The company has a long history of innovation and has been at the forefront of many technological advancements in the construction industry. Obayashi Corporation operates in the building construction sector and has a strong focus on sustainability and decarbonisation.

The company has recognised the importance of reducing its carbon footprint and has implemented a number of initiatives to achieve this goal. One of the key strategies that Obayashi Corporation has adopted is the use of renewable energy. The company has invested heavily in renewable energy sources such as solar, wind, and geothermal power. This has allowed the company to reduce its reliance on fossil fuels and significantly reduce its carbon emissions.

This system has been adopted by many of the company's projects and has helped to reduce the environmental impact of its construction activities.

Obayashi Corporation has also implemented a waste reduction program that aims to reduce the amount of waste generated by its construction activities. The company has implemented a number of measures to achieve this, including the use of recycled materials and the implementation of waste reduction targets for its projects.

Overall, Obayashi Corporation is a company that is committed to sustainability and decarbonisation. The company has recognised the importance of reducing its carbon footprint and has implemented a number of initiatives to achieve this goal. The company's focus on renewable energy, corporate energy management, corporate PPAs, and sustainable building practices has allowed it to significantly reduce its environmental impact and support the growth of the renewable energy industry.
