Sustainable development is like managing a finacial portfolio.
A portfolio manager has a set of financial assets which he manages to produce both current income and future value. To manage effectively, a portfolio manager needs information on both the value of the assets and their current yields. In effect, we collectively serve as Trustees of an Endowment which we manage both to meet our current needs and to assure future opportunities. At a minimum, to manage for sustainable development, we need information on the value or condition of the assets and resources in our Endowment and on its Current Output. Endowments are the economic, environmental and social resources, assets, and conditions that we inherit from previous generations and pass along to future generations.
