Micromobility’s Hidden Carbon Savings, Explained in 5 Simple Charts

Micromobility, like electric scooters, bikes, and roller skates, is quietly cutting urban carbon emissions by replacing short car trips. Over half of U.S. car trips are under three miles, making these devices ideal for reducing pollution. Electric roller skates, for example, produce almost no direct emissions, require less energy to manufacture, and feature regenerative braking to save energy. Cities adopting micromobility can significantly shrink their carbon footprint, with shared services already offsetting millions of pounds of CO₂ annually. These small changes in commuting habits can lead to cleaner air and more efficient urban travel.

Chart 1: Micromobility's Impact on Urban Carbon Emissions

U.S. Urban Transportation Emissions by Mode

Transportation is a major contributor to greenhouse gas emissions in American cities, responsible for one-third of all urban emissions. Unlike traditional vehicles, electric roller skates like Wheelfeet produce almost no direct emissions when in use. They rely on rechargeable batteries, which can be powered by an increasingly cleaner electricity grid.

Here's a striking statistic: over half of all car trips in the U.S. cover less than three miles. With a 9-mile range, electric roller skates are perfectly suited for these short distances. Research suggests that micromobility could replace up to 18% of these short car trips (0–3 miles) in cities like Seattle. This highlights the potential for micromobility to make a real dent in urban emissions.

Colin Murphy, Director of Research and Consulting at the Shared-Use Mobility Center, sums it up well:

"To the degree that it is replacing trips that would otherwise be taken with a car, micromobility has a big climate impact".

Carbon Reduction from Short Trip Replacement

Replacing short car trips with micromobility can yield measurable carbon savings. Take Oswego, New York, for example. Bird Rides estimated that introducing e-scooters there could cut 112,500 pounds - 56 tons - of carbon dioxide emissions annually by replacing car trips. Similarly, in South Lake Tahoe, Lime e-scooters logged over 200,000 rides in 2020, which translated to 186,000 fewer vehicle miles traveled.

Electric roller skates add another layer of efficiency to these efforts. With speeds of up to 15 mph and a range of 9 miles, they’re ideal for short urban trips. Plus, their regenerative braking system captures energy during stops, improving overall efficiency.

The impact of shared micromobility is already evident. In 2022, shared micromobility services helped offset around 74 million pounds of carbon dioxide emissions by replacing car trips across North America.

This data underscores a key point: micromobility isn’t just about convenience - it’s a powerful way to shrink urban carbon footprints by targeting the most frequent car trips. These findings pave the way for deeper exploration in the upcoming charts.

Chart 2: Full Life-Cycle Carbon Footprint of Electric Roller Skates

Life-Cycle Emissions: Electric Roller Skates vs. Gas Vehicles

When you evaluate the entire lifecycle - covering everything from production (including the impact of batteries) to disposal - electric roller skates come out ahead, thanks to their compact size and lightweight design. These features mean they produce significantly fewer emissions during operation compared to traditional vehicles.

To put it in perspective, manufacturing a standard gas-powered sedan generates around 6 metric tons of CO₂, while a full-sized electric car exceeds 10 metric tons. Electric roller skates, with much smaller batteries and simpler builds, require far fewer resources and emit considerably less during production.

The operational advantages are just as striking. Gas-powered vehicles emit roughly 400 grams of CO₂ per mile from tailpipe emissions alone. In contrast, electric roller skates generate zero direct emissions since they run entirely on electricity. Over their entire lifecycle, the minimal emissions from operating electric roller skates more than compensate for their relatively small manufacturing footprint.

These lifecycle benefits become even more compelling when you consider U.S.-specific factors that amplify the environmental advantages of electric roller skates.

U.S.-Specific Life-Cycle Factors

In the United States, commuting habits and energy sources add another layer of eco-friendliness to electric roller skates. Urban commutes are often short, making their typical 9-mile range ideal for daily trips. Additionally, the carbon footprint of charging depends heavily on the energy mix in different regions. Areas with greater reliance on renewable energy sources make electric transportation even cleaner.

While full-sized electric cars may consume up to 50% more water than gas-powered vehicles during battery production, the smaller batteries used in electric roller skates require far less water and fewer raw materials. Charging these skates is also straightforward - they can plug into standard household outlets, often during off-peak hours when cleaner energy is more readily available. Features like regenerative braking, which recaptures energy during stops, further extend their efficiency and spread out manufacturing emissions over years of use.

These factors make electric roller skates a practical and environmentally friendly option for short-distance travel.

This section dives into the numbers, comparing carbon emissions per trip between cars and electric roller skates.

CO₂ Emissions Per Mile by Transportation Mode

When it comes to CO₂ emissions, gas-powered vehicles are heavy hitters. They release far more CO₂ per mile compared to electric alternatives. On the other hand, electric roller skates operate entirely on battery power, meaning they produce zero direct emissions. Even when factoring in the emissions from charging, their overall carbon footprint remains incredibly low. Since most urban trips are short, swapping a car for electric roller skates can lead to a noticeable drop in emissions.

Daily Commute Examples and Carbon Savings

Picture a commuter making a short daily round trip between home and work. Using a car for this journey generates a considerable amount of CO₂. Now, imagine replacing that car with Wheelfeet electric roller skates. With a 9-mile range, regenerative braking, and speeds of up to 15 mph, these skates eliminate those emissions entirely. Over a typical work year, the reduction in CO₂ emissions adds up quickly.

Beyond the environmental perks, electric roller skates can also cut travel time in crowded urban settings, offering a quicker, door-to-door option. These scenarios show how integrating electric roller skates into daily routines can significantly shrink both individual and citywide carbon footprints.

Chart 4: How Regenerative Braking and Design Reduce Emissions

The innovation behind electric roller skates isn’t just about swapping out gas-powered trips. Two standout features - regenerative braking and a lightweight build - work hand in hand to cut energy use and lower carbon emissions.

Carbon Reduction Through Regenerative Braking

Regenerative braking turns kinetic energy into electrical energy during deceleration. In Wheelfeet electric roller skates, the motors shift gears when the rider slows down, acting as generators to capture energy that would otherwise vanish as heat. This reclaimed energy is then stored in the battery, reducing the need for frequent charging and shrinking the carbon footprint of each ride. This feature proves especially useful in cities, where stop-and-go movement is the norm. Combined with this energy recovery, the skates' lightweight design further trims energy demands.

Lightweight Design's Role in Lower Emissions

Weighing just 4.8 lbs (2.2 kg) - a whopping 70% lighter than electric scooters - Wheelfeet electric roller skates need far less energy for acceleration and steady movement. The reduced weight translates to lower energy consumption at every stage of use.

"Because it takes less energy to accelerate a lighter object than a heavier one, lightweight materials offer great potential for increasing vehicle efficiency." - U.S. Department of Energy

Supporting this, the National Academy of Sciences has shown that trimming an object’s weight by 10% can boost fuel efficiency by 5.1%. This lighter design not only stretches battery life but also slashes energy use, making the skates more efficient overall.

"Lightweight designs are recognized as a key solution to improve fuel efficiency and cut emissions." - Journal of Cleaner Production

Together, regenerative braking and a lightweight structure create a powerful combination, delivering meaningful energy savings while reducing carbon emissions.
