The UK government’s recent Climate Change Bill set an ambitious target of an 80% reduction in emissions by 2050. This level of response to climate change has profound implications for individual choices and behaviour, as well as for the social structures in which these operate. With over one third of many nations’ carbon emissions coming from private travel and domestic energy use, individuals ...
With the emergence of the response to climate change as a global agenda, UNFCCC member countries must report their Greenhouse Gas (GHG) emissions and absorptions. With conventional carbon emission estimation methods such as the IPCC Guideline, however, it is impossible to measure reduction of carbon emissions by U-City services. Therefore, this study proposed estimating carbon emission reductio...
BACKGROUND Reducing carbon Emissions from Deforestation and Degradation (REDD+) is of central importance to combat climate change. Foremost among the challenges is quantifying nation's carbon emissions from deforestation and degradation, which requires information on forest carbon storage. Here we estimated carbon storage in India's forest biomass for the years 2003, 2005 and 2007 and the net f...
For urban economies, an ecological endowment embodiment analysis has to be supported by endowment intensities at both the international and domestic scales to reflect the international and domestic imports of increasing importance. A three-scale input–output modeling for an urban economy to give nine categories of embodiment fluxes is presented in this paper by a case study on the carbon dioxid...
A growing body of literature discusses the CO2 emissions of cities. Still, little is known about emission patterns across density gradients from remote rural places to highly urbanized areas, the drivers behind those emission patterns and the global emissions triggered by consumption in human settlements—referred to here as the carbon footprint. In this letter we use a hybrid method for estimat...
This paper provides an empirical analysis of the long-run market shares of four ENERGY STAR (ES) appliances in the United States: refrigerators, dishwashers, clothes washers, and room air conditioners. We relate state-level market shares to electricity prices, demographics, and energy efficiency. We then use the results to estimate how a carbon pricing mechanism might influence the market share...
during the recent decades, rapid urbanization growth has led to even faster growth of motorvehicles and especially in large cities. hence, evaluation of the actual level of traffic emissions has gained more interest. this paper, for the first time, presents a bottom-up approach for evaluation of vehicular emissions in tehran- the capital of iran- using the international vehicle emission (ive) m...
Carbon transfer via international trade affects the spatial pattern of global carbon emissions by redistributing emissions related to production of goods and services. It has potential impacts on attribution of the responsibility of various countries for climate change and formulation of carbon-reduction policies. However, the effect of carbon transfer on climate change has not been quantified....
Industrial agricultural plantations are a rapidly increasing yet largely unmeasured source of tropical land cover change. Here, we evaluate impacts of oil palm plantation development on land cover, carbon flux, and agrarian community lands in West Kalimantan, Indonesian Borneo. With a spatially explicit land change/carbon bookkeeping model, parameterized using high-resolution satellite time ser...
The decoupling of fossil-fueled electricity production from atmospheric carbon dioxide emissions via CO2 capture and sequestration (CCS) is increasingly regarded as an important means of mitigating climate change at a reasonable cost. Engineering analyses of CO2 mitigation typically compare the cost of electricity for a base generation technology to that from a similar plant with CO2 capture an...
