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 2021, the results in electricity and energy saving (including fixed and mobile sources) in all units were converted to a total of 23,294.78 GJ, reducing approximately 2,094.36 tonnes of CO2e.

Greenhouse Gas Inventory

          The company has been dedicated to carbon reduction for years. In 2021, our Xiaogang Sugar Refinery of the Sugar Business Division passed the external verification of ISO 14064-1 GHG Inventory. TSC’s overall GHG emissions in 2021 was 482,202.79 tonnes of CO2e, an increase of 3.28% compared with 2020. The GHG emission intensity was 0.018 tonne of CO2e/thousand of revenue, remaining flat compared with 2020. This was mainly because of the increase in the overall revenue of the entire company and the equipment renovation in the Environmental Protection Business Operation Center, resulting in the increase in purchased electricity, leading to increased GHG emissions and the same emission intensity. The total GHG emission intensity of TSC 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 712 video conferences held in 2021, and the calculated traveling distance saved (round-trip) was 494,122 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 56,824 KgCO2e.
