Originally a wacko, hippy-esque ideology, ‘sustainability’ - aka ‘eco-friendly’ or ‘green’ - has now become globally accepted. But as what - an environmental urgency, a political issue, a technical problem, a historic destiny, a new world order? And what are the consequences of this acceptance? The sustainability consensus is dangerous since the concept has no political content and can be used for any cause. Carbon neutrality and zero emissions are like magic formulas, cover-ups for complicated ethical questions about the inequalities in our societies.Yet striving for zeros or hiding in neutrality does not lead to a better life in a more desirable house in a superior city for everyone.After Zero is not about design inspired by the fear of tsunamis or Katrinas. Volume proposes an understanding of our society beyond zero. To kick off we discuss two perspectives: sustainability in a post-capitalist city and the potential of urban agriculture.
