a r t i c l e i n f o It is generally understood that greenhouse gasses produced by human activities are having a warming effect on the climate. Discussions concerning efforts to curb carbon dioxide emissions often focus on large countries. However, considerable resources have been spent to reduce carbon dioxide emissions by relatively small, open economies. Although, these economies are small ...
Development of regional policies to reduce net emissions of carbon dioxide (CO2) would benefit from the quantification of the major components of the region's carbon balance--fossil fuel CO2 emissions and net fluxes between land ecosystems and the atmosphere. Through spatially detailed inventories of fossil fuel CO2 emissions and a terrestrial biogeochemistry model, we produce the first estimat...
The project deals with collecting data on greenhouse gas emissions on the Caltech campus. The emissions are categorized in 3 scopes. Scope 1 includes direct emissions, scope 2 indirect emissions from purchased water and electricity and scope 3 other indirect emissions. The data is used as an input in a Carbon footprint calculator, giving as an output a corresponding number of tons of carbon dio...
In this paper, a collaborative power dispatching system (CPDS) was developed to maximize the profit of a regional biomass power system consisting of an independent power grid. A power generating, dispatching and carbon emissions trading system (CETS) could be engaged in joint strategic planning and operational execution. The principal of CPDS is interactive planning of generating units in power...
UNLABELLED A natural gas burner has been used as a precise and accurate source for generating large quantities of carbon dioxide (CO2) to evaluate emissions measurements at near-industrial scale. Two methods for determining carbon dioxide emissions from stationary sources are considered here: predicting emissions based on fuel consumption measurements-predicted emissions measurements, and direc...
There are a number of state and utility policies that reduce total carbon emissions, while shifting emissions from other sectors to power plants. The most significant are policies to expand the use of electric vehicles (EVs) 1 . Increased deployment of EVs will increase electricity consumption and thus will generally increase carbon emissions by utilities but in most states will reduce total ca...
The pulp and paper industry, which is closely related to national economic and social development, is an important industry but also contributes high carbon emissions. Therefore, with the advent of the low-carbon economic era, ways to reduce the carbon emissions and to bring about a low-carbon industrial transition of the pulp and paper industry is becoming one of the important academic project...
Xinjiang's agricultural carbon emissions showed three stages of change, i.e., continued to rise, declined and continued to rise, during 1991-2014. The agriculture belonged to the "low emissions and high efficiency" agriculture category, with a lower agricultural carbon emission intensity. By using the logarithmic mean divisia index decomposition method, agricultural carbon emissions were decomp...
United States (US) is currently responsible for about 20% of global carbon emissions. The residential sector is responsible for a little over 20% of this emission. From this perspective, US households account for about 4% of global carbon emissions. Such sector-based approach is commonly used in energy analysis and energy policy. However, this is not necessarily a complete representation of the...
This paper investigates the development trends and variation characteristics of China’s economy, energy consumption and carbon emissions from 2007 to 2030, and the impacts on China’s economic growth, energy consumption, and carbon emissions under the carbon tax policy scenarios, based on the dynamic computable general equilibrium (CGE) model. The results show that during the simulation period, ...
