Environmental Management

We create a sustainable future where people, society and the environment will coexist.


SK ecoplant has established and implemented environmental management policies in line with the direction of our projects, which aim to create a sustainable future where people, society and the environment coexist in harmony. Promoted under the direction of the CEO, environmental management is carried out by the Quality Environment Division, which is charged with company-wide environmental management, to enhance efficiency. Plans for environmental management are reported annually to the Board of Directors, which is chaired by the CEO, and the inclusion of improvements to environmental performance in executives’ performance assessments was reported to the BOD in 2022.
Starting in 2022, KPIs for improving GHG emissions, water intake, the amount of waste generated, and energy consumption were granted not only to the division in charge of environmental management, but also to each business unit. In order to systematically promote environmental management across our businesses, SK ecoplant has set up clear environmental goals and established environmental guidelines that encompass a wide range of areas, including environmental management systems, construction site and business facilities, products and services, distribution and logistics, waste management, eco-friendly supply chain, and due diligence and M&A. In addition, having recognized the impact of the construction industry on biodiversity, we have set up policies to minimize the adverse impact of our business. The parent company and our subsidiaries conduct business in accordance with our environmental management policies, and we recommend our customers and suppliers to follow suit. In order to avoid complacency, and to receive international recognition, we have been certified to ISO 14001 and strive to maintain this certification. To comply with on-site environmental regulations and build eco-friendly construction sites, SK ecoplant establishes environmental assessment plans on a yearly basis, and conducts on-site environmental audits at about 90 domestic business sites every month. Based on an environmental audit checklist composed of 54 items, business sites – as well as their systems and physical status – are regularly inspected to identify any non-conformities to environmental management, and so follow-up measures can be implemented.
At our construction sites, SK ecoplant carries out initial environmental assessments, inspections on regular environmental support, and theme-specific environmental assessments. The ESG Patrol program is used at our subsidiaries to conduct standardization and diagnosis of the environmental management checklist. Further, we respond to environmental examinations of our business sites that are subject to environmental impact assessment by government agencies, and implement improvements as necessary.

01. Environmental Audit

Environmental audits are conducted on a regular or random basis to prevent risks and enhance operational efficiency. In the first half of 2021, all our business sites were inspected without prior notice, and in the second half, all sites were divided into 4 areas (western, middle, eastern and southern) and examined based on project licensing and the 54-item checklist. As a result, we made improvements in 24 environmental risks discovered through inspection of scattered dust in the first half of 2022, making 100% corrections at each site on issues identified during the audits and providing continuous site management. In 2022, we are planning to improve the management efficiency of the on-site work environment by addressing each BU’s vulnerabilities to environmental management, thus promoting a wide range of activities such as on-site risk pre-assessments, re-establishment of special joint inspections and the environmental management e-guide, environmental impact simulations, and establishment of the Operation Platform System for a smart environment.

02. Violation of Environmental Regulations

Since our foundation, SK ecoplant has committed zero violations of environmental regulations. We have developed a project checklist for the entire lifecycle, including criteria such as the atmosphere, waste, noise and vibration, and water quality, as well as internally checking items such as project licensing, operation, prevention, and measures taken in terms of suppression facilities. In addition, we have developed a standard management model to directly check on-site environmental issues. Moreover, we have defined 6 non-conformance criteria for our major processes and used them to conduct an unscheduled site-wide inspection as part of our efforts to comply with environmental regulations.

* A penalty of KRW 10 million or more

03. Waste Management

SK ecoplant has recycled more than 90% of our waste generated in the past 3 years, and achieved a waste recycling rate of 99% in 2021 – exceeding our initial goal of 97.6%. We are resolving inadequacy in waste separation, sorting and storage, an issue frequently pointed out in regular environmental audits, is resolved across all sites. We are reducing waste by developing various plans for each construction phase, such as reusing and self-disposing on-site waste, discovering free recycling companies, minimizing the generation of construction byproducts, and utilizing eco-friendly construction engineering. Furthermore, we have established an efficient construction waste treatment process to identify the amount of construction waste generated, types of waste and recycling details across all sites in order to continue discovering more effective plans for a fundamental reduction of construction waste generated. Further, we continuously promote a variety of activities such as the recycling of packaging materials used for the delivery of fuel cell equipment, implementation of a free waste collection process, and production of woodchips from discarded trees.

04. Scattered Dust Management

Starting with the voluntary agreement signed with the Ministry of Environment for reduction of scattered dust in 2016, SK ecoplant has been dealing with high-density fine dust and improving air quality. In terms of processes that generate scattered dust across worksites, we are applying various reduction measures such as the adjustment of construction time, restricted use of outdated construction machinery, and dispatch of environmental management personnel while reporting our performance to the ministry. Further, we are monitoring the concentration of pollution sources at construction sites in real time and operating reduction facilities through an environmental IoT platform.

