What Problems Does This Solve
Adopting PLC (Portland Limestone Cement, low-carbon concrete) helps solve the carbon emission problems that the construction industry has long faced. Traditional cement manufacturing processes are highly energy-intensive and generate large carbon emissions, making them one of the main sources of global greenhouse gas emissions. PLC partially replaces clinker components in its formulation, reducing carbon dioxide generated from limestone decomposition during cement manufacturing, significantly lowering overall carbon footprint. Meanwhile, PLC maintains the same construction performance and structural strength as traditional concrete, enabling widespread application in various engineering construction projects. Its application not only reduces carbon emissions but also improves resource utilization efficiency, responding to corporate net-zero transformation and international sustainability goals. Through introducing PLC, construction industry players can effectively manage environmental impact while ensuring engineering quality, achieving the dual goals of environmental protection and operational performance. Kedge Construction’s active adoption of low-carbon building materials is a concrete practice of source carbon reduction and promoting green construction methods.
Our Actions
To accelerate low-carbon transformation, Kedge Construction has taken the lead in promoting the introduction of PLC (Low-Carbon Concrete) and demonstrated concrete action capability. In 2024, we commissioned the Taiwan Construction Research Institute and the Department of Civil Engineering at National Cheng Kung University to complete PLC seismic testing at the National Center for Research on Earthquake Engineering, verifying its structural safety. On June 24, we held a symposium to publicly share research results and promote industry exchange. Kedge also pioneered the introduction of PLC in actual engineering projects, becoming the first construction company nationwide to apply it in high-tech facilities (ASML) and public works (Chiayi C611 Railway Elevation Project), demonstrating implementation capability and industry leadership. Additionally, we actively participate in the “Taiwan Cement Low-Carbon Construction Pioneer Alliance,” working with industry, government, and academia to promote the widespread adoption of sustainable building materials. From research and verification to practical application and industry integration, Kedge implements carbon reduction through action, laying a solid foundation for the construction industry to move toward net-zero goals.
Highlights and Special Features
Kedge collaborates with parent company Kindom Development to adopt PLC comprehensively in all new development projects starting from 2025, demonstrating the group’s determination to promote low-carbon transformation. Eight development projects are expected to use more than 640,000 cubic meters of concrete, with estimated carbon reduction benefits of 75,000 tons CO2e and a carbon emission reduction of 34%. This action not only expands the practical application of low-carbon building materials but also integrates upstream and downstream resources within the group, driving supply chain transformation and establishing a substantial demonstration and cooperation model for Taiwan’s construction industry in using PLC, advancing comprehensively toward sustainable construction.
Estimated Carbon Reduction Benefits
- Carbon emissions reduced by 34%
- Carbon reduction benefits reaching 75,000 metric tons CO2e
