Simulation Analysis of Carbon Reduction Strategy in the City and Taiwan - US technical cooperation project

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.
