Angelina A-US, Oct. 9, 2013

Most of my carbon emission was generated by transportation, but I could not think of a practical way to reduce how much I travel as I live so far from my school. Instead, I decided I would reduce carbon in my home by switching some of my incandescent light bulbs to the more Eco friendly CFL light bulbs. Even still, the cost of regular light bulbs is much cheaper than that of the CFL light bulbs and I cannot therefore replace all of the bulbs. This is a problem that I believe can be solved by people being aware of this problem and mass producing the more expensive bulbs to cut down on costs.

    Hello Angelina! Another option instead of CFL or incandescent light bulbs are light emitting diodes, otherwise known as LED lights. LED lights emit half the amount of carbon emissions that CFL lights produce, and they don't contain the harmful chemical mercury. The lifespan of the average LED light is 50,000 hours, which is much more long-lasting than the 8,000 hour CFL lights and the 1,200 hour incandescent lights. LED lights also use only six to eight watts of electricity, half of the 13-15 watts of energy used to power CFL lights and a fraction of the 60 watts of electricity used to power incandescent lights. For the equivalent of 30 incandescent light bulbs, the annual cost of operation for light emitting diodes is $32.85 per year. All of these factors make LED lights worth looking into. If you want more information on all three bulbs, there are great comparison charts located here: http://www.designrecycleinc.com/led%20comp%20chart.html

Lauren L-USA, Oct. 9, 2013

Hi, my name is Lauren. After calculating my Carbon footprint, I realized that my lowest source of emissions was the purchases category. It was 1363 lbs of CO2 compared to the national average of 6563 lbs of CO2. This is probably due to the fact that I receive hand-me-downs from my cousins about twice a year. Receiving hand me downs is a great money saver, and it saves you from having to make trips to the mall. This in turn reduces your carbon footprint in the transportation category.

    Hi Lauren!
    I agree that hand me downs are a great way to reduce the amount of purchases made by a person. I am the oldest of not only my sisters, but all of my close cousins as well, so I don't receive hand me downs that often. I also can only give hand me downs to one of my sisters, who is 2 years younger than me. Everyone else is far too young and small to be able to wear my clothing, unless they want to keep them for another 10 years (which they don't). Therefore, another good way of reducing purchases made of new clothes is to donate clothes to the Goodwill or other foundations or groups looking for donations - it feels really good to know that you are helping someone in need of clothing!

Hi! My name is Elena. Reducing waste is a great way to cut back on your carbon footprint. This is why I would suggest that we use reusable bags for shopping and groceries. If we could eliminate plastic bags from shopping in Texas, it would greatly diminish the carbon footprint of the state. Eliminating production of plastic bags in one state would then lead to the chain reaction of the stop of plastic bags in other states.

    I agree, using reusable bags for things such as shopping would help reduce our carbon foot print. I suggest that when you go to the mall try and use one bad and put all of your new stuff in that as opposed to carrying lots of bulky bags. Also some stores have options to get your receipt emailed to you instead of getting it printed.

Xandra M-USA, Oct. 9, 2013

Hello! My name is Xandra and I’m from the United States. My carbon footprint was 39452 pounds of CO₂ per year, which is lower than an average of 53573 pounds for Texas, USA but higher than the average of 8358 pounds worldwide.

My lowest carbon emission was purchases, which surprised me because I love to shop. Though, looking back, I realized I did more than I thought I did. I recycle as much as possible, turn down excess packaging supplies for my purchases, and hardly ever get new electronics. My second lowest was transportation, which was something I expected. We skipped out yearly summer trip to the Philippines this year, and I live very close to my school, most of my friends, and other locations I like to go to on the weekends like the mall or the movie theater.

What really shocked me were the activities that produced the highest carbon emissions: home and food. My home carbon emissions were the only average that was higher than the regional average. After reviewing the data, it made sense. Eight out of twelve months we use the air conditioner and four months we use the heater. A lot of the carbon produced was because of careless habits such as forgetting to turn off unnecessary lights or water. I use my laptop for hours at school and then I come home to use it even more for homework. I rarely turn it off unless I’m sleeping, and on Fridays I don’t even do that because I leave it on to do a scan for viruses.

Food was also unexpected, but understandable when you take into account that I eat meat most days. A lot of fossil fuels are used to raise animals who are slaughtered for their meat. There’s an article on http://www.earthsave.org/environment/foodchoices.htm that discusses this. One cow will require approximately 284 gallons of gas in its lifetime to keep up with its eating habits and general maintenance. That’s simply one cow, not to mention the multitude of animals of various species that are killed for food every day. The US also imports a significant amount of meat as well.

To better my carbon footprint, I think the best thing that I can do is just cut back on the small things like turning off electronics, lights, and water, as well as taking shorter showers. When it’s cold, I could opt for a blanket instead of a heater. When it’s hot, I can start up a fan instead of the AC. Maybe once a week or so, my family and I can eat a vegetarian dinner. We could also try to eat more locally grown foods, as they don’t need to be transported as far as other sources. If anyone has any other suggestions, post them below!

