Environmental Declaration
Misawa Homes has announced a “New Environment Declaration” in 1997 as an environmental initiative. Since then, based on that declaration, we have developed a variety of environmental activities.

Carbon neutral promotion structure
Toward Carbon Neutrality in 2050
2030 Intermediate Goal: 50% Reduction in CO2 Emissions (relative to FY2020)
Ever since the Misawa Homes Group was founded, we have strived to develop the most advanced technologies based on original ideas, always aiming at making world-first, Japan-first, or industry-first breakthroughs.In a wide range of business activities, we have deployed these technologies to solve social and environmental problems.
The Japanese government declared in October 2020 that it would aim to become carbon neutral by 2050. In Japan, the consumer sector*1 accounts for about 30% of final energy consumption, raising the need and expectation for the housing industry to reduce consumption from both hardware and software perspectives. The Misawa Homes Group promotes CO2 emission reduction through various business activities to achieve carbon neutrality by 2050 via housing stock business, community development business, and the promotion of ZEH*2 and LCCM®*3 in new-house business.
*1 Including the household and business sectors
*2 Zero Energy House
*3 Life Cycle Carbon Minus housing LCCM is a registered trademark of the Institute for Built Environment and Carbon Neutral for SDGs (IBECs).
It refers to a decarbonized house that achieves negative CO2 emissions across the entire life cycle from construction, to occupancy, to demolition.

Targets and Initiatives for Carbon Neutrality
1Promotion of ZEH
Ratio of ZEH to all new detached homes
To promote homes that contribute to carbon neutrality, in April 2023, we at Misawa Homes launched SMART STYLE Roomie, a standardized ZEH detached home. To promote ZEH, in April 2024, we added the "large roof type" and "single-story house type" to its lineup to support LCCM®, which is a future standard higher than ZEH.
Ratio of ZEH-M (Nearly ZEH-M or higher) to all apartment buildings
Our efforts previously focused on detached homes. However, since the declaration of carbon neutrality goals, we have gradually gained some results even from low-rise apartment houses introducing ZEH-M and Nearly ZEH-M. Going forward, we will further strengthen the initiatives.
2Introduction of Renewable Energy (RE100)
Renewable energy ratio
3CO2 Emission Reduction in Business Activities
- Reduction in office activities
- Reduction in factory production
- Reduction in construction sites
4Contribution to Greenhouse Gas Emission Reduction
Contribution to reduction through Eco Reform promotion
Reduction by Eco Reform
Eco Reform reduces CO2 emissions from households by improving window insulation, replacing with energy-saving products such as high-efficiency water heaters and Ene Farm, and renovating such as installation of a solar energy generation panel. The number of insulation or energy-saving renovations is expected to help progress toward carbon neutrality.
