1 environmental challenges energy consumption and efficiency in ports and terminals Gordon Wilmsmeier Infrastructure Services Unit (ISU), Natural Resources and Infrastructure Division (NRID) UN-ECLAC, Santiago, Chile Seminario Transporte Aéreo CEPAL June, 2015

2 let me take you to a journey to another mode to discover differences and similarities

3 global changes and current trends the challenge measuring energy consumption emerging issues

4 global changes and current trends trade structure and logistics chains

5 demand: How is China s meat consumption related to energy consumption container terminals?

9 why should energy consumption be discussed in ports/ terminals? increasing energy costs investment into energy infrastructure sustainability of infrastructure and logistic chains infrastructure investment efficiency and competitiveness carbon footprint

17 goal creating an uniform and globally accepted terminal operation terminology and statistical method to measure energy performance identifying and rewarding best practices annually measuring container terminal performance in terms of energy consumption and efficiency container terminals are multi product operations differentiation necessary between: container types (i.e. dry, reefer) transhipment and impo/expo cargo full and empty Source: Spengler and Wilmsmeier 2015

28 energy consumption and efficiency in logistics chains general goal: Reduction of SCOPE 3 ( Supply Chain Emissions) = Supply Chain Emissions = 74% of emissions on average(ghg Protocol) Though 95% of the exports from South America are exported via ports: Our approach: Reduction of carbon footprint in Ports are neither included in carbon footprint calculations of logistic chains logistic chains via nor are increased they analysed energy efficiency? +? =? Companies have to start to collaborate along the whole logistics chain with all stakeholders involved

31 a developing and needed research agenda developing proposal of energy efficiency indicators for terminals simulation of future energy consumption in infrastructure modelling of energy consumption pattern of maritime supply chains (esp. perishables) analysing policy tools to improve promote energy efficiency in infrastructure analysing the need/possibility for energy indicators in future concession contracts

32 many issues are about awareness, knowledge sharing, collaboration and cooperation the need to understand the why s and how s to make the right policy decisions and to shape the future of our mobility contact: Gordon Wilmsmeier gordon.wilmsmeier@cepal.org