05. Noise Management

SK ecoplant is making efforts to discover optimal alternatives by proactively conducting simulations of environmental impact expected during construction. Noise simulation is conducted in line with a list of noise criteria that account for more than 80% of total environmental issues at construction sites. Through these simulations, we develop optimal alternatives such as changes of facilities, equipment, and construction engineering, which, in turn, help us minimize environmental risks and create tranquil surroundings for our construction sites.

06. Soil Management

SK ecoplant stands fully ready to prevent potential environmental damage on the ecosystem and local communities by designing, planning, and implementing measures against environmental pollution through preliminary inspections of soil risk at construction sites. In 2022, we plan to improve on-site environmental management information systems by including EMIS enhancement in the KPIs of our quality and environment organization.

07. Environmental Education

SK ecoplant’s various environmental education programs seek to raise the eco-friendly awareness and knowledge of staff as part of efforts to reduce environmental pollution. In 2021, SK Group’s educational platform mySUNI provided all employees with the 17-hour course, “Eco-friendly Literacy”. This course covers waste recycling, new and renewable energy , and hydrogen and fuel cells, which constitute the core knowledge of ESG management, as well as RE100, energy-related projects and new businesses, and is designed to enable staff to fully understand the direction of the business. Going forward, environmental education programs will be continuously developed, keeping pace with our project expansion.

08. Environmental Management Information System

To promote transparent environmental management, SK ecoplant discloses our sustainability report every year, covering the environmental information (energy, GHGs, waste, water, etc.) of our headquarters and all business sites. This report is submitted to the Ministry of Environment and other governmental agencies. Using the SEIS+, our company-wide environmental management system that was established based on environmental laws, we are monitoring the status and performance of our HQ and domestic business sites with respect to environmental management in real time. Continuous monitoring is also provided for waste, noise and vibration, air pollutants and water pollutants (COD, BOD) in order to manage environmental risks. While we have no environmental pollution management facilities of our own, we conduct environmental due diligence for facilities belonging to suppliers within our project sites and manage related matters accordingly.
We also operate the Environment Management Information System (EMIS) to manage all environmental information, such as the use of energy, waste, raw and subsidiary materials, and water at all sites. We aggregate site-specific data on a monthly basis through the EMIS, and the aggregated data is used to analyze monthly or annual energy consumptions and GHG emissions, depending on different purposes. In 2022, we expect to improve the standard of our EMIS by including EMIS enhancement in the KPIs of our quality and environment division.

09. Use and Recycling of Water

SK ecoplant conducts environmental audits and other water recycling activities to monitor water consumption at our domestic and overseas operations and to enhance water quality. Large-scale construction sites for infrastructure and plants are equipped with waste water treatment facilities to keep the amount of the treated waste water within permitted limits, as well as to reuse water, an important raw and subsidiary material in the construction industry, in on-site sprinkling, washing, landscaping, and cleaning to reduce water consumption. Also, stored rainwater that flows in from the rainwater harvesting system, treated waste water, and effluents are used as reclaimed waste water. In 2022, we are implementing a plan to install rainwater and effluent ground water recycling facilities to proactively improve environmental efficiency indicators.

10. Biodiversity Protection

SK ecoplant conducts environmental impact assessments before construction to minimize the environmental impact on local communities. For the protection of ecosystems, we first identify environmental impact assessment factors, deduce any potential adverse impacts, and then establish and implement reduction plans, aiming to minimize ecological disturbances. As part of such efforts, we assemble piles of rocks to provide shelters for organisms and allow for their migration and habitation, and install perches to provide rest and feeding areas for birds. In addition, we lay megaliths to aid the inhabitation and spawning of fish, and install aeration facilities in water and ponds for oxygenation. Further.

11. Response to Environmental Accidents

SK ecoplant carries out environmental examinations of our HQ and business sites, based on ISO 14001, to assess potential environmental risks and the operational status of the company-wide environmental management system, as well as to come up with countermeasures for environmental accidents. We have established a response guideline for all our domestic and overseas sites in preparation for potential environmental damage. Emergency training exercises are held every year to prevent pollution from spreading through emergency reporting and fast response, with secondary damage avoided through decontamination and environmental restoration.

12. Chemical Safety Management

SK ecoplant has established and is operating a chemical management process for safe chemical management. In the case of chemical products brought to all workplaces, prior information and MSDS data on the type, quantity, storage location, usage method, and protective equipment of chemical products are checked through construction meetings before working.
We are trying to reduce risk of chemical products by posting and education workers on precautions to be taken when handling and disposing of them, and listing high -risk substances, and replacing them with low-risk substances. Designated waste such as waste oil and waste paint generated from business partners during construction are classified and disposed on Waste Management Act. In addition, designated waste storage facilities are installed and operated to prevent environmental pollution caused by designated waste outflows. The chemical products management status is checked from time to time to prevent safety and environmental accidents.
To prevent safety accidents and occupational diseases, the safety and health manager conducts daily inspections of hazardous chemical handling sites and storage sites, and the environmental manager checks all workplaces for violations of chemical management at least twice a year.
