SK Eco Plant has received the top rating in the co-prosperity index evaluation for 10 consecutive years.

The company announced Wednesday that it achieved the highest rating in the "2026 Co-prosperity Index Rating Evaluation (based on 2025 earnings)" released by the Korea Commission for Corporate Partnership. SK Eco Plant first earned the top rating in 2015 and has maintained it every year from 2017 through this year, a streak of 10 consecutive years.

The co-prosperity index is a system that comprehensively assesses companies' mutual-growth cooperation activities and their compliance with fair-trade agreements. It combines evaluations by the Korea Commission for Corporate Partnership and the Korea Fair Trade Commission to assign one of five ratings: excellent, good, average, poor and very poor.

SK Eco Plant has embedded the Korea Fair Trade Commission's four key compliance practices — partner selection and registration, contract execution, document issuance and retention, and internal review committee operation — into its internal regulations and operational guidelines. The company also conducts regular audits of fair-trade compliance across ongoing projects.

Support programs for partner companies continue as well. Through a co-prosperity loan fund, environmental, social and governance (ESG) diagnostics and consulting, and fair-trade education, the company helps partners stabilize their operations and strengthen their capabilities.

SK Eco Plant is also expanding collaboration with mid-sized companies, small and medium-sized enterprises and startups that hold innovative technologies. Through programs such as "Tech Open Collaboration" and "ConTech Meetup Day," the company identifies firms in future technology sectors including semiconductors and AI, and supports joint research and development as well as technology commercialization.

"Achieving the top rating for 10 consecutive years is the result of consistently practicing fair trade and mutual growth built on trust with our business partners," said Jeong Tae-su, SK Eco Plant's chief procurement officer. "We will continue to communicate closely with our business partners and strengthen practical support and cooperation to further solidify a sustainable foundation for mutual growth."

Meanwhile, SK Eco Plant has launched a "one employee, one AI agent" system that analyzes each employee's work data to develop and deploy AI agents tailored to their specific roles. The company plans to identify work patterns and bottlenecks for each employee based on actual job data, and apply customized AI transformation solutions by organization and job function.
