Students from around the world calculated their class mean and standard deviations for their footprints and posted them on our world map.
Do you see differences across the globe? If so, why do you think those differences exist?
Did you use the calculator to try to reduce your footprint down to the average from a citizen of another country? What changes would you have to make to lower your footprint in this way? Are you going to try and take some of these actions in your daily life?
Student Footprints

I was very surprised to see how high my carbon footprint was, especially from the amount of traveling I did. I think, in my general area the carbon footprint was so high because most of the people in my neighborhood leave their lights on in their house before they leave for the day, which usually means they'll be gone for several hours of the day. I also do this sometimes but I should stop to reduce my carbon footprint, I think other people can also stop doing things like leaving the water running and using their cars to travel places that are close to reduce fossil fuel emissions.

Many of us are probably used to eating meat, dairy, eggs and other animal products quite frequently, if not every day. What a lot of us don't know (or choose to ignore) is the horrors that go on inside the meat/animal product industry. The animals in them are subjected to short, tortuous lives, with many living cramped together and in inhumane conditions. In addition to all of that, it is horrible to the environment, with factory farming being one of the leading cause of greenhouse gases worldwide.Eating less meat could help to reduce our carbon emissions as a group effort, and would help the environment and the animals as well.

As a student who has lots of activities to do in and outside of school, I can’t always use public transportation. This is one of my personal reasons for my high carbon footprint, as I’m sure it is for many other students. A way for our cities to combat this is by making it more accessible. Instead of me having to walk a mile to the correct bus stop and then walking two more to get to where I need to be, it is majorly inconvenient. Also, when I have used public transportation to get to where I need to go, I am often late. If cities can implement a way to make more specific public transport, that would help this issue. I understand that this wouldn't be easy and is risky if people don’t end up using it, but with a good amount of promotion, it can work.

The fact that the carbon footprint survey asked us where we live got me thinking. Where should our actions and next steps be focused? Nobody can really help where they live, and I doubt that anyone is going to uproot their lives just to reduce their carbon footprint. And while humans leave a very large carbon footprint, I think reduction efforts should be focused in places that can implement those changes. It wouldn't make sense for us to focus our efforts in a rural countryside where everyone already lives frugally, but it also wouldn't make sense to pour all of the effort into a place like New York City that is already super industrialized. If we did that, we would be putting in a lot of effort without a lot of reward. Instead, if we focus on more suburban neighborhoods and towns, that amount of effort could really change things. I learned through my survey that most of my carbon footprint comes from transportation. I can't exactly help transportation because I can't drive and live in a big city, but for people who CAN help it, they should, not by completely cutting all individual transportation, but by giving a friend a ride to work, or taking the subway on Fridays. Stop focusing on the big picture. If you do that, you'll get tunnel vision. Focus on the little ways you can help and do everything you can. Not doing so is the same philosophy as saying "Oh, darn, I only have 45 minutes to work out today instead of an hour. I guess I'm better off just not working out at all." It's always better to do something, even if it's half-assed, because half-assing something is still doing it. So, focus on the little ways to reduce carbon footprint, and know that every little thing done has the potential to make a big difference.

After I completed the I2Sea carbon footprint calculator, I became more aware of the things I mindlessly do daily that really impact it. For the most part my carbon footprint was lower than the average in my area, but my transportation levels were a prominent outlier. I didn't expect them to be that high, but it makes sense since I recently took a big trip to Japan and Korea over my spring break that included a 11 hour plane ride one way. If it not were for that trip, I think the levels would have been lower. My home, food and purchase levels were drastically lower than the average. However, my purchases were ten times lower than the average calculations. So I think this calculator is pretty accurate since it separates the carbon footprint levels into sections or certain parts in our lives, but at the same time one thing like my trip can kinda throw it all off.

I believe that traveling is a great way to make connections and experience cultures all over the world. However, traveling is often bad for the environment, especially when done a lot. I propose that people should try to make the switch to electric vehicles instead of gasoline vehicles and they should try to be mindful of the environment when traveling.

