The charts below summarize the results of the Life Cycle Assessment conducted by PE INTERNATIONAL, Inc. on a 20" walk behind lawn mower with our new 500e Series™ gasoline engine. This site focuses on what we understand to be our primary impacts as an engine and mower manufacturer: energy consumption and greenhouse gas emissions.
Other impacts evaluated include eutrophication (water pollution), acidification (potential to create acid rain) and smog creation potential. All impacts were evaluated along all stages of the life cycle for the entire life of a mower (approximately 5.5 years). It is important to note that the Use and Manufacturing Phases result in the highest environmental impacts.
