A study was conducted to determine whether sorghum silage can be a valid alternative to corn silage in lactating cow rations in terms of enteric CH4 production and global warming potential (GWP) per milk unit. Diets containing corn (CS), whole plant grain sorghum (WPGS) or forage sorghum (FS)...

The purpose of this study is to investigate the temporal aspects of the social cost of greenhouse gases. We are particularly interested in the interaction between time of emissions, discounting and type of greenhouse gas (where different greenhouse gases have different atmospheric life time). We...

A rigorous mathematical approach is developed for optimization of sustainable single-effect water/Lithium Bromide (LiBr) absorption cooling cycles. The multi-objective formulation accounts for minimization of the chiller area as well as the environmental impact associated with the operation of...

With life cycle assessment (LCA) methodology, a life cycle model of coal-based dimethyl ether (CBDME) as a vehicle fuel is established for China. Its life cycle from well to wheel are divided into three phases. They are feedstock extraction, fuel production and fuel consumption in vehicle. The...

The optimal design of an energy-intensive process involves a compromise between costs and greenhouse gas emissions, complicated by the interaction between optimal process emissions and supply chain emissions. We propose a method that combines generic abatement cost estimates and the results of...

Multi-gas approaches to climate change policies require a metric establishing ?equivalences? among emissions of various species. Climate scientists and economists have proposed four classes of such metrics and debated their relative merits. We present a unifying framework that clarifies the...

We address the issue of the design of climate policy in a dynamic, multi-greenhouse gas context. Despite well-established shortcomings, the Global Warming Potential (GWP) is the most commonly used index to compare greenhouse gases. We first review the shortcomings of the GWP from an economic...
