Estimations of the contribution of international shipping to greenhouse gas emissions

Maritime transport is the backbone of world trade and globalization. Twenty-four hours a day and all year round, ships carry cargoes to all corners of the globe. This role will continue to grow with the anticipated increase in world trade in the years to come as millions of people are expected to be lifted out of poverty through improved access to basic materials, goods and products. World trade and maritime transport are, therefore, fundamental to sustaining economic growth and spreading prosperity throughout the world, thereby fulfilling a critical social as well as an economic function.

Maritime transport will be indispensable in a sustainable future global economy, being the most energy efficient mode of mass cargo transport; in 2012 ships carried about 9.2 billion tonnes of cargo and over 2.1 billion passengers. Consequently, these environmental, social and economic dimensions of maritime transport are equally important and should be fully recognized in any strategy, policy, regulatory framework or action.

燃煤电厂细粒子排放特征研究 (Emission Characteristics of fine particles from coal- fired power plants)

摘要 
当前我国区域灰霾污染突出,燃煤电厂因排放大量的细粒子而备受关注。本文从粒径分布、无机组分和有机组分等方 面,系统研究和总结了燃煤电厂细粒子排放特征。结果表明,我国燃煤电厂除尘和脱硫设施除去烟尘颗粒物中大部分粗粒子,但对细 粒子的脱除能力则很弱;As、Pb 和 Zn 等无机组分,以及 OC 和 PAHs 等有机组分易在细颗粒上的富集;与电力行业大气污染控制发展 相比,排放特征研究明显滞后,迫切需要开展工作。

基于改进的主成分回归模型的碳排放预测研究 (Carbon emission forecast using improved Principal Component Regression (PCR) model)

摘 要
为分析影响碳排放的主要因素,本文引入主成分分析理论,多元线性回归模型来考察影响碳排放的人文、经济、能源等 因素与碳排放之间的相互关系,进一步对其影响因素进行主成分多元回归建模,并就未来的碳排放及其强度展开预测。结果表明:在 所考察因素中,能源消费总量与碳排放的关系最为紧密;其次是 GDP 和人口总量。在结构指标中,工业化率和化石燃料比重,这两个 因素对碳排放的影响远高于城市化率、城镇居民消费水平。对上述结果分析后,本文提出了合理控制能源消费总量和经济增速,提高 经济发展质量和服务业比重,促进新能源产业发展等政策建议。最后,基于情景设置,本文运用主成分回归方程对我国 2020 年碳排 放总量及其强度进行预测。

低碳经济下城市能源需求与碳排放情景分析 以河南省济源市为例 ( Scenario analysis of urban energy demand and carbon emission in the context of lowcarbon economy: the case of Jiyuan in Henan province)

This brief is submitted in the Chinese language. The full brief could be accessed through the below link. Your comments could be in either English or Chinese.

摘要  
以低碳经济为背景,探讨城市在能源和碳排放约束条件下未来的可能发展路径,将河南省济源市作为研究开展的案例城 市,基于情景分析法和“脱钩”概念,展示了济源市的低碳发展图景。认为:第一,济源市的能源需求若保持现有高速增长趋势是不 可取的,低碳情景下和强化低碳情景下能源需求总量和增速有明显改善;第二,尽管在最严格的情景下,济源市的人均能耗预测值仍 然高于国际国内其他城市的预测,但由于其资源禀赋特征等问题,还是存在着一定挑战;第三,济源市的经济增长依靠工业生产拉 动,对于工业占比为绝对主导的这类城市而言,发展低碳经济的着力点和潜力释放应在传统产业格局的升级改造上。
