Getting Hitched Eco-Style

So my project idea is quite personal: greening my wedding. There is no date set yet, and I am certainly not getting married this semester, so my project will not show the end result. Instead I am going to do a lot of research and a lot of planning. I want to see if I can figure out the average carbon footprint of a typical wedding and see if, at the end of the semester, I can come up with a way to determine what the carbon footprint of my proposed wedding would be based on my eco-friendly planning. I will break wedding stuff into categories throughout the course of my project (clothing one week, food the next, etc.) For each category I will describe traditional and common ways to do things and then come up with several options to make the wedding more green. I think it is important to describe several options because I am guessing there will always be much more eco-friendly options than what I ultimately decide to go with. So there you go. I am very open to suggestions!
