今年1月,奥地利、波兰、希腊等欧盟成员国的国家注册系统遭黑客入侵,被盗去约2870万欧元的200万碳排放额,市场交易被迫暂停一周。这一事件的发生,令外界对欧盟碳排放交易体系安全性的质疑再度抬头。而欧盟官方不会公开承认交易体系存在问题,因为将航运业纳入欧盟碳排放交易体系一直是布鲁塞尔坚定不移的选择。那么,航运排放交易体系是否可行呢? 相似文献

考虑对供应商和制造商有碳排放限制,研究供应商参与零部件回收再制造的供应商和制造商两级回收闭环供应链.比较分析了对供应商和制造商有无碳排放限制两种情况下产品的零售价格、批发价格以及制造商和供应商的利润.分析表明:制造商在有无碳排放限制两种情形下的零售价格之差与回收率有关;供应商在有无碳排放限制两种情形下的批发价格之差不仅与回收率有关,还和政府的碳排放限制政策、产品市场需求状况、回收产品无效零部件比例以及通过回收再制造产品的碳减排系数有关.最后,通过数值算例验证文中的结论. 相似文献

根据物流行业的特点并结合江苏省的实际情况,从物流业总体情况、交通运输、信息及人力资源等几大方面选取了8个投入指标,并以物流业增加值及货运汽车碳排放量为输出指标,构建出江苏省碳排放效率评价体系。针对传统方法的局限,利用主成分分析法对评价指标进行降维,并结合非期望产出处理等方法,再运用DEA方法对江苏省物流业碳排放的效率进行评价。研究表明,2010年江苏省13个城市中,南京、无锡等6个城市在综合效率、纯技术效率及规模效率上都达到了DEA有效,规模报酬不变,碳排放效率是最好的;而其他几个城市没有达到DEA有效,因此对这些城市的松弛变量分布进行分析并有针对性的提出了改善建议,旨在促进其物流业的可持续发展。 相似文献

To ensure the successful implementation of China’s Belt and Road (B&R) Initiative, it is essential to enable the real-time monitoring of containers’ locations, prevent theft during cargo delivery, ensure more efficient logistics management and reduce carbon emissions. For this, it is vital to have an economic and effective system to track and control containers across multiple countries. However, this requirement cannot be met by today’s container tracking systems because they are either limited within the borders of each country or expensive to employ internationally. This study thus presents a framework for an IoT-based container tracking system that enables users not only to grasp the international flow of container movement with one check but also to achieve smooth cross-border procedures. To verify the system’s performance, an empirical test was made for an actual container shipped from Korea to Poland. The test results showed that the system could successfully track the location of the container in real time across international borders. Last, this study discusses the policy development and international cooperation that should take place to enable the introduction of this container tracking system. 相似文献

长江上游船舶大型化趋势明显,评估其对典型污染排放的影响对航道建设规划具有重要意义。收集计算长江上游船舶吨位、船舶交通流、船舶燃油消耗及典型污染物排放等数据,分析了长江上游船舶大型化对典型污染物排放的综合影响。结果表明:1)2008—2019年长江上游三省一市船舶平均吨位从249 t增加到874 t,船舶流量显著减小,货运量显著增加。2)上游航道等级由Ⅳ级提升至Ⅲ级,理想状态下船舶单位周转量典型大气污染排放减少31.2%。3)水路货运周转量增加导致船舶污染总排放增加,但基于船舶平均吨位大型化计算,2008—2019年水路运输替代陆路运输的污染物减排量约190万t,较船舶平均吨位不变状态下的污染减排量增长约7.7%。4)建议提升长江上游航道等级至Ⅱ级,进一步推动船舶大型化发展,相对于Ⅲ级航道船舶单位周转量典型大气污染排放可减少36.4%,促进交通运输行业实现“碳中和”目标。 相似文献

By virtue of its coastal and insular character, Greece undoubtedly holds a leading position in Europe with regard to domestic passenger shipping. In the quest to improve economic competitiveness and curb carbon emissions in Greece, the energy efficiency and carbon footprint assessment of domestic passenger shipping has so far attracted little attention in comparison to other energy consumers, including other modes of transport. In the current work, energy and carbon efficiency of domestic passenger shipping in Greece during the decade 2001–10 is expressed and estimated through the associated intensity terms, i.e. the consumed energy and carbon dioxide emissions per unit of transport work performed. The energy and carbon efficiency assessment is facilitated through comparisons with relevant shipping operations in Europe and other regions of the world. Furthermore, the influence of the market’s seasonal and spatial characteristics is also examined. Finally, the analysis of energy efficiency provides the means for assessing the influence of fuel expenditure upon the overall cost of the supplied services. 相似文献

The objective of this research is to establish an integrated framework for carbon footprinting (CF) at container seaports (CSs). Three methodological approaches are used in this research: the multiple case study to choose suitable evaluation methods, the case study for verification of the proposed framework, and the quantitative method to calculate the emissions. The proposed integrated framework consists of five modules: policy components, sources structure, input data, emissions estimation and mitigation strategies. The effectiveness of the integrated framework is demonstrated through the practical application in Qingdao Port in China. The case study results in the detailed estimation of CO2 emissions and detects the problem of data collection and data accuracy for CF and the necessity of stakeholders’ cooperation. The integrated framework serves to evaluate, analyze and control CO2 emissions from the CS operations. 相似文献
