This paper presents a vehicle’s CO2 emission reduction scheme by an ETC-assisted real-time traffic light control scheme in vehicular networks. Using Electronic Toll Collection (ETC) devices, real-time road conditions can be obtained by wireless communication between the ETC devices and the traffic lights. A decision tree classification algorithm is used to assign the changing policy for the tra...

The use of renewable energies, especially in metropolises has led to a reduction in environmental pollution and greater access to clean, renewable and sustainable energy. This paper evaluates the effectiveness of a national plan adopted by the Tehran city council for reducing air pollutions. This plan is designed to increase the share of renewable energies in residential buildings. This study a...

Decentralization development and changing urban form will increase the mobility and contribute to global CO2 emissions, in particular for developing countries which are experiencing rapid economic growth and urban expansion. In this paper, an integrated analytical framework, which can quantify the impact of changing urban form on commuting CO2 emissions, is presented. This framework simultaneou...

Concerns about climate change and the increasing cost of fossil fuels have led to interest in the development of renewable biofuel pathways for reducing greenhouse gas (GHG) emissions. The use of corn residue as a potential source of biomass feedstock for cellulosic ethanol production has been favored as cost effective. Previous research has shown that crop residue removal can cause a loss of s...

The systematic and quantitative approach on the environmental pollution is a significant challenge in highly regulated industries, such as power plants, where a large amount of waste gas including greenhouse gas must be discharged. We simulated various CO2 reduction processes and estimated the total cost of those. In this study, an environmental pollution impact is analyzed by the process opera...

in this paper, we examine the effects of thermal radiation on co2 emission and o2 depletion in an exothermic reactive slab of combustible materials with uniform surface temperature. the governing equations for the nonlinear heat and mass transfer problem are derived and solved numerically using runge-kutta-fehlberg method with shooting technique. numerical expressions for temperature field, co2...

Aircraft operations have a significant impact on local air quality, climate change, fuel consumption and noise around airports. In order to reach emission targets set by aviation agencies (e.g. ACARE), to reduce environmental impact and to ensure a sustainable future of the sector, the aviation industry is continuously investing in research and development of technologies for reducing CO2, nois...

Temperature stabilization requires that CO2 emissions be limited to less than 3 Gt Carbon equivalent, from the present level of more than 6 Gt. Despite an increase of primary energy demand by 250% in 2050 we find that a nuclear intensive scenario assuming the development of a 3000 GWe pool of PWR reactors by 2030 and of an additional 6000 GWe pool of U-Pu or Th-U reactors by 2050 would lead to ...

This paper addresses the problem of reducing CO2 emissions by applying convex optimal power flow model to the combined economic and emission dispatch problem. The large amount of CO2 emissions in the power industry is a major source of global warming effect. An efficient and economic approach to reduce CO2 emissions is to formulate the emission reduction problem as emission dispatch problem and...
