• Research challenges
• System Vs. System boundaries
• Example Finnish forest industry imports and
  exports
• System Vs. System component
• Example Inter vs. Intra-organizational
  management
• Eco-efficiency Vs. Growth
• Example The rebound effect and the Jevons
  paradox, e.g. fuel efficient cars vs. mileage
  driven
• Downstream impacts Vs. Upstream root causes
• Example CFCs, SO2 as known impacts
• Waste Vs. Its definition (cultural/social
  construct)
• Examples Past vs. present, Developed vs.
  Developing countries
