In this video, Louise Summerton at the Green Chemistry Centre of Excellence, University of York describes a variety of other parameters, aside from efficiency based metrics, that should be taken into consideration when assessing the greenness of a reaction.
In this exercise, (attached here) we revisit the direct amidation example looked at earlier and examine some of the wider considerations to assess the greenness of the reaction (Scheme 1). You will need to use the data sheet to complete the exercise.
