Calculations based on EPA Smartway Publication EPA420-F-04-005 issued by the Office of Transportation and Air Quality. Weight savings based on 27 pound difference between an iGPS plastic pallet and typical multi-use wood pallet. Note: This calculator focuses exclusively on the environmental benefits resulting from the lighter weight of iGPS' all-plastic pallet. However, even more greenhouse gases are reduced when switching to iGPS since iGPS pallets eliminate the deforestation impacts of wood pallets. Research shows that nearly 40% of all hard wood harvested in the U.S. is used for wood pallets, and it is well documented that deforestation is another major contributor to global climate change.
