What you most probably mean, is "Nachhaltigkeit", which is the word used in Germany for anything having to to with "long-term caring about the world/nature/environment". Other forms are "nachhaltig denken" or "nachhaltig handeln" (to think or act long-term). It´s used everywhere, everybody understands that here. All other words are too abstract and never used in real life.
