About RAAI
The Responsible Asset Allocator Initiative (RAAI) is focused on mobilizing capital from the world’s largest investors, sovereign wealth, and public pension funds, to advance systemic change for a more sustainable world.

RAAI produces the RAAI Index, the first comprehensive benchmark of how sovereign wealth funds and government pension funds integrate environmental, social, and governance factors into their investment decision-making. Developed in partnership with the Fletcher School at Tufts University, the Index rates approximately 300 of the world’s largest asset allocators - representing over $30 trillion in assets - across 10 core principles and 30 criteria.
From the Index, RAAI publishes The Leaders List, ranking the highest-scoring institutions and identifying the top quintile of performers. Together, these asset allocators set a global standard of excellence for responsible investing and provide a benchmark for the broader investment community to follow. Since launching in 2016, the initiative has tracked steady progress - with average global scores rising across each edition - while highlighting the gap that remains between leaders and the rest of the field.
RAAI’s research informs investors, policymakers, and the broader responsible investing ecosystem. By making performance visible and comparable, the Index creates accountability and accelerates the shift toward capital allocation that delivers both financial returns and measurable progress on the world’s most pressing social and environmental challenges.
