Projects that do divert 100% of landscaping waste have the easiest time showing compliance, and it’s usually an attainable goal. If you do not address 100% of waste through diversion, you’ll need to track the total quantity of green waste generated by landscaping activities and the quantity diverted from landfill disposal. Use these values to determine the overall percentage of waste diverted. You can quantify green waste either by weight or by volume; whichever is easiest for building staff or vendors to track consistently. Submit a log of this information to demonstrate your building’s performance. You are not required to submit third-party documentation to verify waste quantities, however, if this type of documentation is available you may submit it to support credit achievement.
