What You'll Learn
Microsoft's carbon emissions have increased by 30% since 2020
Data centres are buildings that store the computers and hardware needed to run IT services and applications securely. Cloud services providers like Microsoft operate huge data centres with multiple buildings that serve billions of users worldwide. While it is more energy-efficient for companies to store their data in a shared centre than to operate their own, these buildings are highly energy-intensive.
Microsoft has identified the need for collaboration across industries to develop and use greener building materials, like concrete and steel, and hardware components, like chips, to help reach its goal of becoming carbon negative by 2030. The company has also invested in carbon removal and storage, signing a deal to remove 3.3 million metric tons of CO2 from the atmosphere.
Microsoft's Scope 1 and 2 emissions, which are generated by the company's activities and the consumption of electricity or heat, decreased by 6.3% in 2023 compared to 2020. The company is also working to reduce its water consumption and has joined the Coalition for Water Recycling.
Microsoft's sustainability goals are challenged by its push into AI and cloud services, and the associated need for more data centres. However, the company is committed to investing in new technologies and expanding access to capital to stimulate the development of carbon removal technology.

The company aims to be carbon negative by 2030
The world confronts an urgent carbon problem, and Microsoft is committed to doing its part to address this challenge. The company has set an ambitious goal of becoming carbon negative by 2030, and it is taking a comprehensive approach to achieve this target.
Firstly, Microsoft plans to cut its carbon emissions by more than half by 2030, for both its direct emissions and its entire supply and value chain. This involves accelerating the shift from fossil fuels to renewable energy in its facilities and reducing emissions from its suppliers. Microsoft will also expand its internal carbon fee to charge for emissions from its supply and value chains, not just its direct emissions.
Secondly, Microsoft is investing in new technologies to reduce, capture, and remove carbon. The company has established a $1 billion Climate Innovation Fund to support the development of negative emission technologies (NETs), such as direct air capture, afforestation, reforestation, soil carbon sequestration, and bioenergy with carbon capture and storage (BECCS).
Thirdly, Microsoft is empowering its customers and suppliers to reduce their carbon footprints. It will develop and deploy digital technology to help its partners worldwide become more sustainable. The company has also debuted a sustainability calculator to help its cloud clients calculate and reduce their carbon emissions.
Additionally, Microsoft will encourage its employees to participate in carbon reduction and removal efforts. The company will create opportunities for employees to get involved in company-wide activities and within their individual teams.
Finally, Microsoft is committed to transparency in its progress towards carbon negativity. The company will publish an annual Environmental Sustainability Report, providing updates on its journey based on strong global reporting standards.
By taking these steps, Microsoft aims to become carbon negative by 2030 and remove all the carbon it has emitted since its founding in 1975 by 2050. The company recognizes the urgency of the climate crisis and is taking bold action to create a more sustainable future for all.

Data centres are the primary source of Microsoft's emissions
Microsoft's carbon emissions have risen by almost 30% since 2020, according to the company's annual Environmental Sustainability Report. This increase is primarily due to the construction of data centres, which serve as buildings that store the computers and hardware needed to run IT services and applications.
Data centres are highly energy-intensive, and with the rise of AI, Microsoft has seen a proliferation of these centres, driving up emissions. The expansion of these centres poses a challenge to the company's goal of becoming carbon negative by 2030. To address this, Microsoft has implemented a new requirement for its suppliers to use 100% carbon-free electricity by 2030 and is investing in the development of carbon removal technology through its Climate Innovation Fund.
Microsoft has also invested in renewable energy assets and carbon removal deals, aiming to source 100% of its electricity from carbon-free sources by 2030. The company is working to improve efficiency in its data centres, with AI playing a crucial role in increasing accountability and achieving technology breakthroughs. Additionally, Microsoft reused or recycled almost 90% of its servers and components last year, demonstrating its commitment to sustainability.
While Microsoft's data centres are the primary source of its emissions, the company is taking significant steps to reduce its carbon footprint and achieve its ambitious sustainability goals.

Microsoft's sustainability goals are challenged by AI and cloud services
Microsoft has set ambitious sustainability goals, including plans to become carbon negative by 2030 and to remove all the carbon the company has emitted since its founding by 2050. However, the company's push into AI and cloud services has challenged these goals.
Microsoft's carbon emissions have increased significantly since 2020, with a rise of nearly 30% attributed primarily to the construction of data centres. These facilities are highly energy-intensive and laden with carbon-intensive materials, including steel, concrete, and computer chips. As a leading cloud supplier, Microsoft's expansion of its data centres has resulted in increased indirect emissions from building materials and hardware components.
The company has acknowledged the need for collaboration across industries to develop and use greener building materials and hardware components. They have also invested in carbon removal technologies and renewable energy sources to address their carbon footprint. However, the rapid growth of data centres to support cloud and AI operations continues to challenge their sustainability goals.
Microsoft's sustainability report highlights the need to minimize water consumption and replenish more than consumed in their operations. They have also designed new data centres to support AI workloads without consuming water for cooling, aiming to reduce global reliance on freshwater resources. While Microsoft's sustainability goals are challenged by the expansion of their data centres for AI and cloud services, the company is actively working to address these challenges through various initiatives.

The company is investing in carbon removal and storage
Microsoft's carbon emissions have increased by almost 30% since 2020, according to the company's annual Environmental Sustainability Report. This increase is largely due to the construction of energy-intensive data centres, which support the company's growing cloud and AI operations.
To address this issue, Microsoft has invested heavily in carbon removal and storage. The company has signed a deal with Stockholm Exergi to remove 3.3 million metric tons of carbon dioxide from the atmosphere, the largest deal of its kind to date. Microsoft has also launched a $1 billion Climate Innovation Fund to invest in new technologies and expand access to capital for those working to solve the problem of carbon removal. This fund will primarily deploy capital in two areas: accelerating technology development through project and debt finance, and investing in new innovations through equity and debt capital.
In addition to its investments in carbon removal and storage, Microsoft is also working to improve efficiency in its data centres. The company plans to power its data centre operations with 100% renewable energy by 2025 and has implemented a new requirement for its suppliers to use 100% carbon-free electricity by 2030. Microsoft is also advancing circular hardware, having reused or recycled almost 90% of its servers and components last year.
Microsoft has set ambitious goals to become carbon negative by 2030 and to remove all the carbon the company has emitted since its founding by 2050. The company's investments in carbon removal and storage, as well as its efforts to improve efficiency and increase the use of renewable energy, are all part of its strategy to achieve these goals.
