Carbon dioxide management in a major UK infrastructure project: High Speed Two.

High Speed Two, a planned high-speed railway in the UK, could play a key role in reducing national greenhouse gas emissions. The project has adopted whole-life carbon dioxide emissions reduction as a core project value and is using the PAS 2080 specification to implement carbon dioxide management. Effective leadership and governance, metrics, innovation and standards, and commercial solutions underpin the approach. This paper outlines the carbon dioxide management work undertaken to date, describes the proposed next steps to enhance the approach and summarises the lessons learned for other infrastructure projects.
