Corporations and institutions, including the electronics manufacturing and computer services sectors have become concerned with their impacts on climate change and are participating in carbon footprint assessment and climate management discussions. Existing carbon footprint protocols classify carbon footprint into tiered ldquoScopesrdquo: direct emissions as ldquoScope 1rdquo, emissions from direct...
High-brightness light-emitting diodes (LEDs) form the basis for solid-state lighting (SSL) systems. SSL systems have the potential to reduce electricity consumption of lighting systems as they are much more efficient than current lighting technologies. One concern is that the full life-cycle energy requirements of SSL systems, including the production of the materials and LED components, may negate...
This analysis compares e-commerce versus traditional retail systems energy use and greenhouse gas emissions through a case study of a product chosen to represent the retail process. We conclude that e-commerce has lower energy use and GHG emissions for our case study.
To quantify the total life cycle environmental impacts of consumption, an economy-wide assessment of goods and services is conducted using the Economic Input-Output Life Cycle Assessment (EIO-LCA) model. This research includes an assessment of total ldquocradle to consumerrdquo impacts of consumption, utilization of US Environmental Protection Agencypsilas Tool for the Reduction and Assessment of...
This scoping study takes a broad look at how Information Technology-enabled monitoring and control systems in residences could play a role in mitigating energy use. Managing the residential sector is an important priority for addressing energy use, as use in homes represents 21% of US total energy demand, up 16% from 1994. Much energy is apparently wasted in delivering energy services not actually...
Little by little, nanotechnology has crept up on us. From a mostly academic exercise 20 years ago, it has swiftly progressed to the point where the technology is just about everywhere. However, research into possible environmental and health implications of solvents and other chemicals, including arsine and trichloroethylene, wasn't done at the birth of the industry, before such toxic substances were...
