SK C&C Issues Voluntary Carbon Offsets on Blockchain-Based Credit Platform
SK C&C, the information communications technology arm of South Korean conglomerate SK Group, said last Thursday that it has issued a total of 186,595 carbon offset credits through 19 projects on the blockchain-based carbon reduction certification and credit trading platform Centero.
Amidst the ever-growing challenge of climate change, industries and companies around the world are attempting to reduce their carbon output and reach net zero emissions through involvement in carbon finance — specifically, carbon credit markets.

Understanding carbon markets
There are two types of carbon markets — the compliance market, which uses a cap-and-trade system, consists of governments and companies that are legally mandated to offset their carbon emissions. On the other hand, the voluntary carbon market (VCM) operates outside of mandatory frameworks and uses a project-based system to allow companies, organizations, and individuals to trade carbon offset credits voluntarily. Each of these carbon offset credits represents the reduction of one metric tonne of carbon dioxide or greenhouse gas (GHG) emissions. Participants in the voluntary market are mainly driven by their corporate social responsibilities, shareholder pressure, or PR motives.
Revolutionizing voluntary carbon reduction
Centero — short for Center of Net Zero — provides a one-stop registry service that enables monitoring, reporting, and verification of greenhouse gas reduction projects in the VCM, and issues certified carbon reduction credits to support credit transactions with companies that are pursuing net zero goals. It was developed by SK C&C and is currently operated by the KCCI Center for Carbon Reduction Certification according to the KCCI Carbon Standard, which evaluates and certifies carbon reduction efforts.
Centero takes care of the entire process of voluntary carbon reduction projects, from preparation to registration and execution, credit certification, and credit distribution. Its advantage also lies in its transparent management of carbon reduction projects and resources that reflect global regulations and standards, from organizing project information to keeping records of carbon reduction credits. Companies can also buy and sell credits on Centero’s intermediary carbon credit marketplace.
Voluntary carbon reduction projects span a vast range of industries, from manufacturing and chemicals to information technology (IT) and construction. Current ongoing projects include carbon capture and waste management initiatives.
Notably, Centero manages all credit information and transactions using blockchain technology. It makes all relevant information accessible to companies — including information about certifiers, verification, and quantity of issued credits — thereby increasing security and transparency in transactions. Credit-related events, such as the transfer of ownership, are also managed through blockchain processes.
Through its most recent achievement, Centero has demonstrated a total carbon reduction effect of 186,595 tonnes.
“The mandatory market has limited corporate participation, resulting in insufficient trading volume and difficulties in handling the demand for carbon emission rights due to the strengthening of global GHG emission regulations. Through Centero, we will encourage participation from local companies and organizations in voluntary carbon reduction projects and help accelerate a privately-led voluntary carbon market,” said Bang Soo-in, Head of SK C&C’s Digital ESG Group.
