This metric is based on the Global Reporting Initiative (GRI) G4 Guidelines. It covers one of the requirements of Indicator G4-EN23 - 'Total weight of waste by type and disposal method'. The indicator asks for additional information, not included in this metric. G4-EN23 asks for the total weight of non-hazardous and non-hazardous waste, by the following disposal methods:
Recovery, including energy recovery
Incineration (mass burn)
Deep well injection
Other (to be specified by the organization)
Data on waste generation figures over several years indicates the level of progress the organization has made toward waste reduction efforts. It also indicates potential improvements in process efficiency and productivity. From a financial perspective, the reduction of waste contributes directly to lower costs for materials, processing, and disposal.
Information about the disposal destination reveals the extent to which an organization has managed the balance between disposal options and uneven environmental impacts. For example, land filling and recycling create very different types of environmental impacts and residual effects. Most waste minimization strategies emphasize prioritizing options for reuse, recycling, and then recovery over other disposal options.
This metric is asking for the total amount of waste from the company going to a landfill in metric tonnes:
For WikiRate researchers:
Companies who align reports to GRI’s Sustainability Reporting Standards often include a GRI Content Index or Annex where GRI disclosures, with GRI codes, are listed.
Use the GRI Index, CTRL F, Command F or search button on source preview to search for this index and metrics within the report
Use G4 codes, G3 codes or keywords to quickly find values, keeping in mind that some companies report on the metric using different terms, e.g. G4-EN23 or EN23, total waste or landfill waste
Always check the metric question and methodology for the unit of measure or currency - researchers may need to carry out calculations or conversions before entering the final metric value
Add comments documenting exactly where within the source you found the information (page number) and include details of simple or complex calculations or conversions made to determine the metric value
If you are unable to locate a metric value in a source you can search for additional sources where the data is available and add a new source
Global Reporting Initiative compliance guidance for companies:
To calculate total waste from the organization going to a landfill - G4-EN23-a:
Identify the weight of waste created by the organization’s operations, going to a landfill.
If no weight data are available, estimate the weight using available information on waste density and volume collected, mass balances, or similar information.
Organizations reporting on this disclosure should include describe how the waste disposal method has been determined as comment to the metric value.
