China has become the world’s largest carbon emitter. Its total carbon emission output from fossil fuel combustion and cement production was approximately 10 Gt CO2 in 2013. However, less is known about carbon emissions from the production of industrial materials, such as mineral products (e.g., lime, soda ash, asphalt roofing), chemical products (e.g., ammonia, nitric acid) and metal products (...

We use a standard computable general equilibrium model to explore the fiscal implications of stringent carbon dioxide emission reduction in Europe. Both the immediate targets (2030% by 2020) and the medium-term targets (80-90% by 2050) for abatement can be met with a carbon tax that is modest to sizeable. Imposing budget neutrality, a carbon tax that would allow all other taxes to fall by 5% (2...

Economic development usually leads to increased energy consumption, which in turn will result in an increase in carbon emissions. To break the relationship between economic development and carbon emissions, scholars have turned their attention to the phenomenon of decoupling. In this paper, we studied the decoupling relationship between carbon emissions and economic growth of the equipment manu...

It is believed that the primary economic solution to climate change is an introduction of a carbon pricing system anchored to the social cost of carbon, either as a form of tax or tradable permits. Potentially significant externalities accompanying the introduction of emission-reducing technologies, however, imply that the standard argument does not capture some important aspects for the design...

The purpose of this work is to present elements of a design tool for field emission displays using carbon nanotubes as emitters. We use a continuum model to describe the carbon nanotubes and we use a locally one-dimensional approximation to calculate the emission current. We investigate the emission current to voltage characteristic, screening effects and the lateral spread of the emission curr...

This paper analyses trading and banking of carbon emission rights. Within the framework of a modestly simple, integrated assessment model that brakes the world economy in just two regions, North and South, it can be shown: (1) There exists separability between environmental targets and the choice of instruments. Increasing the "when and where" flexibility in greenhouse gas abatement either thro...

Concern about climate change has evoked interest in the potential for urban vegetation to help reduce the levels of atmospheric carbon. This study applied computer simulations to try to quantify the modifying effects of existing vegetation on the indirect reduction of atmospheric carbon for two residential neighborhoods in north-west Chicago. The effects of shading, evapotranspiration, and wind...

Single- and multiwalled carbon nanotubes have been covalently functionalized with free-base porphyrin. The quantity of porphyrin linked to the surface was determined from thermogravimetric and UV-vis analysis. A reversible protonation equilibrium between the attached porphyrin and the residual acid groups of the carbon nanotubes has been identified. Steady-state fluorescence emission spectrum o...

An innovated wastewater resourcing system (WRS) was formal proposed to couple the production of polyhydroxyalkanoates (PHAs) and electricity generation by microbial fuel cell (MFC) with the proper controlled acidification digester. This paper gave the carbon audit and cost analysis of WRS to estimate its carbon emission, energy saving and profit production. Results showed WRS extracts 18% of in...

We investigated the effect of helium and nitrogen pressures on the dynamics of molecular species formation during laser ablation of carbon. For producing plasmas, planar carbon targets were irradiated with 1064 nm, 6 ns pulses from an Nd:yttrium aluminum garnet laser. The emission from excited C2 and CN molecules was studied using space resolved optical time-of-flight emission spectroscopy and ...
