A global leader in the transition to safe, sustainable energy

The world needs energy, but energy production needs to change. LetterOne (L1) is building a safe, sustainably growing energy group, recognised as a partner of choice in its industry and enabling the transition to a lower-carbon and more circular economy. We continue to look for active investments that can power society for the long term.

Tim Summers Quote

"Investment activity in the circular economy is significant and on the increase, as customers become ever more thoughtful about plastics, waste and the full cycle impact of all of our lifestyles."
