Every home in this 19-hectare Panasonic district has solar and battery storage on a shared grid. The operator reports it hit its 70% CO2 and 30% water targets — the only one who has measured them.
what does this mean?
The strongest source is the operator's or the city's own reporting — an official report, dataset or press release. It grades who did the looking — not how well the project went.

Panasonic-led Fujisawa SST turned a 19-hectare former factory site southwest of Tokyo into a district planned for up to 1,000 households (about 566 built and roughly 2,000 residents by the mid-2020s), where each home has solar panels and battery storage tied to a shared area energy-management system. A decade in, the operator reports it has hit its original environmental targets, though the figures are self-reported, not independently audited.
📊 Impact
Fujisawa SST / Panasonic report a 70% cut in CO2 emissions versus a 1990 baseline and a 30% cut in household water use versus a 2006 equipment-standard baseline, plus a renewable-energy self-consumption rate above 30% — all self-reported by the operator, with no independent audit located.
🎓 Lesson
A privately financed 'sustainable town' can hit ambitious targets on paper — but when the developer that built it is also the only party measuring the results, the numbers are closer to a company report than an independent evaluation.
