Perhaps you should try some spelling variations:
carbon transport » urban transport
transport later » transport water, transport master, transport rates
idea transport » ideas transport, sea transport, de transport
later across » water across, labor across, letters across
new carbon » low carbon, de carbon, key carbon
vague one » vague de, vase one
case new » use new
one idea » one sided, new idea, one side

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

• If you are trying to use Boolean operators, they must be ALL CAPS: (( case new carbon transport later across ) OR ( vague one idea transport demand model ))~.
• Adding a wildcard symbol may retrieve word variants: (( case new carbon transport later across ) or ( vague one idea transport demand model ))*.
