Abstract

Cities cover only ~3% of the world's surface yet originate 70% to 80% of global CO2 emissions and are expected to continue growing as urban migration continues and intensifies. Cities are projected to shelter ~70% of world's population by 2050. Managing urban emissions is vital to address the climate crisis and meet the objectives established by the United Nations Framework Convention on Climate Change and the Paris Agreement. To achieve this, we need to not only quantify and monitor emissions[4], but most importantly, attribute them to specific sources. Here we propose to improve and test the São Paulo greenhouse gas network to reach the necessary confidence level to combine and compare inventories and allow to track sources in specific regions using the combination of pollutants tracers and isotopes as radiocarbon. Furthermore, we want to explore the already generated greenhouse gas database to understand specific valuable periods such as the 2020 quarantine.
