溫室氣體減量是近來國際間所重視的問題，雖然排放的大宗來自能源與工業，然農業，林業和其他土地利用所產生之排放量仍佔第二大貢獻（24％），此一部分即與食物有關。根據2005 年學者之研究，若以每一觀光人日平均吃三餐來計，一年就有750 萬億餐，即便個人單日飲食所產生的碳排放不是很大，但如果按這樣的比例來算，飲食所可能產生的碳排放則不容忽視。因此本研究擬調查不同旅遊飲食型態及其飲食內涵，與溫室氣體之關係，研究結果可作為未來溫室氣體減量管理之參考。 The reduction of the Green House Gas (GHG) is one of the most important issue in international. Though emissions are largely from energy and industry, emissions from agriculture, forestry and other land uses account for the second largest share (24%), the sectors are associated with dairy diet. According to the study, almost 25 billion tourist days were spent in 2005. At an average of three meals per tourist per day, this corresponds to roughly 75 billion meals per year, or just over 200 million meals per day. Therefore, we cannot neglect the fact that the diet might have the potential to produce the vast majority of GHG. This study was to investigate the relationship between dietary patterns, dietary contents and GHG and the results could serve as a reference for the future management of greenhouse gas reduction.
