Taiwan's high-temperature hot spring area often use the diversification, such as: bathing, cooking, agricultural irrigation. The development of products can reduce the use of gas, electricity and other fuel use, also reduce the generation of carbon emissions. This study will be informed by telephone means of sales of eggs, the hot spring eggs mature time to calculate the amount of electricity, and estimate the required amount of carbon emissions. This study shows that the highest sales of Jinlun hot spring eggs for weekdays can be sold 400, the holiday is as high as 1,000, sales at least is about weekdays 2-3 times. Chihben hot spring area on normal day sales of about 10-65, holiday 20-150, holiday sales of about 2 times the normal day. Hatonozawa hot spring on normal day 39, holiday 181, holiday sales of about 4.5 times the normal day. The estimated carbon emissions from cooking a hot spring egg are between 0.10 and 0.15 (kgCO 2e ). If the number of days on weekdays is 255 days and the holiday is 110 days, it is estimated that the use of hot spring to cook the eggs process, each hot spring industry can reduce carbon emissions each year. The results show the carbon reductions of Jinlun, Chihpen and Jiuzize Hot Springs will reach 27,982, 7,320 and 4,564 (kgCO 2e , respectively.
