摘要

气候变化包括由人为温室气体排放导致的全球变暖,以及由此导致的天气模式的大规模变化。伊朗德黑兰拥有1300万人口(2017年),每天产生约1.3万吨城市固体废物,每年产生470万吨。本研究采用生命周期评估(LCA)方法计算了德黑兰废物管理不同情景下的所有排放量。IWM模型用于LCA的第二阶段。结果表明,温室气体(GHG)排放量最高,在第一、第二和第三种情景下分别为960万吨、320万吨和270万吨。利用IPCC的报告和生命周期清单的结果,计算了基于二氧化碳当量的情景的社会成本分析。与第一种和第二种情景相比,第三种情景的社会成本分别降低了71.8%和17.2%。因此,根据温室气体在全球变暖中的重要性,在废物管理系统中采用第三种方案可以有效地减少德黑兰的温室气体。

Social Cost of CO2 emissions in Tehran Waste Management Scenarios and select the scenario based on least impact on Global Warming by using Life Cycle Assessment
Climate change includes global warming driven by human-induced emissions of greenhouse gases and the resulting large-scale shifts in weather patterns. Tehran, Iran, has a population of 13 million (2017) and produces about 13,000 tons of municipal solid waste per day and 4.7 million tons annually. This study used the life cycle assessment (LCA) method to calculate all the emissions in different scenarios for Tehran's waste management. The IWM model was used for Phase II of the LCA. The results of the proposed scenarios showed that the highest emission was from greenhouse gases (GHG), which were9.6, 3.2, and 2.7 million tons in the first, second, and third scenarios, respectively. The IPCC reports and the results from the life cycle inventories were used to calculate the social cost analysis for the scenarios based on the CO2 equivalents. The third scenario caused a 71.8% and 17.2% reduction in terms of social costs compared to the first and second scenarios, respectively. Thus, according to the importance of greenhouse gases in global warming, employing a third scenario in the waste management system could effectively reduce greenhouse gases in Tehran.
