No. The modular nature of the standards allows a planner or a supplier to obtain only those standards that are relevant to their operational footprint. For example, a catering company might choose to focus on the Food and Beverage standard, while planners of large city-wide meetings will likely have interest in all nine of the standards.
This modularity also allows planners and suppliers to develop a sustainability plan and roadmap that prioritizes specific impact areas, and to obtain and implement individual standards on an ongoing, incremental basis.
