The National Center for Appropriate Technology (NCAT) is an American organization headquartered in Butte, Montana, that is dedicated to appropriate technology and sustainability. Projects specifically deal with sustainable energy, sustainable agriculture and food, sustainable living, farm energy, and climate change.