Individuals should not be able to own private planes because carbon emissions from that are the highest and I don't want to discourage people from traveling because it is a good thing for culture but people could watch what they do in other countries and how they treat the environment

To me these two words are often merged into one word which is not right. Sometimes wants are even mistaken as needs. As a conservative person, it confuses me when people seem to buy things they want when it is really a waste of money. This belief that wants are a need are even fueling causes of climate change like fast fashion where people want to and buy the cheaply made products. If these clothes were really a need then we would go to places like thrift stores more often because they would sell the clothes we needed for much cheaper.

Rampant consumerism is a very large issue in the world today. Many people feel like they always need the newest and trendiest thing, but having those things does more harm than good. What we often don’t realize is that buying new products like clothes, makeup, and other commodities hurts our environment. Due to things like international shipping, the materials used to create the products, and how they were created, harmful gas emissions are driven up. Also, oftentimes these products are thrown away when the person feels like they don’t need them anymore, and because people don’t always dispose of their waste properly, thousands of tons of discarded products end up in landfills, creating a cycle of environmental harm that cannot be undone, unless people make large-scale changes to their consumer habits. These changes could be thrifting clothes more instead of shopping fast fashion, or choosing to shop from more eco-friendly brands.

Instead of transportation we need to create communites that are more encourging to walking and biking. Though electric cars can solve part of the problem the main problem is how our communites are built to revolve around cars. My highest contributer to my carbon footprint was the transportation section this is since everyone relys on cars so much since not all communies have stores close to their communtiy so they need cars to drive to get basic nesesistys. A community centerd towards walking and biking would have all the nesary stores and food very close to or within the town. This would encourage peopel to walk since it would not be an imense amount of effort. As well as helping our planet biking and walking helps people loose weight inturn leading to a more healthy society.

Many people don’t realize that throwing away food also means wasting all the energy it took to grow, ship, and store it. When food ends up in landfills, it rots and releases methane—a gas that’s way worse for the environment than carbon dioxide. In the Article" Food Waste and Climate Footprint," I learned that if food waste were a country, it would be the third-largest emitter of greenhouse gases after the U.S. and China. I started focusing on this in my everyday life, while doing this I learned that “best by” dates aren’t always accurate, so I don’t throw stuff out just because the label says so. Cutting food waste isn't a hard problem to fix it just means we have to be more aware.

Did you know 28% of the U.S co2 emmisons come from transportation. Alot of people abuse their ablity to drive somewhere because it's more convient, and can get us from place to place faster, but as we know the earth is dying due to us. We learned in an edpuzzle in class that if we put the earth existents in a 24hour spectrum we've only been on the earth for 4 seconds, and we've already caused thousands of animal to go exist, and ecosystems to be destroyed. The Industrial Revolution, became the power house to rise in greenhouse emmsions. and ever since the average global amount of co2 has increased drastically in the past 40 years. so instead getting car to go to the park, maybe you should run or ride bike, to save the eath step by step.

After finishing the carbon footprint survey, I had noticed that for food, I produced twice the normal amount of carbon. This was likely the case probably due to the fact that my diet was based around meat and lacked a healthy amount of vegetables. However, if you lack a healthy amount of meat, our energy will severely decrease causing us to feel tired and nauseous. Realizing that this is a problem, I wonder what would be a better alternative than just going vegetarian? After some time I had learned that tofu and beans produces less carbon then meat and have about the same amount of protein as meat. If enough people reduce their diet to beans and and tofu, the earths carbon can drastically go down by 25%. Although, are diets do not need to be restricted to only tofu and beans, we can have meat on certain occasions, but we should not have it every day if we want to reduce our carbon footprint.

With fast fashion brands becoming more apparent in the last decade, carbon emissions from clothing have significantly increased. Not only have more clothes been thrown in the landfill, but the higher demand for clothing to fit a specific trend has led to much higher carbon emissions. The increase in social media has promoted trends and fast fashion more than ever. Also, the process of making clothes and shipping them all around the world affects fashion companies' carbon footprints. According to the UN Environment Programme in a 2019 report, "the fashion industry is responsible for about 10% of global carbon emissions." This statistic highlights how the fashion industry is becoming a problem and has a very strong impact on the world's carbon footprint. Fast Fashion has added to the problem of the world's carbon footprint.

