Minimizing the future impacts of climate change requires reducing the greenhouse gas (GHG) load in the atmosphere. Anthropogenic emissions include many types of GHG’s as well as particulates such as black carbon and sulfate aerosols, each of which has a different effect on the atmosphere, and a different atmospheric lifetime. Several recent studies have advocated for the importance of short tim...

Under economic globalization, with the intensification of China’s reform and opening up, China’s outward foreign direct investment (OFDI) has continuously gained momentum, but CO2 emissions caused by the OFDI have not been given due attention. As one China is of the world’s leading CO2 emitters, it is necessary to conduct thorough research into the CO2 emission problem caused by China’s OFDI. T...

global warming is one of the major concerns in environmental issues. its effects are being exposed faster than anticipated recently. it causes adverse ecological and socioeconomical effects. the 4th assessment report issued by the u. n.’s intergovernmental panel on climate change (ipcc) states that it is appropriate to define global warming was caused by greenhouse gases due to human activities...

The carbon emissions has attracts great concerns in engineering technology researches. The decomposition analysis technology has been popular in the study on influencing factors of industrial carbon emissions (ICE). The change of industries’s CO2 emissions from the three main industries in China over the period 1980-2011 based on the logarithmic mean divisia index (LMDI) method has been carried...

Direct emissions of air pollutants from the cement industry in China were estimated by developing a technology-based methodology using information on the proportion of cement produced from different types of kilns and the emission standards for the Chinese cement industry. Historical emissions of sulfur dioxide (SO2), nitrogen oxides (NOX), carbon monoxide (CO), particulate matter (PM) and carb...

co2 emissions from combustion flue gases have turned into a major factor in global warming. post-combustion carbon capture (pcc) from industrial utility flue gases by reactive absorption can substantially reduce the emissions of the greenhouse gas co2. to test a new solvent (ait600) for this purpose, a small pilot plant was used. this paper presents the results of studies on chemical methods of...

The agriculture sector is known to be the one of the major contributors to global greenhouse gas (GHG) emissions. At the same time, global climate changes have affected the agriculture sector. In order to strengthen the sustainable development of agriculture, it is important to promote environmentally friendly farming and simultaneously increase the economic value. To improve the productivity o...

Urban forest management and policies have been promoted as a tool to mitigate carbon dioxide (CO2) emissions. This study used existing CO2 reduction measures from subtropical Miami-Dade and Gainesville, USA and modeled carbon storage and sequestration by trees to analyze policies that use urban forests to offset carbon emissions. Field data were analyzed, modeled, and spatially analyzed to comp...

Methane (CH4) effluxes by paddy-culture rice (Oryza sativa L.) contribute about 16% of the total anthropogenic emissions. Since radiative forcing of CH4 at current atmospheric concentrations is 21 times greater on a per mole basis than that of carbon dioxide (CO2), it is imperative that the impact of global change on rice CH4 emissions be evaluated. Rice (cv. IR72) was planted in sunlit, closed...

The sediments of coastal wetlands contain large stores of carbon which are vulnerable to oxidation once disturbed, resulting in high levels of CO2 emissions that may be avoided if coastal ecosystems are conserved or restored. We used a simple model to estimate CO2 emissions from mangrove forests, seagrass beds, and tidal marshes based on known decomposition rates for organic matter in these eco...
