Nationwide mobile carrier KT said Friday that it has joined the carbon management global leaders’ club of a U.K.-based nonprofit organization.

The Carbon Disclosure Project selects the best companies at carbon management each year by assessing factors related to climate change response such as corporate structure, strategy, carbon emissions accounting and communications. CDP Korea selected the top five companies among the 250 largest Korean enterprises in terms of market capitalization this year.

KT topped the list in the area of communications, receiving a perfect score of 100 in the Carbon Disclosure Leadership Index.

KT said it had run an environment management committee since 2009, comprehensively covering five areas of energy saving, green purchase, green technology development and environment strategy.

The company also said it had built eco-friendly IT-based ecosystems such as an all-IP network, cloud communication center, green IDC, and smart working system in a bid to reduce carbon emissions.

“Environment management is one of our important strategies to become a green ICT convergence leader,” said Kim Eun-hye, KT’s executive vice president of communications. “We will not be complacent about this but continue to improve our green management system down the road.”

CDP is a global project sharing management information related to climate change issues and responses from key listed companies around the world. It publishes an investment guideline report every September for financial organizations worldwide.
