My carbon footprint
I calculated my carbon footprint using the Cool Climate Network calculator of Berkeley education (http://coolclimate.berkeley.edu/carboncalculator). I adopted this program because it is easier to use especially for students. For instance, it has the tabs for the information that is required to get the carbon footprint; in the introduction, I had to fill in my zip code (07304), the calculator has other options for the city, the county or the state. I also had to key in the number of people in my household (3), and the range of the gross annual household income ($ 100,000-199,999). To this level, the calculator indicated that I had a total of 77.4 tons of carbon dioxide per year; the calculator showed that the footprint obtained was similar to other households in Lake Hiawatha, New Jersey 07034 with three people and same income. Then I moved to the travel tab and keyed in my information; the value here was 14.4 tons of carbon dioxide per year; the value here was 40.9 percent better than the other households in my area with three people and an annual income that is similar as that of my household. On housing, I had 16.4 tons of carbon dioxide per year with 22.5 percent better than my neighbors. The Total Food yielded 10.1 tons of carbon dioxide per year with 31.4 percent worse, and a total shopping of 21.8 tons of carbon dioxide per year with 9.6 percent better than my neighbors (Cool Climate Network, n.d).
My total footprint is 62.8 tons of carbon dioxide per year that is 18.9 percent better than my neighbors with three people and similar income. I can say that I am surprised that the value is higher than what I had anticip...
