Abstract
This discussion paper seeks to contribute to the small but growing knowledge base on the linkages between the informal economy and the environment. On the one hand, it aims at increasing the understanding of how issues of informality and the environment are connected, articulating the various dimensions of these linkages. On the other hand, the paper seeks to reflect on how strategies to promote formalization can also support environmentally sustainable outcomes and vice versa. Case studies from the waste management, artisanal and small-scale mining, construction and agriculture sectors are presented to illustrate how linkages play out. The review and analysis draws out recommendations for further research as well as lessons for a possible integrated approach to address formalization and environmental sustainability.
