In the 1990s the rates of increase of greenhouse gas concentrations, most notably of methane, were observed to change, for reasons that have yet to be fully determined. This period included the eruption of Mt. Pinatubo and an El Niño warm event, both of which affect biogeochemical processes, by changes in temperature, precipitation and radiation. We examine the impact of these changes in climat...

Purpose – The purpose of this paper is to investigate empirically how information and communication technologies (ICT) can contribute to reduction of CO2 emissions in road freight transport and to identify opportunities for further improvements. Design/methodology/approach – This research adopts a multiple case study approach with three leading UK grocery retailers as exemplars of fast-moving c...

On the basis of nine periodical measurements, emissions of PCDD/F have been analysed. As a result, a correlation was detected between elevated PCDD/F emissions and operational problems with selective catalytic reduction (SCR) system. The air pollution control system (APCS) consisted of dry scrubbing system (mixture of active carbon and NaHCO3), fabric filter, DeNOx catalyst and wet scrubber. It...

Rising obesity rates may contribute to greenhouse gas emissions both directly through increased food production and indirectly through higher passenger weights and increasingly sedentary lifestyles. Using panel data for the fifty US states over the period 1997 to 2011 we examine the relationship between the obesity rate and carbon dioxide emissions from energy use. Results indicate a positive a...

Heterogeneous small-cell networks (HetSNets) are considered as a standard part of the future mobile networks in which multiple low-power, low-cost user deployed base stations complement the existing macrocell infrastructure. This paper proposes an energy efficient deployment of the small-cells where the small-cell base stations are arranged around the edge of the reference macrocell and the dep...

SUMMARY In the Northern Territory, savanna fires are the major single source of greenhouse gas emissions. A privately-funded project involving strategic fire management has shown that it is possible to mitigate emissions from fire, with social, economic and other environmental benefits. This case study discusses the implications of having savanna fire abatement projects recognised as offsets wi...

In the climate change world, the policy process has concluded that cost-effective approaches for the reduction of greenhouse gases can provide a useful incentive to the developed world to reduce their emissions. One approach for cost-effective emission reduction is the Clean Development Mechanism established under the Kyoto Protocol (KP 1997, Art. 12). The Clean Development Mechanism (CDM) allo...

Carbon emissions research based on regional perspective is necessary and helpful for China to achieve its reduction targets. This research aims at analyzing the energy-related carbon emissions and finding out the most important driving forces for the carbon emissions increments in Guangdong province. LMDI (Logarithmic Mean Divisia Index) method based on the extended Kaya identity has been used ...

Studies of how carbon reduction policies would affect agricultural production have found that there is a connection between carbon emissions and irrigation. Using county level data we develop an optimization model that accounts for the gross carbon emitted during the production process to evaluate how carbon reducing policies applied to agriculture would affect the choices of what to plant and ...
