溫室氣體減量策略研擬時，若有數理分析工具提供策略可能的減碳效果，可提供決策者資訊以作選擇，本計畫目的既在建置城市層級的住宅與服務業部門減碳策略評估模型(Enduse模型)，協助新北市和臺南市政府更快速的選擇減碳策略方案。此外，於已建立之新竹市能源模型增加資源流資料，評估環境與資源策略對溫室氣體之影響。 由模擬結果顯示，無（有）溫昇情境下，臺南市2030年住宅部門減碳量相對基準情境減32%(36.8%)，服務業部門減碳量相對基準情境減20.4%(27.2%)。新北市2030年住宅部門減碳量相對基準情境減45.8%(50.3%)，服務業部門減碳量相對基準情境減29.3%(54.1%)。兩城市平均減碳成本介於-1~8.5萬元/噸CO2。若新竹市家庭採用節水設備，可避免每日0.88萬噸缺水量發生外，CO2削減量自2018年0.6萬噸增至2030年9.3萬公噸，其中省水水龍頭可節水減碳的效果最佳、省水馬桶次之。因我國資源回收執行成效在全世界是屬前段班，要再提升回收率並不容易，本計畫目前因資料有限未能計算成本，但若能自65%提升1%，溫室氣體排放量即約可減少3%。惟新竹市持續焚化外縣市的垃圾與事業廢棄物，該焚化廠之溫室氣體排放量則不一定會減少。新竹市兩台垃圾車轉為電動車，每趟約減少2.7公斤CO2e。使用電動密封壓縮車每日減少近4公噸CO2e，值得深入分析可行性。

The greenhouse gases reduction effort could be calculated by using the Mathematical analysis tools and assist decision makers to make the choice. The objective of the project is to establish the assessment model (Enduse model) for the residential and service sectors in city and analyse carbon reduction strategy in New Taipei City and Tainan City. In addition, the Hsinchu City model has established resource flows to analysis the impact of GHG on the environment and resources policies. According to the simulation results, in the absence of temperature rising scenario, the carbon emission in residential sector by 2030 in Tainan City was reduced by 32% (36.8%) in 2030, while that in the service sector was reduced by 20.4% (27.2%) relative to the baseline scenario. In New Taipei City, the carbon emission in the residential sector in 2030 was reduced by 45.8% (50.3%) and that in the service sector was reduced by 29.3% (54.1%) relative to the baseline scenario. The average cost of carbon reduction between the two cities ranges from -1 to 85,000 New Taiwan Dollar (NTD) / tonne CO2. If households adopt water-saving equipment to avoid the water shortage of 8,800 tons per day in Hsinchu City, it is estimated that the amount of carbon dioxide reduction will increase from 6,000 tons in 2018 to 93,000 tons in 2030. Among them, the Water-saving tap and toilet can achieve the best effect of water-saving and carbon reduction. If the resource recovery rate could be increased by 1% from 65% in Hsinchu City, GHG emissions can be reduced 3%. However, Hsinchu City continues to incinerate waste from other counties and the greenhouse gas emissions of the incineration plant may not decrease. The use of electric seal compression vehicles for barbage trucks can also reduce by 4 metric tons of CO2e per day. It is worth to analyse the feasibility in-depth.
