Using a broad range of materials (media and interviews), we analyse the development of three green megaprojects in the two northernmost regions of Sweden. We find support for the presence of a strong ideological fantasy tied to a few “green heroes”, supporting the notion that the investments are the ultimate answer not only to climate crisis but also to the territory’s perceived left-behindness. The symbolic construction of the fantasy also contributes to the production of killjoys through marginalizing and feminizing opposition to the megaprojects. Our analysis thereby points to the importance of a feminist intervention and critique of the neoliberal ideology that frames green megaprojects.
