My footprint

Hello, I'm Mario, I live in Dénia and I'm going to show you my carbon footprint per year, first at home 4545kg per year, second food 2395kg per year, third, purchases 133kg per year and finally transportation 489kg per year. What do you think I could do to reduce that percentage?

Hi, I’m Nicolas. I suggest trying for your home footprint to unplug electronics before turning yourself in for the night. For food, Having more local or seasonal dishes or buy groceries in bulk with reusable containers that can reduces the packaging waste associated with individually packaged items. For purchases, You can try repairing it instead of getting something new to replace it like a jacket or a bicycle. Finally your transportation,you can try walking for a change for closer places that you need to go and only drive If you think it's really far.

Hello Mario, my name is Mekennah! I see you already got some recommendations, but I wanted to throw in a couple more! for your home footprint, it is very easy to walk out of a room without turning off the light or shower a little extra longer because of stressful days. Trying to reduce those could really help lower your footprint. My footprint for food was a big one for me as well. What I figured might help me is trying my local farmers market and finding fruits and vegetables that are grown without a bunch of pesticides that are harmful to our environment. Lastly, the hardest one yet is transportation. It is so convenient to get in the car or on a plane and vacation or commute to work/school- however, maybe carpooling or minimizing vacation travel might help with that! Bet of luck!

I don't know if this could help you, but many of my friends grow vegetables and raise animals so I have started buying their produce, eggs and meat to reduce my carbon footprint.

Wants or Needs

The strong want to be able to have the popular things/items that are seen all over the internet, muddle the opinion of whether it is actually needed, or do we want it so bad that it feels like we need it? Lots of things are bought because someone wants it, but when something is needed, people noticeably slack on buy that item because it isn't wanted.

Lizzybeth   2025-10-04 17:08:40 in Wants or Needs?

I agree with this, that many of the expensive things we buy are not necessities. However, in the world we live in it is a prised thing to have the coolest new thing or the next celebrity item. Along with people having the need to seem cool or fit in. This goes to show that everything we do contributes to climate change even as something as simple as buying the next popular clothing item to fit in because not only does it lead to over consumption but it leads to our judgment about wants vs needs being clouded.

Naokiwads   Yesterday 21:51:40 in Wants or Needs?

I could see how people want to follow the latest clothing trends, buy celebrity items, and buy the coolest new things to try and fit in but Ive never bought celebrity items, my I phone is over five years old, and Ive had the same set of clothes for the past three years. despite this, Ive never struggled with fitting in or wanting to look cool. I have also rarely bought things out of a want to look cool and really only buy things out of necessity and occasionally for my hobbies.

the result ,I can make better

My carbon footprint is 5,758 kg of CO₂ per year, a little lower than the average for Spain, which is 6,968 kg, although it is still higher than the global average. Looking at the results, what pollutes the most in my case is food and home. I think I could improve a few things to reduce my footprint. For example, at home I could turn off the lights more when I don't need them, use energy-saving light bulbs and not leave appliances plugged in. As for food, you could try to eat less meat, especially beef, and more local or seasonal products. I could also avoid so much plastic and buy only what I really need, because I have little in "shopping", but I could still improve it more. In transport I hardly pollute, so that's fine, but in general I would like to continue to lower my footprint and be more aware of the things I do in my day to day.

Mgreen28-SJRState   Yesterday 13:46:23 in Student Footprints

Hello Amalhadjaj! I also have a higher home footprint. I like how you suggested the energy-saving lightbulbs! I would have never thought of that. I use lights often in my house for many hours of the day and in multiple rooms because I have a kid who runs everywhere! Investing in the lightbulbs may really help my footprint! Another way to reduce your food, if you're open to suggestions, is shopping locally and looking for organic foods. Many grocery stores have great fruits and veggies; however, they often come from a place that uses so many pesticides that they have such a huge impact on our environment! Another note to add is I have just recently recycled all of my plastic Tupperware and changed to glass containers! They are also a lot easier to clean! I hope we both have success at lowering our carbon footprint!

Grocery shopping

I think an interesting way to reduce my home carbon footprint is to only grocery shop for a few days at a time instead of the whole week, thereby increasing the chance that no food is left out throughout the week.

my idea to lessen my transportation footprint

My total transportation footprint is 14,280 kgs, which is 10,833 more than the average for the United States of Florida. I aim to reduce my footprint by driving less on the road or by finding lower-speed routes to take.

Reuse and Repurpose

A good way to reuse and repurpose would be to thrift clothing, eat all leftovers before making more food, and use things you think are useless and give them a purpose to lessen your carbon output, so, like cans or bottles, could be repurposed to hold other things like jewelry, hair ties, and other items to help lessen the waste.

ivanpre-sjrstate   2025-11-04 20:48:29 in Reuse & Repurpose

I'm a big advocate for thrift shopping, especially if one can't afford to buy name-brand clothing articles. Thrift stores are easy to find, and the prices for the clothes are much less compared to clothes in bigger stores (Walmart, Target) or name-brand stores (Hollister, Levi's).

