About Us

Osmosis launched in 2009 and is majority owned by management and employees. The company is headquartered in London with a growing presence in North America. Our philosophy is that for sustainable investment to gain mainstream adoption, positive environmental impact should not come at the cost of portfolio performance.


Our team of quantitative environmental analysts and portfolio managers are singularly 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.


Government Pension Funds, State Pension Funds, Insurance Companies, Foundations, Endowments, Family Offices and Banks, are amongst our client roster spanning North and South America, Mainland Europe, Nordics, Australia, Asia and the UK.

We target three pillars of impact

Environmental Research

Our objective approach to environmental investment is driven by over a decade of proprietary research enabling the construction of our proprietary sustainable investment factor. Research, both internal and external, has demonstrated that our Resource Efficiency factor is uncorrelated to other common factors and is a predictor of future firm value.

As companies globally set increasingly ambitious Paris aligned or Net Zero targets, our objective research process effectively measures a company’s sustainable action vs its sustainable intent. In order to meet our clients’ goals, we utilise this sustainable investment factor as the core source of financial and environmental return across all of our funds and strategies. Our portfolios overweight efficient companies and underweight, or short, inefficient companies, while targeting specific risk profiles and investment styles.

Importantly, all our portfolios demonstrate significantly less ownership of Carbon, Water and Waste than their respective benchmarks.

Resource Efficiency

Enables high-quality companies with strong management teams to generate a competitive advantage

Captures the intangible value of environmental resilience and mitigates long-term climate change risk

Identifies companies that are transitioning to a greener economy and have lower environmental risks

Our Environmental Impact

The Resource Efficiency Signal generates a significant reduction in the resource footprint of all our portfolios relative to their benchmarks. Osmosis’s strategies save an average reduction of – 56% in carbon, -62% in water, and -68% in waste, relative to their benchmarks (as of 31 March 24).
