Establishment of the Net Zero Emission Project Promotion Team
The raging extreme weather has led to frequent global disasters. In the past three decades, countries have actively addressing climate change, with achieving net-zero emissions emerging as a key issue. Many countries are setting carbon reduction pathways and developing new technology. Taiwan also announced its target of net-zero carbon emission by 2050.
Although TWC generates minimal direct GHG emissions throughout the production and distribution process, abnormal rainfall often affects the stability of water supply. Therefore, the Company established the Zero Emission Project Promotion Team in 2022, with the president serving as the convener from 2023. The team was renamed “Net Zero Transition Team” in 2024, and it is composed of representatives from TWC’s 9 departments to conduct inventory of technology, equipment, etc. The Environmental Protection Agency’s reduction targets are referred to for the formulation of the net-zero emission targets and carbon reduction strategies, and regular review and promotion of them are also made to achieve the national net-zero emission policy.

Energy Use

According to statistics, the electricity consumption in 2023 was 1 billion kWh. The GHG emission in 2023 was 497,739,410 kgCO₂e, and the emission intensity was 0.156 kgCO₂e/M³.
To improve the energy use efficiency so as to effectively reduce power costs, all Branches and plants of TWC are asked to follow the TWC’s Key Points for Saving Power Costs and provide specific measures and review the implantation status.

Promotion of Green Energy

To cooperate with the government’s renewable energy promotion policy, TWC completed the installation of solar PV power generation equipment on the tops of 5 clean water ponds in 2018 first. In 2019, the Company continued to install such equipment on the roofs of 32 structures and 1 reservoir, which were completed in December, 2022. Solar PV power generation equipment was installed on the roofs of 17 structures in 2023.

Reducing Energy Consumption of Services

In response to the policy of energy conservation and carbon reduction, TWC has implemented e-billing services (e-bills, SMS bills). In addition to actively promoting e-bills (bills sent via emails), a “SMS bill service” was also launched from January, 2021, to allow the public to choose to apply for e-bills or SMS bills based on their own needs, making it more convenient to collect bills, read bills, and pay the water bills. The public can easily pay the water bills and get the bill information anytime, anywhere, reducing the use of paper and achieving environmental protection.
To encourage our customers to use of e-bills, we advocate it actively through print media, the website, publicity DM, Facebook, and paper bill envelopes. In addition, we also set up booths to publicize the e-bill business in the events held by local government agencies through our Branches. According to the Carbon Footprint Information Platform- Carbon Label Product Information in 2022, the use of every use of an e-bill can save 7.6g of carbon dioxide emissions calculated based on the carbon dioxide emissions. In 2023, 6,026,942 e-bills were sent to replace paper ones, reducing carbon dioxide emissions by 45,805 kgCO2e after conversion (6,026,942 e-bills * 7.6 g/1,000).
