World Highways - Roads for the future Speakers at the 3rd European Road Congress looked at ways of preparing infrastructure to cater for future demands. Patrick Smith reports Road accidents in Europe can be reduced substantially, but vehicles will have to make more use of technology, and they will cost more. The problems will not be made any easier with the knowledge that road transport is set to double between 2040 and 2050. These were just some of the forecasts made at the 3rd European Road Congress, held in Brussels, Belgium, a key road sector event, which attracted more than 100 participants. Delegates reaffirmed that only placing road infrastructure at the top of the agenda would result in the sector matching the tough expectations placed on it by society. In the future, roads will have to be more resistant, more 'intelligent', cheaper to build and to maintain and ever safer for their users, as "has always stressed throughout the years by ERF-IRF BPC." "It is not just a dream. Flanders in Action Sustainable transport

An Introduction to Life Cycle Environmental Assessment About the Course Paper or plastic? Local or imported food? Life cycle assessment (LCA) is a fundamental method for assessing the environmental impacts of products and technologies from a "cradle to grave" systems perspective. The course will provide an introduction to LCA methods and applications. Course Syllabus - The basics of energy and mass flows and exchanges with the environment - Working with unit processes and unit process inventory data- Study design: goal definition, system boundaries, and functional units - Compiling the data: life-cycle inventory methods (process-based and input-output methods) - Understanding impacts: life-cycle impact analysis for land, air, water, and health - Building a simple LCA model using spreadsheet software- Results interpretation and reporting Recommended Background Suggested Readings All required readings will be publicly available with links posted on the course website.

Khan Academy Manufacturing inefficiency Modern manufacturing methods are spectacularly inefficient in their use of energy and materials, according to a detailed MIT analysis of the energy use of 20 major manufacturing processes. Overall, new manufacturing systems are anywhere from 1,000 to one million times bigger consumers of energy, per pound of output, than more traditional industries. In short, pound for pound, making microchips uses up orders of magnitude more energy than making manhole covers. At first glance, it may seem strange to make comparisons between such widely disparate processes as metal casting and chip making. "The seemingly extravagant use of materials and energy resources by many newer manufacturing processes is alarming and needs to be addressed alongside claims of improved sustainability from products manufactured by these means," Gutowksi and his colleagues say in their conclusion to the study, which was recently published in the journal Environmental Science and Technology (ES&T).
Sustainable Transportation Source: adapted from UK Department of the Environment, Transport and the Regions, 1999. The concept of sustainable transportation is intricately linked with the development of sustainable transport modes, infrastructures and logistics. Three major dimensions are considered for such a purpose: Environment. A reduction of the environmental impacts of transportation is a likely strategy for sustainability. Transportation significantly contributes to harmful emissions, noise and to climate changes. The matter is often that reconciling all these principles, which individually appear logical and straightforward, lead to transportation systems that are unsustainable because they are too costly and regulated.
edX - Home Energy, Sustainability, and Life Cycle Assessment Course Summary | Learning Objectives | Who Should Attend | Program Outline | Schedule | Participants' Comments | About the Lecturers | Location | Links & Resources | Updates Course Summary The purpose of this class is to address the issues of sustainability and relate them to an engineering perspective. First, we review the concept of sustainability from several points of view including economics, ecology, and business. Energy resources analysis, energy and exergy flows, balances, efficiencies, primary energy use, energy return on investment, net energy analysis, and renewable energy – all from a thermodynamic perspective. The class uses our recent book Thermodynamics and the Destruction of Resources (Cambridge University Press, 2011) and builds on these topics from a solid basis. Content Fundamentals: Core concepts, understandings and tools (30%) Latest Developments: Recent advances and future trends (25%) Industry Applications: Linking theory and real-world (30%) Delivery Methods Level
Impact Estimator | Life Cycle Assessment Software In North America, the ATHENA Impact Estimator for Buildings is the only software tool that is designed to evaluate whole buildings and assemblies based on internationally recognized life cycle assessment (LCA) methodology. Using the Impact Estimator, architects, engineers and others can easily assess and compare the environmental implications of industrial, institutional, commercial and residential designs — both for new buildings and major renovations. Where relevant, the software also distinguishes between owner-occupied and rental facilities. The Impact Estimator puts the environment on equal footing with other more traditional design criteria at the conceptual stage of a project. It is capable of modeling 95% of the building stock in North America, using the best available data. The Estimator takes into account the environmental impacts of: Complex Results in a User-friendly Format Although LCA is a complex process, the Estimator has been designed for ease of use.

Life Cycle Assessment The International Organization for Standardization (ISO) defines life cycle assessment (LCA) as the following: "Compilation and evaluation of the inputs, outputs and the potential environmental impacts of a product system throughout its life cycle" (ISO 14040: 1997). Among the tools that life cycle management (LCM) offers, LCA, or environmental balance, is one of the most comprehensive and high-performance methods. The main goal of the method is to lessen the environmental impacts of products and services by guiding the decision-making process. Regulated by the ISO 14040 series standards, LCA consists in four distinct phases: The following figure illustrates the life cycle assessment framework as described by ISO. Due to time and cost constraints, variants of the LCA method have been formulated according to the guideline principles established by the Society of Environmental Toxicology and Chemistry (SETAC). In practice, LCAs are mainly used for (Labouze et al., 1996):
