What is one example of proof that TRUE requests for waste metrics?

The correct choice illustrates a concrete method of demonstrating TRUE's request for waste metrics through the inclusion of diversion rates and supporting evidence from waste haulers. This is critical because diversion rates serve as key performance indicators reflecting how much waste is being diverted from landfills through recycling, composting, or other waste management strategies. The data supplied by waste haulers corroborates these rates, providing an additional level of verification that can support claims about waste management practices.

In sustainability reporting and waste management practices, verifying metrics with reliable data sources is essential to creating a transparent and accurate representation of a facility's waste performance. By confirming the diversion rates through external validation, stakeholders can have confidence in the reported numbers and make informed decisions about their waste management strategies.

The other choices, while related to waste management, do not directly serve as proof of how waste metrics are measured and reported. For instance, while documentation of hazardous waste disposal methods provides important safety and regulatory information, it does not reflect the broader metrics or performance indicators that TRUE is interested in. The list of stakeholders involved in the process may show who is responsible for waste management but doesn't quantify or provide evidence of actual waste practices. Estimates of future waste generation could be useful for planning purposes, but they do not serve as a
