Briggs & Stratton is using Life Cycle Assessment (LCA) to better understand the environmental impacts of our products so that we can identify and execute improvements that benefit our customers, consumers and shareholders.

Raw Materials Extraction and Processing

A mower begins when metals and petroleum are extracted from the earth to process into raw materials for our finished products. We work to reduce the burden on this phase by using recycled content materials whenever possible, thus minimizing the amount of materials that need to be newly mined from the earth.


Briggs & Stratton purchases raw materials and intermediate parts and manufactures the engine and sometimes the finished mower. We are always improving the efficiency of our operations to reduce energy, water and other emissions as part of our Environmental Management System.


Briggs & Stratton ships engines to its walk-behind lawn mower factories or to other Original Equipment Manufacturers (OEMs). Finished mower goods from Briggs & Stratton's own manufacturing facilities are shipped directly to retailers, dealers or sold online.


Consumers purchase a mower from a retailer or dealer, as well as gasoline to fuel the mower. Over the course of the average 5.5 year life span of a mower*, oil is replaced and recycled. Consumer use of gasoline is typically the most burdensome aspect of the mower life cycle.

*Based on 125 hours of operation – Mowing a 1/5 acre lawn, 30 times per year for 45 minutes per cut.


The transportation phase also includes the movement of the end-of-life product to the appropriate disposal facility. When displaying transportation data, keep in mind that transportation of raw materials, finished goods and end-of-life products are combined to represent this phase.


At the end of its useful life, the mower is transported, either by the consumer or another third party, to be recycled at a scrap metal facility.
