Korean Chemical Industry Statistics

With Korean chemical sector exports hitting 89.5 billion USD in 2022, up 12.4% from the year before, this page pairs the boom in global shipments with the less expected side of the ledger, including an 8.5% cut in CO2 emissions to 45 million tons and renewable energy rising to 12% at chemical plants. You will also see where the capacity, people, and innovation move together, from 285,000 workers and 5.2 trillion KRW in chemicals R&D to 12,500 patents filed and 78% recycling of chemical waste.
