How to Reduce Your Carbon Footprint

Carbon Footprint Reduction Tips

We help you understand and learn how to reduce your carbon footprint through daily activities and lifestyle changes.


A carbon footprint is the sum total of greenhouse gases produced by an individual or group, expressed as carbon dioxide emission equivalents (‘CO2e’).

  • Humankind’s global carbon footprint is the total number of greenhouse gases produced to directly and indirectly support human activities.
  • An individual’s personal carbon footprint is the total number of greenhouse gases produced to directly and indirectly support that person’s activities over a given timeframe.

Examples of individual activities that directly produce CO2e:

  • Heating, cooling, or powering one’s home;
  • Driving or riding in a vehicle; and
  • Disposing of compostable food waste in a landfill.

Examples of individual activities that indirectly produce CO2e:

  • Eating meat or animal products;
  • Buying consumer goods; and
  • Not recycling plastics and other recyclables.

The Ecological Footprint measures how fast we consume resources and generate waste. It measures the ecological assets that a population (For example, the United States) requires to produce the natural resources it consumes, and to absorb its waste (especially CO2e).

RePrint focuses on tracking and reducing the carbon footprint of individuals. Learn more about humankind’s global carbon footprint and our Ecological Footprint here.


Carbon dioxide, or CO2, is an odorless, colorless, poisonous gas that is created by carbon combustion (when powering automobiles or generating electricity), and the respiration processes of living organisms. ‘Carbon emissions’ refers to the release of this greenhouse gas into the atmosphere. Although the terms ‘greenhouse gases’ and ‘carbon emissions’ are often used interchangeably, CO2 is not the only greenhouse gas (Methane is another particularly harmful one).


There are many ways to reduce your personal carbon footprint. According to a recent study, the most effective ways to reduce your impact are as follows:

  1. Have fewer children;
  2. If you have a gas or diesel-powered vehicle, live vehicle free;
  3. Avoid flying as much as possible since flying emissions are 2x as harmful as those from driving;
  4. Buy green energy;
  5. Replace a gas or diesel-powered vehicle with an electric vehicle;
  6. If you have an electric vehicle, live vehicle-free;
  7. Eat a plant-based diet (i.e. Eat less meat and animal-derived products);
  8. Replace a gas or diesel-powered vehicle with a hybrid;
  9. Wash clothes in cold water;
  10. Recycle;
  11. Hang-dry clothes;
  12. Upgrade lightbulbs to LEDs.
