Microsoft Corp is a multinational technology company that is headquartered in Redmond, Washington, United States. The company was founded in 1975 by Bill Gates and Paul Allen, and has since grown to become one of the largest and most influential technology companies in the world. Microsoft operates in the Infrastructure Software sector, providing software and services to businesses and consumers around the globe.

In recent years, Microsoft has become increasingly focused on decarbonisation and reducing its carbon footprint. The company has set ambitious targets to become carbon negative by 2030, meaning that it will remove more carbon from the atmosphere than it emits. This is a significant challenge, but Microsoft has already made significant progress towards this goal.

One of the ways in which Microsoft is working to reduce its carbon footprint is through its corporate energy strategy. The company has committed to sourcing 100% renewable energy for its data centers, offices, and other facilities by 2025. This means that Microsoft is investing in renewable energy projects such as wind and solar farms, and purchasing renewable energy credits to offset its carbon emissions.

Microsoft is also exploring new ways to generate renewable energy on its own sites. For example, the company has installed solar panels on the roof of its Silicon Valley campus, which generate enough electricity to power 2,000 homes. Microsoft is also experimenting with new technologies such as hydrogen fuel cells, which could provide a clean and efficient source of energy for its data centers.

Another key part of Microsoft's corporate energy strategy is the use of corporate power purchase agreements (PPAs). A PPA is a long-term contract between a company and a renewable energy provider, which guarantees a fixed price for the electricity generated by the provider. By signing PPAs, Microsoft is able to support the development of new renewable energy projects, while also securing a reliable and cost-effective source of electricity for its operations.

Microsoft has signed several high-profile PPAs in recent years, including a 15-year agreement to purchase 90 MW of energy from a wind farm in Texas. This PPA will provide enough electricity to power 45,000 homes, and will help Microsoft to achieve its goal of sourcing 100% renewable energy by 2025.

In addition to its corporate energy strategy, Microsoft is also working to reduce its carbon footprint through a range of other initiatives. For example, the company is investing in carbon capture and storage technologies, which could help to remove carbon dioxide from the atmosphere and store it safely underground.

Microsoft is also exploring new ways to reduce the carbon footprint of its products and services. For example, the company is developing new software tools that can help businesses to track and reduce their carbon emissions. Microsoft is also working to make its products more energy-efficient, and is exploring new materials and manufacturing processes that could help to reduce the environmental impact of its hardware products.

Overall, Microsoft is a company that is deeply committed to decarbonisation and reducing its carbon footprint. The company's corporate energy strategy, which includes a focus on renewable energy and corporate PPAs, is a key part of this effort. By investing in clean energy and exploring new technologies, Microsoft is helping to drive the transition to a low-carbon economy, and is setting an example for other companies to follow.
