Environmental Finance's Sustainable Investment Awards judges singled out boutique investment manager, Osmosis Investment Management for the second year in a row, citing its "great fund" and "impressive performance".

The UK-based environmental asset manager has tripled its assets under management (AUM) to $10 billion over the course of the year, including winning a mandate for $4.5 billion from Dutch pension fund, PGB, described at the time as one of the largest ESG mandates.

The Osmosis research process standardises unstructured corporate environmental data, in the construction of its 'Resource Efficiency Factor'.

It considers the significance of carbon, water, and waste data at a granular level enabling measurement of a company's sustainable actions, rather than its intentions.

Osmosis says it is focused on delivering three levels of impact: better risk-adjusted returns, measurable environmental reductions, and an active engagement programme to promote better corporate environmental disclosure.

The firm says its approach led to reductions in carbon of 57%, water of 66% and waste of 71% at the end of March 2023 in its flagship Core Equity Fund, relative to the MSCI World.

"The team at Osmosis is incredibly proud to win the Boutique investment manager of the year award for the second year running. It's a testament to the 14 years of work we have committed to proving that investing sustainably can also deliver better risk-adjusted returns," commented Ben Dear, chief executive officer, Osmosis Investment Management.

"As our assets under management scale beyond $10 billion, we may not be included in next year's awards in this category, but we look forward eagerly to being judged amongst our peers in the larger manager category. I'd like to thank all our stakeholders but especially our clients for their continued trust and support and of course, my team for their enduring commitment to making Osmosis an industry-leading sustainable asset management company."
