Set limits Require planning/action Set schedules Define goal that reflects a full range of considerations Ensure that full range of issues is analyzed in planning process Phase the schedule – to allow piloting/testing of new technologies/approaches (so plan can evolve over time) Include mechanism to substitute sustainable approaches identified in the future
