At the G7 Leaders’ Summit in Cornwall, UK, in June 2021, His Majesty King Charles III, then The Prince of Wales, and the Sustainable Markets Initiative (SMI) shared market signals to accelerate the transition. This was followed by a similar presentation at the G20 Leaders’ Summit in Rome in 2021. In 2022, 2023, 2024, and now 2025 the SMI continues to share its market signals and its call for direct private sector CEO engagement with G20 Leaders. 

At the SMI, we recognise that it will take trillions of dollars annually to make the transition to a low-carbon and Nature-positive economy. The good news is the private sector is already directing trillions in the right direction and is eager to lean in, across all industries, and to partner with governments in all regions of the world. 

While this updated market signals document is targeted at G20 Leaders, it is also inherently a Call to Action for the global private sector. We must retain high levels of ambition, speed and scale regardless of shifting political landscapes. Like no other time in human history, it is time for the private sector to lead.
