Perhaps you should try some spelling variations:
"global environment performance series." » "global environmental performance series.", "global environmental performances series.", "global government performance series.", "global environment performance metrics.", "global environment performance reviews.", "global environment performance targets."
"global environment performance review." » "global environmental performance review.", "global environmental performances review.", "global government performance review.", "global environment performance risk.", "global environment performance evidence."

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (("global environment performance series.") OR ("global environment performance review."))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"global environment performance series.\") OR (\"global environment performance review.\"))".
• Removing quotes may allow a broader search: (( global environment performance series. ) OR ( global environment performance review. )).
• Adding a wildcard symbol may retrieve word variants: (("global environment performance series.") OR ("global environment performance review."))*.
