From two billion tons to zero: taking on our big waste problem through the circular economy

Stage 6 (Upper level)
19/06/2024, 16:30 - 18:00

Cities produce just over 2 billion tons of solid waste each year and by 2050, this figure is expected to rise to close to 4 billion tons. While cities are a strong driver for waste generation, they also offer opportunities to implement zero-waste and circular economy strategies and practices where they can matter most.

This session introduces the concept of zero-waste and explores how cities can achieve this outcome by utilizing a circular economy approach. With global attention increasingly focused on waste issues, how can local and regional governments benefit from international processes such as the UN’s International Zero-Waste Day and the UN Secretary General’s Advisory Board, both of which ICLEI is a part of. Attendees will also get an inside look at the GIZ project Circular City Labs, which promotes reusable packaging solutions in cities.
