Job: PhDs in Environmental Engineering

"Applying engineering principles and methods, geoengineers work towards clean air, water and soil for the human society, but also for all living organisms and fight to remedy the pollution, degradation and destruction of natural habitats. Geoengineering can be regarded as Environmental Engineering with a broader scope and action."

Project ongoing: Reviewing the potential impacts of geoengineering on ecosystems and biodiversity

Project by University of Cambridge and UNEP / WCMC. "Work on this review is ongoing, and it will provide a very useful reference guide for those seeking to research or respond to developments in geoengineering. It will also help people to access the latest information on twenty of the geoengineering techniques currently being discussed and their potential positive or negative impacts on biodiversity."
