Radically new economic arrangements are needed for just and sustainable transitions to a more environmentally and ecologically resilient world. Yet little progress is being made to imagine the new economy‐environment relations around which resources, actors, and ethics might be configured to enact the novel economic forms needed. This article uses a Social Studies of Economisation and Marketisation (SSEM) approach to examine a suite of differently scaled and structured environmentally focused economic development initiatives in New Zealand. We explore how the initiatives have assembled diverse actors and investment projects into experimental economy‐environment relations. Our account highlights experimentation as a pivotal mode of economisation, and we argue that the initiatives studied by us expose a new experimentation‐led agenda for transitioning to more environmentally and economically just futures. Working with the idea of experimentation in an SSEM framework, we also argue that the diverse initiatives are creating an experimentation infrastructure that provides a more generative platform for novel economy‐environment relations than top–down models of change such as transition pathways. The article opens up a critical politics of environmental economy that focuses attention on emergence, agency, and practice and allows us to reimagine processes of transitioning.
