Container terminals play an important role in linking regional and continental areas for the exchange of goods. Port authorities have to provide their services under competitive prices and service levels to customers. This increasing competition pushes feeder ports to improve their processes. The goal is to increase the port capacity to deal with the increasing demand for containers and, at the same time, to reduce the environmental impact and operative costs. The authors address the gap in the literature regarding alternatives for feeder ports. They analyse best practices adopted in international terminals and evaluate the implementation in feeder ports. They apply a quantitative approach using the simulation software AnyLogic. The model uses market data to analyse the vessel unloading process at the berth. Moreover, an alternative to reduce the CO2 emissions for diesel equipment is presented. A flowchart for the vessel unloading and loading operations is proposed that includes the strategies to increase capacity and efficiency of operations and the utilisation of equipment.

This paper aims to analyze the economic dimension and environmental impact of intra-EU value-added generation linked to global value chains (GVCs) through input-output analysis. For this purpose, information has been collected from TiVA (Trade in Value Added, OECD) and Eora databases for the years 2005 and 2015. From an economic perspective, the results point to a strengthening of the value-added generated within Factory Europe. From an environmental perspective, all EU28 members have reduced their exports-related impacts in intensity-emissions terms, but not all of them in the same degree. An approach to the environmental Kuznets curve (EKC) has also been carried out through a panel data model. The results show a positive impact of the participation in intra-EU value chain (Factory Europe) on CO2 emissions per capita. Further, an inverted U-shaped curve for CO2 emissions is found for the period 2005–15. In this sense, European economies with lower development levels (many Eastern and Southern countries) seem to be still on the rising segment of the curve, while the more developed ones seem to be on the decreasing segment. These results highlight the need to design global monitoring and prevention mechanisms to tackle growing environmental challenges and the need to incorporate specific actions associated with the GVCs activity.

Container terminals are the main hubs of the global supply chain but, conversely, they play an important role in energy consumption, environmental pollution and even climate change due to carbon emissions. Assessing the environmental impact of this type of port terminal and choosing appropriate mitigation measures is essential to pursue the goals related to a clean environment and ensuring a good quality of life of the inhabitants of port cities. In this paper the authors present a Terminal Decision Support Tool (TDST) for the development of a container terminal that considers both operation efficiency and environmental impacts. The TDST provides environmental impact mitigation measures based on different levels of evolution of the port’s container traffic. An application of the TDST is conducted on the Port of Augusta (Italy), a port that is planning infrastructural interventions in coming years in order to gain a new role as a reference point for container traffic in the Mediterranean.

The continuous growth of the international wine trade and the expansion of international markets is having significant commercial, but also environmental, impacts. The benefits of vineyards in terms of ecosystem service provision are offset by the increase in CO2 emissions generated by transportation. Denominations of Origin, as quality labels, emphasise a wine’s links to the terroir, where specific elements of culture and environment merge together. However, Denominations of Origin can also have differentiating elements as regards environmental performance. Drawing on an extended multiregional input–output model applied to the Spanish Denominations of Origin with the largest presence in the international wine trade, this study shows that wines with the greatest exporting tradition are those that most reduced their carbon footprint per litre of exported wine in the period 2005–2018, thus being the most environmentally efficient.

Abstract In this paper, a decision support approach for designing a family of environmentally benign products for a ranged set of customer requirements is presented. More specifically, we incorporate environmental issues in order to minimize the environmental impact of products without sacrificing their performance characteristics and keeping competitive prices in comparison to existing products. The example problem consists of the design of a family of environmentally benign oil filters based on a variety of oil flow rate ranges. Environmental issues are represented by Life Cycle Assessments and comparisons of the existing alternatives based on their environmental impact. Emphasis is placed on highlighting the trade-off analysis for including environmental considerations in the design of a family of products and not on the results of the problem, per se.

As global population growth continues, the rapidly increasing demand for food and the environmental impact of this demand is a growing concern. Most food in Hong Kong is imported, which has implications for the associated environmental footprint. The carbon and water footprints (CF and WF) of the average Hong Kong diet were estimated from available sources and compared to well-accepted sustainable diets to characterize environmental sustainability. The total CF was 5701.90 g CO2-eq per capita/day, and the WF was 4782.31 L per capita/day. While meat products contributed only 22% to the weight, they were responsible for 57% and 53% of the total CF and WF, respectively. The impacts of the Hong Kong diet were greater than those of well-accepted sustainable diets, possibly due to the heavy consumption of meat and the import of foods. This confirms an urgency to increase environmental awareness among Hong Kong’s consumers and make interventions toward the adoption of sustainable, plant-based diets.

This study reports on formulations and conditions for producing fly ash-based geopolymers with a view to showing that the compressive strength required for construction applications can be obtained without the addition of aggregates, sand, and/or cement. It was shown in a series of experiments constituting at least 73% fly ash that a compressive strength of up to 90 MPa can be obtained depending on the curing conditions. While high alkalinity resulted in stronger materials, the results showed about 40% savings in CO2 emissions without using sand and cement. Such materials are suited for construction applications with minimal environmental impact.
