INTRODUCTION Korea has been making efforts to reduce greenhouse gas (GHG) emissions, including a voluntary commitment to the target of a 30% reduction, based on business-as-usual of the total GHG emission volume, by 2020; 2006 IPCC Guidelines provided default values, applying country-specific emission factors was recommended when estimating national greenhouse gas emissions. RESULTS AND DISCU...
In most countries, environmental regulation has focused on local pollution, which causes damages near the emission source, while national regulation on greenhouse gases (GHG) has been slow. In this paper, we ask whether US local air pollution regulations have had an effect on GHG emissions. On the one hand, a firm required to lower emissions of local pollutants might respond by adopting technol...
Trading of greenhouse gas (GHG) emission reductions is an attractive approach to help producers implement cleaner treatment technologies to replace current anaerobic lagoons. Our objectives were to estimate greenhouse gas (GHG) emission reductions from implementation of aerobic technology in USA swine farms. Emission reductions were calculated using the approved United Nations framework convent...
Demand for tools to rapidly assess greenhouse gas impacts from policy and technological change in the agricultural sector has catalyzed the development of 'GHG calculators'- simple accounting approaches that use a mix of emission factors and empirical models to calculate GHG emissions with minimal input data. GHG calculators, however, rely on models calibrated from measurements conducted overwh...
Information and Communication Technologies (ICT) are expected to have a great potential to reduce the GHG emissions across society, however limited data on actual reductions have been published so far. Based on available data on real GHG emission reductions realized by different ICT solutions, this paper explores the possible reductions globally within a 2030 timeframe. An average of the future...
Limited information is available on the perceptions of stakeholders concerning the health co-benefits of greenhouse gas (GHG) emission reductions. The purpose of this study was to investigate the perceptions of urban residents on the health co-benefits involving GHG abatement and related influencing factors in three cities in China. Beijing, Ningbo and Guangzhou were selected for this survey. P...
To facilitate the efforts to identify greenhouse gas (GHG) and criteria air pollutants (CAP, representing CO, VOC, NOx, SOx, PM10 and PM2.5) emission-reduction opportunities that may be specific to particular regions, this paper intends to estimate regional differences in life-cycle GHG and CAP emissions from light-duty vehicles in the US, using the GREET (the Greenhouse gases, Regulated Emissi...
Accounting of greenhouse gas (GHG) emissions from waste landfilling is summarized with the focus on processes and technical data for a number of different landfilling technologies: open dump (which was included as the worst-case-scenario), conventional landfills with flares and with energy recovery, and landfills receiving low-organic-carbon waste. The results showed that direct emissions of GH...
The goal of this review was to analyze published data on animal management practices that mitigate enteric methane (CH4) and nitrous oxide (N2O) emissions from animal operations. Increasing animal productivity can be a very effective strategy for reducing greenhouse gas (GHG) emissions per unit of livestock product. Improving the genetic potential of animals through planned cross-breeding or se...
Due to the large-scale utilization of high-carbon fossil energy, considerable amounts of critical air pollutants (CAPs) and greenhouse gas (GHG) have been emitted, which has led to increasingly serious global climate change and local air pollution problems. Given that climate change and air pollution have the same source, energy systems, the rational development and use of energy for collaborat...
