Founded in 2006, the company is headquartered in Tokyo, Japan, and has a workforce of over 200,000 employees. Japan Post Holdings is one of the largest companies in Japan and is involved in a wide range of businesses, including postal services, banking, and insurance.

In recent years, Japan Post Holdings has been focusing on decarbonisation and corporate energy initiatives. The company has set a goal to reduce its greenhouse gas emissions by 30% by 2030, compared to its 2013 levels. To achieve this goal, Japan Post Holdings has been investing in renewable energy and energy-efficient technologies.

One of the key initiatives undertaken by Japan Post Holdings is the Corporate Power Purchase Agreement (PPA). Corporate PPAs are long-term contracts between a company and a renewable energy provider, which allows the company to purchase renewable energy directly from the provider. This helps to reduce the company's carbon footprint and also provides a stable source of renewable energy.

In 2019, Japan Post Holdings signed a corporate PPA with a solar power plant in Miyagi Prefecture. The plant has a capacity of 2.6MW and is expected to generate around 3,000MWh of electricity per year. This is equivalent to the electricity consumption of around 1,000 households. The PPA will help Japan Post Holdings to reduce its greenhouse gas emissions by around 1,700 tons per year.

Japan Post Holdings has also been investing in renewable energy projects. In 2018, the company announced that it would invest in a 2.6MW solar power plant in Fukushima Prefecture. The plant is expected to generate around 3,000MWh of electricity per year, which is equivalent to the electricity consumption of around 1,000 households. The investment in the solar power plant is part of Japan Post Holdings' efforts to promote renewable energy and reduce its carbon footprint.

In addition to its renewable energy initiatives, Japan Post Holdings has also been focusing on energy efficiency. The company has been implementing various measures to reduce its energy consumption, such as the installation of LED lighting and the use of energy-efficient equipment. Japan Post Holdings has also been promoting energy-saving practices among its employees, such as turning off lights and computers when not in use.

Japan Post Holdings' commitment to decarbonisation and corporate energy initiatives has been recognised by various organisations.
