We investigate the representation of emissions from the largest (Class 3) commercial marine vessels (c3 Marine) within the Community Multiscale Air Quality (CMAQ) model. In present emissions inventories developed by the United States Environmental Protection Agency (EPA), c3 Marine emissions are divided into off-shore and nearshore files. Off-shore c3 Marine emissions are vertically distributed...

The importance of energy crisis and global warming necessitates presenting strategies in order to decrease the amount of emissions as well as fuel consumption in large and complex industries such as refineries and petrochemical industries. Generally, refinery steam networks are regarded as units which consume fuel enormously. In this paper, the steam network of Tehran Oil Refinery is considered...

This paper presents a novel quantitative methodology for the evaluation and optimisation of the environmental impacts of the whole life cycle of a mega-event project: construction and staging the event and post-event site redevelopment and operation. Within the proposed framework, a mathematical model has been developed that takes into account greenhouse gas (GHG) emissions resulting from use o...

An atmospheric transport-chemistry model is applied to investigate the effects of source configuration in simulating regional sulphur deposition footprints from elevated point sources. Dry and wet depositions of sulphur are calculated for each of the 69 largest point sources in the UK. Deposition contributions for each point source are calculated for 2003, as well as for a 2010 emissions scenar...

a r t i c l e i n f o JEL classification: Q43 Q54 C68 D58 H50 H68 Keywords: Fuel prices Endogenous growth Budgetary consolidation Climate policy Dynamic general equilibrium Portugal This paper examines the influence of fossil fuel prices on carbon dioxide emissions, economic activity, and the public sector account in Portugal. It uses a dynamic general equilibrium model which highlights the mec...

The results of economic models of greenhouse gas reduction depend sensitively on the assumptions embedded in the energy scenarios chosen, both for business-as-usual and emission reduction scenarios. In this paper, some of the basic requirements of useful scientific models are reviewed and then, as a case study, applied to the MEGABARE computer model of greenhouse response in the global economy....
