Abstract

During the 14th Five-Year Plan period, the transition to low-carbon development in urban and rural construction has increasingly focused on achieving scalable low-carbon development and piloting near-zero carbon emission projects at the meso-scales and micro-scales. High-density urban districts in city centers serve as ideal settings for implementing near-zero carbon emission demonstration projects. Taking a high- density, high-quality urban districts in Shanghai as an example, this study proposes a pathway for implementing key technologies for near-zero carbon urban districts through a dual approach of “carbon source reduction” and “carbon sink enhancement,” summarized as the “Two-Lows and Four-Aspects” strategy（low-energy buildings, low-emission transportation, resource circulation, ecological landscaping, energy maximization, and digital management ） . Additionally, the feasibility of achieving near-zero carbon emissions in high-density urban districts is calculated and validated, providing a practical reference for similar high-density urban projects aiming for near-zero carbon emissions.
