United Microelectronics Corporation (UMC) is a leading semiconductor foundry company based in Taiwan. Founded in 1980, the company has grown to become one of the largest semiconductor foundries in the world, providing cutting-edge manufacturing services to a wide range of customers in the electronics industry.

UMC is committed to sustainability and decarbonisation, and has implemented a number of initiatives to reduce its carbon footprint and promote renewable energy. The company has set ambitious targets to reduce its greenhouse gas emissions and increase its use of renewable energy sources, and has made significant progress towards these goals in recent years.

One of UMC's key initiatives in this area is its corporate energy program, which focuses on improving energy efficiency and reducing carbon emissions across all of its operations. The program includes a range of measures such as energy audits, equipment upgrades, and employee training, and has helped UMC to achieve significant reductions in energy consumption and carbon emissions.

Another important aspect of UMC's sustainability strategy is its use of corporate power purchase agreements (PPAs) to support the development of renewable energy projects. Through these agreements, UMC purchases renewable energy directly from developers, helping to drive the growth of the renewable energy sector and reduce its own carbon footprint.

In recent years, UMC has signed a number of corporate PPAs with renewable energy developers in Taiwan, including wind and solar projects. These agreements have helped to increase the share of renewable energy in UMC's energy mix, and have also provided a stable revenue stream for renewable energy developers, enabling them to invest in new projects and expand their operations.

UMC's commitment to sustainability and decarbonisation is not only good for the environment, but also makes good business sense. By reducing its energy consumption and carbon emissions, the company is able to reduce its operating costs and improve its bottom line. In addition, by supporting the growth of the renewable energy sector, UMC is helping to create new business opportunities and drive innovation in the electronics industry.

Overall, UMC is a leading example of a company that is committed to sustainability and decarbonisation, and is taking concrete steps to reduce its carbon footprint and promote renewable energy. Through its corporate energy program and use of corporate PPAs, UMC is helping to drive the transition to a more sustainable and low-carbon future, while also benefiting its own business and the wider economy.
