‘Novel entities,’ are defined as, “things created and introduced into the environment by human beings that could have positive or negative disruptive effects on the Earth’s system.” One of the challenges for the GEF is deciding which new technologies offer solutions that can increase global environmental benefits while minimising potential adverse impacts, how these technologies relate to its mission, in what time frame, and what strategies will capture the most benefits. This STAP paper identifies new and upcoming technological advances relevant to GEF’s work and proposes an approach to addressing them.
