Note from the editor:

As green commentators speculate about the future of environmentalism in the wake of the COVID-19 crisis, it is more important than ever that green thinking should grow and evolve.

In issue 5, we explore new approaches to ideas about climate change. Some articles propose big green changes which might fit into a ‘post-corona’ portfolio of green proposals. Some reflect on the outcomes of existing green approaches, and others interrogate the purpose and ethics of new technologies that aim to improve the environment.
