This study examines the complex relationship between renewable energy penetration (REP) and CO 2 emissions in China, aiming to provide insights into deep decarbonization strategies. Using advanced robust pooled mean group-autoregressive distributed lag (PMG-ARDL) estimation, this paper analyzes long-run equilibrium short-run dynamics of REP based on panel data from 30 Chinese provinces (1997–2021). Wavelet coherence analysis (WCA) exploratory spatio-temporal (ESTDA) are also employed explore time-frequency relationships spatial correlation dynamics. The findings indicate that: (1) A 1% increase reduces long-term short-term carbon by 0.05% 0.26%, respectively. (2) more pronounced 1–2 year band. (3) exhibit opposing distribution patterns (−0.224), with distinct north-south clustering, dominated low-high low high (4) Most provinces’ LISA time paths demonstrate strong spatiotemporal stability, while Central, South, Southwest China a variability process, transitions, predominantly Type IV, reflect locking effects. offers policy suggestions for China’s low-carbon system lessons other economies.
