Seattle’s port is looking to save money and improve its reputation by becoming more environmentally friendly. Part of this plan is to encourage the use of real estate that is not primarily used for transport.

The Port of Seattle’s new goal is to be the cleanest, greenest and most energy-efficient port in the U.S., said its chief executive, Tay Yoshitani, who believes the move will help the port market itself to its customers and keep in good stead with the community.
