Summary of City Energy Efficiency Report: Wuhan Transport Sector

Core Content

This report evaluates the energy efficiency of Wuhan's transport sector using the TRACE tool, which is part of the Energy Sector Management Assistance Program (ESMAP). The analysis highlights the importance of improving energy efficiency in transport for sustainable urban development, particularly in the context of China's rapid urbanization and increasing energy demand. Wuhan, a major inland city with a population of 10.22 million in 2013, faces challenges related to high energy consumption, traffic congestion, and air pollution due to its growing vehicle fleet and relatively low public transport usage.

Main Findings

• High Energy Consumption: Wuhan has relatively high per capita electricity and energy consumption, ranking 3rd in the TRACE database among cities with similar continental climates.
• Transport Energy Use: In 2013, transport accounted for 16.6% of Wuhan’s total energy use, with private vehicles contributing 64.9% and public transport 31%.
• Energy Efficiency Gaps:
  • Public transport energy consumption was 0.51 MJ/passenger km, lower than private vehicles at 2.14 MJ/passenger km.
  • The average length of high-capacity transit routes per 1,000 people was low, at 11.7 meters.
  • Public transport mode split was 30%, placing Wuhan in the lower middle range compared to peer cities, with a target of reaching 50% by 2020.
• Potential Savings:
  • Public transport could save up to 31% of its energy use.
  • Private vehicles could save up to 20.2% of their energy use.
  • Estimated potential energy cost savings: USD78.4 million for public transport and USD169.9 million for private vehicles.

Key Information

• TRACE Tool: A decision-support tool used to evaluate energy efficiency across sectors, including transport, municipal buildings, water and wastewater, street lighting, solid waste, and power and heat.
• Project Context: The report is part of the Wuhan Integrated Transport Development Project, supported by the World Bank and ESMAP.
• Implementation Support: The project team included experts from The World Bank's Transport and ICT East Asia and Pacific Unit.
• Limitations of TRACE: While it provides a quick and low-cost evaluation, it lacks detailed city-specific cost data for recommended strategies.
• Energy Sources: Wuhan primarily relies on fossil fuels for energy, which contributes to higher GHG emissions.
• Urbanization: Wuhan's urbanized population increased from 63.6% in 2007 to 67.6% in 2013.
• Transport Mix: In 2013, 23% of trips were by bus, 7% by metro, 6.5% by taxi, 20% by private cars, 18.5% by bicycle (including e-bikes), and 25% by walking.

Conclusion

Wuhan's transport sector is a significant contributor to energy use and GHG emissions. The TRACE tool provides a framework for identifying energy-saving strategies, emphasizing the need for a combination of public transport development, traffic flow optimization, and non-motorized transport promotion. These measures can be implemented in conjunction with existing projects and policies, offering substantial cost savings and environmental benefits. The city's energy consumption is relatively high, but with targeted interventions, it has the potential to achieve meaningful reductions in transport-related energy use and emissions.
