After using the carbon calculator resources provided, it seems that I contribute to carbon emission mostly through travel. Even though I drive my car just once a week on average, owning a vehicle that runs on gas clearly hurts the environment a great deal. I was also surprised to see how much air travel played a factor. Over the past year, I have taken several round-trip flights for weddings, and including that in these calculations caused the biggest spike in my carbon output. To make the proper reductions, I am willing reduce short-distance car travel whenever possible and consider alternate forms of transportation for long-distance travel.
