US is not planning to withdraw from the agreement, however it noted that a phasing implementation of the regulation will build experience both for the shipping industry and the energy sector.

An implementation in stages will be a measure to mitigate high fuel cost increases which will affect consumers, and could ensure that it will not be harmful to the global economy as well.
