All but one of the town's 15 lodgings qualify as green hotels. Though its population barely exceeds 3,300, enough visitors flow into this picturesque town from surrounding ski areas to keep occupancy high. The greening grew out of the Chester Innkeepers Association, a mostly social organization founded in 1984. Jo-Ann Jorgensen joined it in 2005 after moving from Denmark to open the Park Light Inn. She weatherized, insulated, installed low-flow toilets and showerheads, dispensed with bottled water and individually packaged toiletries, introduced a towel-reuse program, and more. One of the biggest paybacks came early: Her heating bill dropped by 40 percent, even though she had added square footage. And her enthusiasm proved infectious. Within two years, the association voted unanimously to require green hotel status as a condition for membership.
