Facebook, Inc. is a social networking web company based in the United States of America. The company was founded in 2004 by Mark Zuckerberg, Dustin Moskovitz, and Eduardo Saverin. Facebook has become one of the most popular social networking sites in the world, with over 2.8 billion monthly active users as of December 2020. The company's mission is to connect people and build communities, and it has been successful in achieving this goal by providing a platform for people to share their thoughts, ideas, and experiences.

Facebook has been actively working towards decarbonisation, reducing its carbon footprint, and promoting the use of renewable energy. The company has set a goal to reach net-zero carbon emissions for its entire value chain by 2030. To achieve this goal, Facebook has been investing in renewable energy projects, energy efficiency, and carbon offsets.

One of the ways Facebook is working towards decarbonisation is through the use of corporate power purchase agreements (PPAs). A corporate PPA is a long-term contract between a company and a renewable energy provider to purchase a certain amount of renewable energy at a fixed price. Facebook has signed several corporate PPAs with renewable energy providers to power its data centers and offices. In 2019, Facebook signed a 200 MW corporate PPA with Aviator Wind, a wind energy project in Texas. This PPA will provide renewable energy to power Facebook's data centers in the region.

Facebook is also investing in corporate energy projects to reduce its carbon footprint. In 2018, Facebook announced that it would invest $750 million in a new data center in Alabama that would be powered by 100% renewable energy. The company is also investing in energy-efficient technologies to reduce its energy consumption. Facebook's data centers are designed to be highly energy-efficient, using advanced cooling systems and server technologies that reduce energy consumption.

In addition to its own efforts, Facebook is also working with other companies and organizations to promote the use of renewable energy and decarbonisation. The company is a member of the Renewable Energy Buyers Alliance (REBA), a coalition of companies working to accelerate the transition to renewable energy. Facebook is also a member of the Renewable Energy Buyers Principles, a set of guidelines for companies to follow when purchasing renewable energy.

Facebook's commitment to decarbonisation and renewable energy is not only good for the environment but also good for business. By investing in renewable energy and energy efficiency, Facebook is reducing its energy costs and improving its bottom line. The company is also demonstrating its commitment to sustainability, which is becoming increasingly important to consumers and investors.

In conclusion, Facebook, Inc. is a social networking web company based in the United States of America that is committed to decarbonisation and renewable energy. The company has set a goal to reach net-zero carbon emissions for its entire value chain by 2030 and is investing in renewable energy projects, energy efficiency, and carbon offsets to achieve this goal.
