GHG emission reduction is one of the key environmental problems for the sustainable development discussion in the 21st century, because it is closely related to energy use and bulk material flows. Concrete and binding targets for reduction of greenhouse gas (GHG) emissions for Annex-1 countries are now agreed to in the Kyoto protocol. Emissions in the European Union will be reduced by 8% in the...

population growth can greatly impact on greenhouse gas emission pattern in the future. considering the importance of population growth in climate change studies, the present research concentrates on the population growth of the middle east in the late 21th century based on the iiasa population scenarios. under the projections of a1-b1 scenario, the world’s population will grow up to 8.7 billion...

The Copenhagen Accord reiterates the international community's commitment to 'hold the increase in global temperature below 2 degrees Celsius'. Yet its preferred focus on global emission peak dates and longer-term reduction targets, without recourse to cumulative emission budgets, belies seriously the scale and scope of mitigation necessary to meet such a commitment. Moreover, the pivotal impor...

Traffic simulation systems are widely used for the prediction of certain effects like traffic jam formation or the analysis of performance for new traffic light systems. Fuel consumption and CO2 emissions are important measurements. This work integrates a physical model for fuel consumption into a microscopic traffic simulation system for urban scenarios. The parameters of the model are discuss...

Scenarios are alternative images of future and are useful tools for learning about complex environmental systems behaviour. The objective of this study is to generate future socio-economic cum emissions scenarios and projections for carbon emissions in each scenario for the time period up to 2030. There are not many studies available in India on scenario construction though different government...

This study describes a simple parameterization to estimate regionally averaged changes in surface ozone due to past or future changes in anthropogenic precursor emissions based on results from 14 global chemistry transport models. The method successfully reproduces the results of full simulations with these models. For a given emission scenario it provides the ensemble mean surface ozone change...

Increasing electric vehicles usage, as a promising solution for environmental issues, might have unexpected implications, since it entails some changes in different sectors and scales in energy system. In this respect, this research aims at investigating the long-term impacts of electric vehicles deployment on Iran's energy system. Accordingly, Iran's energy system was analyzed by LEAP model in...

To explore the relationship between tropospheric ozone and radiative forcing with changing emissions, we compiled two sets of global scenarios for the emissions of the ozone precursors methane (CH4), carbon monoxide (CO), non-methane volatile organic compounds (NMVOC) and nitrogen oxides (NOx) up to the year 2030 and implemented them in two global Chemistry Transport Models. The “Current Legisl...
