Calculate My Digital Carbon Footprint

I will calculate my digital carbon footprint and take steps to reduce my CO2 emissions.

COMPLETED
ONE-TIME ACTION

Water

Understand My Water Footprint

Each of us has a water footprint, directly linked to our daily activities as well as the water required in the production of things we use each day. Understanding our water use is important for a healthy planet. I will calculate my water footprint and look for a few ways I can reduce consumption or waste, then share what I learned on the feed.

REFLECTION QUESTION
Energy

Where in your life do you emit the most carbon? What change are you willing to make in your daily life to reduce this output?
Ethan Tammar 10/07/2025 7:40 PM
My overall carbon footprint is quite minimal (3.6T CO2-eq / yr), and the majority of my footprint can't be controlled (even living in an economy triple dorm and eating vegan has some unescapable carbon footprint). There are however actions I could take to marginally lower my footprint. These actions include buying seasonal, local, and unpackaged produce and finding a way to compost unavoidable food waste (like banana peels).

Water

What surprised you most about your water footprint, and how did it influence your perspective on water use? What changes can you make to reduce your water consumption, and how will these impact your daily routine?
Ethan Tammar 10/06/2025 7:34 PM
The thing that surprised me the most was the amount of water I save by being a vegan and by keeping shopping to a minimum. This calculator influenced my perspective on water consumption by showing me that there’s a strong link between having a minimalist lifestyle and limiting water use. The main change I noticed for minimizing my water consumption was the obvious - taking shorter showers.

What did you learn about your digital habits that surprised you the most?
Ethan Tammar 10/05/2025 4:06 PM
I learned that my digital habits overall have a very minimal carbon footprint of around 7.9kg CO2e per year (I can offset that with just 20mi of city biking). This is surprisingly low considering the internet has comparable emissions globally to aviation. I don’t use social media, but surprisingly, 4 hours of browsing a day would multiply my digital emissions by a factor of 10.

What single-use items (e.g. straws, coffee cups, vegetable bags, plastic bags) do you regularly use? What could be substituted instead?
Ethan Tammar 10/05/2025 3:52 PM
I often buy produce and bread contained in plastic containers. I could buy fresh bread in paper containers and buy fruit without a container.

  I try not to use produce bags, too, but I've learned to re-use the bags for those items that need them.

Energy

How is electricity generated where you live? How does it impact the environment, animals, and humans?
Ethan Tammar 10/05/2025 3:48 PM
At OSU, there are many initiatives to improve solar electricity generation, however a lot of our energy still comes from natural gas. Natural gas has minimal local effects since it doesn’t emit particulate matter, however it has a severe effect on the climate. Due to natural gas deposit leaks, natural gas can have similar climate effects to coal.
