GRESB waste performance indicator data sources
Review a table that outlines how IBM® Envizi ESG Suite assigns corresponding data source values to GRESB waste performance indicator fields in the GRESB Asset Summary.
Waste reporting is the most straightforward of the performance indicators. The same logic applies for reporting activity data, but most users find it easiest to avoid using tags and use only location settings if all waste production is considered nonhazardous.
For the water performance indicator, the waste disposal routes are recorded in the GRESB location settings, which can either be captured in a form at the location level or by using grid capture at the group level.

| Whole Building - Non-hazardous waste - Weight (tonne) | All waste production in the related building space, within the related data type category of
waste or recycled waste. |
| Whole Building - Data coverage - (%) |
Note: Special condition: If waste data is not available, GRESB requires that zero coverage is
shown.
Calculated field: Count number of months of data available divided by 12 * 100%. If no data, then the value is zero. |
| Proportion of waste by disposal route - Landfill - (%) | Percentage is taken from GRESB Location Settings. |
| Proportion of waste by disposal route - Incineration - (%) | Percentage is taken from GRESB Location Settings. |
| Proportion of waste by disposal route - Reuse - (%) | Percentage is taken from GRESB Location Settings. |
| Proportion of waste by disposal route - Waste to energy - (%) | Percentage is taken from GRESB Location Settings. |
| Proportion of waste by disposal route - Recycling - (%) | Percentage is taken from GRESB Location Settings. |
| Proportion of waste by disposal route - Other / Unknown - (%) | Percentage is taken from GRESB Location Settings. |
