CO2 emissions from maritime transport operations represent a substantial part of the total greenhouse gas emission. Vessels are designed with better energy efficiency. Minimizing CO2 emission in maritime operations plays an important role in supply chain decarbonisation. This paper reviews the initiatives on slow steaming operations towards the reduction of carbon emission. It investigates the ...

Jurisdictions across the globe are implementing CO2 emissions reduction policies. These policies typically ignore most locational issues, probably because the consequences of greenhouse gas emissions do not depend on the exact emission location. However, the response to emission policies and the costs and effectiveness of emissions reduction in power systems are locational in nature. This paper...

As argued by ‘Declaration of Concrete Environment (2010)’ of Korea and ‘Declaration of Asian Concrete Environment (2011)’ of six Asian countries, concrete as a single material has lately shown extremely large impact on environmental issues such as climate change. Assessment of environmental impact from concrete material and production has considerable importance. Concrete is a major material us...

As the main source of CO2 emissions in China, the industrial sector has faced pressure for reducing emissions. To achieve the target of 50% reduction of industrial carbon intensity by 2020 based on the 2005 level, it is urgent to formulate specific CO2 emission mitigation strategies in the provincial industrial sector. In order to provide decision-making support for the development and implemen...

We characterize the evolution of U.S. carbon dioxide (CO2) emissions using an index number decomposition technique which partitions the 1963-2008 growth of states’ energy-related CO2 into changes in five driving factors: the emission intensity of energy use, the energy intensity of economic activity, the composition of states’ output, per capita income and population. Compositional change and d...

The technological advancements in smart phones and their applications have rapidly raised the number of users and their data demands. To fulfil enlarged user’s data requirements, Basestation (BS) engages their resources over prolong time intervals at the cost of increased power consumption. In parallel, operators are expanding network infrastructure by employing additional BSs which also adds i...

Whereas various kinds of efforts have been paid to reduce greenhouse gas from manufacturing sector, emission has been significantly increased in non-manufacturing sector such as transportation, residential, commercial and service sector. Such GHG increase is closely related with urban activity both in direct way and in indirect way. The contribution of this non-manufacturing sector to all CO2 e...

With the increasingly severe global warming, investments in clean technology, reforestation and political action have been studied to reduce CO2 emission. In this study, a nonlinear stochastic model is proposed to describe the dynamics of CO2 emission with control inputs: clean technology, reforestation and carbon tax, under stochastic uncertainties. For the efficient resources management, a ro...

The soil CO2 emission is recognized as one of the largest fluxes in the global carbon cycle. Small errors in its estimation can result in large uncertainties and have important consequences for climate model predictions. Monte Carlo approach is efficient for estimating and reducing spatial scale sampling errors. However, that has not been used in soil CO2 emission studies. Here, soil respiratio...
