Samsung Electronics made a significant commitment to renewable energy. In a statement on its website, the tech giant said it was planning to use 100 percent renewable energy at its factories, office buildings and operational facilities in Europe, China and the U.S. by 2020.

The business is set to install around 42,000 meters squared of solar panels at its headquarters in Suwon, South Korea, and will also add solar arrays and geothermal power generation facilities at its campuses in Pyeongtaek and Hwaseong, according to CNBC.

Additionally, Samsung said it would work with its top 100 partner companies to assist them in setting their own renewable energy targets, in partnership with the CDP’s (formerly the Carbon Disclosure Project) supply chain program. Samsung said it intended to join the program next year.

The CDP’s program collaborates with more than 100 purchasing organizations and over 10,000 suppliers to both identify and manage deforestation, climate change and water related risks. “Samsung Electronics is fulfilling its duty as a corporate citizen by expanding and supporting the use of renewable energy,” Won Kyong Kim, Samsung Electronics’ executive vice president and head of global public affairs, said. “As demonstrated by our expanded commitment, we are focused on protecting our planet and are doing our part as a global environmental steward.”
