In this paper we analyze the driving factors of CO2 emissions in the context of environmental regulations using a dynamic panel data model for the period 1960 to 2009. Given the current policy debate and the importance of evaluating the effectiveness in terms of emission reductions of the already established climate agreements, we investigate to what extent emission reduction obligations from t...

Isoprene emissions importantly protect plants from heat stress, but the emissions become inhibited by instantaneous increase of [CO2], and it is currently unclear how isoprene-emitting plants cope with future more frequent and severe heat episodes under high [CO2]. Hybrid aspen (Populus tremula x Populus tremuloides) saplings grown under ambient [CO2] of 380 μmol mol(-1) and elevated [CO2] of 7...

The Homogeneous Charge Compression Ignition is an alternative combustion technology that can reduce automobile pollution, provided that the exhaust emission can be controlled. A parametric study can be useful in order to gain more understanding in the emission reduction possibilities via this new combustion technology. For this purpose, the inlet temperature, the equivalence ratio and the compr...

Reducing carbon dioxide (CO2) emissions has become a global consensus in response to global warming and climate change, especially to China, the largest CO2 emitter in the world. Most studies have focused on CO2 emissions from the production sector, however, the household sector plays an important role in the total energy-related CO2 emissions. This study formulates an integrated model based on...

Introduction of closed cycle gas turbines with their capability of retaining combustion generated CO2 can offer a valuable contribution to the Kyoto goal and to future power generation. Therefore research and development work at Graz University of Technology since the nineties has led to the Graz Cycle, a zero emission power cycle of highest efficiency. It burns fossil fuels with pure oxygen wh...

All these gases are addressed by the Revised 1996 IPCC Guidelines for National Greenhouse Gas Inventories (IPCC Guidelines). The technical approach in estimating CO2 emissions is relatively simple and the accuracy level high since the CO2 emission factors are mainly a function of the fuel properties, which are generally well addressed by most countries. The non-CO2 emissions however are closely...

Introduction of closed cycle gas turbines with their capability of retaining combustion generated CO2 can offer a valuable contribution to the Kyoto goal and to future power generation. Therefore research and development at Graz University of Technology since the 90's has lead to the Graz Cycle, a zero emission power cycle of highest efficiency. It burns fossil fuels with pure oxygen which enab...

One of the most considerable issues in the global society is reducing CO2 emissions of industrial activities and its consequences. Therefore, exploitation of clean energy sources is one of the requirements of the international community. In this regard, the researchers investigated the impact of renewable energy utilization to achieve the low carbon economy and concluded that it can significant...

Tianjin is the largest coastal city in northern China with rapid economic development and urbanization. Energy-related CO2 emissions from Tianjin’s production and household sectors during 1995–2012 were calculated according to the default carbon-emission coefficients provided by the Intergovernmental Panel on Climate Change. We decomposed the changes in CO2 emissions resulting from 12 causal fa...
