According to the 2009 Greening of Corporate America Report, over half (58%) of the C-level executives surveyed believe corporate sustainability practices are either unaffected or aided by the economic crisis.
The Report states, "This result is consistent with a number of studies that suggest the downturn is a time to innovate. During such times of less activitiy, firms have an opportunity to align resources and create new strategy in order to reposition themselves to gain advantage when the economy recovers. Further, as sustainability becomes entrenched in common corporate practices, these efforts that lead to cost-savings will be of particular importance during downturns."
