It estimated that by 2030 there will be over 25 billion active Internet of Things devices worldwide, while the zettabytes of data being generated through our interactions with so-called ‘smart’ technologies is increasingly contributing to ICT’s overall carbon footprint which now accounts for around 4% of global CO2 emissions. Although emerging technologies can help us to make better sense of the world and offer important breakthroughs for many sectors like healthcare, transport and manufacturing, our rapid embracement Internet of Things, Artificial Intelligence and related innovations is also leading to the depletion of precious natural resources, rising carbon emissions and mountains of obsolete technology. To explore these challenges, this talk will present a series of design research projects that apply novel design futuring methods including Design Fiction and Experiential Futures to illustrate how the environmental impacts arising through the greater adoption of ‘smart’ data-driven technologies can be made more visible, engaging and potentially actionable to publics, policy makers and industry.
