Reduce CO₂ emissions to build a low-carbon society	Reduce total CO₂ emissions (Scope I, II, and III)			CO₂ emissions per sales (t-CO₂/ ¥100 million)	344.5 *1	▲20%	280.2 (▲18.7%)	258.2 (▲25%)		Adoption of 120 mm thick high-insulation panels has risen, due to the success of ZEH promotion, increasing CO₂ emissions at each stage of production, transportation and construction. But the CO₂ reduction of ZEH more than offset this rise, leading to total CO₂ emissions of 258 tons per 100 million yen sales for a year-on-year decrease of 8%. We greatly exceeded our target in the remodeling business, thanks to a larger number of projects with significant CO₂ reduction by such measures as improved insulation.
		Reduce CO₂ emissions at residential stage		CO₂ emissions per home (t-CO₂/ home)	6.03 *2	▲40%	4.68 (▲22.4%)	4.61 (▲23.5%)
			ZEH supply rate for new single-family homes	ZEH supply rate	7.5%	60%	22%	31%
			Energy conservation for new multi-dwelling units	CO₂ emissions per home (kg-CO₂/ home･year)	1,912	▲10%	1,774 (▲7.2%)	1,779 (▲7.0%)
		Reduce CO₂ emissions through energy-saving renovation of existing homes		Annual amount of CO₂ reduction (t-CO₂/ year)	1,371	1.3	1,143 (0.83)	2,831 (2.06)
		Reduce CO₂ emissions at production, transportation, and construction stages		CO₂ emissions per square meter (kg-CO₂/m²)	37.87	▲3%	37.3 (▲1.5%)	38.25 (1.0%)
		Reduce CO₂ emissions from office activities		CO₂ emissions per capita (kg-CO₂/ capita)	721	▲5%	627 (▲13.0%)	885 (22.7%)
Reduce waste and effectively use resources to build a recycling-oriented society	Reduce waste generated at factory production stage			Volume generated per square meter (kg/m²)	4.45	▲3%	4.59 (▲3.1%)	4.15 (▲6.7%)		At the factory production stage, we steadily reduced the volume of waste through streamlined production and progress in recycling. At new home construction sites, the volume of waste per floor area increased slightly, due to a decrease in large-scale apartment projects and an increase in projects building homes on small lots in urban areas. Nevertheless, the availability of long-life quality housing improved for both single-family homes and multi-dwelling units. Such housing extends buildings’ longevity and minimizes the need for demolition work, which generates large amounts of waste.
	Reduce waste generated during construction for new homes (average of wooden and steel frame homes)				23.02	▲10%	22.52 (▲2.2%)	23.73 (3.1%)
	Reduce waste and effectively use resources by expanding long-life quality housing and extending building longevity			Product ratio	36% (3,820)	60%	52.6% *3 (4,116)	55.6% (4,087)
		Promote long-life quality of new single-family homes		Product ratio	50.4% (3,803)	80%	60.3% *3 (4,105)	60.8% (4,076)
		Promote long-life quality of new multi-dwelling units		Product ratio	0.6% (17)	5%	1.0% *3 (11)	1.7% (11)
	Reduce waste and effectively use resources by increasing distribution of existing homes			Sales of existing home business (¥100 million)	37	50	37.9	35.4
Emphasize biodiversity to build a society in harmony with nature	Promote procurement of certified lumber			Lumber procurement rate	81% (Structural material)	Expand target to non-structural materials (target value unknown)	80% (Structural material)	80% (Structural material)		The procurement rate for certified lumber remains high. The amount of certified environmentally friendly housing,particularly subdivision homes, was up from last year. This applies to homes that satisfy such criteria as the greening rate.
	Promote environmentally symbiotic housing			Number of approved homes	271	500	200	254
Establish safe, comfortable,healthy living environments	Reduce use of chemical substances subject to PRTR system at production stage			Usage per square meter (g/m²)	15.7	▲10%	14.1 (▲10.2%)	18.92 (20.5%)		The use of adhesives increased at factories producing components, due to a change in specifications for fixture materials. But safety was maintained at all factories with environmental ISO certification by carefully controlling chemical substances. We added the M-Smart (Wellness) City concept to three additional locations in Japan, including a condominium complex in Urayasu that offers senior care services.
	Reduce volume of VOCs emitted in indoor environments			Compliance rate to VOC standards	95%	100%	95%	95%
	Promote development of M-Smart (Wellness) City			Number of developed properties (project)	2 (6, in total)	Increase annually	4 (12, in total)	3 (15, in total)
