Abstract

Abstract: This study takes the CO2 emissions from the energy consumption of 30 provinces in China as the research object. We predict and analyze a significant phenomenon involving the total CO2 emissions of inter-provincial energy consumption from the east to the west. On the basis of three CO2 emission reduction scenarios (Scenario 1: Baseline Scenario (10%–20% emission reduction target), Scenario 2: 2 °C Path Scenario (50%–60% emission reduction target), and Scenario 3: 1.5 °C Path Scenario (75%–85% emission reduction target)), a regional synergy scenario is proposed for the first time in this article. That is, the government develops multi-field CO2 regional synergistic emission reduction (RSER) based on regional industry coordination by rationally guiding the implementation of the "enclave economy." Moreover, we compare and analyze the different carbon emissions of the multiple "Carbon Neutrality" targets in 2050 under multiple scenarios. The results reveal that compared with scenario 1, scenario 2, and scenario 3, the regional synergy scenario can achieve 18.4%, 58.4%, and 83.4% reduction, respectively, compared with the current situation, which is significantly higher than the effect of the emission reduction targets set based on the average threshold values (15%, 55%, and 80%) of the above scenarios. Highlights: The study reveals a significant shift in the total CO2 emissions of inter-provincial energy consumption. The scenario of CO2 regional synergistic emission reduction has significant emission reduction potential. The study reasonably guides the implementation of the "enclave economy.". The classification management and control system for China's regional synergistic emission reduction has been established.
