Notes to Editors - About Impax Asset Management

Founded in 1998, Impax Asset Management is dedicated to investing in resource efficiency and environmental markets created by resource scarcity and the demand for cleaner, more efficient products and services. Impax, which employs 28 investment professionals and a similar number of support staff, has offices in London, Hong Kong, New York and Portland (Oregon). The firm manages ca. £3.0 billion* for investors globally across listed and private markets strategies.

Impax's listed equity funds seek out mis-priced companies that are set to benefit from the long-term trends of changing demographics, urbanisation, rising consumption, and the resultant increases in resource scarcity. Investment is focused on a small number of deeply researched global equity strategies across alternative energy, energy efficiency, water, waste, and food and agriculture related markets.

The private equity infrastructure funds follow an operationally focused, value-add strategy, investing in renewable power generation and related assets throughout Europe.

The Impax Climate Property Fund focuses on developing sustainable and energy efficient commercial property in the UK.
