BACKGROUND Evaluating the net exchange of greenhouse gas (GHG) emissions in conjunction with soil carbon sequestration may give a comprehensive insight on the role of agricultural production in global warming. MATERIALS AND METHODS Measured data of methane (CH(4)) and nitrous oxide (N(2)O) were utilized to test the applicability of the Denitrification and Decomposition (DNDC) model to a winte...

use of fossil energy provides greenhouse gases emissions and therefore global warming phenomenon and the incidence of further consequences such as expanding deserts and blasting the dust storms in the middel east, including iran. taking advantage of renewable energy is the most appropriate solution to prevent greenhouse gas emissions. ahvaz region in the southwest of with a population of 133812...

The Greenidge Multi-Pollutant Control Project is being conducted at the 107-MW AES Greenidge Unit 4 as part of the U.S. Department of Energy’s (DOE) Power Plant Improvement Initiative (PPII) to demonstrate an innovative combination of technologies that is well-suited for reducing emissions from the nation’s large fleet (~60 GW) of smaller coal-fired units. The technologies, which include a NOxO...

Scientific assessments of agricultural air quality, including estimates of emissions and potential sequestration of greenhouse gases, are an important emerging area of environmental science that offers significant challenges to policy and regulatory authorities. Improvements are needed in measurements, modeling, emission controls, and farm operation management. Controlling emissions of gases an...

Anthropogenic carbon emissions lock in long-term sea-level rise that greatly exceeds projections for this century, posing profound challenges for coastal development and cultural legacies. Analysis based on previously published relationships linking emissions to warming and warming to rise indicates that unabated carbon emissions up to the year 2100 would commit an eventual global sea-level ris...

Solid waste collection, transfer and transportation (SWCTT) is a fundamental component of solid waste management systems that contributes to both the costs and environmental emissions associated with managing solid waste. The objective of this study is to project the fuel consumption and fuel costs of SWCTT in Tehran from 2018 to 2032. A further objective is to evaluate the air pollutant emissi...

We assess the large-scale, top-down constraints on regional fossil fuel emissions provided by observations of atmospheric total column CO2, XCO2 . Using an atmospheric general circulation model (GCM) with underlying fossil emissions, we determine the influence of regional fossil fuel emissions on global XCO2 fields. We quantify the regional contrasts between source and upwind regions and probe ...
