Hmmm... I may have misunderstood the point that the OP was trying to make. It sounded like the OP was saying that the Plugin Hybrid EV generated more GreenHouse Gasses (GHGs) than a conventional ICE vehicle. However, that wasn't what I got out of the linked article. Instead, the linked article seemed to be saying that PHEVs would only marginally reduce the life cycle GreenHouse Gasses (GHGs) when compared to non-Plugin HEVs.
Quote:
When charging PHEVs with electricity that has a GHG intensity equal to or greater than our current system, our results indicate that PHEVs would considerably reduce gasoline consumption but only marginally reduce life cycle GHGs, when compared to gasoline–electric hybrids or other fuel-efficient engine technologies. With a low-carbon electricity system, however, plug-in hybrids could substantially reduce GHGs as well as oil dependence.
...With the slow rate of capital turnover in the electricity sector, a low-carbon system may require many years to materialize. Considerable reductions in greenhouse gas emissions using plug-in hybrids in the coming decades will likely require decisions within the next ten years to develop a robust low-carbon electricity supply.

That seems to make sense... the PHEV is not going to have a
significant impact on GHGs compared to HEVs unless the source of electricity is low carbon.
Summary of the findings in graphical form below. Interesting to see how much E85 improves GHGs on a conventional ICE.
