Biochar has been shown to reduce soil emissions of CO2, CH4 and N2O in short-term incubation and greenhouse experiments. Such controlled experiments failed to represent variable field conditions, and rarely included crop growth feedback. The objective of this study was to assess the effect of biochar, in comparison to green manure and mineral nitrogen, on greenhouse gas Emissions Intensity (EI ...

The Shenzhen ETS is the first urban-level “cap-and-trade” carbon emissions trading scheme to operate in China. This paper gives an overview of the economic and emissions situation in Shenzhen and focuses on the development of the Shenzhen ETS regulatory framework. It is devised as an ETS with an intensitybased cap, output-based allocation and a market for trading of allowances. The design of th...

Abstract: Reduction of NOX emissions and fuel consumption are the main topics in engine development, forcing the adoption of complex techniques and components, whose interactions have to be clearly understood for proper and reliable operations and management of the whole system. The investigation presented in this paper aimed at the development of integrated control strategies of turbocharging,...

Methanol is found throughout the troposphere, with average concentrations second only to methane among atmospheric hydrocarbons. Proposed global methanol budgets are highly uncertain, but all agree that at least 60% of the total source arises from the terrestrial biosphere and primary emissions from plants. However, the magnitude of these emissions is also highly uncertain, and the environmenta...

A bottom-up inventory of atmospheric emissions of industrial MNVOCs in Yangtze River Delta (YRD) region was established for the period of 2010–2012. Results indicated that the total emissions of industrial VOCs increased from 3.34 Tg in 2010 to 3.99 Tg in 2012 at an annual average rate of 9.3%. Furniture manufacturing, machinery equipment manufacturing, architectural ornament, and petroleum ref...

introduction sarcheshmeh copper mine is regarded as the second largest copper deposit in the world. this is one of the largest industrial-mining complexes in the world and the largest producer of copper in iran. this complex plays an important role in iran’s economy. in 2012, this complex created employment for about 8000 people in iran and produced 203065 tons of copper cathodes. however, high...

Reducing emissions is essential for minimizing the impact of soil fumigation on the environment. Water application to the soil surface (or water seal) has been demonstrated to reduce 1,3-dichloropropene (1,3-D) emissions in soil column tests. This study determined the effectiveness of water application to reduce emissions of 1,3-D and chloropicrin (CP) in comparison to other surface seals under...

Temporal index decomposition analysis and spatial index decomposition analysis were applied to understand the driving forces of the emissions embodied in China's exports and net exports during 2002-2011, respectively. The accumulated emissions embodied in exports accounted for approximately 30% of the total emissions in China; although the contribution of the sectoral total emissions intensity ...

The challenges posed by global climate change are motivating the investigation of strategies that can reduce the life cycle greenhouse gas (GHG) emissions of products and processes. While new construction materials and technologies have received significant attention, there has been a limited emphasis on understanding how construction processes can be best managed to control GHG emissions. Unex...

In this paper a model-based traffic control is used to design variable speed limits and onramp metering rates in order to reduce road traffic generated area-wide emissions near freeways. First an area-wide emission model is proposed and next a nonlinear model predictive control (MPC) approach is applied. The objectives of the MPC controller considered are the emissions, dispersions of emissions...
