Engineering a Bright Future for Enterprise

We recognize the value and importance of preserving the global environment, and our environmental management efforts are contributing to sustainable social development.

The SK E&C Environmental Management System(EMS) was established to fulfill corporate social responsibilities toward the environment and to ascertain fundamental environmental impact in advance of any projects. Internal regulations on the environment are much stricter than what the law allows.

Our EMS first obtained ISO 14001 certification in October 1997 and that certification was renewed in October 2008. In addition, we formed the Environment Management Committee to deliberate and decide on important issues pertaining to the environment as well as to provide regular assessments on overall environmental performance. In addition, the Green Culture, Green Process and Green Product Subcommittees operate under the Environment Management Committee, completing the foundation for environmental management and making SK E&C stand out as an environment-friendly company.

Advancing Together with PartnersVarious “win-win cooperation” programs are in place to promote growth and advancement with business partners. SK E&C organizes training programs every year to improve partners’ quality and raise their awareness of safety. The management support center offers them the know-how to build various management systems. SK E&C supports their development and commercialization of new technologies, and they accompany SK E&C to work on overseas projects. Such assistance in their overseas expansion is part of the win-win management policy.

Taking Customer Satisfaction to the Next LevelThe safety and health management program seeks to ensure stakeholder wellbeing through accident-free construction. The latest systems are applied, and resource competencies are being bolstered and integrated to maintain competitiveness. SK E&C operates integrated and complementary IT systems with business partners and works closely with them to strengthen ties. Meanwhile, a unique “culture of quality” is being built at SK E&C. To this end, process efficiency in the quality management program is improved steadily. The lessons learned from cases studies of success as well as failures are utilized as much as possible.

The SK Group is leading positive change to ensure all members of society can be happy.

Corporate Social ResponsibilityThe SK E&C Hope Maker CSR Program pairs all employees 600 children and adolescents from low-income families in the Seoul area to provide economic and moral support continuously. In addition to monthly economic assistance, employees meet with their counterparts regularly and visit their homes to provide vitally needed home improvements. They also help their counterparts develop their natural talents to become good citizens and even help to pay medical expenses in emergencies. In addition, the SK E&C Customer Centers around Korea have organized a program that improves the living environment of needy families since 2006. Each month, Center employees visit selected families to repaper walls, lay new linoleum, put down tiling and so on. The Customer Centers have received numerous plaques of appreciation from local communities as a result of this program.

Environmental & Safety EducationSK E&C runs various educational programs for children to raise their appreciation for the importance of safety and the environment. The Happy Green School program offers classes on the environment and experiential programs help the children to foster a love for nature from an early age and to acquire eco-friendly living habits. Systematic environmental education support is provided to primary school students in the greater Seoul Area. We are also leaders in the effort to instill safety awareness in children. Employees volunteer to act as crossing guards and to lead safety experiential activities for children who are attending primary schools near worksites.

Environmental Preservation ActivitiesSK E&C is offering nature’s blessings to customers while at the same time preserving the natural environment for all. SK E&C has adopted a 330m² section of Seoul Forest for regular care throughout the year (managing wetland plants, picking fruits, weeding, raking leaves and winterization), while worksites around the country take responsibility for regular cleanups of a local mountain and stream in the vicinity. In addition, the company-sponsored programs are being expanded to include environmental education, natural disaster relief support, and forestation projects. Four times a year, a Happiness Sharing with Families event is held, allowing employees and their family members to spend quality time while taking part in environmental protection activities together.

Global CSR Activities SK E&C continues to expand its scope of work at locations outside Korea, prompting the need for greater involvement in local communities. A regular effort is made to strengthen goodwill in communities near worksites as well as to cultivate the sensitivities of the local children. We donated 500 Arabic editions of books on Korean culture and provided school supplies and books on various subjects to the Dumai Primary School in Indonesia and a Korean school in Kuwait. We also sponsored a high school football tournament in Esmeraldas, Ecuador. SK E&C is reconstructing the oil refinery, and programs such as these to improve the company image in the eyes of the public.

Build a Dream, SK E&C

Our robust CSR program is in step with the SK Group’s “Happiness Maximization” philosophy. Currently, more than 6,000 or our employees at the Head Office, branch offices and construction sites now take part of this philosophy. The program focuses on four main areas: domestic social contributions, environmental and safety education, environmental preservation, and global social contributions. SK E&C is fulfilling corporate social responsibilities while providing opportunities for employees to share happiness with members of local communities.
