Green information technology systems (Green ITS) are proposed as a strategy to reduce greenhouse gases (GHGs) emissions and other environmental impacts while supporting ecological sustainable development. The Green ITS concept combines both Green information technology (IT) and Green information...

Across many developing nations, such as Rwanda, the absence of electricity has significantly reduced the economic impact of rural communities on their surrounding communities. A common practice in some locations is to process farm products using locally invented machines, which diminishes the...

Across many developing nations, such as Rwanda, the absence of electricity has significantly reduced the economic impact of rural communities. A common practice in some locations is to process farm products using locally fabricated machines, which diminishes the quality and quantity of...

We develop a method for finding optimal greenhouse gas reduction rates under ongoing uncertainty and re-evaluation of climate parameters over future decades. Uncertainty about climate change includes both overall climate sensitivity and the risk of extreme tipping point events. We incorporate...

A life cycle assessment of sugar produced in South Africa evaluates the environmental impacts and energy consumption of the different life cycle phases of sugar production. The system studied includes sugar cane farming, fertiliser and herbicide manufacture, cane burning, sugar cane...

We investigate the effect of biofuels on land use change through a case study of U.S. corn production. Currently, agricultural models are used to estimate the effect of biofuel production on crop production and, correspondingly, land use change. As biofuel production grows, the models can...

We develop a stylized model to investigate the impact of financial options on reducing carbon permit price volatility under a cap-and-trade system. The existence of an option market provides a mechanism to hedge the uncertainty of future spot prices and is a stimulus for investment in carbon...

We investigate the causes behind the underwhelming adoption of voluntary Time-of-Use (TOU) tariffs in the residential electricity market. TOU tariffs are deployed by utilities to better match electricity generation capacity with market demand by giving consumers price incentives to reduce their...
