... and global energy and carbon emission trends that could have been used in conjunction with the Kaya identity to quantitatively analyze recent trends in energy and carbon emissions in North America (e.g., EIA, 2017; Feng et al., 2015; Shahiduzzaman and Layton, 2015; Vinuya et al., 2010)

... . Scenarios that attempt to meet national goals also provide useful information about mitigation potentials and the roles of energy efficiency, low carbon energy sources, prices and behavior in managing carbon flows from the energy system.

... P110, Line 152 The treatment of mitigation is unsatisfying for several reasons: - impacts, past and potential future, of management actions are not quantified; - the critical role of increased energy efficiency in all sectors is given inadequate attention, especially since there have been and are important initiatives in place in North America; - the challenge of transforming the energy system to a low carbon system (energy transition) is also not adequately discussed and analyzed; - none of the projections of future energy use come close to achieving climate stabilization goals, a critical issue for the future of the energy system.

... P119, Line 7 "As demonstrated,…" is arguable and unneeded. P119, Line 11-20 Why does this section not mention technologies identified by the EPA/DOT rulemaking for increasing light-duty vehicle fuel economy through 2025, and medium and heavy-duty fuel economy as well.

... P138, Line 12 – P140, Line 18 None of the scenarios discussed correspond to a serious attempt to reduce GHG emissions to levels that would stabilize global warming at target levels proposed by climate scientists (e.g., 2°C, 2.5°C, etc.)

... we know for certain that fugitive emissions reduce the overall carbon benefits. Considering the report recognizes that biofuels vary in their carbon impacts, we suggest rephrasing this finding or present it in a different way.
