Environmental Management
We are firmly committed to concrete action for the promotion of environmental protection, energy conservation, and carbon reduction in search for potential responses and adaptations for climate change mitigation. 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.
▌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 sustainable development 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 2024, total environmental expenses amounted to NT$90.21 million:
▌Green Bonds and Responsible Investment
As of 2025, our cumulative investments in green bonds total approximately NT$1.6 billion.
In 2025, we added an NT$100 million investment in a green bond (short name: P14 TSMC 3A, code: B618E2), which is recognized by the Taipei Exchange (TPEx) as a Green Bond.
▌Energy Management
In response to industry expansion, MediaTek continued to expand its IT data center scale in 2024, which consumed 190,603,000 kWh of electricity, a 6.6% increase compared to the previous year. Although total electricity consumption increased, MediaTek remains dedicated to energy-saving and carbon reduction measures. This year, our electricity saving ratio reached 16.5%, successfully achieving the 16.5% target set in 2023. We will continue to plan and implement various energy reduction measures while maintaining the 16.5% electricity saving target for 2025.
1. High-density, energy-efficient data centers
Limitations of traditional centers have been overcome through improvements of power systems, air conditioning, cabinets, corridors, and lighting, successfully transforming into a new-generation high-density, energy-efficient data center which can support the demands of the latest high-energy, high-heat servers and provides powerful backing for technology R&D. The overall PUE performance of our new data centers is 1.33, a significant 17% improvement in energy efficiency compared to 1.6 PUE for traditional server rooms, thus meeting the Leadership in Energy and Environmental Design (LEED) Gold certification standard for
green buildings, total electricity saving benefit: 20.3 million kWh.
2. Using LED energy-efficient lighting in all operational buildings
Six buildings originally used energy-intensive fluorescent lights. All were replaced with energy-efficient LED lighting by 2024, with an investment exceeding NT$ 70 million. This change results in an electricity saving benefit of approximately 6.5 GWh a year. Eight buildings, constructed after 2019, are equipped with energy efficient LED lighting from the outset, with over 11,000 fixtures. This provides an electricity saving benefit of approximately 1.9 GWh a year. MediaTek has successfully achieved its goal of having all office buildings use energy-efficient LED lighting. This continuous improvement effort has been recognized and rewarded with energy-saving subsidies from the Ministry of Economic Affairs and the Taipei City Government.
3. Self-generated solar power plants
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 governments green energy policy as an early adjustment to the impact of climate risks on the Companys 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 2024 amounted to 1.09 GWh. In 2024, electricity generated was approximately 176,000 kWh (634 GJ). Compared to the electricity consumption of 190.6 million kWh (686,171 GJ) in 2024, this accounts for approximately 0.1%.
Additionally, four other rooftop solar power plants were completed and connected to our internal network by the end of 2024, to provide power for self-consumption, with a total installed capacity of 709 kW. We plan to add a rooftop solar power plant at the new Tongluo Data Center in 2025, with an installed capacity exceeding 200 kW.
▌Greenhouse Gas Emission Management
- Scopes 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 95.74% of Scope 1 & 2 emissions. As the Companys scale of operations continues to grow, we are committed to improving energy efficiency and planning for renewable energy use in order to reduce greenhouse gas emissions from our operations. The main reduction measures in 2024 include continuous improvements to data center energy efficiency, the use of LED lights in all offices, and the linked supply and reduced operation of chiller units to enhance electricity efficiency. In addition, the Company continues to pay attention to various climate actions, such as the Science Based Targets (SBT) that limit the global temperature rise to 1.5° and the global renewable energy initiative—RE 100. In the first half of 2025, we successfully passed the SBTis review. With 2020 as the baseline year, we target a 40% reduction in Scope 1 and Scope 2 emissions by 2030 and aim to achieve the SBT net-zero target by 2050. We also commit to achieving 100% renewable energy use for at the Groups offices worldwide (excluding data centers) by 2030. Enhancing the use of renewable energy is currently one of the main ways to reduce carbon for companies around the world, and it is also MediaTeks essential approach to reduce greenhouse gas emissions. Therefore, the company will continue to plan the renewable energy use target in two years, in order to gradually realize the effectiveness of corporate greenhouse gas reduction。
- Scope 3 GHG Emissions - Shuttle Bus Services
In accordance with MediaTek's SBT commitment, we aim to reduce Scope 3 greenhouse gas emissions (from purchased goods and services, fuel- and energy-related activities, and use of sold products) by 25% compared to the baseline year 2020. To achieve this, we will continue to promote various upstream and downstream reduction measures, and collaborate with our value chain partners to work toward the 2050 SBT net-zero target.
* In 2024, Scope 3 Category 3—Fuel- and energy-related activities not included in Scope 1 or Scope 2—totaled 18,623.70 tCO2e. Category 13 (Downstream leased assets) and Category 14 (Franchises) are not applicable (N/A) as the company has no such activities. The data boundary covers the Hsinchu Science Park, Zhubei, Taipei, and Tainan offices (100% coverage).
▌Water Resource Management
MediaTek's offices source water from local water treatment plants. In 2024, with the continued expansion of our IT data centers and an increase in employee numbers, we consumed a total of 525,064 metric tons (approximately 525 million liters) of water, representing a 3.6% increase from the previous year. Despite the increase in total water consumption, MediaTek continues to implement water resource improvement plans and various water reduction measures, thus achieving total savings of approximately 23,376 metric tons. In terms of risk management, the WRI Aqueduct tool was used to simulate the IPCC RCP 8.5 scenario to simulate and confirm that the sites in Taiwan are not located in areas with high water stress.
Our wastewater is mostly domestic sewage. It is discharged into natural water bodies upon treatment in wastewater plants in a unified manner in accordance with regional regulations to avoid local environmental impacts. The total discharged wastewater quantity of 218,300 metric tons (around 218 million liters) in 2024 is 1.6% more than the previous year for the same reason as the said increase water consumption.
▌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 2024, our waste treatment and recycling rate was 27%. We will continue to increase the recycling rate or reduce the amount of non-recyclable waste to achieve continuous improvement goals. 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.
▌Environmental Protection and Biodiversity
Following the official release of the Taskforce on Nature-related Financial Disclosures (TNFD) in 2023, global attention to biodiversity issues has grown significantly. MediaTek recognizes the critical importance of biodiversity to the Earths ecosystems and understands the key role that forests play in maintaining ecological balance, regulating the climate, and providing essential resources for human survival. Therefore, MediaTek supports international initiatives such as the United Nations Convention on Biological Diversity (CBD), the Kunming-Montreal Global Biodiversity Framework (K-M GBF), as well as the Sustainable Development Goals (SDGs). We have drafted MediaTek Biodiversity Statement in 2024, which is scheduled for release in 2025.