While doing my calculations, I noticed that a carnivore diet with four people produces a lot of CO2.

I agree that carnivore diets produces greater amounts of CO2 than a vegetarian or vegan diet. This is due to many things but one of the greatest contributors is the food needed to feed the animals that could have been used to just feed humans. Personally when driving past cow farms it highlights all of the resources needed to create meat.

Throughout this questionnaire, I have answered questions about what my actions do to the environment. I thought that my biggest carbon emission would be due to transport, but it was not. The food emission was the biggest contribution, with the amount of 3,465 kgs. This makes me think about how much I eat, but also what I do with my food afterward. I saw that someone also had the same outcome. My one question is, if I need food as a student athlete, what can I do to lower my food emissions?

Looking deeper into the cause of my carbon footprint revealed how much the location of one’s community can affect their carbon usage. For example, living in the U.S. means long distance travel is extremely common as things are so far apart from one another. Flying for week long trips or even for single day trips happens with regularity all throughout the U.S., immensely increasing the country’s global footprint. Unlike some other nations, we don’t have a long distance travel alternative like a train, so people resort to flying, one of the highest producers of carbon in all technology. On a local level, simple things like being walking distance from your school can have a huge impact on your carbon footprint. Driving for your daily commute adds up, eventually making a big impact on carbon emissions into the atmosphere, so being smart with short distance transportation such as walking or biking, makes a big difference in the long run.

There are profound ways in which students can adopt the following to help to reduce their carbon footprint. One of the ways of converting it is through the transformation of physical resources to digital resources for academic work. For instance: Instead of re-printing out numerous drafts of a potential dissertation students can use online platforms and services. Instructors who require assistance to complete their work can easily look for services and get quality services while remaining environmentally friendly. Students also save trees when they use computers as they replaced the drain of energy and cutting down trees during the writing process.

I greatly agree with this statement. replacing physical resources to digital resources really could make a difference with reducing our carbon footprint by not using certain physical sources, like papers and such. Considering paper is more cheap than digital devices, do you think money could be a roadblock to this carbon footprint solution, considering some countries may not have the money to provide these digital resources? as stated in many sources, some countries do not provide money for education, like Comoros, where education spending is around 2.4% of the total GDP. In addition, At my old school, we could not afford enough computers for every class, resulting to most of our work being done on paper. Your idea displayed can definitely help many schools and students around the world reduce their carbon footprints, but I do think money could be a big factor between whether certain schools and students can or cannot switch to this decision.

I agree, I notice that a majority of paper in classrooms comes from the mandate of notebooks, rather than online documents. I wonder how much of a difference using technology would make? I understand that it can be difficult to implement this in classrooms, because technology comes with distraction. I am curious as to how this might be solved. Technology can have a negative impact itself, and as stated above is quite costly. Is there a way to make technology more accessible, and more carbon and hydrogen efficient?

After using the I2sea carbon emissions calculator, I was pleased to find that my carbon footprint was below the average for most categories in California, except for transportation. This didn’t come as a surprise, but I was a bit confused because I don't ride in the car that often, I take the bus whenever I can, and I only went on one round trip by plane this year. I started to wonder what steps I could take to reduce my carbon emissions from flying. Is there a way to fly without burning fossil fuels and realseing harmful gasses into the environment? Additionally, the I2sea calculator prompted me to think more critically about what our school lunches consist of each day. Overall, the lunch program is pretty good; my school uses compostable plates in the main areas. However, many items are still wrapped in plastic. Even with the main food served on compostable plates, a lot of non-compostable trash is generated during lunch, and many people don’t properly sort their waste before disposing of it. This must be harmful to the environment, as the plastic can release harmful gases into the atmosphere.

I just measured my carbon footprint and was relieved that most of my results were below average in all categories. Something I noticed, however, was that while all of my other categories produced less that 700 kgs annually, my travel footprint was over 2000 kgs. My cars are electric and I hardly use anything else to travel, so I imagine most of this came from air travel--that is, the singular round trip flight I've taken in the past year. I knew air travel produced a lot of CO2, but that was even more than I thought. Are there cleaner ways to fly? Is that currently something that even exists?

