Use Phase

Typical of various powered products, the environmental impacts of mowers primarily occur through the consumption of gasoline. For this mower/engine combination, roughly 60-70% (83 pounds CO2 equivalent per year of the product's life) of the product's Global Warming Potential and Primary Energy Demand results from gasoline consumption during the use phase.

 

Fuel Comparison The total energy consumption and Global Warming Potential (aka 'carbon footprint') of an entire year's worth of use of your engine, (at an average fuel consumption of 5 gallons per year), is roughly equivalent to driving 135 miles* – once. In total, your lawn mower uses about 1% of the fuel of the average North American automobile over the course of a year, which means the total carbon footprint of mowing your lawn is just 1%** of your annual driving footprint.

 

CO2 Emissions Put in other terms, it would take 300 Briggs & Stratton mowers to equal the same greenhouse gas emissions as the energy used in one US home*** annually.

 

 

While this impact might be small in comparison to your total household carbon footprint (Curious about what yours might be? Calculate your own.), it is our product's biggest impact, so we work hard to reduce it. Briggs & Stratton has reduced smog emissions from its engines by 75% since 1995, and we are always working to improve the fuel efficiency of the engine as well, while improving performance. Briggs & Stratton is improving fuel efficiency with the introduction of new overhead valve (OHV) engines. 

You can do your part: Maintenance tune-ups of your mower help extend the life of your current mower, improve the quality of your grass cut, and reduce the all-important emissions and fuel consumption during use. Keeping your mower maintained also extends the life, delaying the purchase of a new engine, which also delays the environmental impacts associated with the manufacturing of a new engine. It may even save you some cash. Check out our maintenance How-Tos, or visit an authorized Briggs & Stratton dealer.

You can also reduce the impact of your engine by recycling your oil through Briggs & Stratton's national oil recycling program managed in collaboration with an authorized Briggs & Stratton dealer. Learn more information about this recycling program.
