The Daiwa House Group aims to realize a sustainable society as a group that co-creates value for individuals, communities, and 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 2055, which marks the 100th anniversary of the foundation of Daiwa House Industry. As a "group that co-creates value for individuals, communities, and lifestyles," the Group management vision, we aim to realize a sustainable society and try to create zero environmental impacts through three stages (procurement, business activities, and products and services) with four environmental priority themes in mind (slowing and adapting to climate change, harmony with the natural environment, conservation of natural and water resources, and prevention of chemical pollution).
Slowing and adapting to climate change (Prevention of global warming / energy)
|Challenge1||We aim for zero CO2 emissions throughout the product life cycle through uncompromising pursuit of energy saving and utilization of renewable energy in order to achieve a carbon-free society.|
By achieving ZEH and ZEB for average new houses and buildings (by 2025 for single-family houses, by 2030 for buildings), we aim to reduce greenhouse gas emissions (per area) from houses and buildings in use by 30% by 2030 from the fiscal 2015 levels. At the same time, we are going to promote the construction of zero energy towns through renewable energy-based power generation and low-carbon electricity supply. [SBT]
(SBT: Science Based Targets)
We aim to reduce greenhouse gas emissions in all facilities and all business processes (per sales unit) by 45% by 2030 and by 70% by 2055 from the fiscal 2015 levels. [SBT]
- By further promoting energy saving for existing facilities and achieving ZEB for facilities to be newly constructed, we aim to increase the Groupwide energy efficiency (sales unit per consumed energy) by half by 2030 and double it by 2040 from the fiscal 2015 levels. [EP100]
- We aim to expand renewable energy and raise the ratio of renewable energy-based power generation (including sales of electricity) to the Groupwide use of electricity up to 100% by 2030 and fully cover it with renewable energy by 2040. [RE100]
（EP100 : Energy Productibity, RE100 : Renewable Energy）
We aim to decarbonize our supply chain, in the process of the initiatives we are taking jointly with 90% of our main suppliers, by sharing the Paris Agreement-based greenhouse gas emissions reduction target by 2025. [SBT]
Harmony with the natural environment (Preservation of biodiversity)
|Challenge2||In order to preserve and improve our natural capital, our Group shall achieve no net loss of green space by ensuring zero deforestation through material procurement and by developing communities filled with greenery.|
Minimize the loss of our natural capital associated with development and improve the quantity and quality of green space by collaborating with our customers when we construct housing, buildings, and towns. Achieve the objective of no net loss* of green space.
* The concept of offsetting a loss of biodiversity in one location by increasing biodiversity in another location, resulting in no net impact.
Regarding the building materials used to construct houses and buildings, we are focusing on zero deforestation associated with wood procurement by 2030 and zero deforestation associated with material procurement across all our business by 2055.
Conservation of natural resources (Longer durability / Waste reduction / Water resource conservation)
|Challenge3||In a bid to realize a resource-recycling society, we aim for sustainable utilization of resources through an increase in durability of housing and buildings, zero waste emissions, and a sound water cycle.|
We aim to extend the durability and increase the variability of our new houses and buildings. In addition, in order to have property asset values of high-quality houses and buildings maintained for a long term, we are going to renovate or remodel existing houses and buildings in an optimal way and create the market in which they will be appropriately evaluated and circulated.
We aim to realize zero waste emissions (recycling and reuse) throughout the life cycle of houses and buildings by 2030 and through the other businesses by 2055.
In a bid to minimize (ultimately to zero) water risk, we are going to reduce water consumption and manage waste water thoroughly throughout the life cycle.
Prevention of chemical pollution
|Challenge4||We shall institute appropriate management of chemical substances throughout the life cycle of houses and buildings to minimize the risk (ultimately to zero) of adverse impacts on the health of people and ecosystems.|
Identify the risk of chemical substances in the life cycle of houses and buildings, employ substitutes, promote reduced use of toxic chemicals, and appropriately manage chemical substances with using a precautionary approach. Continue to minimize the risk (ultimately to zero).
Continue working on minimization of the risk (ultimately to zero) through strict management of soil contamination risk, including conducting investigations and applying countermeasures from initial land transaction through the construction process, employing the same standard to the company's own land holdings.
