There is a proposal in the TODO list (see tramp.el):

;; * Implement a general server-local-variable mechanism, as there are
;;   probably other variables that need different values for different
;;   servers too.  The user could then configure a variable (such as
;;   tramp-server-local-variable-alist) to define any such variables
;;   that they need to, which would then be let bound as appropriate
;;   in tramp functions.  (Jason Rumney)

process-environment would be one of the candidates.
