When most people think of pollution, they picture highways jammed with cars or smokestacks on the horizon.
But one of the worst offenders could be sitting quietly in your garage.

Four-stroke gas engines—the kind found in lawn mowers, snow blowers, generators, and other common equipment—may be small, but their emissions pack a punch.

What’s Really Coming Out of That Muffler

Carbon Monoxide (CO)
An invisible, odorless gas that disrupts your body’s ability to carry oxygen. Even short-term exposure can cause headaches, dizziness, or nausea. In high concentrations, it can be deadly.

Nitrogen Oxides (NOx)
These gases react with sunlight to create ground-level ozone and smog. They aggravate asthma, reduce lung function, and can cause lasting respiratory damage.

Volatile Organic Compounds (VOCs)
When mixed with NOx, VOCs form ozone—another harmful air pollutant that attacks your lungs and worsens air quality for entire communities.

The Shocking Scale of the Problem

According to the California Air Resources Board, running a gas-powered lawn mower for just one hour can produce as much smog-forming pollution as driving a brand-new car for 300 miles.

That’s one afternoon of yard work equaling a road trip from Los Angeles to Las Vegas.

How It Affects You Directly

Immediate Health Risks
Users breathe these emissions up close, risking headaches, nausea, eye irritation, and breathing problems—often within minutes.

Long-Term Health Damage
Over time, exposure increases the risk of chronic respiratory illness, heart disease, and other serious health issues.

Noise Pollution
Even with a muffler, a four-stroke engine is loud enough to cause hearing loss over years of use and adds unnecessary stress to your environment.

Why Switch to Electric?

Converting your existing equipment to electric eliminates tailpipe emissions entirely.
No carbon monoxide. No smog-forming gases. No toxic exhaust cloud around you.

The result is:

• Cleaner air for you and your neighbors

• Quieter operation that protects your hearing

• Healthier communities and a smaller environmental footprint
