Why Are Metrics Important?

In this video, Louise Summerton at the Green Chemistry Centre of Excellence, University of York explains why we need metrics to provide a mechanism to assess the greenness of a reaction.[1]

Choosing a Method Exercise

Looking at this PDF, here are a couple of questions to consider:

  • Which one would you choose as the greenest method?  
  • How much can we tell from yield alone?

We will revisit this example at the end of the module.
