Winners include leaders in equities, fixed income, multi-asset and thematic strategies, along with the best overall asset manager and boutique manager.

Neill Blanks, MainStreet Partners’ head of funds research, commented: “At the start of 2024, you may have been forgiven for thinking we would see less regulatory complexity than 2023. Unfortunately, that was far from the case, not least as fund naming rules came into effect on both sides of the Atlantic.
“Regulatory scrutiny continues to intensify, with the threat of fines being imposed for those that do not adapt as well as the associated reputational damage.
“To further help our clients avoid the risk of greenwashing, we introduced another sub-pillar into our rating methodology called ‘EU Regulatory Alignment’. It combines key data points from the European ESG Template (EET) with an assessment of how Asset Managers are defining what is a ‘Sustainable Investment’.
“In an ever-evolving market, the asset managers who choose to take a proactive approach and utilise technology will be the ones to prosper. These awards recognise some of the most pioneering asset managers and funds in the industry.”
Rachel Whittaker, Robeco’s head of SI research, commented: “We are very honoured to have been recognised as one of the best ESG and Sustainability Asset Managers by MainStreet Partners.
“Now more than ever, sustainable investing is crucial as it aligns financial growth with environmental stewardship and social responsibility.
“By investing in sustainable assets, we not only seek to generate long-term returns but also contribute to a healthier planet and more equitable society for future generations.”
