  Achieving net zero emissions by 2050 is the objective of Taiwan and most countries in the world. Water Resources Agency (WRA) is actively participating in net zero transformation, and formulated specific carbon reduction objectives for each year based on the average total carbon emissions from 2019 to 2021. The goal is to achieve long-term carbon neutrality by 2050 through the reduction of engineering carbon emission, increase of tree planting for carbon sequestration and green energy.

Carbon reduction objectives for each year of WRA


  In response to the 2050 net zero emissions objective, Water Resources Agency has proposed the following three major responsive measures:

  1. Carbon reduction of hydraulic engineering to head towards carbon neutrality:
    Develop carbon reduction strategies for each stage of the engineering life cycle (planning, design, construction, and operation), including low-carbon construction methods, carbon reduction designs, the use of green and recycled materials, improvement of construction specifications, and environmental carbon sequestration. Precisely implement total carbon emissions control and work towards the goal of carbon neutrality by 2050.

  1. Strengthening land afforestation to increase carbon sequestration effectiveness:
    By integrating ongoing projects such as “Greening and beautifying environment construction”, “Prevention and control of riverbed dust” and “Encouragement for private sectors to afforest on state-owned land”, the planting capacity will continue to be enhanced in 2023, and the planting area is expected to increase by 159 hectares. In addition to benefiting the environmental greening and beautifying, it also enhances the carbon sink. Three sites are selected for the application to the Environmental Protection Administration for the offset program registration of "Afforestation and Reforestation", including "Tonquze River landscaping field", "Beiyuan Park of Shimen Reservoir", and "Zhongzhuang Retention Basin Park”.

  1. Reservoir hydropower to support green energy network:
    WRA refine the delicate high water level operations in reservoirs, review water-saving dispatch measures on a rolling basis depending on water conditions, and adjust power generation without wasting water resources to support the green energy power supply network. Through continuing to collaborate with Taiwan Water Corporation to develop water-based photovoltaic systems, including 5 reservoir sites (Jiji Weir, Hushan Reservoir (2 sites), Niaozuitan Artificial Lake, Zengwen Reservoir) and 4 regional drainage sites (Desheng River, Houzhuang, Beishi River, Cieding Seaside Park), it is expected to increase the installed capacity by around 31.4 MW during 2023~2025. WRA also cooperates with Taiwan Power Company, Taiwan Water Corporation, and private sectors to promote small hydropower systems to increase power generation capacity. So far a total of 20 sites have been promoted, which are expected to generate an additional 22.8 MW during 2023~2025 in order to achieve the optimal synergy of energy saving, green power, and carbon reduction.

  1. Achievement:
    In the 111th fiscal year, 14 branches of Water Resources Agency totally conducted 170 construction projects, including 107 river and sea-related projects, 27 water resource projects, 26 dredging projects, and 10 tetrapod-related projects. The cumulative carbon reduction amounted to 68,389 tCO2e, achieving a reduction rate of 20.39%. Furthermore, The proportion of green funds reached 18.2%. Additionally, 148,100 trees and 1,379,900 shrubs were planted, covering an area of 178.49 hectares. These efforts successfully met the goal of a 20% reduction set for 2022.
