| 摘要: | 民以食為天，但我們甚少去了解日常所食之食材種類、來源、採購及運輸方式，究竟對環境造成多少二氧化碳排放量。因此本研究透過70位消費者，實際調查其日常及旅遊過程之飲食資料，包含菜單、食材重量及食材來源，配合廣泛蒐集之文獻碳排放量資料庫，計算其溫室氣體潛勢。研究結果顯示食用進口食材將使碳排放量大增，而日常飲食之葷素碳排放量沒有顯著差異，但觀光過程葷食者之碳排放量則顯著高於素食者。推測素食者日常生活易選擇加工素料為食材，故易提高其二氧化碳排放。另外葷食者於外出觀光旅行時對飲食具有追求特別、高級之趨勢，估算約有二成五之餐食與進口食材有關。反之素食者因外出觀光旅行時則因餐館選擇性不多，反而使得飲食之選擇傾向以蔬食為主，故於觀光過程葷素二者之碳排放量有顯著差異，有別於日常飲食。本研究之重要發現為:由於觀光過程葷食族群之飲食碳排放量顯著高於日常飲食，因此若以低碳為目標，建議遊程應多提倡深度旅遊及品嘗在地風味飲食，將有助於減碳。
Food is the basic need of man, but we seldom fully understand what our food is, where it comes from, how it is purchased, and how much carbon dioxide it emits when produced or transported.Therefore, this study conducted on 70 consumers, launching an investigation into the diet they eat not only in daily life but alsoduring a trip, including what the food is, how much it weighs, and where it comes from. In addition to collecting the data of carbon dioxide emissions from lots of documents, this research makes further efforts to calculate their global warming potential. The result shows that there will be more carbon dioxide emissions if more imported foods reach the dinner table. About 25% of the meal eaten during a trip comes from another country. In terms of the meal eaten in daily life, a vegetarian diet and a non-vegetarian one make little difference in carbon emission; in terms of the meal eaten during a trip, a non-vegetarian diet emits much more carbon dioxide than a vegetarian one. In daily life, the emission of carbon dioxide has no significant difference between vegetarianand non-vegetarian; but during a trip, non-vegetarian is significantly higher than vegetarian.The reasons might include when taking a trip, a non-vegetarian is supposed to indulge himself and, therefore, tends to eat something special or luxurious; as for a vegetarian, they cannot but eat light, because there are fewer restaurants for him to choose from. On the contrary, a vegetarian tends to eat processed vegetarian food in their daily life.Based on the findings of this study, for non-vegetarians, in-depth travel and local-flavor foods are suggested, and for vegetarians, eating non-manufactured food can help reduce carbon emission. |
