RESUMO
Sustainability certificates are increasingly used as tools for shaping bioeconomic production processes and trade. However, their specific effects are subjected to debate. A multitude of certificate schemes and standards are currently in use, defining and measuring sustainability in the bioeconomy in highly varying ways. Different representations of environmental effects, resulting from the use of different standards or scientific methods in certification, can have very real implications for how, where and to which degree bioeconomic production can be conducted and the environment will be conserved. Further, the implications for bioeconomic production practices and management embedded in the environmental knowledge employed in bioeconomic sustainability certificates will produce different winners and losers, and privilege some societal or individual concerns at the expense of others. In this way, sustainability certificates share some characteristics with other standards and policy tools that embody political contingencies, but are presented and often understood as objective and neutral. The paper argues that the politics of environmental knowledge involved in these processes warrant more awareness, scrutiny and explicit consideration from decision makers, policy developers and researchers.
