The digitalisation of society, work, and the economy profoundly impacts the future course of human prosperity and ecological sustainability. Though dominant imaginaries privilege digital technologies for achieving sustainable development, future jobs, and economic progress, rapid digitalisation comes with hidden environmental and social costs. The ICT ecosystem, for example, has been estimated to account for more than two per cent of global carbon emissions. Even though the world is increasingly digitally dependent, more than half of the world’s population is still offline or unable to reap the benefits. Ultimately, transitions towards just and sustainable digital societies will depend on how we develop, and deploy these technologies through creative, participatory and just means.
