Why environmental impact assessments often fail

Abstract

The environmental impact assessment (EIA) is a nearly universal instrument intended to limit or to offset the environmental tolls of development projects. Here, I describe some of the key shortcomings of EIAs in terms of their real-world application, especially in developing nations that harbor much of the world’s imperiled biodiversity. A surprisingly large number of EIAs suffer from major inaccuracies and some are green-lighting projects that will have serious environmental and societal costs. I summarize by proposing eight strategies to help improve the conservation capacities of EIAs.
