低碳视角下绿色交通发展路径与政策研究

为给我国绿色交通规划目标和管理政策的制定提供决策支撑,在低碳视角下,设置面向2030 年和2050 年的基准情景、强化减排及2℃近零排放三种情景,分析不同情景下交通运输碳排放的变化趋势。研究结果表明：（1）交通运输CO2排放总量呈快速增长趋势,只有采取强有力的政策和手段,才有可能在2030 年前后使碳排放达到峰值;（2）推动交通能源系统的清洁化和低碳化,加快运输结构调整,提高运输组织效率应是行业绿色低碳发展的重点关注方向;（3）技术进步是推动减排的核心手段之一;（4）要转变消费观,推动绿色低碳交通的生产生活方式。     

缓解城市交通拥堵的CO2减排效益评估方法研究

城市交通拥堵是导致城市交通碳排放快速增长的重要原因. 分析影响城市交通碳排放的关键因素,收集现有碳排放因子,开展车辆排放测试,建立不同道路类型和服务水平的城市交通碳排放因子数据库. 对ASIF 方法进行改进,基于城市交通拥堵的分类方法,提出中观尺度的城市交通缓堵减排效益评估方法和模型. 以成都市为例,开展城市调研、数据采集与分析、模型运算,评估成都全年城市交通的碳排放总量,其中,交通拥堵的碳排放占48.2%. 设置4种正向减排发展情景和3种反向恶化发展情景,分析不同情景下的碳排放效果.     

Prioritizing mechanism of low carbon shipping measures using a combination of FQFD and FTOPSIS

As technical incentives, Ship Energy Efficiency Management Plan and Energy Efficiency Design Index, became the guidance for shipping companies in low-carbon shipping (LCS) integration. Despite the diversity of LCS measures, a mechanism to prioritize them is still urgently required from the view of shipping stakeholders. This paper developed a LCS measures prioritization mechanism for vessels relied on the combination of Fuzzy-based Technique for Order Preference by Similarity to Ideal Solution (FTOPSIS) and Fuzzy Quality Function Deployment (FQFD) so as to facilitate the treatment of uncertainties, thus realizing effective quantitative analysis of the LCS measures. Four performance aspects of LCS measures including ecological, reputation and competitive advantage, economic, and certainty level were analyzed and used for suitableness assessment, whereas weights of prioritizing criteria were determined by FQFD, alternatives were prioritized by FTOPSIS to build up a list of ranked LCS measures. The illustration example based on collected data of six alternatives was carried out to validate the feasibility of the methodology in prioritizing LCS measures. The outcomes can be used either as a stand-alone technique for prioritizing or as part of an integrated decision-making method for evaluating the effectiveness of chosen LCS measures.     

Assessing carbon footprint and energy efficiency in competing supply chains: Review - Case studies and benchmarking

This article compares the energy consumption and CO₂ emissions of supply chains in Belgium, France and UK looking in particular at, jeans, yogurts, apples, tomatoes and furniture. We use a generic methodology that allows comparability across the supply chain of products, supply chains, and countries. Our benchmarking show relatively high emissions for maritime transport and the consumer leg, while logistics activities such as storage and road freight exhibit relatively low emissions. The influences of distance, retail type, area density and consumer behaviour are also examined.

贵州省道路客运交通运输碳排放清单研究

本文以贵州省道路客运交通运输中出租车和公交车作为研究对象,采用IPCC能耗统计法计算客运交通运输温室气体中CO2的排放、在NEDC工况下对温室气体CH4、N2O排放进行核算,建立了2017年贵州省交通道路运输温室气体碳排放清单。结果显示,贵州省道路客运交通中出租车万人均碳排放量为公交车的2.67倍。CH4排放的主要来源于天然气为燃料的公交车,N2O排放的主要来源于汽油为燃料的出租车。
