introduction carbon sequestration is one of the most important approaches to reduce co2 concentration in the atmosphere. increase of co2 in the atmosphere has prompted renewed interest in increasing the stocks of carbon (c) in the world’s croplands to mitigate climate change and also improve soil quality ipcc (2000). to better characterize, predict and manage soil c dynamics, more precise and a...

As the carbon trading scheme has a significant impact on China’s sustainable economy and environmental protection, policy influence of emissions emission efficiency in pilot provinces become key research topic. Based data 30 cities China from 2007 to 2018, this paper estimates by using super-efficiency SBM model, difference-in-difference method is adopted investigate policy’s influence. The res...

This paper analyzes and processes the time sequence of carbon emissions from the perspective of the BP neural network, revealing the structure and the law of all kinds of index systems of carbon emissions and describing the dynamic characteristics of carbon emissions system. Based on the synthesis of the energy structure factors, energy efficiency factors, economic development factors, populati...

Regional carbon dioxide emissions study is necessary for China to realize the emissions mitigation. An environmental input–output structural decomposition analysis (IO-SDA) has been conducted in order to uncover the driving forces for the increment in energy-related carbon dioxide emissions in Xinjiang from both production and final demands perspectives from 1997 to 2007. According to our resea...

The observation of electron emission from amorphous carbon thin films at low applied electric fields is explained in terms of an enhancement of the field brought about by dielectric inhomogeneities within the film. These inhomogeneities originate from the differences between conductive, spatially localized sp C clusters surrounded by a more insulating sp matrix. By a more complete understanding...

To meet the targets of the Kyoto Protocol, European Union has established the European Emission Trading Scheme, a mandatory market for carbon emission allowances. This regulatory framework has introduced a market for emission allowances and created a variety of emission-related financial instruments. In this work, we show that the economic mechanism of carbon allowance price formation can be fo...

This paper discusses the role of the Clean Development Mechanism (CDM) on the market for carbon quotas and countries’ commitments to reduce their carbon emission levels. We show that the CDM contributes to an efficient funding of clean technology investments in least developed countries. However, the CDM is not neutral on the global level of carbon emissions as it entices countries to raise the...

abstract the study examines the growth effects of foreign direct investment on environmental quality in nigeria between 1970 and 2013. variables like per capita income, environmental degradation, foreign direct investment, human capital, inflation, trade openness, interest rate, and the interaction term between foreign direct investment and carbon emission were employed in the study. a long run...

Plants undergoing heat and low-CO2 stresses emit large amounts of volatile isoprenoids compared with those in stress-free conditions. One hypothesis posits that the balance between reducing power availability and its use in carbon assimilation determines constitutive isoprenoid emission rates in plants and potentially even their maximum emission capacity under brief periods of stress. To test t...
