Abstract: In this article, I take issue with (eco-)socialists who embrace an ecological critique of growth under capitalism, but remain supportive or agnostic of the prospects for socialist growth. First, I argue that economic growth is ecologically unsustainable—whether it is capitalist or socialist does not make a difference. Second, I claim that economic growth rests to a large extent on exploitation. While it is logically possible to have non-exploitative socialist growth, in practice it is unlikely. Third, socialist policies are likely to have a negative effect on growth. A transition to socialism is a transition beyond growth.
