Many “business-as-usual” (BAU) scenarios have
explored the potential consequences of the world
continuing its dominant development model. Most recent
scenarios of this type are “dynamics-as-usual” (DAU)
scenarios that assume across the board incremental
improvements following past dynamics. In principle,
these scenarios are the closest to future projections.
They provide a sketch of what the world could look like
in 2050, if we continued the historical path of incremental
improvements in reaction to perceived crises, instead
of a shift toward a long-term perspective that aims to
anticipate the troubles ahead
