Top 10: Impact Investing Platforms

The annual SDG financing gap has grown by 60% to US$4tn, driven by climate urgency and geopolitical instability, according to the OECD’s Global Outlook 2025.

To bridge this gap, the world’s largest asset managers are deploying transition and impact finance at scale.

Low-carbon private investments have grown 123% over five years according to MSCI, and these investments are delivering returns that outpace the general private market.
