objective: the aims of this study were to determine energy efficiency and co2 use pattern of grape production in zanjan province, iran by a non-parametric method of data envelopment analysis (dea). methods: initial data were collected using a face to face questionnaire from 42 orchards in abhar city of zanjan province which is one of the most important centers of grape production in iran. the d...

Understanding the drivers of changes in CO2 emissions is vital for a range of stakeholders. Hence, this paper explores the main drivers of CO2 emissions in China using structural decomposition analysis based on constant price and non-comparative input-output tables. The driving forces at both nationwide and industrial levels are divided into nine effects. To investigate the effects from an ener...

Policy-makers have been sharing growing concerns that climate change has significant impacts on human society and economic activates. Knowledge of the influencing factors of CO2 emission is the crucial step to reduce it. In this paper, both CO2 emission and CO2 sink on a city-level of the nine cities in Wuhan Metropolitan Area are calculated using the Intergovernmental Panel on Climate Change a...

BACKGROUND Architectural methods that take into account global environmental conservation generally concentrate on mitigating the heat load of buildings. Here, we evaluate the reduction of carbon dioxide (CO2) emissions that can be achieved by improving heating, ventilating, and air conditioning (HVAC) technologies. RESULTS The Climate Change Research Hall (CCRH) of the National Institute for...

D. Burchart-Korol, M.Kruczek, Central Mining Institute, Katowice, Poland M. Pichlak, Silesian Technical University, Gliwice, Poland The main goal of the study was to present the most significant technological innovations aiming at reduction of greenhouse gas emission in steel production. Reduction of greenhouse gas and dust pollution is a very important aspect in the iron and steel industry. Ne...

CO2 emission influences not only global climate change but also international economic and political situations. Thus, reducing the emission of CO2, a major greenhouse gas, has become a major issue in China and around the world as regards preserving the environmental ecology. Energy consumption from coal, oil, and natural gas is primarily responsible for the production of greenhouse gases and a...

4 Emission inequality across countries and the contribution of the energy mix and the sectoral 5 composition of a country’s energy use are of central importance to the climate debate. We 6 analyze the evolution of inequality in global CO2 per capita emissions using both historical 7 data on energy-related CO2 emissions and future emission scenarios generated with the 8 integrated assessment mod...

A general energy structure system dynamics model is constructed applying the systematic dynamics theories and techniques.This mode is applied to predict the demand of energy and CO2 emissions by applying the situation analysis. The results reveal that a 58% reduction was found in the carbon intensity compared with the 2005 level, and we will realize the CO2 emission-reduction target in the bett...

In recent years, emissions from the road transportation industry in China have been increasing rapidly. To evaluate the reduction potential of greenhouse gas and pollutant emissions of the industry in China, its emission inventory was calculated and scenario analysis was created for the period between 2012 and 2030 in this paper. Based on the Long-range Energy Alternatives Planning System (LEAP...

Stronger than steel or titanium -and just as tough -metallic glasses are ideal materials for everything from cell-phone cases to aircraft parts. Replacing crystalline metals in the core of transformers, they can reduce significantly the energy losses. Typically, core loss can be 70%-80% less than with traditional crystalline materials, reducing the generation requirement, and when using electri...
