The work of activist Greta Thunberg, the rise of the Extinction Rebellion movement and this summer’s damning report by the IPCC, warning of a “code red for humanity”, have combined to put the challenges of the climate crisis firmly into consumer consciousness.

Fashion, in particular, has been put under the microscope as one of retail’s biggest contributors to carbon emissions.
