Obtaining information on cleaner production can be a challenging task of sifting through the seemingly endless amount of resources that are constantly changing. Not only is new information being made available every day, but the terminology used to describe cleaner production and preventive environmental activities is evolving. Terms such as pollution prevention, waste minimization, green productivity, source reduction, eco-efficiency and clean technologies are also used to refer to the Cleaner Production concept. Hence, searching available information can be a lengthy process. This is why, as part of its Cleaner Production Programme, UNEP IE has decided to publish this booklet, which presents a number of information sources that can be of assistance in obtaining further information about cleaner production.
