Good Evening;

I am studying for my LEED Green Associate exam and numerous practice exams are mixing me up per this question as they all give different answers. Can somebody please help me? Here is the question ...

Question 1-A): From worst to best (where 4 is the worst and 1 is the best), rank these following refrigerants (CFC, HFC, HCFC, Natural) in accordance with their GWP ? (ie: which has the worst GWP, it is a 4. Second worst, it gets a 3, etc...)

Question 1-B): From worst to best (where 4 is the worst and 1 is the best), rank these following refrigerants (CFC, HFC, HCFC, Natural) in accordance with their ODP ?

Thank You
