Environmental Management

In addition to taking the initiative in identifying and controlling climate risks, we are firmly committed toconcrete action for the promotion of environmental protection, energy conservation, and carbon reduction in search for potential responses and adaptations to climate change. We continue to implement energy conservation and carbon reduction measures in our office areas. The power-saving rate from 2017 to 2021 reached 10.1%~14.8%. In addition, we have set a target of 17.8% power savings for 2022.

| Environmental Policies

As a global, fabless semiconductor company, we specialize in IC design. All manufacturing operations including wafer production, packaging, and testing are carried out by commissioned manufacturers. MediaTek therefore prioritizes green product design, green procurement and management for subcontractors, reduction of resource and energy waste, and safeguarding of employee health and safety. This not only demonstrates MediaTek’s commitment to fulfilling its CSR but also represents a key asset securing the Company’s international competitiveness in the future. MediaTek proactively implements its environmental policies through four major management approaches. In 2021, total environmental expenses amounted to NTD56.5 million:

| Resource Management

MediaTek has passed the certification audit for ISO 14001 Environmental Management System. Consistency of environmental protection goals and implementation strategies is maintained by relying on the PDCA management cycle and through adoption of systematic management approaches. In addition, a pollution prevention and mitigation mechanism has been established to maximize MediaTek’s influence in the field of environmental protection. The Company has also passed the certification audit for the ISO 45001 Occupational Health and Safety Management System. The goal lies in the guarantee of workplace health and safety through systematic management. MediaTek operations are characterized by low energy intensity. Management of internally utilized energy resources can be divided into the five major dimensions of electricity, water consumption, waste management, transportation, and greenhouse gases

| Energy management and conservation

  • Highdensity, Energy-efficient Data Centers - Total power saving effects reach 20.3 GWh

Due to the fact that MediaTek specializes in the development of innovative technologies, it has a constantly rising demand in the field of data computing quality and quantity. The Company has made a long-term commitment to enhancing data center performance in consideration of the fact that the data center environment affects data computing efficiency and high-speed computing consumes large amounts of energy.

Under full load conditions, the three high-density, energy-efficient data centers generate annual
energy savings of 1.76 GWh (6,336 GJ), 4.34 GWh (15,624 GJ), and 14.2 GWh (51,120 GJ), respectively (total estimated power saving effects amount to 20.3 GWh or 73,080 GJ) compared to traditional data centers. Total carbon emission reductions are roughly equivalent to the annual carbon sequestration of 26 Daan Forest Parks.

  • Autonomously Developed energy-efficient chips  - Annual power savings of around 564 kWh per meeting room

The insufficient use of meeting room resources or frequent non-use of meeting room facilities after reservation coupled with the failure to turn off lighting and air conditioning after use results in resource waste. Meeting room usage statuses are therefore monitored with the MediaTek LinkIt 7697 by relying on the Company's own IoT network. Lighting and air conditioning are shut down automatically and the usage status is updated after personnel exits the room to achieve optimized usage of meeting room resources

MediaTek has over 100 meeting rooms. Daily and annual power savings per room amount to around 3 kWh and 564 kWh (2GJ), respectively. It is planned to expand the use in the security and resource dimensions in the future:

  • Solar Power System - Annual carbon savings amount to around 97 metric tons

Idle space on the rooftop of Building E of Corporate HQ has been utilized for the installation of a solar power system in line with the government’s green energy policy as an early adjustment to the impact of climate risks on the Company’s operations. This is the first Taipower grid-connected, rooftop-type solar power system installed by a private enterprise in the Hsinchu Science Park.

Upon installation of the system, the rooftop temperature has dropped by 3-5℃ , which allows reduced air conditioning use on the top floor of the Corporate HQ office building. The installed capacity of the PV system  which was connected to the Taipower grid in March 2019 equals 146.4 kW. Total power generation from March 2019 to December 2021 amounted to 0.55 GWh. Total power generation of the PV system reached 0.194 GWh (700 GJ), which accounts for 0.2% of the total power consumption of 123.49 GWh (444,568 GJ) in 2021. This system is expected to deliver carbon savings of around 97 metric tons CO2e annually. It is planned to initiate evaluations for installation of a second system in 2022.

| Waste Management

  • First enterprise in the Hsinchu Science Park area to set up a resource recycling machine in cooperation with EPA.

We reinforce waste management and prioritize waste reduction to realize the goal of resource recycling and reuse. Sorting, recycling, reuse, and proper treatment is carried out in a conscientious manner. In addition, ongoing improvements are implemented in the fields of waste storage, transportation, and treatment and environmental impacts. MediaTek selects qualified manufacturers for waste disposal and reuse operations in a rigorous manner and conducts non-scheduled audits of the legality of waste clearance processes to fulfill its supervision responsibility. 

In 2021, the waste treatment and recycling rate reached 35%. In addition, we are the first enterprise in the Hsinchu Science Park area to set up a resource recycling machine in cooperation with EPA and offer detailed information on our achievements as a reference for other companies.

| Greenhouse Gas Emissions

  • Scope 1 & 2 GHG emissions 

Sources of GHG emissions from resource use include purchased electricity, common facilities, boilers, cooling towers, and chillers. Purchased electricity, the main emission source, accounts for 92.1% of Scope 2 emissions. In the future, ongoing GHG inventories will be conducted to maintain a firm grasp of environmental impacts.

  • Emissions:

Purchased electricity represents MediaTek’s main emission source. In view of the constantly
expanding scope of our business operations, we are firmly committed to increasing our energy savings and thereby effectively decrease our GHG emissions. MediaTek has set an annual power-saving target of 11% (total power savings/total power consumption). The power-saving rate in 2021 equaled 14.8%, which can be attributed to the enhanced performance of the 2nd and 3rd data center compared to the previous year and the completion of LED lighting upgrades at Corporate HQ.

  • Scope 3 GHG Emissions - Shuttle Bus Services

With a view to reducing carbon emissions from employee commuting, MediaTek proactively adopts
environmental protection measures targeted at transportation issues which are of immediate
concern to employees. In 2021, carbon emissions generated from transportation amounted to
around 97 metric tons CO2e. In addition to the maintenance of shuttle bus services with specific
pick-up and drop-off locations and between office areas, the installation of EV charging stations
was completed in 2021 in line with low-carbon trends. Installation of three additional charging
stations and an e-scooter battery swapping station is planned for 2022.
