The True Environmental Impact of Electric Scooters

The True Environmental Impact of Electric Scooters

It’s beyond question that we must drastically reduce carbon emissions in the coming years to head off the worst effects of climate change. How we do that has been a matter of considerably drawn-out debate. As individuals, it can be hard to know where to invest our time and money. Our actions can seem to have little impact; the problem can feel even more overwhelming in the midst of the COVID-19 pandemic, when many of the systems we’ve depended on have shown themselves inadequate or unsafe. 

Extreme weather has already driven up energy usage. A New York City greenhouse gas inventory found an 18% increase in usage in the summer of 2018, and a 13% increase during the winter months. These increases have not, however, been offset by a decrease in auto emissions.

The study also found that emissions from passenger cars, the greatest contributor to the city’s air pollution, have only fallen by 1% since 2005.

Indeed, the EPA has found that transportation costs overall, including cars, trucks, ships, trains, and planes, make up over 28% of greenhouse gas emissions in the U.S., the largest contributor to climate change in the country. Over half of these emissions come from passenger cars and trucks. While the auto industry has been investing heavily in the development of electric cars, they are not moving quickly enough to replace internal combustion engines in the next few decades. Cars also have lifecycles spanning decades, and this drastically increases the time it will take for electric cars to make a real impact on emissions, not to mention the weight upon both infrastructure and the supply chain to produce and move 4,000-7,000 pound vehicles, even if they are electric.

While other industries, especially power, have worked to reduce their carbon footprint, emissions in the land transportation sector have worsened in the last several years as the industry’s expansion outpaces its ability to innovate.  


Americans rely on their cars to cross long distances and navigate cities designed around the highway. But half of all car trips are under 3 miles (a well studied fact)—short trips that can be covered by walking, biking, or riding an eco-friendly electric scooter. These car trips cause more infrastructural wear and further produce emissions via idling cars in stop-and-go traffic. Micromobility advocates have argued for years that eco-friendly lightweight electric vehicles can cover most of those trips, at 1-2% of the emissions of cars.  

As we can see in the graph below, lightweight electric vehicles create very low emissions in comparison to other modes of travel. It is highly of note here that the electric scooters being referred are dockless shared scooter fleets (like with Bird and Lime), which are more intensive in environmental impact due to their unique manufacturing, maintenance, and city rebalancing costs. In reality, owned scooters like the Unagi Model One are closer to E-bikes on the chart.


It’s true that the sharing industry has been improving in both these respects, making more durable scooters and transitioning to removable batteries and electric vehicles. But it will continue to be a sizable difference compared to privately-owned electric scooters, which do not come with pieces of carbon baggage attached. Small, fast, lightweight folding scooters are, by far, the most exciting and convenient way to travel short distances, and they are also one of the most eco-friendly options.


In fact, the differences between driving and taking an electric scooter on a trip to the grocery store, coffee shop, or office could not be more dramatic. Just “as a matter of physics,” writes Micromobility Industry’s Oliver Bruce, “it’s a no brainer that scooters are better for the environment than cars,” especially without the added environmental costs of fleet maintenance: 

It takes less energy to transport a 100-kilogram passenger using a 20-kilogram vehicle with a 90% efficient electric powertrain than it does to accomplish the same task using a 2,000-kilogram vehicle with a 30% efficient internal combustion powertrain. When you replace a car trip with a scooter trip, you’re pushing 17 times less weight three times more efficiently.

Privately-owned electric scooters are without a doubt one of the most eco-friendly ways to travel short distances, next to walking or riding a traditional non-motorized bicycle or kick scooter or skateboard. And they’re cheaper too (we made a commute cost calculator to demonstrate that additionally shows CO2 emissions).


The environmental benefits of owning a scooter have become even more apparent during the COVID-19 crisis, during which we have seen a historic drop in carbon emissions due to lockdowns, travel restrictions, and work-from-home orders. Anxiety about taking public transit in major cities has led to majorly increased demand for electric scooters. 

The industry is rebounding from a “nuclear winter,” says Quemuel Arroyo, the global head of community at Charge, a company setting up public charging stations for e-scooters. Scooters are now seeing a “much higher demand than ever before,” and that demand is trending toward more convenient and eco-friendly private scooters, investors believe. The more people in urban areas adopt micromobility solutions like privately-owned electric scooters, the better the news will be for the environment. 

There may be little doubt about the harmful effects of fossil fuel emissions on global temperatures. Governments and private industry need to do much more to lower emissions in the coming years. But there should also be little doubt that owning a fast, reliable, portable, and fun electric scooter like Unagi is one of the best ways individuals can lessen their environmental impact and make positive change for the world.
