Rheem’s cumulative carbon dioxide equivalent (CO₂e) emissions avoided figure is calculated based on Greenhouse Gas Protocol’s Technical Guidance for Calculating Scope 3 Emissions (version 1.0) . The calculation compares the product use phase emissions from a growing subset of higher-efficiency products within the Rheem Family of Brands against minimum standard baseline products that provide similar functionality. Electricity, fuel and refrigerant emissions are estimated through each product’s consumption or loss rate using product performance data or standard industry emission factors provided by the US EPA or IPCC databases as applicable by product category. Individual emissions categories are converted to CO₂e units. Emissions avoided per unit of product are scaled according to product sales metrics and cumulated for the estimated time the product has been in use. Equivalencies are then calculated using the US EPA GHG Equivalencies Calculator .

HTPG’s cumulative carbon dioxide equivalent emissions avoided figure is calculated with the same methodology, comparing the product use phase emissions from higher-efficiency HTPG products against minimum standard baseline products that provide similar functionality.
