Tunnelling into a Sustainable Future – Methods and Technologies contains the contributions presented at the ITA-AITES World Tunnel Congress 2025 (Stockholm, Sweden, 9-15 May 2025). The contributions cover a wide range of topics in the fields of tunnelling and underground engineering, including:

1. Innovating tunneling

2. Safety Underground

3. Use of underground space

4. Investigations and ground characterisation

5. Planning and design of underground space

6. Conventional tunnelling

7. Mechanised tunnelling

8. Complex geometries including shafts and ramps

9. Grouting and groundwater control

10. Instrumentation and monitoring

11. Operation, inspection and maintenance

12. Contractual aspects, financing and risk management

13. Impact from climate change

Tunnelling into a Sustainable Future – Methods and Technologies will serve as a valuable reference to all concerned with tunnelling and underground engineering, including students, researchers and engineers.
