On-road emissions are precisely the emissions which are impacting the air quality and which need to be controlled if air quality improvements are desired. Remote sensing measures mass emissions of CO, HC, NO and smoke per kg (or per L) of fuel burned. On-road emissions are not certification emissions for new vehicles, although new vehicles measured on-road most often provide remote sensing read...

Greenhouse gas emissions from the agricultural ecosystem account for 7%–20% of the world’s total greenhouse gas emissions, while approximately 17% of China’s carbon emissions are from agriculture. In this study, based on the scientific calculation system of carbon emissions in agriculture, we calculated the carbon emissions of agriculture in the Hotan prefecture between 1999 and 2013 and analyz...

CO(2) emissions from the burning of fossil fuels are the primary cause of global warming. Much attention has been focused on the CO(2) directly emitted by each country, but relatively little attention has been paid to the amount of emissions associated with the consumption of goods and services in each country. Consumption-based accounting of CO(2) emissions differs from traditional, production...

the increase of greenhouse gases (ghg) in which co2 emissions constitute the principal component, is of major environmental problems of all societies. economic growth impels intensive use of resources and as a result, more residues and wastes thrown in the nature that could lead to environmental degradation. this article tries to trace the eventual relationship between trade openness and enviro...

In this study, a decomposition and emissions matrix is developed to identify the roles (giver or taker) played by the sectors in the greenhouse gas emissions for the economy of Beijing in China. Our results indicate that services were the most important emitter if we consider the total (direct and indirect) emissions. In addition to Construction, Scientific studies and technical services and Fi...

Most published research concerning the environmental impacts of broiler poultry production is limited to assessments of on-farm gaseous and nutrient emissions. Here, ISO-compliant Life Cycle Assessment was used to predict the broader, macroscale environmental impacts of the material and energy inputs and emissions along the US broiler supply chain. It was found that feed provision accounts for ...

Vehicle tailpipe emissions are major sources of air pollution and greenhouse gases. In addition to the ongoing efforts on emissions reduction, we believe there is a need to explore an innovating approach in which drivers routing decisions are influenced to minimize emissions and fuel consumption. In order to evaluate such transportation systems, we develop environmental traffic assignment model...

EKC scenarios presented by Dasgupta and others (2002) are, with regard to the analytical framework of the Environmental Kuznets Curve (EKC), applicable in Asia to representative environmental indices, such as sulphur emissions and carbon emissions. To carry out this study, a generalized method of moments (GMM) estimation was made, using panel data of 19 economies for the period 1950-2009. The m...

The Sierra report proposes a methodology for states to use to demonstrate that their Inspection and Maintenance (I/M) programs are obtaining emissions reductions similar to those estimated by the MOBILE emissions factor model. The proposed methodology involves comparing fleetwide test average emissions of a state I/M program with those of a benchmark program (Sierra suggests using the Arizona I...

The paper outlines the Emission and Biofuel Directives relating to CO2 emissions in cars and the fiscal penalties incurred by manufacturers failing to meet targets. The effect on emissions of the biofuel directives are quantified through a test programme which measures emissions from a turbo-charged diesel engine using a range of biodiesel fuels, using standard diesel fuel to obtain a compariso...
