Microsoft’s Climate Challenge: The Fossil Fuel Dependency of its Supply Chain

by Editorial Team

Microsoft, a tech behemoth, has set ambitious climate goals, aiming to become carbon negative by 2030. However, the company’s supply chain, heavily reliant on fossil fuels, poses a significant hurdle to achieving this target. This article delves into the complexities of Microsoft’s supply chain and the challenges the company faces in aligning its suppliers with its climate objectives.

Microsoft’s Climate Ambition and the Supply Chain Challenge

In 2020, Microsoft’s CEO, Satya Nadella, announced the company’s commitment to achieving carbon negativity within a decade. This ambitious goal involves not only reducing emissions from Microsoft’s operations but also across its entire supply chain. However, the latter has proven to be a monumental task.

Case Study: Chicony Electronics

Chicony Electronics, a Taiwan-based electronics supplier for Microsoft, exemplifies the challenges in aligning suppliers with Microsoft’s climate goals. In 2021, Chicony’s CO2 emissions skyrocketed by almost 700 percent from the previous year, following the expansion of its factories in Thailand and China. This case is not an isolated incident, as many of Microsoft’s suppliers have not aligned with the company’s climate targets.

The Fossil Fuel Dependency

A review of 27 emissions inventories from Microsoft’s top 100 suppliers revealed that most had increased their emissions since Microsoft announced its climate ambitions. Some suppliers did not even have a single contract for renewable energy, implying that their entire electricity consumption was sourced from fossil fuels.

The Impact of the Pandemic

The COVID-19 pandemic has also played a role in the increase in emissions. The surge in demand for computers, laptops, and smart devices led to an increase in production and, consequently, emissions. For instance, Hynix, a South Korean semiconductor manufacturer, reported a 1.19 percent increase in emissions in 2021 due to increased demand for its products.

The Road Ahead

Microsoft’s struggle to control its supply chain emissions is not unique. Most big tech companies face similar challenges due to their global supply chains. However, some companies, like Apple, have made significant progress in cleaning up their supply chains by supporting their suppliers in reaching 100 percent renewable energy by 2030.


Microsoft’s journey towards carbon negativity is fraught with challenges, particularly in managing its supply chain emissions. While the company has made strides in reducing emissions from its direct activities, the task of aligning its suppliers with its climate goals remains a significant hurdle. As Microsoft grapples with this challenge, it serves as a reminder of the complexities involved in achieving sustainability in a globalized world.
