MS may require its large suppliers to use 100% carbon-free electricity by 2030.

Microsoft has significant influence in the technology sector due to its extensive supply chain and dominant market position. The company's move to force suppliers to comply with the new guidelines is likely to reverberate across the industry and could ultimately have a significant impact on decarbonization efforts.
Microsoft's major suppliers include Samsung Electronics, SK Hynix, and Realtek. These companies are setting renewable energy targets, but they are likely to incur high costs associated with this.
