We are publishing the article by Catalina Picón, landscape architect, and co-founder of Fundación Cerros Isla, on the Cerros Isla restoration in Santiago, Chile. The platform behind it is built on environmental compensation — a regulatory requirement imposed on companies whose development projects generate excess PM10 emissions. Fundación Cerros Isla acts as a broker, channeling those obligations toward restoration sites — in this case, the degraded hills surrounding the city. While the ecological work the platform performs is real, it is worth saying: ecology cannot be offset. Restoration tied to a pollution debt is not the same as restoration as public commitment, or lowering environmental and social impact in the first place. The difference has consequences for who is responsible for these landscapes in the long run. The hills themselves — degraded, privately owned, worked over by extraction and neglect — are the kind of ground landscape architects encounter constantly. We share this article to hear your experience with similar instruments. What do they make possible, and at what cost.
