• Energy consumption and GHG management

    Energy consumption

    There are two types of energies that Tatung consumes – direct energy and indirect energy. Direct energy sources are from diesel fuel oil, LPG, and diesel. Indirect energy source is purchased electricity from Taiwan Power Company. The most consumed energy in 2017 was purchased electricity and the amount was 216,152.20 GJ(90.68%)which equaled to 60,042.28 kkw-hr; followed by LPG with 12,753.06 GJ(5.35%)which equaled to 252.69 tons. The total amount of energy consumption in 2017 was 484.53 GJ more than in 2016, which was 0.2% increasing.

    Greenhouse gas emission

    Greenhouse gas emitted by human activities have already caused global warming and led to the threat on the sustainable development. Corporations actively to reduce the greenhouse gas emissions are not only to show a responsible image to the public but also able to reduce the operation costs from running the business. In order to investigate the amount of GHG emission thoroughly and comply with the regulation, Tatung actively implements ISO14064-1 greenhouse gas management system into the factories. So far, San-Hsia Factory, Taoyuan Wires and Cables Plant, and Taoyuan 1st Plant carry out GHG inventory and get verified by third parties based on reasonable level of assurance. For the purpose of enhancing the ability to do greenhouse gas inventory in the factories, Tatung runs ISO14064-1 Internal Verification Class every year. We are expecting to have more well-trained employees through these classes and they are able to do the greenhouse gas inventory well and pass the verification by the third party in the future.

    ▲ Tatung GHG inventory and verification status

    The total GHG emission amount in 2017 was 33,276.02 tons CO2e which was 135.08 tons CO2e(0.41%)more than in 2016. The largest emission source was purchased electricity(scope 2)which took 95.45%. The second largest portion was LPG which only took 2.42%.

    Energy saving and GHG reduction

    Global warming greatly increases the frequency of extreme weather events and directly causes impacts to the operation of a business. In order to fulfill corporate social responsibility and reduce operating costs, Tatung sets short and medium term goals which are based on energy intensity per product and the baseline year is 2013.

    The goals are:
    Short term – reduce 3% in 2016,
    Medium term–reduce 6% in 2018.

    To achieve the goals, Tatung implements ISO 50001 Energy Management System in the factories to sharpen up company's energy performance. So far San-Hsia Factory, Tayuan Plant, and Taoyuan Wires and Cables Plant have established ISO 50001 and passed certification.

    ▲ Tayuan Plant ISO 50001 certificate

    In addition, we conduct annual energy audit and report the energy consumption information to the government as well as implements energy saving projects in H.Q. and the factories. In 2017, Tatung reduced about 2.35 million kwh of purchased electricity consumption via 4 dimensions which equaled to 1,241 tons of GHG emission reduction(3.2 Daan Forest Park's carbon reduction amount).

    Note:One Daan Forest Park can absorb 389 tons of GHG every year.

    In 2017, there were 5 major products achieving the goal of 4.5% reduction in energy intensity. The completion rate was 55.56%. The main reasons for those failed to achieve the goal were producing large size products which increased power consumption; the product testing time and method were more strict than previous years due to customer's quality requirements, and the factory added RTO air pollution treatment facility so the fuel consumption was increased.

    For the major products failed to achieve energy intensity goal, we will replace the old energy-using equipment. For example, Taoyuan 1st Plant plans to replace one 100HP traditional air compressor with a high energy efficiency air compressor with inverter. Taoyuan Wires and Cables Plant plans to replace one old production equipment with a high energy efficiency production equipment, and Tayuan Plant plans to replace on diesel fuel oil drying furnace to LPG drying furnace and install the automatic power breaker for the power consumption equipments above 5HP. In addition, we will introduce an external professional team this year to conduct energy-saving counseling, assist in the efficiency diagnosis of the in-plant equipments, establish baseline, engineering planning, and performance verification in order to improve production efficiency and reduce energy use. Each division will conduct the second phase of the project, "Significant Energy Equipment Monitoring and Management" to reduce energy consumption. The energy conservation team(formed by H.Q. and the plants energy managers)will also conduct the power consumption monitoring area(SEU)monitoring plan by using power analysis equipment to establish a historical database of electricity consumption in order to identify the future energy-saving potentials.
