With the growing pace of tablets use and the large focus it is attracting especially in higher education, this paper looks at an important aspect of tablets; their carbon footprint. Studies have suggested that tablets have positive impact on the environment; especially since tablets use less energy than laptops or desktops. Recent manufacturers’ reports on the carbon footprint of tablets have r...

Low carbon footprint energy sources such as solar and wind power typically suffer from unpredictable or limited availability. By globally distributing a number of these renewable sources, these effects can largely be compensated for. We look at the feasibility of this approach for powering already distributed data centers in order to operate at a reduced total carbon footprint. From our study w...

ecological footprint analysis in agriculture is a new and evolving subject. the main purpose of the study was to assess environmental sustainability of conventional and conservation tillage systems using ecological footprint analysis in hamedan province. global hectares (gha) were used to measure the ecological footprint unit. data was collected through questionnaires and use of cross-sectional...

The issue of carbon emissions has been on the corporate sustainability agenda for some years. For those working in agricultural supply chains the challenges remain significant, given the diverse direct and indirect emissions occurring throughout the value chain. This study determines the carbon footprint of the supply chain of Costa Rican coffee exported to Europe, using best practice methodolo...

 All electricity generation technologies emit greenhouse gases at some point in their life cycle and hence have a carbon footprint.  Fossil-fuelled generation has a high carbon footprint, with most emissions produced during plant operation. “Carbon capture and storage” could reduce these significantly, though this is unproven at full scale.  Nuclear and renewable generation generally have a ...

Global warming is accelerating and the world urgently needs a shift to clean and renewable energy. Hydropower is currently the largest renewable source of electricity, but its contribution to climate change mitigation is not yet fully understood. Hydroelectric reservoirs are a source of biogenic greenhouse gases and in individual cases can reach the same emission rates as thermal power plants. ...

Several brand owners are calculating the carbon footprint of sample products and intend to make the information available to their consumers as a label on the product. A physical label on the items or on the retail shelf will not be flexible enough to show the carbon footprint because of the dynamic nature of carbon emissions and the potential difference in footprint between instances of the sa...

The project deals with collecting data on greenhouse gas emissions on the Caltech campus. The emissions are categorized in 3 scopes. Scope 1 includes direct emissions, scope 2 indirect emissions from purchased water and electricity and scope 3 other indirect emissions. The data is used as an input in a Carbon footprint calculator, giving as an output a corresponding number of tons of carbon dio...

In recent years, the greenhouse effect has made a heavy global climate change and has seriously affect human survival and development environment. The global warming problem has become the focus of world attention. In order to meet requirements of environmental quality for global customers, the related activities within the life cycle for a product must be clearly defined in order to improve th...

Progressive cities worldwide have demonstrated political leadership by initiating meaningful strategies and actions to tackle climate change. However, the lack of knowledge concerning embodied greenhouse gas (GHG) emissions of cities has hampered effective mitigation. We analyse trans-boundary GHG emission transfers between five Australian cities and their trading partners, with embodied emissi...
