The Environmental Benefits of Electric Mowers
Why Electric: The Environmental Benefits
- Low Noise: As demonstrated in this video, Mean Green Electric Lawn Mowers produce about 1/3 the sound intensity of conventional gas or diesel mowers of similar horsepower.
- Decreased Fossil Fuel Use: Traditional commercial gas/diesel mowers typically burn 1 to 2 gallons of gas or diesel per hour which means that for every commercial gas/diesel lawn mower that’s replaced with an electric mower in the New England region, fossil fuel use can be reduced by approximately 1,440 to 1,920 gallons per year (assuming 6 to 8 hours/day, 5 days/week, 24 weeks/year). Depending on the type and horsepower rating of a mower used by a homeowner mowing 1 to 2 hours a week (for 24 weeks), anywhere from 5 to over 50 gallons of gas or diesel could be saved per year.
- CO2 Reduction: Since every gallon of gas/diesel burned emits an average of about 22 lbs. of CO2 (includes the carbon in the gas/diesel plus the oxygen used during combustion) and because electric mowers have zero CO2 emissions, for every commercial gas/diesel lawn mower that’s replaced with an electric mower in the New England region, CO2 emissions could be reduced by approximately 31,680 to 42,240 lbs (approx. 16 to 21 tons), less the amount of C02 emissions generated by the production of the electricity used, which increasingly is being generated from renewable sources such as sun, wind, and hydro. And therefore, for every 100 commercial gas/diesel lawn mowers that are replaced with electric mowers in the New England region, CO2 emissions will be reduced by approximately 1,600 to 2,100 tons, (again, less the amount of C02 emissions generated by the production of the electricity used).
- Air Pollution Reduction: Because conventional gas and diesel lawn mowers have minimal emission controls, they are widely recognized as a major source of smog-forming air pollution. In-fact, according to one EPA study, for every 1 hp rating, a typical lawn mower emits the equivalent air pollution of 3.67 automobiles driving at 55 mph. Therefore, replacing a 36 hp diesel or gas mower with a 36 hp electric mower, the equivalent emissions of 132 cars driving at 55 mph could be avoided per hour of mowing. Similarly, the equivalent emissions of 88 cars could be avoided for every 24 hp gas/diesel mower that’s replaced with a 24 hp electric mower, and the equivalent emissions of 20 cars could be avoided for every 5.5 hp gas/diesel mower that’s replaced with a 5.5 hp electric mower. Clearly, considering the hundreds of thousands of conventional lawn mowers operating in New England, there exists enormous potential to improve regional air quality throughout the lawn mowing season, which is both when “High Smog Alert” conditions are most frequent AND when many people are outdoors recreating.
- Increased Use of Renewable Energy: With ever-expanding solar and wind energy capacity in New England, there’s an ever-increasing potential for the electricity used to recharge batteries to come from renewable sources.
- Support of Local Economies: For every dollar not spent on imported gas and diesel fuel, more dollars remain to support New England’s local economy.

Lawn Mower Emissions Facts
According to an EPA study, one 3hp lawn mower emits the same air pollution as 11 cars driving at 55 mph. Each additional HP is calculated with a linear use equation. Each 1 HP from a lawn mower = 3.67 CARS AT 55 MPH EMISSIONS.
COMMERCIAL ZTR GAS MOWER
- 24 HP COMMERCIAL ZTR MOWER = 88 CARS AT 55 MPH EMISSIONS (= 4,840 car miles each hour)
- 24 HP ZTR MOWER @ 3.5 HRS (NATIONAL AVERAGE/DAY) = 308 CARS AT 55 MPH/DAY = 16,940 MILES CAR EMISSIONS/DAY
- 24 HP ZTR USED 350 HOURS/YEAR = 1,694,000 CAR MILES OF EMISSIONS/YEAR
- 1,694,000/12,000 MILES (AVERAGE ANNUAL CAR MILES) = 141 CAR EMISSIONS PER YEAR FOR EACH COMMERCIAL ZTR MOWER
RESIDENTIAL GAS RIDING TRACTOR MOWER
- 18 HP RIDING MOWER = 66 CARS AT 55 MPH EMISSIONS (= 3,633 car miles each hour)
- 18 HP RIDING MOWER @ 1.5 HRS (NATIONAL AVERAGE/WEEK) = 99 CARS AT 55 MPH/WEEK = 5,445 MILES CAR EMISSIONS/WEEK
- 18 HP RIDING MOWER USED 50 HOURS/YEAR = 181,650 CAR MILES OF EMISSIONS/YEAR
- 181,650/12,000 MILES (AVERAGE ANNUAL CAR MILES) = 15 CAR EMISSIONS PER YEAR FOR EACH RESIDENTIAL RIDING MOWER
