Daewoo Engineering & Construction (Daewoo E&C) announced on the 15th that its independently developed “carbon-reducing early-strength concrete” has passed the second-stage review for Carbon Reduction Certification by the Korea Chamber of Commerce and Industry, and that the company is now moving to secure carbon credits. Application of 300,000㎥ of this concrete is expected to reduce greenhouse gas emissions by approximately 32,000 tons.

The Carbon Reduction Certification is a system operated by the Korea Chamber of Commerce and Industry that verifies greenhouse gas reduction effects and issues carbon credits through a three-step review process: methodology certification, project design document (PDD) certification, and monitoring report certification.

Daewoo E&C has been pursuing certification for “DECOCON,” a carbon-reducing early-strength concrete jointly developed with Halla Cement. The product has now passed the review up to the second stage, and the company plans to obtain carbon credits after undergoing monitoring report certification, which verifies actual reduction performance.

The certification process utilized quality and construction data accumulated from Daewoo E&C’s actual construction sites. With consulting support from Hanyang University’s Carbon Neutral Smart Architecture Center, the company calculated the greenhouse gas reduction effect based on on-site data.

According to Daewoo E&C, the expected carbon reduction from applying 300,000㎥ of carbon-reducing early-strength concrete at construction sites is approximately 32,000 tons. Once carbon credits are secured, the company is considering using them in the voluntary carbon market or to voluntarily offset greenhouse gas emissions generated at overseas project sites.

Previously, Daewoo E&C obtained Environmental Product Declaration (EPD) certification and low-carbon product certification from the Ministry of Climate, Energy and Environment for this concrete. Through the current Carbon Reduction Certification process, the company is now moving beyond environmental performance evaluation of the product to securing credits for its actual greenhouse gas reduction performance.

A Daewoo E&C official stated, “Passing the methodology certification and project design document certification, which are the core procedures of the Carbon Reduction Certification, is highly significant in that we have cleared an important step toward objectively verifying the greenhouse gas reduction effects of our carbon-reducing technology,” adding, “We will swiftly complete the remaining monitoring report review to become the first Korean construction company to secure carbon credits for in-situ cast concrete, and actively utilize them in implementing carbon neutrality.”
