Are green cities sustainable? A degrowth critique of sustainable urban development in Copenhagen

This paper proposes a case-based degrowth critique of sustainable urban development strategies. Copenhagen, European Green Capital in 2014, is considered a role model of planning for sustainability. Does this hold in a degrowth perspective? Sustainable development assumes that environmental impacts can decline while the economy grows. Degrowth maintains that such a process of absolute decoupling is infeasible. Analyzing Copenhagen's planning documents in this perspective, I find three factors that make the city's sustainability strategy ineffective for ecological sustainability. First, Copenhagen's strategy for climate neutrality is based on externalization: only emissions produced locally are counted. Meanwhile, emissions produced outside of the city for products and services consumed locally remain high. Secondly, policies focus on the efficiency of activities rather than their overall impact: efficiency gains are considered reductions of impact, but really mean slower growth of impact. Finally, sustainability measures are proposed as a 'green fix', to increase competitiveness and promote economic growth, leading to increased consumption and impact. Analyzing the critical case of Copenhagen in a degrowth perspective, sheds doubts on sustainable urban development, but does not imply the rejection of all its typical planning measures. This induces reflections on how these results can contribute to a degrowth-oriented urban planning.
