Short summary

Seventy percent of global CO₂ emissions were emitted from urban landscapes. The Yangtze River delta (YRD) ranks as one of the most densely populated regions in the world and is an anthropogenic CO₂ hotspot. Besides anthropogenic factors, natural ecosystems and croplands act as significant CO₂ sinks and sources. Independent quantification of the fossil and cement CO₂ emission and assessment of their impact on atmospheric δ¹³C-CO₂ have potential to improve our understanding of urban CO₂ cycling.
