Emissions from ethanol transport in the CMU study applied to ethanol life cycle emissions from other studies. A new study by researchers at Carnegie Mellon University (CMU) concludes that the emissions associated with the transport of ethanol could negate its potential economic and environmental benefits compared to gasoline.

Recent work has shown that chemoselective hydrogenation of ring-strained monoterpenes is an effective strategy for the generation of high-performance fuels. Alternatively, the alkenes can be easily converted to cyclopropane rings, which further enhances the density and volumetric heat of combustion (NHOC) of these hydrocarbons.

Partly for these reasons, many LCA studies truncate impact assessment at the inventory characterization step, rather than completing normalization and weighting steps. Following normalization of the inventory and weighting, the SMA-LCIA model determines the rank acceptability index (RAI) of each fuel on a scale from 1 to 5.
