Carbon Footprint Basics for Personal Transportation
What Is a Carbon Footprint?
A carbon footprint represents the total greenhouse gas emissions - measured in carbon dioxide equivalents (CO₂e) - generated by your daily activities. This measurement accounts for various greenhouse gases, like methane and nitrous oxide, by comparing their global warming potential to that of CO₂.
"Greenhouse gas emissions are often measured in carbon dioxide (CO2) equivalent. To convert emissions of a gas into CO2 equivalent, its emissions are multiplied by the gas's Global Warming Potential (GWP)."
When it comes to personal transportation, your carbon footprint includes emissions from fuel use, electricity consumption, and even the manufacturing of your vehicle. Electric roller skates, like Wheelfeet, have a smaller footprint since they produce no direct emissions during use. Their environmental impact comes mainly from the electricity used for charging and the resources involved in their production.
In 2022, transportation accounted for 29% of all greenhouse gas emissions in the U.S.. By understanding your personal impact, you can make smarter choices - like opting for eco-friendly commuting options such as electric roller skates.
Next, let’s dive into the key factors that shape the carbon footprint of e-skates.
Factors That Affect E-Skate Carbon Footprint
Several factors influence the overall carbon footprint of electric roller skates:
- Electricity Consumption: Charging your e-skates is the biggest contributor. The emissions depend on how your local power grid generates electricity. Regions relying more on renewable energy sources, like wind or solar, have lower emissions per charge.
- Battery Production: Lithium-ion batteries require a lot of energy to produce, particularly during mining and manufacturing. While this creates a significant upfront carbon cost, the impact diminishes over time as the battery powers thousands of rides.
- Material Sourcing and Manufacturing: Producing e-skates involves extracting and processing materials like aluminum, plastic, and electronic components. However, their compact size means they use fewer resources compared to larger vehicles.
- Product Lifespan: A durable product reduces the per-ride carbon impact by spreading manufacturing emissions across more uses. Wheelfeet e-skates are built to last, with replaceable parts and proper maintenance further extending their lifespan.

Measurement Units for U.S. Users
To better understand and calculate the carbon footprint of e-skates, here are the key units commonly used in the U.S.:
- Pounds of CO₂ Equivalent: This is the standard unit for expressing carbon footprints in the U.S., offering a relatable way to grasp emissions.
"In certain regions, pounds are used as a unit of measurement for carbon footprints. This unit is particularly familiar to audiences in the United States, where the imperial system is still commonly used."
- Kilowatt-Hours (kWh): This measures the electricity consumed during charging. A typical Wheelfeet charge uses about 0.1 to 0.2 kWh, depending on the battery capacity and charging efficiency. This unit helps link energy use to local emission rates.
- Miles per Charge and Passenger-Miles: These metrics help you evaluate emissions over a distance. For example, you can estimate emissions as "pounds of CO₂ per mile traveled", allowing for comparisons with other commuting methods.
- Carbon Intensity: Expressed as "pounds of CO₂ per kWh", this value shows how much CO₂ is emitted for each kilowatt-hour of electricity consumed. The U.S. national average is approximately 0.85 pounds of CO₂ per kWh, though states with more renewable energy sources report lower figures.
How to Calculate E-Skate Carbon Footprint
Data You Need for Calculations
To calculate the carbon footprint of your electric skates, you'll need three main data points: energy consumption per charge, range per charge, and local grid carbon intensity.
First, check the energy consumption (in kWh) for your skates. For Wheelfeet electric roller skates, this information is typically found on the manufacturer's website or in the product documentation.
Next, determine the range per charge. Wheelfeet skates, for example, can travel up to 9 miles on a single charge. Keep in mind that factors like rider weight, terrain, and riding habits can impact this range.
Finally, identify your local grid's carbon intensity, which measures CO₂ emissions per kilowatt-hour of electricity. In 2023, the U.S. average was about 0.81 pounds of CO₂ per kWh. You can find specific regional data using tools like the EPA's eGRID Power Profiler or the U.S. Energy Information Administration (EIA) state-level emissions data. The EIA provides this data in pounds per megawatt-hour (MWh), which you can easily convert to pounds per kWh by dividing by 1,000.
Basic Calculation Method
Once you’ve gathered the necessary data, use this formula to calculate your carbon footprint:
Carbon Footprint per Mile = (Electricity per Charge × Carbon Intensity) ÷ Miles per Charge
Here’s how it works:
- Multiply the energy consumption per charge (in kWh) by your local grid's carbon intensity (in pounds of CO₂ per kWh). This gives you the total emissions for one full charge.
- Divide that total by the range per charge (miles) to calculate emissions per mile.
For instance, if your skates consume 0.15 kWh per charge, and your local grid emits 0.81 pounds of CO₂ per kWh, the calculation would look like this:
- 0.15 kWh × 0.81 pounds CO₂/kWh = 0.12 pounds of CO₂ per charge
- 0.12 pounds CO₂ ÷ 9 miles = 0.013 pounds of CO₂ per mile
The EPA’s eGRID database is an excellent resource for accessing up-to-date emissions data. It includes detailed environmental characteristics of nearly all electricity generated in the U.S., ensuring your calculations are as precise as possible.
Sample Calculation Using Wheelfeet E-Skates
Let’s break it down with Wheelfeet skates using the 2023 U.S. national average for electricity emissions:
Step 1: Calculate emissions per charge
0.15 kWh × 0.81 pounds CO₂/kWh = 0.12 pounds of CO₂ per charge
Step 2: Calculate emissions per mile
0.12 pounds CO₂ ÷ 9 miles = 0.013 pounds of CO₂ per mile
This means traveling one mile produces about 0.013 pounds of CO₂. For a 5-mile trip, emissions would total 0.065 pounds of CO₂, while a 20-mile journey would emit 0.26 pounds of CO₂.
If your local electricity grid relies more on renewable energy sources, your carbon footprint per mile could be even lower.
