News: Principles of Responsible Investment (PRI) marks its 20th Anniversary with the Opening of the London Stock Exchange (LSE)

London, ENGLAND (Exchange News) -- UN PRI is the world's leading network for responsible investment. With more than 5,000 signatories representing almost US$140 trillion in assets under management, the PRI brings together investors globally to strengthen how they manage risk and deliver long-term value.

On this day in 2006, then UN Secretary-General Kofi Annan, surrounded by a small group of forward-thinking investors, opened the New York Stock Exchange and launched the PRI. Twenty years on, responsible investment has moved from a niche idea to a mainstream part of global investing.

Today, investors are operating in a more complex and fast-changing environment, shaped by geopolitical shifts, technological disruption and environmental pressures. As a result, many of the risks that matter most to long-term returns can no longer be fully understood through traditional financial analysis alone.

LSEG's FTSE Russell, was a founding PRI signatory back in 2006. Today, the London Stock Exchange is pleased to host the opening of the market to mark the PRI's 20th anniversary, kicking off a global series of events across major financial centres.

Cambria Allen-Ratzlaff, PRI's Interim CEO, said: "Over the past twenty years, responsible investment has become a core part of how investors understand risk and return. But the world has changed. Today's risks are more complex, more interconnected, and in many cases harder to diversify away. This milestone is an opportunity to reflect on progress and consider how responsible investment must continue to evolve to meet this challenge."

We are honoured to host this special anniversary with PRI, particularly in a year that also marks an important milestone for LSEG, as our sustainable finance offering reaches 25 years since the launch of the FTSE4Good Index Series in 2001. It is a timely moment to take stock of the progress that has been made, while also reflecting on emerging challenges and how lessons from the past can help shape the next phase of sustainable finance.
