compared with 2019. The GHG emission intensity was 0.018 tonnes of CO2e/NTD thousand of revenue, 21.74% lower than 2019. The main reason for the reduction was mainly because the operations of the Gangshan and Kanting Incineration Plants became stable, reducing the consumption of fuel oil and purchased electricity, and the GHG emissions also decreased, leading to the reduced intensity of GHG emission. The total GHG emission amount and emission intensity of TSC and its affiliations is shown below.

Green Meetings

TSC continues to promote the use of video conference to replace physical meetings not only to reduce time and cost for longdistance travel and to increase work efficiency, but also to achieve the benefits of energy conservation and carbon reduction. Based on the assumption of “one person/ per business division”, there were a total of 465 video conferences held in 2020, and the calculated traveling distance saved (round-trip) was 446,420 km; in addition, according to the EPA’s carbon footprint calculation service platform, the carbon footprint coefficient of a small passenger car (petrol) was 0.115 KgCO2e/passenger-kilometer (the GHG emission generated from the small passenger cars used for carrying passengers, including emissions from the fuel production, distribution and vehicle consumption) was reduced by 51,338 KgCO2e.
