"The USA NDC commitment itself is not yet consistent with limiting warming to below 2°C, let alone with the Paris Agreement’s stronger 1.5°C limit"

"Even if all modelled policies are implemented, additional GHG reduction is probably required; we discuss several potential policies."

 USA's ranks higher in GHG reduction than Canada's but we are a) the snowiest land in the world, the second coldest and c) with low population density we are beset by nearly 3X the transportation distance/CO2 burden for any goods and services as for  the USA.  US  has  fully included managed forest land as a CO2 sink we have only in part.  Once complete this  is likely to provide credits of 72 MtCO2e  hence increases  GHG emissions allowed in 2030 under this target by about 12% of 1990 GHG emissions.
