Abstract

A method for haul road design based on greenhouse gas emissions comprises receiving a first set of performance data associated with a plurality of machines and establishing a greenhouse gas emission limit for the plurality of machines based on the first set of performance data. A target greenhouse gas emission level for each of the plurality of machines is determined based on the greenhouse gas emission limit, and total effective grade is determined based on the target greenhouse gas emission level for the respective machine. The method also includes generating a haul road design based on the total effective grade.
