Impax Asset Management is a leading investment manager dedicated to investing in the opportunities created by the scarcity of natural resources and the growing demand for cleaner, more efficient products and services, through both listed and private equity strategies.

Impax's listed equity funds seek out mis-priced companies that are set to benefit from the long-term trends of climate change, inadequate infrastructure, environmental constraints, changing demographics, urbanisation 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, sustainable food and agriculture and related markets.

As part of our investment process, we develop and maintain a large database of our entire investment universe, currently c. 1,600 companies. We review and update the exact % of revenue (or other business activity indicator) derived from the resource efficiency and environmental markets for each company on an annual basis. This process ensures that our investee companies are and continue to be part of the economy and sectors benefiting from resource and environmental opportunities and to further develop and expand our investment universe. The companies we invest in must derive at least 50% or 20% of revenues (depending on the strategy) from the resource efficiency and environmental sectors.

One person in the Impax investment team is dedicated to maintaining and developing our investment universe.

Impax is a thought leader in defining the markets in which we invest, for example through a partnership with FTSE to develop and manage the classification system underpinning the FTSE Environmental Markets Index Series.
