Track or estimate variations in materials management that occur outside the reporting period, such as seasonal collection or intermittent waste streams.
Calculate waste diversion by tracking the amount of materials (by weight) diverted from landfills and incineration. For diverted materials, specify the diversion method (reduce, reuse, recycle, compost, etc.). If material quantities are estimated, provide the methodology and/or source references used to make calculations. If actual weights are unavailable for certain material types or hauling methods, volume-to-weight conversion average values can be used.
To calculate the overall diversion rate, divide the weight of materials diverted by the total weight of materials generated for the same reporting period. Account for seasonal collection or intermittent waste streams within the calculations. See Equation 1 for the waste diversion calculation:

REQUIREMENTS EXPLAINED
This credit rewards projects for waste reduction and diverting materials from landfills or incineration. To do this, projects will measure, track, and report the amount of waste generated at the project and the amount of waste diverted from landfills and incineration facilities. Measuring a building’s waste performance and understanding the effectiveness of the waste management practices can help facility managers optimize solutions for zero waste operations.
Projects earn points for increased levels of diversion compared to the total amount of waste generated from ongoing building operations and maintenance.
Scope of Materials
Materials are defined as solid, non-hazardous discards that are generated within the project boundary. This includes materials produced during regular operations as well as during episodic activities (construction and demolition, special events, etc.). Materials generated and managed by tenants must be included.
