This article presents a system dynamics model to analyze the growth of cars and the effect of different policies on carbon emissions from the transport sector. The simulation model used in this work was built using the methodology of systems dynamics (SD) developed by Jay W. Forrester at the Massachusetts Institute of Technology (MIT). The model was applied to the transport sector of the city of Bogota, Colombia for a period of time between 2005 and 2050. The information used to feed the model comes from reliable sources such as DANE (National Administrative Department of Statistics) and EIA (U.S Energy Information Administration). Four scenarios were proposed that relate urban development policy and environmental policy. The main results indicate that the number of cars in Bogota can reach up to 13 million vehicles in 2050 and the projection of CO2 emissions would reach 34 million TonCO2 in the absence of an appropriate environmental policy.

This article summarizes the urban proposal of the team led by Professor Estanislau Roca, consisting of professors and students of the Polytechnic University of Catalonia (UPC), for the International Student Urban Design Competition for Shanghai Railway Station presented in 2015 at the Haishang Cultural Center in Shanghai. Harvard University, the Massachusetts Institute of Technology (MIT), Tongji University, Cardiff University, Southeast University of Nanjing and UPC participated in the competition. The UPC team won a second ex aequo prize with MIT. The UPC proposal represents the urban redevelopment of an extensive area located in the heart of the city of Shanghai, where the creation of a park comprising about 40 hectares was conceived. The park is designed to form a vast new space in the city, in an area covered by railroad tracks east of the Shanghai Railway Station, which form a great barrier that divides the Zhabei District into two disconnected parts. In the framework of the Shanghai Master Plan 2020–2040, the metropolitan scale is reflected at the local level. The proposal reinforces the continuity of green and blue through strategies that connect the new park with other existing open urban spaces and rivers. Furthermore, it enhances ecological continuity and stimulates regeneration. The project contributes to improving problems with air pollution while at the same time making the currently adopted measures more economically sustainable. Conceived from a holistic perspective, the idea is modelled on a harmonious, inclusive, friendly, smart, accessible, sustainable city networked through the state-of-the-art technology that is essential for such complex urban transformations. What is more, it rigorously pursues economic viability throughout each stage of implementation by guaranteeing that each phase finances itself while maintaining the ledger in a positive balance.

Global warming countermeasures are being taken around the world, and every country and every city is trying to minimize emissions of greenhouse gases such as CO2, on its territory. This article is devoted to the environmental policy of the Kyoto cityin the transport sector. Kyoto city is the former capital of Japan, where Kyoto Protocolwas adopted. During the study of the environmental policy, the authors identified the most important political measures based on important official documents of the local government. Not only the measures adopted by the city mayor’s office in the transport sector, were studied, but their assessment and results were examined too. However most information on eco-model cities of Japan is presented in Japanese, access to basic information is limited. Thus, this article offers new information from the original sources

Purpose Poultry production supply chains produce substantial wastes that are transformable into favorable environmental outcomes and profitable products. While overwhelming evidence supports this conclusion, scant literature is available on how such transformations are doable. Using systems dynamics, this study addresses this research gap in a national (Bangladesh) context. This study aims to contribute an integrated model for poultry supply chains that incorporate reverse flows of wastes using system dynamics (SD) engineering with empirical simulations. Design/methodology/approach This study applies SD and simulations of alternative supply chains with versus without reverse loops that transform wastes into viable products in poultry production and downstream marketing operations. This research reports on an in-depth case study of systems thinking and use of the Massachusetts Institute of Technology systems dynamics software. Data for the study are longitudinal and come from written operation records and extensive, repeated, one-on-one Interview from a large poultry plant operation in Bangladesh. Findings This study finds that several current poultry waste production problems are solvable through an integrated approach that generates viable new marketable products with substantial profitable opportunities that also contributes to reductions in industrial pollution. This study confirms that forward, backward and reverse supply chains need to be under one umbrella system to achieve economic, social and environmental benefits. Research limitations/implications This study’s SD model and outputs need additional applications in poultry supply chains in multiple countries. Applying the firm-level model that this study provides is a necessary but insufficient step toward empirical confirmation through replicating.
