Sustainable Neighborhoods: Emissions Inventary Framework

Based on the premise of reducing greenhouse gases (GHGs), many studies have been motivated to develop mitigation strategies for the impact of climate change through emissions accounting in the built environment. However, over the years, user behavior in choosing modes of transportation for daily activities has significantly contributed to the environmental impacts on global warming and human health. The objective is to analyze and evaluate the environmental impacts of urban mobility through motorized and electric transport in relation to the introduction of active mobility in the built environment, at the neighborhood scale, as a key mitigation strategy. The methodology uses consolidated data from the Intergovernmental Panel on Climate Change (IPCC, 2014), the International Energy Agency (IEA, 2023), life cycle assessment (LCA) studies, and the Ecoinvent v. 3.8 database. The Life Cycle Impact Assessment (LCIA) method ReCiPe, implemented in SimaPro software and adapted to the Brazilian context, is applied to develop an emissions inventory that quantifies and qualifies the following environmental impacts and indicators: (1) Global Warming (CO₂-eq) and (2) Human Health (NOx-eq, PM2.5-eq, and SO₂-eq).
