To do so, it focuses on the case of "social practice theory" (SPT), a school of thought which has gained prominence in human geography and further afield in recent years. The paper outlines the context of environmental policy literatures and identifies a tension in many treatments of the topic by practice-oriented scholars: while it focuses on emergent social change, the traditional policy imaginary which has circulated in this literature often portrays benign, top-down policy makers who, given adequate information, are amenable to conducting the right policy "intervention." A "governance on the inside" approach is proposed as an alternative imaginary, drawing from prominent work on polycentric governance and community economies in geographical and economic scholarship, as well as more recent work in SPT itself. Opportunities for a geographical mapping of policy difference and reflexive engagement are highlighted, hinting at rich future possibilities.diverse economies, governance, participation, policy, polycentrism, social practice theory 1 | INTRODUCTION This paper examines the performative implications of scholarly imaginaries around policynamely, who is conceived as a policy maker and how policy-driven social change is deemed to occurexploring how current perspectives in this area can obscure, promote, or hold back exploration of environmental governance alternatives. It constitutes a provocation to think seriously about policy relevance and policy makers, given the sometimes under-specified usage of such terms among researchers searching for policy "impact." Social Practice Theory (SPT), which examines how the rise of particular configurations of practices result in (un)sustainable societies, provides a case study for how social scientists conceive of policy and environmental interventions. The relevance of SPT stems from both its recent prominence and expansion in the social sciences, andmore importantlythe critical stance of SPT scholarship towards hegemonic concepts in environmental policy-making. While immediate generalisation from SPT to the wider environmental transitions literature and beyond is not appropriate, there are certainly lessons to be gleaned from it.The paper proceeds as follows. Section 2 outlines the context for environmental policy amid a narrowing of policy questions in a neoliberal milieu. In this section, a useful (albeit imperfect) distinction emerges between "policy" and "government," on the one hand, and "governance," on the other. Rather than repeat the theoretical foundations of SPT at length (see instead Everts et al., 2011), section 3 more closely examines paradigmatic treatments of policy in SPT scholarship. A tension is noted, whereby, contrary to the focus of SPT on emergent social change, the predominant circulating imaginary ---
