Implication

Randomized trial estimates CO2 emissions in cities, highlighting disparities and suggesting tailored mitigation strategies.

Key Points

  • This research aims to analyze and estimate carbon emissions at the city level, focusing on urban characteristics in the Yangtze River Delta region.
  • Developed a city-level carbon emissions accounting model using multi-source data for 41 cities (2013-2022)
  • Categorized cities into five types using the K-means algorithm
  • Employed a Geographically and Temporally Weighted Regression (GTWR) model to analyze emissions drivers.
  • Total carbon emissions in the Yangtze River Delta rose from 1,700 Mt in 2013 to approximately 1,931 Mt in 2022.
  • 14.6% of cities with emissions over 80 Mt contribute to 40.3% of total emissions.
  • Population, per capita GDP, industry structure, and energy intensity are identified as significant upward drivers of emissions.