After doing the carbon forum, I really realized how much our actions as students can contribute to climate change. Everyday choices like how we get to school, what we eat, or how much we rely on technology can add up to huge impacts. For example, using a car instead of biking or walking increases greenhouse gas emissions, while lots of energy is used for streaming or charging devices, contributing to our overall footprint. According to the i2sea data and resources, these choices affect not only our immediate environment but also global sea level rise. Personally, I’ve started making a few changes, like bringing a reusable water bottle to school. I am also trying to reduce the amount of meat I eat. These efforts might seem small, but they are the first steps in lowering my own environmental impact. As students, we need to be responsible to be more conscious of our daily habits. Tools like i2sea help us see the connection between our footprint and global consequences, motivating us to take more meaningful action.

Hi everyone,
Recently, I have been trying to reduce my carbon footprint because I believe small actions can make a big difference.
I started by using my bike instead of a car whenever possible, recycling more carefully, and saving energy at home.
Also, I try to eat less meat and buy local products to support sustainable farming.
It is not always easy, but I think it's important for our future.
What do you do to reduce your carbon footprint? I'd love to hear your ideas!

Hi Ivan122! I really admire what you are doing to try and reduce your carbon footprint! I try to practice a lot of those things at home too, because not only do they help reduce your carbon footprint but they also help keep you healthy. I agree that we should do whatever we can to help our environment and protect it for the future. Another thing that I really try to do is think about my water consumption and heating use. A long hot shower is really relaxing but it also takes a lot more energy to heat all that water for such a long period of time. In my day-to-day life, I personally find that I don’t mind taking shorter showers so that is something I try to do! I really enjoyed hearing someone else’s ideas on ways to reduce our carbon footprints.

Hi Ivan! I like how you are trying to reduce your carbon footprint by biking more and saving energy in you home. I have also been trying to cut down on eating meat, although my attempts have only partially been successful. After calculating my carbon footprint, I noticed that my transportation is way above the average. Although I do like traveling, I realize I should cut down on it and maybe stick to local trips to do. I live close to many good hiking trails so I'm thinking about exploring there instead. I would also love to bike more. I think your choice about biking instead of driving a car is a really great idea I could also implement where I live. Thank you for sharing your ideas to reduce your carbon footprint!

My Household’s Carbon Footprint – Eye-Opening Transportation Impact
After calculating my household’s carbon footprint on the i2Sea website, I was surprised by how much higher my total emissions were compared to the average in my region. The biggest difference came from transportation. My household emitted 19,210 kg of CO₂ from transportation, while the regional average is only 2,557 kg. This gap is mainly due to frequent flying. My family took 46 flights, which alone added up to over 8,000 kg of CO₂.
In contrast, my household’s home energy use was 5,550 kg (compared to 3,757 kg regionally), and food emissions were slightly below average at 2,061 kg. Interestingly, my purchases were much lower than the regional average (268 kg vs. 1,191 kg), which might be because we try not to buy new clothes or electronics often.
This data really helped me see how certain choices — especially travel — can hugely affect the climate. I think it’s important to consider reducing air travel or using carbon offsets in the future. I learned that even if I try to be careful in some areas, one big category like transportation can outweigh all the rest.
This connects with what we’ve been learning about individual action and carbon footprints. According to climate science research, transportation is one of the leading sources of emissions globally, especially in high-income countries. It’s clear that personal choices — like flying less — can make a real difference.

While doing the calculations to know my total carbon dioxide, I found out that a high percent of emissions was from transportation. Now that I know this, i found alternatives to lower the transportation emissions. Some alternatives are using public transportation, carpooling and getting electric cars in the future. I think carpooling is such a great alternative. Not only do you gain friendship, but you actually reduce the carbon emissions because only one car is driven. What I also found out is that my calorie intake, and food production is extremely high. Is this because of the meat that I eat? What are ways I can reduce this?
