Fully TCFD (Task Force on Climate-related Financial Disclosures) aligned, CDP holds the largest
environmental database in the world, and CDP scores are widely used to drive investment andprocurement decisions towards a zero carbon, sustainable and resilient economy.

Sekisui House aims to be a leading company in ESG management based on its global vision to “makehome the happiest place in the world.” We will continue to promote these environmental measuresand contribute to building a sustainable society.

We believe that our selection as an A List company in each of these areas is a recognition of ourefforts in the following areas:Climate Change

We actively participate in international decarbonization initiatives such as SBT (Science BasedTargets), disclosing information and creating a governance structure on climate change risks andopportunities in line with the TCFD framework, and participating in the Global ABC - a global alliancefor decarbonization in the building and construction sector.
Toward the decarbonization of housing, 93% of detached houses built by Sekisui House in Japan in
FY2022 were net zero energy houses (ZEH), and the cumulative number of orders for ZEH rental
housing has now exceeded 25,000 units. We also promote ZEH condominiums for sale, with allcondominiums to meet the criteria of ZEH from 2023 onward.
In the area of decarbonization of the entire supply chain, we work with suppliers to achieve an 80%
supplier SBT-setting rate among major suppliers by 2030.

Forests

In 2007, we established our own Wood Procurement Guidelines and have been promoting ‘FairWood’procurement. Since 2001, we have also been promoting nature-positive urban environments throughour “Gohon-no-ki” (5 Trees) indigenous landscaping project. As a leader in environmentally-friendly
business practices, we will continue to actively disclose information on risks and opportunities in theuse of natural capital in line with the guidelines of the Task Force on Nature-related Financial
Disclosure (TNFD).

Water Security

Our group is mainly engaged in businesses that use little water, such as construction and renovation,
but we take a medium- to long-term perspective on water risk and emphasize the sustainability ofwater resources to respond to the significant impact on our business and related supply chains. At
our production sites specifically, we work to use water efficiently by, for example, using recycledwater in our factories.

◼ Sherry Madera, CEO of CDP, said:“Congratulations to all the companies on CDP’s A List, and those companies that started oraccelerated their journey towards environmental transparency in 2023 – we saw a 24% increase ofdisclosures last year and that trajectory is to be applauded. It is only by laying the groundwork ofdisclosure that companies can show they are serious about the vital part they play in securing a netzero, nature-positive future. Earning a place on the A List is about more than the score. It’s anindication of high quality, complete data that equips companies with a holistic view of theirenvironmental impact, serves as a baseline for transition plans and – crucially – enables them tofollow through on their ambitions. As we move deeper into the Decade of Action, and as CDP
continually raises the bar for what represents environmental leadership, the work of A List companies
is never complete. We look forward to seeing all companies turn their commitments into further andmore meaningful and effective action.”
