ITF Transport Outlook 2023 Summary

Introduction

The ITF Transport Outlook 2023 examines global transport trends and future prospects under two policy scenarios: Current Ambition and High Ambition. It focuses on decarbonizing transport by 2050 to align with Paris Agreement goals, using in-house models to project impacts on demand and emissions.

Findings

Transport emissions are rising due to growing demand, with policies insufficient to meet climate targets. Under Current Ambition, passenger demand up 79% and freight almost double by 2050. High Ambition scenario shows moderate increases but emphasizes the need for accelerated decarbonization. Key issues include urban sprawl, energy dependence, and slow implementation of plans. Aviation and maritime sectors face high decarbonization costs.

Policy Recommendations

1. Develop comprehensive strategies for future mobility and infrastructure to favor sustainable options.
2. Accelerate transitions to clean vehicle fleets and alternative fuels, ensuring equitable access.
3. Implement mode shift and demand-management policies in urban areas.
4. Reform vehicle taxation to capture external costs and promote sustainable choices.
5. Adopt integrated land-use and transport planning to avoid sprawl and enhance walkability.
6. Increase investment in charging infrastructure and public transport.

Analysis of Future Scenarios

• Current Ambition reflects delayed action, leading to higher emissions.
• High Ambition scenario requires bolder policies, potentially reducing emissions through electrification and sustainable fuels.
• Regional differences exist, with urban areas prioritizing shared mobility and rural regions facing mode-shift challenges.

Investment Implications

Decarbonization could lower core infrastructure costs in some areas but demands significant funding for charging networks and sustainable alternatives. Fuel tax revenues decline, necessitating reforms like distance-based pricing.

Key Challenges

Time is short to limit global warming; disruptions like pandemics and conflicts exacerbate uncertainties. Policy makers must balance economic growth with environmental goals to ensure a livable and equitable transport system.
