Environmental Management

Greenhouse gas emissions are the primary factors for causing climate change. Starting 2025, MediaTek introduced a carbon management system, using the operational control approach to assist in conducting consolidated company GHG inventory and assurance operations. The Company will continue to use the carbon management system for operations in the future to fully grasp the GHG emission situation. MediaTek’s GHG emissions from energy and resource use include purchased electricity, public utilities, boilers, cooling towers, and chillers, with the primary emission source being Scope 2 purchased electricity accounting for 96.29% of total emissions. Despite continued growth in the Company’s operational scale, we are committed to improving energy use efficiency and planning renewable energy use to reduce GHG emissions from operations. Major reduction measures in 2025 include expanding use of self-generated solar renewable energy, continuously improving data center energy efficiency, using LED lighting in all offices, and chiller group co-supply to reduce operating units, thereby improving electricity efficiency. Additionally, the Company continues to monitor climate actions including the global Renewable Energy Initiative (RE100), planning to use 2020 as the baseline year (baseline year total Scope 1 & Scope 2 emissions of the Company and consolidated financial report subsidiaries: 84,545 ton CO2e), reducing Scope 1 and Scope 2 by 40% by 2030, and achieving the net-zero emission target by 2050. The Company simultaneously commits to achieving 100% renewable energy for global group office electricity (excluding data centers) by 2030, and 100% renewable energy use for the entire global group by 2050 as a long-term target. Increasing renewable energy use is currently one of the main corporate carbon reduction methods globally and is a necessary means for MediaTek to reduce GHG emissions. In 2026, the Company will expand renewable energy procurement, with planned annual use of 50 million kWh of externally purchased solar power, carbon reduction of approximately 23,700 tons, representing approximately 18.7% reduction compared to 2025 group-wide carbon emissions. The Company will continue to expand renewable energy use in subsequent years to progressively achieve corporate GHG reduction goals.

Planning to use 2020 as the baseline year, reduce Scope 3 GHG emissions (purchased goods or services, fuel and energy-related activities, use of sold products) by 25% by 2030. To this end, the Company will continue to promote various upstream and downstream reduction measures, working hand-in-hand with value chain partners toward the 2050 net-zero emission target. To effectively reduce carbon emissions from employee commuting, MediaTek proactively implements environmental measures through transportation-related issues closely relevant to employees, reducing transportation carbon emissions by approximately 435 ton CO2e in 2025. In addition to maintaining fixed-route bus shuttles and electric shuttles between offices, 21 electric vehicle charging stations have been installed, concretely responding to low-carbon trends. Additionally, in March 2023, MediaTek partnered with Gogoro to launch the first corporate battery-swapping station in the Science Park, with cumulative carbon reduction reaching 225 metric tons from launch through the end of 2025.

*In accordance with the GHG Protocol, MediaTek conducted a greenhouse gas inventory and reported Scope 3 Category 3 emissions (Fuel- and Energy-Related Activities Not Included in Scope 1 or Scope 2), which amounted to 18,319.348 tCO₂e in 2025. Scope 3 Category 13 (Downstream Leased Assets) and Category 14 (Franchises) were deemed not applicable, as the Company had no relevant activities under these categories. The inventory covered the Hsinchu Science Park, Zhubei, Taipei, and Tainan offices.

*ISO 14064-1 verification was obtained in 2025, covering the greenhouse gas inventory of all global offices across the Group.

MediaTek 2025 GHG Emission Type Statistics

Note 1: GWP values refer to the IPCC's 6th Assessment Report.
Note 2: For electricity emissions factors, all global locations across the group use the latest officially published electricity emissions factors at the time of verification. For example, in Taiwan, the electricity emission factor for 2024 is 0.474 kg CO₂e/kWh.

MediaTek's habitat volunteer action visited the Nature Valley Environmental Trust base to assist in bamboo forest thinning operations. The thinning area in 2025 was approximately 0.3 hectares, part of the 1.2-hectare trust land managed by the Company. Moderate thinning helps improve stand structure, reduce competition, and enhance health, thereby increasing subsequent carbon sequestration and reducing pest and disease issues. Through hands-on participation in habitat management, employees deepen their awareness and understanding of natural ecology conservation. This action successfully responds to Taiwan's 2050 Net-Zero Transition "Natural Carbon Sinks" key strategic action of "Forest 2-2: Promoting aging bamboo forest renewal to revitalize bamboo forest carbon sequestration capacity."

MediaTek deeply recognizes the importance of biodiversity to the Earth's ecosystem. Since 2024, MediaTek has partnered with the Tse-Xin Organic Agriculture Foundation to actively implement tree planting and afforestation plans. As of 2025, 2,000 saplings have been planted in areas including Zhubei Crescent Bay coastal forest and Yilan Wujie coast, with estimated annual carbon sequestration of 13.1847 (ton CO₂e/year). This action successfully responds to Taiwan's 2050 Net-Zero Transition "Natural Carbon Sinks" key strategic action of "Forest 1-1: Implementing new afforestation on national, public, and private lands to increase forest coverage and carbon sink capacity."

Additionally, MediaTek also plans to donate NT$1 million to the Tse-Xin Organic Agriculture Foundation for subsequent coastal forest tree maintenance. Looking ahead, MediaTek plans to continue recruiting employees for volunteer tree planting activities in 2026, jointly maintaining biodiversity and supporting forest conservation through actual participation in afforestation, while raising employees' awareness of natural ecology conservation and responding to ecological conservation principles through action.

MediaTek's building constructed in the Miaoli County Tongluo Science Park established diverse biological habitats, preserving 9 existing trees including Trema orientalis, and following the "right tree in the right place" principle, additionally planting 194 native species trees across an area of approximately 0.23 hectares, with estimated annual carbon sequestration of 1.3382 (ton CO₂e/year) Note. Additionally, at the HC-F building in the Science Park, tree habitat remediation and brown root rot disease control programs were conducted, preserving a total of 113 existing precious native tree species including slash pine, Japanese black pine, and camphor trees. The preserved native trees have an estimated annual carbon sequestration of 0.7449 (ton CO₂e/year)Note.

Furthermore, MediaTek's India office also participated in the "Sustainability Hope Saplings" activity in 2025, with MediaTekers volunteers planting 28 saplings, injecting green vitality into the new office site. In the future, MediaTek will continue to pay attention to biodiversity-related issues, gradually incorporating nature-positive concepts into operations and decision-making processes, reducing potential impacts on the ecological environment through concrete action plans, and working with stakeholders to promote ecological conservation and sustainable development, advancing toward nature-positive goals.

Note: The method for estimating tree carbon sequestration refers to the data from the "Fourth National Forest Resources Survey Report" and the "National Greenhouse Gas Inventory Report - Chapter 6: Land Use, Land-Use Change, and Forestry Sector." On average, forests store about 9.89 tons of CO2 per hectare per year. Also, according to the "Guidelines for Incentivized Afforestation Species and Planting Density per Hectare," for non-timber forests, the standard number of native woody plants per hectare is 1.500. This information serves as a reference for estimating carbon
