Climate Change

Socionext Group believes that it can facilitate the transition to a sustainable society by using the SoCs we supply to help our customers achieve ongoing reductions in their GHG emissions. By collaborating on development with major customers who are leaders in their global markets and through the development of high-performance custom SoCs that leverage our proprietary multicore design techniques and AI engines and accelerators with lowpower consumption, we will achieve further miniaturization, higher levels of integration and lower power consumption of customer products and contribute to our customers' innovation. In the fiscal year ended March 31, 2024, we identified the following climate change “risks” and “opportunities” in our group business activities and calculated their financial and business impacts by scenario analysis.

Specific actions regarding Risks and Opportunities

In recent years, with the development of self-driving technology and the beginning of the use of generative AI in the market, the computing power required is expected to increase exponentially, making it a social issue to reduce power consumption and GHG emissions. To maintain and improve market competitiveness and counter rising energy costs, the Group is working to reduce power consumption from the development stage.

(1) Efforts to reduce LSI power consumption of LSIs

[Reduced power consumption by miniaturization]

In order to meet customers' demands for lower power consumption of LSIs, the Group is pursuing advances in process nodes (miniaturization and lower voltages) to achieve lower power consumption. Comparing the power consumption of advanced and existing processes, the most advanced 2nm/3nm process consumes approximately 1/10 or less per transistor compared with the 28nm process.

[Visualization of reduced power consumption by miniaturization and lower voltage]

[Design technology to achieve low-power consumption]

he SoC design of the Group is taking a variety of approaches to meet customers' demands for low-power consumption. To realize low-power LSIs, it is effective to combine various technologies, not only using individual technologies (see figure below). “Reference design flow,” the Group's design environment, can respond to various low-power technologies and reduce power consumption of LSI's both during operation and standby. In particular, we are systematizing and developing methods to reduce power consumption by controlling the power supply.

In addition, by adopting UPF/CPF*, the Group facilitates low-power consumption design while minimizing changes to the customer’s design assets. The adoption of UPF/CPF enables highly reliable designs for lowpower technologies, which have been extremely difficult to verify in the past.

*:UPF (Unified Power Format) is a standard specification that defines the Low power design guidelines standardized as IEEE Std. 1801 CPF (Common Power Format) is a standard specification that defines the Low power design guidelines standardized as Si2

[Low-power-consumption technology]

Low-power-consumption technology

[Design/development processes and packaging technologies that enable low power consumption]

In order to achieve low power consumption in our customers' products, we have established and operate our own development flow (“Design Review” mechanism). Specifically, we contribute to the reduction of GHG emissions at various stages from product manufacturing to putting in use by listening to customers' requirements for low power and determining specifications, proposing technology selection (including process node selection) to realize the requirements, and selecting foundries and OSATs that are proactive in measures to reduce environmental impact including GHG emission reduction, among other initiatives. In the development stage, we are working on logic/physical design and package design (2.5D, 3D, chiplet strategy, etc.) oriented toward low power consumption and miniaturization, and contributing to the reduction of GHG emissions through SoC products.

As described above, the Group contributes to the reduction of power consumption at our customers' end by developing and providing advanced technology products and products incorporating diverse low-powerconsumption technologies. In terms of sales trends by process node, both product sales and NRE revenue are shifting toward advanced technology products (3nm to 7nm). NRE revenue (for the fiscal year ended March 31, 2024), a leading indicator of future product sales, show that advanced technology products account for 71% of total sales.

(2)Efforts to reduce size and space
The Group contributes to the reduction of materials used (mineral and fossil resources) by miniaturizing LSIs and to the reduction of energy consumption in the manufacturing process, from raw materials to finished products. Miniaturization of LSIs leads to smaller size and space-saving in customers' end products, and also leads to easier countermeasures against heat generation during equipment operation. We believe that, in addition to reducing the material used and energy consumed in manufacturing process by our customers, it leads to the realization of a sustainable society by reducing energy when using finished products (for example, improved cruising distance of electric vehicles, reduced burden on air conditioners in data centers, etc.). In recent years, chiplets represented by 2.5D and 3D integration technologies have entered the practical stage and are expected to be a breakthrough against the limits of LSI miniaturization. By actively promoting the adoption of this technology, the Group is promoting further miniaturization, space-saving designs, and low power consumption.

(3)Efforts to Reduce Power Consumption at Data Centers
The shift in development to advanced technology products (2nm to 7nm) has led to an increase in the volume of data processing in data centers, and power consumption now accounts for about half of the Group's GHG emissions (the sum of Scope 1 and 2). As the scale of our business expands in the future, power consumption is expected to increase further. As a measure to reduce power consumption in data centers, the Group is sequentially introducing and replacing its equipment with low-power-consumption devices, primarily CPUs and servers. In addition, we are working to reduce power consumption by curbing CPU/server operating time through streamlining operations by improving development processes, methods, etc. Other efforts to reduce power consumption include consolidating data centers and shifting to water cooling for the installed equipment.

Indicators and Targets for Climate Change Response

GHG emissions (Scope1*1 and Scope2*2) by the Group for the fiscal year ended March 31, 2024, were approximately 8,198 t-CO2. Compared with the previous year, this represents a reduction of 336 t-CO2. GHG emissions per net sales were 3.71 t-CO2, a reduction of 0.72 t-CO2 compared with the previous year. We have set a goal for the group of becoming carbon neutral by 2050 in terms of both Scope1 and Scope2 emissions, and we are continuing to investigate and implement reduction measures that will help us achieve this goal.
