Since 2010, grassroots-led socio-ecological movements in Québec, Canada played a key role in overturning carbon extractivist proposals. Building on their successes, these groups now aim to move energy transition debates toward a broader conception of transition that includes radical social justice and post-capitalist alternatives. Meanwhile, corporate actors and the state enlisted major ENGOs and union federations into various technocentric “green growth” projects. These hegemonic and counter-hegemonic struggles define how transition unfolds in the province, yet few have studied how actual social actors organize to carry out these divergent responses to the climate crisis. We develop a structural analysis of the green growth policy-planning network in Québec. Starting from five organizations at the core of transition debates, we analyze the network of board interlocks they are embedded in. We describe the overall structure of the network and its main corporate, civil society, and individual actors. Analysis outlines the possibility of a new power bloc forming, positioned around the green growth project and the cleantech sector, close to achieving dominance in Quebec, that would threaten deeper decarbonization efforts. Thus, despite the recent ban on petroleum extraction, like elsewhere, energy transition in Quebec still faces deep social and ecological contradictions.
