Global Warming Potential (GWP) significance of HCFC refrigerant gases
The global warming potential of chemicals is well documented. This is usually documented by referencing how much a chemical will impact global warming as compared to a similar amount of carbon dioxide. Refrigerants typically outrank carbon dioxide by a factor of 100 or even 1000 and stay in the atmosphere longer to our climate's detriment. All greenhouse gases are allocated a global warming ...

Food waste – global warming potentials of the options
Food waste (FW) is a problem and an opportunity. This paper will review the alternativen routes for its management. In the UK, the majority of FW is still landfilled. Traditionally, FW has been fed to pigs but part of the reaction to the 2001 outbreak of foot and mouth disease in the UK was to ban this “swill feeding” and introduce stringent requirements for treating FW that later was the basis ...

Global Warming Potential, CO2 Equivalence and the Impacts of Fossil Fuel Combustion
A greenhouse gas (GHG), as defined by the Intergovernmental Panel on Climate Change (IPCC) is a compound which has the ability to trap heat over a certain lifetime in the atmosphere. The six main GHG gases are carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), hydrofluorocarbons (HFCs), perfluorocarbons (PFCs) and sulphur hexafluoride (SF6). The impact of these GHG gases is quantified ...

The Cost of Using Global Warming Potentials: Analysing the Trade off Between CO2, CH4 and N2O
Abstract The metric governing the trade-off between different greenhouse gases in the Kyoto Protocol, the Global Warming Potentials (GWPs), has received ample critique from both scientific and economic points of view. Here we use an integrated climate-economic optimization model to estimate the cost-effective trade-off between CO2, CH4 and N2O when meeting a temperature stabilization target. We ...

Greenhouse gas emissions and global warming potential of reclaimed forest and grassland soils
Received for publication June 19, 2008. Although greenhouse gas (GHG) emissions from soils are important, reclaimed mine soil (RMS) ecosystems are not widely assessed. Postreclamation land uses (forest, hay, and pasture) were investigated to: (i) monitor the magnitude of GHG fluxes, (ii) estimate their global warming potential (GWP), (iii) identify the relationship between GHG fluxes and soil ...

Global environmental impacts of the hydrogen economy
Hydrogen-based energy systems appear to be an attractive proposition in providing a future replacement for the current fossil-fuel based energy systems. Hydrogen is an important, though little studied, trace component of the atmosphere. It is present at the mixing ratio of about 510 ppb currently and has important man-made and natural sources. Because hydrogen reacts with tropospheric hydroxyl ...

The use of methanotrophic applications to control of fugitive methane emissions from the biodegradation of organic waste
Large amounts of methane (CH4) escapes to the atmosphere through fugitive emissions arising from anthropogenic sources. This is detrimental because the Global Warming Potential (GWP) of CH4 is 25 times that of carbon dioxide (CO2) on a 100 year time horizon. As a result, there has been increasing interest in developing cost–effective and reliable alternatives for the minimisation of CH4 releases ...

Sewage sludge as fertiliser – environmental assessment of storage and land application options
Sewage sludge (SS) contains beneficial plant nutrients and organic matter, and therefore application of SS on agricultural land helps close nutrient loops. However, spreading operations are restricted to certain seasons and hence the SS needs to be stored. Storage and land application of SS are both potential sources of greenhouse gases and ammonia, leading to global warming, acidification ...
