We need to rapidly draw down carbon from the atmosphere, and radically reduce the amount we are pumping out at the same time. If that were achievable, what might the world look like? What would our lives be like in 2040? To explore this, we welcome back Seona Candy, research fellow with the Victorian Eco-innovation Lab at the University of Melbourne. VEIL and Seona are a part of the Australian Cooperative Research Centre for Low Carbon Living (CRCLCL) and their Visions and Pathways 2040 (VP2040) project. VP2040 is a research and engagement project to develop, analyse and communicate visions and pathways for transforming Australian cities to achieve rapid decarbonisation and increased resilience in the face of climate change. And their latest and final report -- the result of their multidisciplinary four year study just came out. It explore two very different scenarios for achieving a low carbon world.
