Issues on climate change have been recognized as serious challenges for regional sustainable development both at a global and local level. Given the background that most of the artificial carbon emissions are resulted from the energy consumption sector and the energy is also the key element resource for economic development, this paper investigated the relationship between CO2 emission, fossil ...

an increase in energy prices will decrease the fossil fuel consumption; on the other hand, the cost-push will encourage technology improvement for firms and households. these changes will affect the emission level.this paper studies the changes of yearly pollutant emissions after an energy price reform in iran. we apply a computable general equilibrium model which consists of 7 energy goods (el...

This chapter addresses a topical issue: the creation of a global market for carbon dioxide (CO2) emission permits.1 The recent adoption in the Kyoto Protocol of an ambitious target for global CO2 emission has focused attention on policy instruments for achieving this goal. In addition, increasing awareness of the economic burden of environmental protection has produced an interest in market-bas...

The exchange of gaseous NH3 between the atmosphere and plants plays a pivotal role in controlling the global NH3 cycle. Photorespiration generates NH3 through oxygenation instead of carboxylation by the CO2-fixing enzyme, ribulose-1,5-bisphosphate carboxylase/oxygenase (RuBisCO). The future increase in the atmospheric CO2 concentration, [CO2], is expected to reduce plant NH3 production by suppr...

agriculture (mechanization), food industry and environment are the concepts that cannot be surveyed separately (because of their interaction). present research aimed to study tomato paste production by applying life cycle assessment. two functional unit of kg co2-eq/ kg tomato and kg co2-eq / kg paste was used. data were collected from one paste factory in alborz province and open-field tomato ...

The global carbon cycle is subject to intense research, where sources and sinks for greenhouse gases, carbon dioxide in particular, are estimated for various systems and biomes. Lakes have previously been neglected in carbon balance estimations, but have recently been recognized to be significant net sources of CO2. This thesis estimates emission of carbon dioxide (CO2) from boreal lakes and fa...

Forest harvest residues are important raw materials for bioenergy in regions practicing forestry. Removing these residues from a harvest site reduces the carbon stock of the forest compared with conventional stem-only harvest because less litter in left on the site. The indirect carbon dioxide (CO2) emission from producing bioenergy occur when carbon in the logging residues is emitted into the ...

Today, most countries are facing national CO2 targets focused on production and direct energy use. However, two important driving forces are increased consumption and changing consumption patterns. In this paper we analyse the impact from household consumption on CO2 emissions. Household energy use is taken into account, as is the consumption of commodities and services produced by industry. Ba...

This study evaluates the regional and sectoral CO2 emissions estimated by different CO2 emissions accounting methodologies around 2050 under different CO2 reduction scenarios. The production-based measurement of CO2 emissions is based on polluter pays principle, while the consumption-based measurement is based on beneficiary pays principle. In the field of global warming, the widely used method...

Direct quantification of fossil fuel CO2 (CO2ff) in atmospheric samples can be used to examine several carbon cycle and air quality questions. We collected in situ CO2, CO, and CH4 measurements and flask samples in the boundary layer and free troposphere over Sacramento, California, USA, during two aircraft flights over and downwind of this urban area during spring of 2009. The flask samples we...
