Waste disposal in the current situation, which quantity and variety of waste are increasing, needs not only effective management principles but also depends on environmentally-friendly methods to put as less environmental footprint as possible. This study aims to assess the energy consumption, emission of greenhouse gases and air pollutants which normally produce during various waste management...
The present study, in addition to investigating the impacts of GDP and gasoil consumption as the biggest consumed petroleum product in Iranian transportation sector, by introducing petroleum product intensity, studied their effects on CO2 emission in this sector. To evaluate the impact of the variables, we estimated an autoregressive distributed lag (ARDL) model between the years 1996 and 201...
Abstract This research has aimed to examine the feedback effects between economic growth and environmental degradation through health that is one of human capital elements and also the consequences of such these relationships on economic convergence process during the period 1990-2013 for 60 developing countries in framework of simultaneous equations model by using unbalanced panel data analysi...
An increasingly common type of environmental policy instrument limits the carbon intensity of transportation and electricity markets. In order to extend the policy’s scope beyond point-of-use emissions, regulators assign each competing fuel an emission intensity rating for use in calculating compliance. I show that welfare-maximizing ratings do not generally coincide with the best estimates of ...
Nowadays, environmental protection has become the most public issue in the world. Thanks for the Kyoto Protocol that has established a trading system for greenhouse gas emissions worldwide; China has more chances to take part in environmental protection by carbon trading. But in recent years, carbon trading has been growing amazingly in China in volume but not in quality, which signs that it is...
We investigate the rapid formation and evolutionary mechanisms of an extremely severe and persistent haze episode that occurred in northern China during winter 2015 using comprehensive ground and vertical measurements, along with receptor and dispersion model analysis. Our results indicate that the life cycle of a severe winter haze episode typically consists of four stages: (1) rapid formation...

Research News raditionally, U.S. environmental policy has emphasized mandatory regulations that prescribe limits on emissions of pollutants or the use of specific abatement technology such as scrubbers. While these regulations have protected the environment, they have encouraged firms to concentrate on pollution controls that operate at the end of the factory smokestack or at the point of efflu...
This paper reviews information from the existing literature and the EU GMOS (Global Mercury Observation System) project to assess the current scientific knowledge on global mercury releases into the atmosphere, on global atmospheric transport and deposition, and on the linkage between environmental contamination and potential impacts on human health. The review concludes that assessment of glob...
