2. What is Sustainable Development?
Brundtland report (1987) – “Development that meets the needs of the present without compromising the ability of future generations to meet their own need.”
Intra- and inter-generational equity
Anthropocentric
Sustainability of what?
non-declining aggregate output or consumption,
non-declining utility,
non-declining aggregate resources (productive base),
non-increasing pollution, …
Weak vs. Strong Sustainability
We choose non-declining utility as the criterion for sustainable development
some call this Weak Sustainability, but we don’t agree 
this still misses the intra-generational component
