Perhaps you should try some spelling variations:
"global environment governance series." » "global environmental governance series.", "global evironmental governance series.", "global environment government series.", "global environment governance system."
"global environmental performance system." » "global environmental performance states.", "global environmental performance sse3.", "global environmental performance instead."

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"global environment governance series.\") OR (\"global environmental performance system.\"))".
• Removing quotes may allow a broader search: (( global environment governance series. ) OR ( global environmental performance system. )).
• Adding a wildcard symbol may retrieve word variants: (("global environment governance series.") OR ("global environmental performance system."))*.
