The importance of jointly considering environmental issues such as Biodiversity Conservation and Climate Change has been increasingly emphasised. According to the last IPCC report (2014, p. 24) “Increasing efforts to mitigate and adapt to climate change imply an increasing complexity of interactions, particularly at the intersections among water, energy, land use, and biodiversity, but tools to understand and manage these interactions remain limited”. This paper intends to explore the conflicts arising from the internalisation of the regulatory regimes of Biodiversity and Climate Change in Brazil. Through the lens of Cultural Theory, the paper develops an analysis of the processes of standard-setting, information-gathering and behaviour modification in each of these two regulatory regimes. It intends, therefore, to shed light on the reasons behind important conflicts and of the absence of coordination between both policy areas in Brazil.
