Long-Term Environmental Vision
“Challenge ZERO 2055”
The Daiwa House Group aims to realize a sustainable society as a Group that cocreates value for individuals, communities, and people’s lifestyles and tries to make “zero” environmental impacts within our Group, globally, and through supply chains.
Our Group formulated the long-term environmental vision “Challenge ZERO 2055” in fiscal 2016, focusing on in the runup to our 100th anniversary in 2055*. With the formulation of the Endless Green Program in fiscal 2026, we revised the milestone year for our Long-Term Environmental Vision from 2030 to 2035. Aiming to help build a sustainable society, we are taking on the challenge of bringing environmental impact to zero across four priority environmental themes — carbon neutrality, nature positivity, circular economy, and water circularity — through three phases: procurement, business activities, and products and services.
* With regard to carbon neutrality, we have set the year 2050 in light of social demands.
Four environmental priority themes
Phase
Procurement
- Resource extraction
- Transport of raw materials
- Material production
- Material transport
Business activities
- Office work / Vehicles
- Factories / Logistics
- Construction / Renovation
- Demolition
- Operation of office buildings
Products and services
- Single-family /
Rental housing - Condominiums
- Renovations
- Commercial facilities / Office buildings
- Environmental energy
Carbon neutrality
(Mitigating and adapting to climate change)
Milestone for 2035
We aim to reduce greenhouse gases (GHG) emissions across the entire value chain by 35% (vs. FY2020).
- By making new buildings ZEH- and ZEB-compliant and installing solar power generation systems, we aim to reduce GHG emissions from newly constructed buildings in the habitation and usage stage by 50% (vs. FY2020).
- Through energy-efficient and energy-generating renovations of existing buildings, we aim to reduce primary energy consumption to a level equivalent to ZEH and ZEB standards.
- We supply renewable energy to society through businesses spanning the design and construction of renewable energy generation facilities to power generation and retail.
- By mitigating the damage from increasingly frequent water disasters and providing products and services that allow people to stay healthy and comfortable even in high temperatures, we aim to help build a society that can adapt to rising temperatures.
- Through energy conservation, electrification, and the shift to renewable electricity, we aim to reduce greenhouse gas emissions from our own direct operations by 80% (vs. FY2020).
- We implement measures that place the highest priority on protecting the lives and health of workers at construction and production sites, thereby curbing declines in productivity and workforce numbers.
- By collaborating with suppliers on energy conservation, renewable energy, and low-carbon building materials, we aim to reduce greenhouse gas emissions at the procurement stage by 37.5% (vs. FY2020).
Our Vision for 2055*
To achieve carbon neutrality, we aim to bring greenhouse gases emissions across the entire value chain to zero by taking thorough energy-efficiency measures and using renewable energy.
In addition, by taking adaptation measures to avoid or minimize the negative impacts of climate change, we aim to conduct business activities that are resilient to climate change risks and help build a safe, secure society.
* Carbon neutrality achievement year: 2050
Nature positive
(Halting and reversing nature loss)
Milestone for 2035
- In our housing- and building-related businesses, we improve both the quantity and quality of green spaces with consideration for biodiversity, aiming for an Area of ecosystem-considerate greening of at least 3 million m2 (cumulative from FY2022).
- For development projects above a certain scale, we aim to achieve net gain (a shift to positive impact) through development that harmonizes with the local natural environment based on our own development standards.
- We will complete biodiversity assessments of our direct operational sites and promote risk response and conservation activities at sites that are important to ecosystems.
- In our housing-, building-, and power-generation-related businesses, we conduct due diligence such as verifying the origins of timber, steel, and concrete, and we minimize the procurement risks of high-impact commodities (HICs)* and contribute to the recovery of natural ecosystems.
Our Vision for 2055
To help build a world of harmonious coexistence with nature, we aim for zero conversion of natural ecosystems across the entire value chain — through ecosystem-conscious procurement of timber and raw materials, community development in harmony with the local natural environment, and landscape engagement at procurement and business-activity sites.
* High-impact commodity: a raw material considered to have a large impact on nature.
Circular economy
(Fostering economic activity by pursuing the cycle of Create, Use, and Revitalize)
Milestone for 2035
- Create
In new construction, we actively adopt recycled materials and non-depletable resources for principal building materials to reduce the use of virgin resources, and we aim to ensure our buildings are easy to renovate and demolish so as to facilitate the future reuse of by-products.
- Use
For existing buildings, we will extend their service life through regular inspections, extended warranties, maintenance work that preserves durability, and the expansion of our buyback-and-resale business, thereby reducing the input of new resources. We also aim to foster a market in which such buildings are appropriately valued and traded.
- Revitalize
In the new construction, renovation, and demolition of buildings, we aim for zero incineration and zero landfill disposal through the reuse and recycling of by-products.
Our Vision for 2055
To help build a circular economy, we work to minimize the new input and consumption of depletable resources by extending the service life of buildings and reusing resources from existing buildings, and we aim to contribute to a society in which buildings designed for such resource circulation are appropriately valued and traded.
Water circularity
(Securing water resources and addressing water disasters)
Milestone for 2035
- We provide products with low impact on the water environment and aim to create highly resilient buildings that do not overly depend on water supply lines.
- We aim to reduce water usage in accordance with local water-stress levels and to conserve local water resources.
- We minimize the impact of water disasters on our business and enhance the resilience of our operations.
- In our housing-, building-, and power-generation-related businesses, we conduct due diligence such as verifying the origins of timber, steel, and concrete, and we aim to minimize the risks of water-quantity and water-quality pollution associated with high-impact commodities (HICs).*
- In our housing- and building-related businesses, we assess the water-related risks of key business partners and aim to minimize procurement risks.
Our Vision for 2055
Across the entire value chain, we strive to reduce water use and promote its circular use, conserve the water environment, and contribute to the sustainable use of water resources.
* High-impact commodity: a raw material considered to have a large impact on nature.
