Sekisui House Ltd announced Oct 20, 2017, that it has joined the "RE100" initiative, which is aimed at using only renewable energy-derived electricity in business activities.

Sekisui House is the second Japanese company that has announced the participation in the RE100, following Ricoh Co Ltd. And it is the first Japanese company in the construction industry that has made such an announcement.

Sekisui House made a "declaration to abandon carbonization" in 2008, aiming to achieve the goal by 2050. The amount of power that the company consumed for its business activities in fiscal 2016 was 120,533MWh. By joining the RE100, it aims to go forward with the abandonment of carbonization in regard to power consumed in its business activities and increase the ratio of renewable energy to 50% by 2030 and 100% by 2040.

Also, Sekisui House has been making efforts to spread the use of zero net energy houses (ZEH) and has so far supplied solar power generation systems with a total output exceeding 650MW. As the feed-in tariff (FIT) policy for residential systems starts to end in fiscal 2019, the company plans to create advantages to house owners by purchasing surplus electricity generated by residential solar power generation systems.

The RE100 is an international initiative having a goal of "100% renewable energy." Companies in a wide variety of industries including IT and auto manufacturing have participated in it, and their total revenue is about US$2.5 trillion. They include companies ranked in Global Fotune 500. The RE100 is giving strong messages to policymakers and investors to make them promote the shift to a low-carbon society.

The RE100 is part of "We Mean Business," which is led by Climate Group in partnership with CDP.
