Through a recent modeling experiment, a team of NASA-funded researchers have found that future concentrations of carbon dioxide and ozone in the atmosphere and of nitrogen in the soil are likely to have an important but overlooked effect on the cycling of water from sky to land to waterways.

Here, RME show advantages for primary energy and GHG, but disadvantages in terms of acidification, eutrophication and ozone depletion. There is an obvious link between environmental impacts estimated by life-cycle impact assessments and water quality problems described at the regional scale. Source: “Assessing Biofuels”.

A few studies also include other relevant impact indicators as acidification potential, eutrophication potential, ozone depletion potential and various toxicity potentials. However very few studies include water use impacts. In their paper on the impact of ethanol production on nutrient cycles and water quality, Simpson et al.
