Although developing countries are called to participate in CO(2) emission reduction efforts to avoid dangerous climate change, the implications of proposed reduction schemes in human development standards of developing countries remain a matter of debate. We show the existence of a positive and time-dependent correlation between the Human Development Index (HDI) and per capita CO(2) emissions f...

The reduction of greenhouse gases (GHGs), including carbon dioxide (CO2 ), has become one of the most serious issues in the world today to build a sustainable world. Digital economy have several contributions to the reduction of GHG emissions. Among them,Carbon credits is one of the most important and effect approach to reducing the amount of GHG emissions, where carbon credits are generated by...

This paper examines the ozone (O3) damages caused by nitrogen oxides (NO(x)) emissions in different locations around the Atlanta metropolitan area during a summer month. We calculate O3 impacts using a new integrated assessment model that links pollution emissions to their chemical transformation, transport, population exposures, and effects on human health. We find that increased NO(x) emissio...

Agricultural soils represent the main source of anthropogenic N2O emissions. Recently, interactions of black carbon with the nitrogen cycle have been recognized and the use of biochar is being investigated as a means to reduce N2O emissions. However, the mechanisms of reduction remain unclear. Here we demonstrate the significant impact of biochar on denitrification, with a consistent decrease i...

global air pollution is a serious threat caused by excessive use of fossil fuels for transportation. despite the fact that diesel fuel is a big environmental pollutant as it contains different hydrocarbons, sulphur and crude oil residues, it is yet regarded as a highly critical fuel due to its wide applications. nowadays, biodiesel as a renewable additive is blended with diesel fuel to achieve ...

Traditional model-based studies that evaluate air quality control measures predict how the health benefits of a prescribed reduction in emissions will be distributed across different locations—for instance, how reformulating gasoline will benefit people in New York versus those in Los Angeles. But traditional models cannot feasibly quantify the influence of individual emissions sources on human...

We present a framework for allocating a global carbon reduction target among nations, in which the concept of "common but differentiated responsibilities" refers to the emissions of individuals instead of nations. We use the income distribution of a country to estimate how its fossil fuel CO(2) emissions are distributed among its citizens, from which we build up a global CO(2) distribution. We ...

The prospect of state government driven carbon emission reduction targets brings with it the prospect of local target setting. Such targets will need to be based on good quality estimates of energy demand and greenhouse gas emissions along with viable assumptions about reduction potential at the local level. So there is a growing requirement for good quality emissions data at the level of local...

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...

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...
