What tool must be used to generate a climate impact report for ZWR Credit 3?

To generate a climate impact report for ZWR Credit 3, using the US EPA warm model tool is essential because it is specifically designed to calculate the greenhouse gas emissions associated with different waste management practices, particularly focusing on waste reduction and recycling efforts. The warm model tool provides a comprehensive analysis by factoring in various metrics related to waste types and management scenarios, allowing for an accurate measurement of climate impacts based on diversion strategies.

The other tools listed are useful in other contexts but do not serve the same purpose for ZWR Credit 3. For instance, the US EPA energy calculator primarily focuses on energy use and savings, the emissions data tracker is more geared towards broader tracking of emissions rather than specific waste impacts, and the waste audit tool helps to evaluate waste generation and composition without directly calculating the associated climate impacts. Therefore, the warm model tool is the most pertinent tool in the context of generating a climate impact report for this specific credit.
