Jason Hickel and I have exchanged a few rounds of public debate, prompted by his critique of ”green growth” published at Fast Company. The question being debated is whether decoupling offers a pathway towards a sustainable future. His core conclusion is that the answer is no, and that ecomodernists such as myself are indulging in magical thinking. “Even under best-case scenario conditions,” Hickel argued, “absolute decoupling of GDP growth from material use is not possible on a global scale,” and certainly is not enough to reduce material use sufficiently to stay within planetary boundaries. Consequently, he argued that slowing GDP growth is necessary to avoid environmental collapse.
