Urban expansion / infrastructure development Forestry & Land Use Your challenge: developing sector strategies to achieve net zero. Your problem challenge is to work individually and collaboratively to develop and present ideas that will best enable the achievement of net zero emissions across a value chain of your choice. The transition to net zero is a complex systems challenge, requiring more radical action and a shift in focus from individual organisations to value chains and sectors across what will be a whole-of economy universal transformation. ● My team will address the overarching sector of ‘Forestry & Land use’ to identify the multiple scope of emissions contributing to a global increase in co 2 emissions Forestry and Land Use sector distribution Camille Lefevre Monoculture (Land Use) Dev Trivedi Mining (Land Use) James Sadeik Wood Logging (Forestry) Tasnia Ahmad Urban Development (Land Use) Zac Braden Ranching (Land Use) How does increasing Urban Development contribute to collective emissions? 1. Increased energy consumption: Urbanisation increases energy consumption, which can contribute to an increase in carbon emissions. Urban inhabitants consume more energy than rural counterparts. However, given the predicted population boom to 9.8 billion people by 2050 1 - urbanisation is necessary, however it must be remodelled in a way that reduces global warming and co2 emissions. Cities are the primary source of glasshouse gas emissions and an important arena for reducing carbon emissions. Urbanisation creates market demand pushing pressures for economic expansion, which is accompanied by increased energy consumption and carbon emissions. The major drivers of energy consumption and carbon emissions are urbanisation and industrial restructuring in urban growth. 2. Changes in land use: Urbanisation can result in the loss or fragmentation of plant cover and vegetation, resulting in carbon emissions from land use conversion. 1 https://www.un.org/en/desa/world-population-projected-reach-98-billion-2050-and-112-billion-2100

Emissions Type Scope Definition Examples Direct Urban Development construction organisations and City Planners / Governments who hire these companies Scope 1 Emissions from operations that are owned or controlled by the reporting company The increase of urban thermal heat contributing to increased global warming in Australia and Asia 1) The emission of building companies and more in transporting materials to doze land and create buildings 2) Cutting away natural vegetation to make room for new cities and buildings ● https://www.smh.com. au/national/nsw/bliste ring-temperatures- dark-roofing-banned- on-sydney-s-urban- fringe-20210820- p58kma.html? fbclid=IwAR0RGc2Rc Ul7lZQpOLQA1nODg qocfGtxMFUruL13Md jWxQim3HPA1xNEBl E Dark Roofing in Sydney from Australian developers to create living space for our growing population will cause a ‘heat island’ effect Potential solutions ● backyards which are big enough to plant a tree or have a garden ● Reducing dark roofs that create heat island ● Which further reduces need to electricity usage and constant air conditioning

China’s Urban Heat Island https://www.frontiersin.org/art icles/10.3389/feart.2020.0034 0/full#:~:text=Over%20east %20China%2C%20UHI %20effects,warming%2C %20respectively%20 (Yang %20et%20al Over east China, UHI effects contributed 24.2% to regional average warming trends, and the strongest effect of urbanization on annual mean surface air temperature trends occurred over the metropolis and large city stations, with corresponding contributions of about 44% and 35% to total warming, respectively (Yang et al., 2011). In addition, the rapid increase of the urban population leads to a large amount of anthropologic heat release, which caused a significant rise in high temperature in the urban center and a strong UHI. Indirect Scope 2 Emissions from the generation of purchased or acquired electricity, steam, heating, or cooling consumed by the reporting company ● Usage of electricity over 19 hours a day to reduce heat temperatures ● Where electricity is the great emitter of co2, directly remodelling to sustainable development ventures can assist in reducing co2 emissions and meet the targets of the SGD’s Scope 3 All indirect emissions ● As urbanisation also
