- Macquarie Climate Solutions Fund (IEYAX) is a global small/mid-cap equity mutual fund that seeks capital growth by investing primarily in securities of U.S. and non-U.S. issuers committed to reducing, displacing, or sequestering greenhouse gas emissions or enabling others to do so; its portfolio emphasizes companies with attractive risk-return profiles across sectors such as renewable energy, energy storage, clean fuels, carbon capture, electrified transport, distributed energy, and circular economy solutions, including holdings in utilities, infrastructure, and natural resources-related firms. The fund benchmarks its performance against the MSCI ACWI Investable Market Index and operates as a non-diversified vehicle with flexibility to concentrate up to 50% of assets in as few as two issuers; it targets institutional and retail investors focused on climate solutions within the global equity markets. Geographically, it invests worldwide, including developed and emerging markets in the Americas, Europe, Asia-Pacific, and beyond.
Launched in April 2006 and headquartered in Philadelphia, Pennsylvania as part of Macquarie Investment Management (MIM), a division of Macquarie Group Limited (Sydney, Australia), the fund underwent a significant strategic repositioning effective July 29, 2022, rebranding from Delaware Climate Solutions Fund to its current name, adopting a dedicated climate solutions objective, updated strategy, new benchmark, and refreshed investment team led by Macquarie Asset Management professionals. In late 2025, Macquarie Group completed the sale of its North American and European public investments business, including this fund, to Nomura for approximately $A2.8 billion, enabling a strategic partnership for product distribution and co-development of investment strategies while allowing Macquarie Asset Management to refocus on private markets. Recent portfolio-level developments within Macquarie's broader climate initiatives include the 2025 final close of its $3 billion Green Energy Transition Solutions Fund targeting similar emissions-reduction technologies and a 2024 acquisition by its Green Energy and Climate Opportunities Fund of a diversified portfolio of solar, wind, energy storage, and natural climate solutions projects representing over 17 GW capacity across the Americas, Asia-Pacific, and Europe.
