Sustainability management

Establishing key challenges and indicators through engagement with stakeholders

Reviewing Sustainability Challenges

To address changing social conditions, such as the SDGs and carbon neutrality, Misawa Homes has reviewed its commitment to sustainability. As a result, it has selected 24 new sustainability challenges to take on.
We surveyed the expectations and assessments of 2,306 stakeholders, including homeowners, business partners, and employees.

Review of Key Sustainability Challenges

Select sustainability challenges

To identify the most vital sustainability challenges for Misawa Homes, we looked at our sustainability actions and selected 24 challenges in eight categories, based on the SDGs, various questionnaire surveys, and issues that other companies in the industry are dealing with.

Setting Key Sustainability Challenges

We sent questionnaires to 2,306 stakeholders to gauge their expectations and assessments of the 24 selected challenges.
To set our Key Sustainability Challenges, we identified the 24 challenges that stakeholders had the highest expectations of and considered most important.

Defining Key Sustainability
Indicators for the Key Sustainability Challenges

By positioning the critical sustainability issues as vital challenges for the company, defining key indicators for individual cases, and calculating our performance every year, we can monitor our progress over time and “visualize” our sustainability actions.

FY2018 Results FY2019 Results

We learned that worsening global warming -- increasing incidence of typhoons, intense torrential rains, and other devastating natural disasters -- and a growing interest in the problem of plastic waste, have led to high expectations for ZEH, waste reduction, and disaster-resistant, highly durable housing that people can live in for a long time.
