`tramp-remote-process-environment' is meant to *set* environment
variables on the remote host. There is no Tramp function which *reads*
them. The following code snippet might help you:

(let ((default-directory "/ssh:remotehost:"))
  (with-output-to-string
    (shell-command "set" standard-output)))

The Tramp FAQ explains several approaches, how to shorten remote file
names. See
