In this paper, a detailed spatial allocated emissions inventory for Cyprus is presented. Topdown and bottom-up methodologies are implemented and emissions are estimated from all anthropogenic sources for the reference year 2002 with the aid of state-of-the-art algorithms. Emission factors...

Gaseous emissions of biowaste treatment facilities have several adverse effects. In Germany, a law to collect biological waste separately was introduced in January 2015. Since then there is a discussion about greenhouse gases which could be emitted in a significant rate and exceed the positive...

Air pollutant emissions and fuel consumption of vehicles equipped with internal combustion engines are highly susceptible to the conditions of engine operation. The purpose of this research was to investigate the correlation between the emissions of individual pollutants (carbon monoxide...

Urban economic development cannot be separated from energy consumption, and energy consumption directly leads to a large number of carbon emissions. It is of great significance to study the relationship between carbon dioxide emissions and economic growth for the implementation of energy...

Investigating the spatiotemporal characteristics and factors of urban carbon emissions is essential to reduce carbon emissions and achieve dual carbon goals. In this study, we examined the change tendency of carbon emissions using the coefficient of variation, the Sen’s slope method, and the Mann...

Diesel engines cause major pollutants such as hydrocarbons (HC), carbon monoxide (CO), and oxides of nitrogen (NOx). These emissions affect environmental systems and lead to global warming and climatic change effects. These pollutants also affect humans and lead to health problems like lung cancer...

Two three dimensional Eulerian air quality models, PMCAMx and UAM-AERO are used to predict the concentrations of various pollutants in the Greater Athens Area (GAA) during the episode of June 22-26, 2003. The predicted levels of gases and aerosol pollutants are compared with measured concentrations...

The aim of this paper is to identify the factors that have influenced changes in the amount of carbon dioxide (CO2) emitted from the Greek manufacturing sector as a whole and from three representative subsectors. By means of an algebraic decomposition method the changes recorded during the period...

The severe climate problem has forced the Chinese government to put forward the goal of "carbon peak" and "carbon neutrality", and the transportation industry is a key area of carbon emission reduction. Based on this background, this paper introduces the BCC model and the Malmquist-Luenberger index...

In this paper, three-dimensional numerical simulations are used to simulate the wind flow structure over coal stockpiles of a real configuration of a power plant. Two configurations are tested for various wind directions: the first one without representing the buildings and the second one with the...

The EU Directives and legislation by worldwide environmental authorities impose constantly lower levels for the airborne pollutant emissions of internal combustion engines towards the goal of zero emission vehicles. During the last decade, engine manufacturers, refiners and fuel companies invest...

Aiming at the problems of long monitoring time, low sensitivity and low precision of traditional methods, a nano sensor for near zero emission monitoring of sulfur hexafluoride (SF6) was proposed. The characteristics of SF6 gas were analyzed. The infrared spectrum of SF6 gas was obtained by spectral...

Electricity generation is the single most important sector in which CO2 reductions are achievable, with advanced generation technologies available and the existence of a centralised production structure, if compared to the transport or the industrial sector. It is a market undergoing a radical...

Heterogeneous Catalysis and Electrocatalysis can be used very effectively on air pollution control. Air emissions coming either from mobile sources or from stationary sources, including volatile organic emissions, nitrogen oxides, hydrocarbons and carbon monoxide could be well converted to harmless...

Cement production is an energy-intensive process. Utilisation of fossil fuels is common practice in the cement industry around the world. Alternative fuel substitution rates increase every year. More specifically, 18 % of the fuel used by the European cement industry in 2006 consists of alternative...

Odour is a major concern as they are termed hazardous to the surroundings as well as life forms when they are exposed to the environment. Odour emission is also one of the indicators of environmental changes that impact the environment. Among the different sources of odour emission, in the dumping...
