The Global Resource Information Database (GRID) is a worldwide network of environmental data centres created by UNEP in the mid-1980s. GRID-Centres are made of a team of data scientists who on top of their technical expertise also fully understand the UNEP mandates, thus helping to bring the most relevant data and information. The main functions of a GRID-Centre are to acquire data, transforming them into information and knowledge about the state of the world’s environment in a timely and understandable manner, before disseminating these to support environmental governance and policies.
