Stated in another way, we want/need to sustain the resource base that provides the foundation upon which any society exists,
develops, and survives…

Which of these forms of Sustainability
must/should/could/would we use in Latin
America?
Fourth, the lack of a unified theoryof sustainability…
• Sustainability is currently expressed in multiple forms:– Frameworks– Models– Principles– Concepts– Heuristics– Strategies– Guidelines– Specifications– Standards– Processes/Tools– Best Practices– Lessons Learned…

...create triggers of change...
Triggers are changes in: • Values • Mission • Perceptions
FLASH
Triggers are changes of: • Functional Requirements • Physical Integrity /Function
CRASH
Triggers are changes caused by: • Market • Benchmarks • Competition
SPLASH
Triggers are changes in: • Codes • Regulations • Standards
CLASH
Regardless of the trigger, sustainability will inevitably force change, and how organizations respond will make them end…
either with a Pile of CASH… or as a Pile of ASH…
