Pathways for municipalities to achieve carbon emission peak and carbon neutrality: A study based on the LEAP model

China has played an active and constructive role in the global combat against climate change. Municipalities play a leading role in tackling global climate change. However, despite the global efforts to push for carbon neutrality, the pathway is not yet clear. Using the municipality of Bengbu as a case, this paper explores pathways for achieving carbon emission peak and carbon neutrality in order to reach a CO2 emission peak before 2030 in four Scenarios and develops a low emission framework taking into consideration the local economy, population, renewable resources, as well as the transport and energy sectors based on the Low Emissions Analysis Platform (LEAP) model. Meanwhile, the energy demand, the structure of the electric power generation, the CO2 emission, and the total cost in different Scenarios are simulated respectively. The result of this study provides insight on options for energy transformation for the period of 2020-2060. The results show that the industrial sector is the largest energy consumer. The growth rate of energy demand in the primary industry and industrial sector shows downward trends. The increasement of industrial electrification rate and coal generation phasing out are crucial to CO2 emission reduction. The large-scale deployment of renewable energy and the deployment of thermal power generation with CCUS are important for the electric power industry to achieve carbon reduction goals. Last but not the least, recommendations on energy planning for municipals to realize carbon emission peak and achieve carbon neutrality are provided.

Automated summary

This study explores pathways for achieving carbon emission peak and carbon neutrality, using the municipality of Bengbu as a case. It develops a low emission framework based on the Low Emissions Analysis Platform model, considering the local economy, population, renewable resources, as well as the transport and energy sectors. The results show that the industrial sector is the largest energy consumer and increasing the electrification rate and phasing out coal generation are crucial for CO2 emission reduction.
