Chevron, through GS Caltex, has an established tradition of partnering with the communities where we work. In South Korea, this includes:

  • Helping underprivileged children relieve their psychological distress

GS Caltex established the GS Caltex Foundation in 2006. Each year, GS Caltex makes an annual contribution to the foundation to fund initiatives that promote culture and the arts, social welfare initiatives, and education projects. GS Caltex’s $90 million culture and arts center in Yeosu—completed in 2012—presents musical and other cultural events for the community.

In 2015, Chevron began a partnership with the Community Chest of Korea (CCK), Korea’s largest community-oriented charity organization. With Chevron’s support, the CCK educates children on safety, provides social welfare specialists in child care centers, and supplies safety packages that include fire extinguishers and first aid kits.


record of achievement

Caltex began operating in South Korea in the late 1960s, just as the country was developing its economic strength. Recognizing South Korea’s growing demand for petroleum products, Caltex entered a joint venture in 1967. The partners formed the Honam Oil Refinery Co. Ltd., which built the nation’s second refinery in Yeosu, at the southern edge of the Korean Peninsula. GS Caltex is one of the largest and oldest joint ventures in South Korea between a foreign company and a Korean company.

In addition to refinery expansions, GS Caltex extended its presence into the South Korean petrochemicals business.

GS Caltex also began operating a network of service stations, which quickly gained a substantial share of Korea’s automotive gasoline business.

GS Caltex stands out for its high business standards and contributions to the country’s economy. Honors include the following: 

  • Order of Industrial Service Merit, Gold Tower (2014), from the government of the Republic of Korea 
  • Presidential Prize in the Mecenat Awards (2013), from the Korea Mecenat Association, for building and operating Yeulmaru, the culture and arts complex in Yeosu
