NHN

NHN strives to minimize environmental impact throughout all business activities and create a better natural environment and sustainable daily lives through its technology and services. In our vision to implement an eco-friendly management, we have established environmental and energy policies and have installed and operated a department dedicated for an environmental management such as the ESG Environment and Energy Technology Team.

Environmental Management System

Environment and Energy Policy

NHN establishes and implements the following Environmental and Energy Policy to minimize negative environmental impacts that may occur by providing various IT-based services, and
actively respond to global climate change issue by improving energy efficiency and
minimizing GHG (greenhouse gas) emissions.

All NHN executives and employees must participate and practice energy and environmental management activities to implement the policy in an active manner.
NHN follows relevant laws and guidelines regarding energy and environmental regulations.
Reduce GHG emissions by applying energy-efficient technology and increasing the use of renewable energy.
Reduce waste, conserve resources and consistently strive to solve the environmental problems.
Purchase eco-friendly and highly energy-efficient product by priority.
Inspect energy and environmental impact regularly and disclose the results to the stakeholders.
Encourage activities for preserving biodiversity and protecting ecosystems.

Environmental and Energy Management System Certification

NHN has acquired both environment management system (ISO 14001) and energy management system (ISO 50001) certifications for its headquarters building Play Museum and Play Hub (NCC1), its data center in Pangyo in August 2022. NHN has been pushing ahead with eco-friendly management in a systematic manner by adopting an environment and energy management system that meets the global standards throughout its overall business activities. At the same time, acquiring environment and energy management system certification is a representation of our efforts to contribute to 13 goals in areas including human, earth and prosperity among 17 Sustainable Development Goals (SDGs) proclaimed by UN. We plan to conduct a management review periodically by an accredited external organization to be evaluated and verified of our performance made in the environment.

Urban eco-friendly Data Center

NHN’s data center ‘Play Hub (NCC1)’ in Pangyo is an eco-friendly data center that applies various energy-saving technologies.
It boasts high energy efficiency with PUE 1.2~1.3. We strive to develop and introduce better eco-friendly technologies through continuous energy saving projects, not being complacent with the current energy efficiency. Based on the energy saving projects carried out from 2017 to 2021, NCC1 is saving about 4.45 million kWh of electricity per year which can also be interpreted as 510 million won of energy costs per year.

* PUE(Power Usage Effectiveness) : As a value obtained from dividing the total electricity used in the data center by the amount
consumed by IT equipment, the closer to 1, the more energy effective.

Eco-friendly Elements at NCC1
Enhance Energy Efficiency	Maximized cooling efficiency by applying the first patented ‘indirect evaporative cooling system’ in Korea and HVAC on the ceiling. Minimized power loss by separating cold and hot aisle by installing containment. Lowered the outside air temperature sucked into the HVAC by about 3°C with a mist spray device. Continue energy-saving efforts such as installing cooling fog for generator air inlet in 2020, reinforcing HVAC insulation, changing server room operating conditions and improving air-conditioning efficiency by upgrading the pre-filter replacement in 2021
High-density Operation Environment	Built a modular server room considering the IT life cycle, developed/applied its own rack with adjustable width Provides an optimized operating environment for cloud computing, such as high- density capacity and UPS power supply

Eco-friendly Office

The Play Museum, NHN’s headquarter building, was constructed as an eco-friendly office space from the design stage, mindful of eco-friendly space planning, facilities and materials. The Play Museum has acquired the ‘Platinum’ certificate in 2013 which is the highest level in LEED (Leadership in Energy and Environmental Design), a renowned program for accrediting eco-friendly construction as it was highly praised for its efforts to carefully consider the impact on the environment when constructing the building as well as the surrounding environment, from site and material selection to energy efficiency.

Eco-friendly Elements at Play Museum
Energy Reduction Policy	Product to reduce power and water consumption Annual power consumption is reduced by 25% compared to conventional fluorescent lamps by installing LED lights in public spaces. Water-saving devices, standby power cut-off systems, auto-lighting control. Natural light and ventilation Natural light with vertical louvers, natural ventilation through hive and rooftop windows. Improved space efficiency and reduced power consumption when moving Enhanced space efficiency and reduced power consumption when moving by making multi-purpose space on the first basement level. Staircase are located on the center of the building with easier accessibility and 41.7Wh of electricity is saved as stairs are used more often instead of elevators.
Construction Material	Used minimal construction material and discarded minimum waste Space planning void of columns so that it can be easily rearranged. Conference tables made according to the size of raw materials for minimal waste. Use materials in consideration of nature's recovery rate Selected materials that emit lesser organic compounds and do not contain formaldehyde or resin. Chose eco-certified bamboo access floorboards made from waste-paper and used a packing box as a finishing material.
Environmental Impact Reduction Strategies	Minimize Carbon Emissions Approx. 514 kg of greenhouse gas are less emitted per day by operating a bike parking lot that can accommodate up to 130 bicycles. Environmental Pollution Management Plan Implemented an environmental pollution management plan to reduce pollution from the construction site. Reduce Indoor Air Pollution Built with an adhesive-free structure and used eco-friendly adhesives, if needed. Generating fresh air by planting many greens.

Environmental Movement

NHN has been in the forefront of engaging in various eco-friendly activities which is also participated by its members in their daily lives. NHN strives to form a company-wide consensus on environmental management and to encourage every day practice. From 2021, office supplies and consumables for in-house facilities are replaced with eco-friendly products and reusable items. We have been running various campaigns regularly such as the 'Good Use' campaign that collects and reuses unused items as well as ‘Energy Use Data Sharing’ to enhance the awareness on how much energy has been used internally.

In-house Eco-friendly Actions

Type	Activities	Contribution to the Environment
Use Ecofriendly Products	Replaced the packaging in the company’s OA booth to paper buffer and paper tape. Prepared recycled paper. Replaced the take-out lunch box at the cafeteria with pulp container. Offer multi-use cutlery and shopping bag rental service at the in-house convenience store. Use sugarcane cups, PLA straws and offer discounts for tumblers use at the in-house cafe. Made a journal package using eco -friendly materials and techniques.	Used 530 square meters of paper cushioning instead of a plastic air cap. Used 350,000 sheets of recycled paper, protecting about 20 trees. Used 2,214 eco-friendly containers instead of plastic lunch boxes. Used 2,400 sets of multi-use cutleries, reducing about 16kg of single-use waste. Used about 20,000 eco-friendly cups & straw as well as 1,700 tumblers, reducing 693kg of greenhouse gas emission.
Environmental Campaign	Led the ‘Good Use’ campaign to encourage sharing and reuse of unused consumables in the company. Participated in ‘Lights Out’ events every year celebrating the Earth Day and Earth Hour. Display monthly in-house energy use through the screen installed.	Reused 272 consumables through the ‘Good Use’ campaign in December 2021. Resulted in reducing greenhouse gas (2,660 kg), the same amount of gas absorbed by 403 30-year-old pine trees for 1 year through the light-out event to celebrate the Earth Day in April 2022.

※ Contribution to the environment has been calculated from Sep. 2021 until May 2022
