The looming challenges of global warming and peak oil have begun to spur the development of alternatives to our current petroleum based transportation system. However, before these alternatives are implemented on a significant scale, it is important to assess these technologies with a broad lens and ensure that they will not introduce more problems than they will solve. In this study, a life cycle...
In this paper, we propose a methodology for real-time characterization of the operational state of a subsystem, device or process in an ecosystem, with the goal of improving its sustainability. The objective is to re-describe the operational state, identified by a set of relevant sensor measurements and other parameters, in terms of known operational patterns. Each pattern is also associated with...
International trade is recognized as a mechanism to optimally allocate resources including capital, labor, and materials at the global scale. Recently there has been increasing interest in the embodied environmental impacts of international trade, especially in emissions embodied in trade. Focusing on the environmental side, it is standard to ignore the environmental overhead of the labor (EOL), environmental...
In traditional process design, engineers aim to use man-made technology to solve practical problems. However, the resulting designs are often directly or indirectly dependent on ecosystem goods and services and this is often ignored. Neglecting these invaluable services has led to unsustainable practices through overexploitation of ecosystems. In addition, narrowly focusing on technological solutions...
Understanding the total life cycle CO2 impacts of different types of products and operations has been a subject of significant interest recently. Total life cycle impacts include not just the CO2 generated from the manufacture of a product, but also from the product's use and from the manufacture of all the inputs that go into creating the product. In theory, understanding this total impact can help...