Repurposing items to give them a 'second-life' is also smart. There are myriads of videos on YouTube that can help a person craft useful items with random, household objects that are usually thrown away.

Buying Local

Product shipping and delivery is a significant contributor to climate change. Although freight shipping accounts for 3% of worldwide greenhouse gas emissions, the numbers could rise dramatically in the next couple of decades. Additionally, not only does international shipping and delivery result in the burning of fossil fuels for transporting goods long distances, but it also oftentimes result in a lot of excess packaging and plastic waste. The alternative to this is shopping in-stores or supporting local businesses to reduce the amount of fossil fuels being burned for transportation and the amount of plastic waste from excess packaging. Unless it's imperative to buy something online or internationally, it's overall more environmentally friendly to buy local in order to reduce your carbon footprint from shipping.

ivanpre-sjrstate   2025-11-04 20:22:51 in Wants or Needs?

I agree with your notion of it being more environmentally friendly to buy from local businesses. Big companies and corporations like Amazon make a good portion of their revenue by deliveries alone. It is obvious that it is in the company's best interests to keep up with these deliveries to maintain their revenue, no matter how environmentally non-friendly some of the practices are.

Local businesses are a nice alternative because it is likely that they use simpler or more 'natural' resources to create their products and goods. These businesses also don't usually have big trucks to transport their goods, which contributes to a cleaner footprint. That isn't to say that some local businesses don't use large trucks or transport vehicles, but compared to larger companies, the carbon footprint is much less for local businesses.

Ways corporations can reduce their carbon footprint.

There is no question that corporations contribute heavily to carbon emissions, especially from their unsustainable business practices. However, if these corporations became more considerate about the harm they cause to the environment, and take steps to reduce the harm, then these can be seen as steps in the right direction.

One way corporations can reduce their carbon footprint is to advocate for eco-friendly utilities, preferably ones that use renewable energy sources. A simple utility for this are solar panels. These panels result in clean, renewable electricity from solar energy.

Another way corporations can reduce their carbon footprint is participating in carbon offsetting programs. Carbon offsetting is the practice of compensating the creation of carbon emissions by taking part in programs that 'cancels out' or at least make equivalent reductions of carbon dioxide. This way, a sort of 'equivalent exchange' can be done in corporations that are mostly run by heavy carbon emissions.

One more method of reducing carbon footprint for corporations is the maintaining of supply chains, and making them energy efficient. This way, waste of resources can be diminished, and clear communication between stations of supply can be sustained.

Ways to reduce one's carbon footprint

Although it may be difficult to maintain a sustainable lifestyle, especially if the culture or society is very materialist, there are creative ways to reduce one's carbon footprint in small ways that can build up over time.

One could be more accepting of 'hand-me-downs' instead of heading to stores and purchasing new clothing; not everything has to be new to be wearable. If one has to buy something, it is better to purchase an item of clothing that is durable, and is able to last a long time.

Another way of reducing carbon footprint is to have a power strip so that every time electronics are not in use, simply switching off the power strip would immediately cease power to the electronics. This is much more efficient than manually pulling the plug of multiple electronics off of multiple wall outlets.

A last example of creative methods to reduce one's carbon footprint is the eco-friendly option of utilizing solar-powered cookers to cook one's food. No need to use the microwave or create long-burning fires to heat up a meal.

The first two ideas, plus more creative methods, can be found in this article: https://sustainability.wisc.edu/14-ways … footprint/

My carbon footprint

Hi, my name is Ainara aand I'm from Dénia, Spain.

My home carbon footprint is way above average. What can I do to lower it?? I think it's because I'm always with the lights on during the day and I keep the fan on during summer all day and night long. I also keep my phone charging all night and sometimes I forget to unplug it. Talking about digital devices, I believe the main problem is that I keep my PC on during at least 12 ours even if I'm not using it out of laziness to turn it back on. Maybe I can also take less time showers to save water too.
I think that's basically the reason my home carbon footprint is that high and that I need to take more care about my actions with my digital devices

My footprint

I have reviewed my results from the carbon footprint assessment and found some areas that I should reflect on and improve. My total footprint is 5,312kg of CO2 per year, which is lower than the average in Spain (6,968 kg), but still higher than the world average (3,791 kg). My biggest expense comes from the household, with 2,635 kg, exceeding the regional average of 1,462 kg. This indicates that I should focus on reducing my energy consumption at home. On the other hand, my food footprint is 2,347 kg, lower than the regional average of 2,620 kg, but I can still improve with a more sustainable diet. In shopping, my footprint is quite low (328 kg) which is good, and in transport it is minimal with 2kg, which reflects my mobility habits.
