Abstract:

The authors modeled the CO₂ emissions reductions expected from Australia’s fleet under three standard designs, one standard curve for all LDVs (“One-curve”), two standard curves that align with Europe’s existing approach (“Two curves–PC/LCV”), and two standard curves that align with the U.S. approach (“Two curves–SUV split”). SUVs are “split” in the United States in that they can fall under either the PC or LCV category, depending on certain attributes. Results show that the One-curve approach would yield fewer cumulative CO₂ emissions from Australia’s LDV fleet from 2019 to 2050 than the other approaches.
