Impax Environmental Leaders

A fund managed by the largest independent environmentally focused investment house that looks to deliver a portfolio of stocks that play into resource efficiency themes.


The fund looks to buy stocks that fit into their themes of “resource efficiency”. Namely, they look for companies globally which generate at least 20% of their revenues from four sub-themes being energy, food & agriculture, water and resource recovery.

We like the fund as it is supported by one of the oldest and biggest environmentally focused investment houses, with exceptionally experienced team members. Their strong and tested investment process has helped to build a portfolio with a high exposure to environmental themes (around 60%) delivering strong revenue and earnings growth.
