Excavators are one of the most energy-intensive elements of earthwork operations. Predicting the energy consumption and CO2 emissions of excavators is therefore critical in order to mitigate the environmental impact of earthwork operations. However, there is a lack of method for estimating such energy consumption and CO2 emissions, especially during the early planning stages of these activities...

The CO 2 emissions were measured in environmental rooms in 15 animal operation studies, including studies of dairy cow, steer, swine, turkey, laying hen and broiler. The objectives of this paper are to summarize CO 2 emission data in these 15 studies;, to investigate the possible diet effect; and to evaluate the performance of the CO 2 balance approach to estimate ventilation rate (VR) of anima...

In the era of globalization and international trade, the production-based CO2 emissions accounting system, proposed by United Nations Framework Convention on Climate Change, can easily lead to a “carbon leakage” issue. Thus, the accounting of consumption-based carbon emissions and carbon emissions embodied in international trade has received considerable research attention. Nevertheless, resear...

Stump harvesting for energy has decreased in Finland, and many heat power plants no longer accept stumps their fuel portfolio due to quality problems. However Finland is a forested country, land clearing need be extracted, e.g. infrastructure construction projects. If cannot used production, they are dumped landfills, where start decay release CO2 into the atmosphere. One option avoid emissions...

During August–September 2012, we sampled six hydropower reservoirs in southeastern United States for CO2 and CH4 emissions via three pathways: diffusive emissions from water surface; ebullition in the water column; and losses from dam tailwaters during power generation. Estimates of average areal emission rates of CO2 attributable to the six reservoirs (i.e., reservoir plus tailwater emissions)...

In this paper, the p-median model is used to find the location of retail stores that minimizes CO2 emissions from consumer travel. The optimal location is then compared with the existing retail location, and the excess CO2 emissions compared with the optimal solution is calculated. The results show that by using the environmentally optimal location, CO2 emissions from consumer travel could be r...

In the past 50 years, higher education institutions worldwide have progressively implemented sustainability policies focused on improving their environmental indicators and institutional image. This trend also occurs in Colombia, both private public institutions. One of issues associated with that has experienced increasing interest by these entities is Climate Change, which reflected an number...

Forests mitigate climate change by absorbing CO2. However, N2O emissions in forests, which has 298 times larger global warming potential than CO2, can diminish the mitigation role of forests. Thus, it is crucial to project not only CO2 absorption but also forests provide a scientific basis for 1.5 °C Paris Agreement goal. This study used biogeochemical model, called FBD-CAN, and South Korean fr...

the increase of greenhouse gases (ghg) in which co2 emissions constitute the principal component, is of major environmental problems of all societies. economic growth impels intensive use of resources and as a result, more residues and wastes thrown in the nature that could lead to environmental degradation. this article tries to trace the eventual relationship between trade openness and enviro...

The demand for fossil fuel in the transport sector is constantly increasing and transportation is ranked amongst the highest greenhouse emitting sectors globally. Today, tackling CO2 emissions from road transport a widely discussed topic and constitutes a milestone towards reaching a sustainable, carbon neutral economy. This challenge is being described in various initiatives adopted in the ...
