We investigated the millennial variability (1000 A.D.-2000 A.D.) of global biogenic volatile organic compound (BVOC) emissions by using two independent numerical models: The Model of Emissions of Gases and Aerosols from Nature (MEGAN), for isoprene, monoterpene, and sesquiterpene, and Lund-Potsdam-Jena-General Ecosystem Simulator (LPJ-GUESS), for isoprene and monoterpenes. We found the millenni...

In the metropolitan area of São Paulo, Brazil, ozone and particulate matter (PM) are the air pollutants that pose the greatest threat to air quality, since the PM and the ozone precursors (nitrogen oxides and volatile organic compounds) are the main source of air pollution from vehicular emissions. Vehicular emissions can be measured inside road tunnels, and those measurements can provide infor...

Urban spatial expansion affects almost every dimension of sustainable urban development. A good grasp the relationship between evolution and carbon emissions can be key to governance. As a central city in region national low-carbon pilot city, Changsha has experienced rapid construction land growing emissions. In this paper, four variable factors five emission were used for case 1979, 1996, 200...

unlike other studies in which the autours have focused on testing the existence of an environmental kuznets curve, in this study, causality relationship between the energy consumption (oil equivalent), carbon emissions, gross domestic production, total labor force and fixed capital formation is investigated during 1960 to 2007 in iran. following an examination of stationary tests for all the va...

the market for carbon dioxide rights emerged as one of the tools applicable to the implementation of the measures adopted by the kyoto protocol to combat climate change. in this paper we analyze the case of spain, because their peculiar administrative division into seventeen autonomous communities, it is relevant to a detailed study of emissions and allowances of the industries that make up ...

Carbon emissions from energy consumption of Shandong province from 1995 to 2012 are calculated. Three zero-residual decomposition models (LMDI, MRCI and Shapley value models) are introduced for decomposing carbon emissions. Based on the results, Kendall coordination coefficient method is employed for testing their compatibility, and an optimal weighted combination decomposition model is constru...

Country by country emission inventories for carbonaceous aerosol for the period 1860 to 1997 have been constructed on the basis of historic fuel production, use and trade data sets published by the United Nation’s Statistical Division UNSTAT (1997), Etemad et al. (1991) and Mitchell (1992, 1993, 1995). The inventories use emission factors variable over time, which have been determined according...

We used a biogeochemistry model, the Terrestrial Ecosystem Model (TEM), to study the net methane (CH4) fluxes between Alaskan ecosystems and the atmosphere. We estimated that the current net emissions of CH4 (emissions minus consumption) from Alaskan soils are approximately 3 Tg CH4/yr. Wet tundra ecosystems are responsible for 75% of the region's net emissions, while dry tundra and upland bore...
