A key part of our work is helping governments procure and develop large-scale infrastructure. The reason we get out of bed in the morning is to work on globally significant, first-of-a-kind projects.

How Stephen is building a better working world

"I provide financial and commercial advice to better help governments and corporations rise to the challenge of climate change and to facilitate or provide performance-based infrastructure, faster and more effectively. This may be through the construction of new sources of clean energy or through the development of climate resilient infrastructure that protects communities’ water and energy resources from climate risks."
