Health Impacts of Power-Exporting Plants in Northern Mexico

In the past two decades, rapid population and economic growth on the U.S.–Mexico border has spurred a dramatic increase in electricity demand. In response, American energy multinationals have built power plants just south of the border that export most of their electricity to the United States. This development has stirred considerable controversy because these plants effectively skirt U.S. environmental air pollution regulations in a severely degraded international airshed. Yet to our knowledge, this concern has not been subjected to rigorous scrutiny. This paper uses a suite of air dispersion, health impacts, and valuation models to assess the human health damages in the United States and Mexico caused by air emissions from two power-exporting plants in Mexicali, Baja California. We find that these emissions have limited but nontrivial health impacts, mostly by exacerbating particulate pollution in the United States, and we value these damages at more than half a million dollars per year. These findings demonstrate that power-exporting plants can have cross-border health effects and bolster the case for systematically evaluating their environmental impacts.electricity, air pollution, Mexico

Potential for non-road modes to support environmentally friendly urban logistics

Road freight transport typically dominates in urban delivery operations. However, an increasing number of trials and commercial operations have started in the past 10 years attempting to use non-road modes in a wide range of cities including: Paris, Berlin, Madrid, Amsterdam and others. The research establishes the existing scale of rail freight in two comparable cities (London and Paris/Ile de France) and compares the development process in terms of the stakeholders, the infrastructure and planning issues and the nature of the operations. The review considers the scope and opportunity for an increase in the use of rail for urban freight transport and assesses the barriers to its wider implementation. The research is based on a mixture of desk research examining a number of cities and their use of rail freight transport combined with some interviews with the major stakeholders. The research contains an assessment of a number of pilot projects and initiatives that can be considered together and offer important insights into the potential for changes to urban distribution operations. The findings illustrate that rail plays a more important part than is often thought but that its uptake is restricted by the complex barriers to wider implementation. Planning limits and the complexity of engaging with the range of stakeholders has made it difficult to implement rail solutions for urban freight. It is clear that some of the developments can be considered as filling a rather narrow niche function. However, it is also apparent that some initiatives have the scope for wider implementation and to contribute significantly to reducing the reliance on road freight transport in cities. The analysis will support the work of urban planners and policy makers concerned with how to reach the EU target of essentially zero CO2 urban freight by 2030. In addition, the research identifies a number of barriers that need to be overcome and proposes ways to achieve this

A review of urban consolidation centres in the supply chain based on a case study approach

The paper considers how urban consolidation centres (UCCs) can be used in the supply chain to reduce goods vehicle traffic and its associated environmental impacts, while also helping to make supply chains more responsive and efficient and thereby generate commercial benefits. The role of UCCs is presented and the various types discussed. The potential supply chain impacts of UCCs are considered. Case studies of six UCC schemes and trials are included, with their objectives, operational characteristics and impacts compared. The critical success factors associated with UCCs are identified
