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 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°C, 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.
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.

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.
The construction of MediaTek's Hsinchu HSR Office Building began in 2024. During the overall building construction period from 2022 to 2027, MediaTek is partnering with National Taiwan University on an industry-academia collaboration project. The existing century-old banyan tree and the "Shisan Jia Bogong Temple" on the site will be transformed into an old tree cultural park and civic plaza for public recreation. We have invested over NT$ 10 million in project funding for the maintenance of large trees during construction, including pest and disease control, nutritional supplementation, aerial root guidance for structural improvement, tree shaping and pruning, and habitat soil improvement, to minimize the impact on the banyan tree's growth during construction. In addition, MediaTek will construct an elevated connecting bridge and open it to the public. Besides connecting Hsinchu HSR Station and the new office building, the bridge will extend to the Hsinchu Biomedical Science Park behind the building, to facilitate public access and demonstrate MediaTek's care and commitment to the community.
At the newly constructed HC-F building in the Hsinchu Science Park, we invested NT$ 3.5 million in protection plan for tree habitat remediation and brown root rot treatment. This effort preserved 113 existing precious native tree species, such as Loblolly Pine, Japanese Black Pine, and Camphor trees, contributing to the ecological environment of the Hsinchu Science Park.
At the building under construction in the Miaoli Tongluo Science Park, MediaTek has invested NT$ 6.6 million to create diverse biological habitats. This includes the preservation of 9 existing native trees such as Pigeon Wood, with the addition of 194 newly planted native trees, which is built with a multi-layered planting design to create a small forest. In terms of building materials and construction methods, all areas within the site, except roads, are paved with grass pavers to achieve permeability and greening effects. The green belt drainage system features pebble ditches for water retention, ensuring that the entire site is equipped with both natural preservation and water permeability/retention functions.
