Consumption-based screening of climate change footprints for cities worldwide

With long-term prospects indicating worldwide increasing urbanization over the next decades, cities are responsible for a growing share of global greenhouse gas emissions. This makes local policies more important in mitigating climate change, and calls efficient tools allowing decision makers to measure impact urban areas under their control. study introduces parsimonious screening tool cater this need allow governments gauge monitor consumption-based change footprint cities. The consists multiple-regression models that operate on easily accessible city data. To demonstrate its applicability, per capita is estimated 949 Australian found have highest per-capita footprint, averaging 20.4 t CO2-eq, while South American lowest 8.1 CO2-eq. results evaluated against IPCC mitigation pathways judge which track an absolute sustainable level Few be comply with necessary levels 2030, findings thus substantiate all planet major actions required mitigation.
