Biodiversity offsets and payments for environmental services: Clarifying the family ties


Published on

Biodiversity Offsets (BO) and Payments for Environmental Services (PES) are sometimes used interchangeably to characterise innovative economic tools to conserve or restore biodiversity, ecosystems, or their services. The authors assume that a confusion between PES and BO can have negative implications for biodiversity conservation. In this paper, they argue that these two tools follow different targets and have different founding principles, and thus, their basic mode of functioning would only coincide under special circumstances and institutional contexts. Here, the researchers propose a new definition of BO, delimiting them more clearly from PES, and use practical examples to underscore conceptual differences.

Both tools require specific policy framework conditions, in terms of rights, responsibilities, and enforcement. If unmet, however, the implications for biodiversity conservation outcomes are stronger for BO than for PES since BO are explicitly linked to biodiversity losses, while PES typically are not. PES experiences can certainly inform BO implementation vis-à-vis contract design and enforcement, but these PES lessons need to be enacted vis-à-vis BO specific requirements, in order not to underestimate generic risks in their implementation: if a PES scheme fails, payments can be stopped; if a BO fails, biodiversity losses remain.
