Summary of "Addressing Climate Change in Transport" - Volume 1: Pathway to Low-Carbon Transport

Core Content

This report, Addressing Climate Change in Transport - Volume 1: Pathway to Low-Carbon Transport, is part of the Vietnam Transport Knowledge Series and is supported by the Australia-World Bank Group Strategic Partnership in Vietnam, the Government of Germany, and the NDC Partnership Support Facility. It presents a comprehensive analysis of Vietnam's transport sector in the context of climate change, focusing on strategies to reduce greenhouse gas (GHG) emissions and promote low-carbon development.

The report outlines three scenarios for the transport sector's future development, each with increasing levels of ambition and international support. These scenarios aim to assess the potential for emissions reduction, the associated costs, and the feasibility of implementing climate-smart transport solutions.

Main Objectives

• To analyze the current and projected state of Vietnam's transport sector.
• To evaluate the effectiveness of various mitigation measures in reducing GHG emissions.
• To provide policy recommendations for a low-carbon and resilient transport system in Vietnam.
• To support the Government of Vietnam in updating its Nationally Determined Contribution (NDC) and developing its next medium-term public investment plan (2021–2025).

Key Findings

Scenario 1: With Domestic Resources Only

• Mitigation Measures: Includes promoting biofuel, electric motorbikes, new vehicle fuel economy standards, expansion of bus systems, and improvement of truck load factor.
• Emissions Reduction: Under this scenario, GHG emissions are projected to decrease significantly, though not as much as in more ambitious scenarios.
• Marginal Abatement Cost (MAC): The cost of implementing these measures is calculated and presented, showing the cost-effectiveness of each option.
• Conclusion: This scenario is a baseline for reducing emissions using only domestic resources, but further international support is needed for more substantial reductions.

Scenario 2: Increasing Ambition with International Support and Private Sector Engagement

• Mitigation Measures: Builds on Scenario 1 by incorporating international support and private sector involvement. Measures include promoting electric buses, BRT systems, metro systems, electric cars, and modal shift from road to rail and inland waterways (IWT) and coastal shipping.
• Emissions Reduction: This scenario leads to more significant reductions in GHG emissions compared to Scenario 1.
• MAC: The cost of each measure is calculated, showing that with increased support and engagement, the cost of mitigation decreases.
• Conclusion: This scenario represents a more ambitious approach, leveraging both domestic and international resources, and private sector involvement to achieve lower emissions.

Scenario 3: Pushing Sector Transformation with Larger International Support and Strong Private Sector Engagement

• Mitigation Measures: The most ambitious scenario, including the deployment of metro systems, electric cars, and electric buses, as well as modal shift from road to rail and IWT/coastal shipping.
• Emissions Reduction: This scenario achieves the most substantial reduction in GHG emissions, with projections showing a significant decrease in emissions compared to the Business-As-Usual (BAU) scenario.
• MAC: The marginal abatement cost is the lowest in this scenario, indicating the most cost-effective approach to emissions reduction.
• Conclusion: Scenario 3 emphasizes a transformative approach to the transport sector, which requires substantial international support and active private sector participation to achieve deep decarbonization.

Business-As-Usual (BAU) Scenario

• Projection: Under BAU, Vietnam's transport sector is expected to see rapid growth in vehicle numbers, especially motorbikes, and a significant increase in GHG emissions.
• Emissions Growth: By 2030, GHG emissions from transport are projected to triple to nearly 90 million tons CO₂e.
• GHG Emissions Trends: Emissions are growing disproportionately to the size of the economy, with Vietnam being the 13th most carbon-intensive economy globally.
• Transport Development: The sector is expanding, with increasing road networks, but this expansion is also contributing to vulnerability to climate hazards.

Cost of Implementation

• The report uses the Marginal Abatement Cost Curve (MACC) to evaluate the cost-effectiveness of various mitigation measures.
• Key Measures and Costs:
  • Biofuel Promotion: Cost estimates and cost-benefit analysis are provided.
  • Electric Motorbikes: Costs and benefits are analyzed, showing potential for significant emissions reduction.
  • New Vehicle Fuel Economy Standards: Cost assumptions are detailed.
  • Expansion of Bus Systems: Includes cost estimates for bus routes and electric buses.
  • Deployment of BRT and Metro Systems: Cost assumptions for different technologies are presented.
  • Modal Shifts: Costs for shifting freight from road to IWT and coastal shipping, and from road to rail are analyzed.
  • CNG Buses: Cost assumptions and MACC results are included.
  • Truck Load Factor Improvement: Cost estimates and MACC results are provided.
• MACC Results: Each scenario's MACC is analyzed for the periods 2014–2030 and 2014–2050, showing the potential for emissions reduction and cost savings.

Policy Recommendations

• The report recommends a combination of domestic and international efforts to achieve a low-carbon transport system.
• Key Recommendations:
  • Implement new vehicle fuel economy standards to reduce emissions from private vehicles.
  • Expand public transport systems, including buses, BRT, and metro.
  • Promote electric vehicles (motorbikes, buses, and cars) to reduce reliance on fossil fuels.
  • Encourage modal shift from road to rail and IWT to reduce emissions from freight transport.
  • Introduce CNG buses as an alternative to diesel and gasoline-powered vehicles.
  • Improve truck load factor to enhance efficiency and reduce emissions.
  • Strengthen climate resilience of the transport network to mitigate future climate risks.

Support and Collaboration

• The report was prepared by the World Bank and GIZ, with support from the Vietnam Ministry of Transport.
• It was part of the International Climate Initiative (IKI) and the TraCS (Transport Climate Strategies) project.
• Collaboration with government agencies, universities, and international organizations contributed to the report's findings and recommendations.

Conclusion

The report highlights the urgent need for a low-carbon and resilient transport system in Vietnam. It presents three scenarios, each with increasing ambition and support, to guide policymakers in making informed decisions. The findings emphasize the importance of policy integration, private sector engagement, and international collaboration in achieving sustainable transport development. The report also provides a methodological framework for analyzing transport emissions and resilience, which can be used in future planning and investment decisions.