My carbon footprint was 22,404. My environmental science class had footprints ranging from 4,786kg-198,982kg carbon released. I noticed that the most differences in carbon released were in food. A lot of people in my class eat vegetarian/organically while others eat non vegetarian. In my own carbon footprint about 11,000kg of carbon is released because I don’t eat vegetarian. The rest of the carbon I released was due to my house. To lower my carbon footprint I’m going to eat more organically and use less electricity in my house.

    good idea to eat less food but you should eat some vegetables too.

    Hi Jessica, I am from the US and my total carbon footprint is 22913 kg of carbon per year. I too need to cut down on the electricity used in my home. How do you plan on doing that? You may want to check what kind of light bulbs you have incandescent bulbs, you may want to think about switching to CFL bulbs. According to http://eartheasy.com/live_energyeff_lighting.htm “CFLs are four times more efficient and last up to 10 times longer than incandescentss.” Because they last longer they are also saving you money. Even though they take a few seconds to heat up, they are worth it. “Replacing a single incandescent bulb with a CFL will keep a half-ton of CO2 out of the atmosphere over the life of the bulb.” Think about replacing every single bulb in your house and how much CO2 you could be saving.

    Another way to put out less carbon through food would be to eat more locally grown and raised food. Most of the food I eat puts out carbon, because I do not eat vegetarian food.

My carbon footprint was higher than the average for my region, but lower than the average for my class. My carbon footprint was 18,462. For transportation mine was 1,296, which was low for my region. For my home it was 12,572,which was higher than the average for my region. For food it was 3,851 which was about average for my region, and for purchases I was under the average for my region with 743.

My carbon footprint was higher than I expected. My results were higher in everything except purchases. In this category I had 559 kg and the average for my region was 1191 kg. My results for transportation were much higher than average. I got 17211 kg and the average was 2557 kg. My results for home and food were a little higher than average, but not by that much.

For my Environmental Science class we all had to calculate our carbon footprint in order to see how much of an impact we were personally having on the environment. I expected my footprint to be close to the average person in my state and country, however, my results were actually worse than the average. The majority of my carbon footprint came from traveling. With 4 plane flights in the past year, and with driving so frequently, my total was close to 9000 just for that section. My purchases was the lowest total, which was the overall consensus from the rest of my class as well. My house wasn’t too bad because I’m not home very often so I don’t use very much electricity. Also, in my household we try to leave the air conditioning off as much a possible, along with the heat. We use fans mostly, and luckily it doesn’t get cold enough in my region that we would need to use the heat often. My food consumption was lower than average, I don’t eat very much meat or have a large intake of calories daily. Overall, my total footprint came to 16,775. Which was about the average in my class, but slightly larger than the average in my region.

    yeah I guess I can relate to that, where just my transportation footprint was the same as the average person in Hong Kong. I know I could change my footprint by not taking flights everywhere though I have to so I can be with my family over the holidays.

Angela L-USA, Oct. 9, 2013

Hi. My name is Angela. For my biology class, we had to calculate our carbon footprint. I partially expected my carbon footprint to be extremely high because the USA has more resources than other countries around the world. I realized through this project that three of the four categories were lower than the average for my region. But, I also noticed that I put out a lot of carbon from my home in daily activities like showering and using lights.
I walked around my house looking for ways that I could decrease my carbon output. I realized that a large majority of my lights were incandescent. I have always heard that CFLs were better, but I didn’t know exactly how so I looked it up. I read that CFLs last significantly longer. Incandescent bulbs last about 2,000 hours while CFLs can last up to 35,000 hours. The price for CFLs is a little more expensive, but eventually CFLs will give you more for your money. Also, CFL bulbs are just better for the environment and they save energy.
In order to put out less carbon, I am slowly going to change every light bulb in my house when they burn out. I will go from incandescent bulbs to CFLs. Hopefully, the overall outcome of this will be that I put out less carbon and not spend more money than necessary.

    Hello, today in class I had to find out how much carbon I emit per year. I thought that I would emit the same amount of carbon as an average person, but instead I have gone almost as 3 times the amount more! Most of the carbon is produced in my home, where I think is produced from the many incandescent light bulbs I have turned on throughout the day.

Ngozi N- USA, Oct. 9, 2013

Hello! My name is Ngozi and I’m from the US. My total was 8258 kg of CO₂ per year, compared to the average of 23400 kg of CO₂ per year for my region. As you can see, my carbon footprint total was pretty much below average, which didn’t surprise me. The most is produced from Home and the least comes from Purchases. The Purchases part didn’t surprise me at all. I hardly shop, and in the rare instances that I do, it’s usually recycled or out of necessity. I’m also very cautious of what I use, and what I need and don’t need. I recycle mostly at school and tend to reuse more at home.

However, home is where the most CO₂ is produced for me. As much as I want to say it didn’t, this calculation really did surprise me at first, but when I reflected on it, I quickly realized the problem. The AC is always on in my house! I’m not a big fan of the cold, but when it comes to whether the AC should be on or off, it’s two of them against one of me. I’m usually left wrapped up in a blanket.

I really believe that the period of time we leave on the AC heavily contributes to the amount of CO₂ that not only I produce each year, but also that my household produces. Cutting down the amount of time the AC is on and also the amount of time the lights are on would definitely make a positive impact on my carbon footprint. For my family, these are the two main contributors that have to be cut down. The only problem now is getting the rest of my family on board!
