Impax Asset Management said heightened appetite for a more sustainable global economy sees it "well-placed for further growth" as it posted a 70% rise in pre-tax profits in the six months to 31 March compared to the same period last year.
Despite widespread uncertainty over trade and politics weighing on market sentiment, over the six months to 31 March Impax reported a 6% rise in assets under management (AUM), bringing total assets to £13.3bn, including £887m of net inflows.
Assets rose by a further £400m in the month of April alone, with total AUM now standing at £13.7bn, according to its latest trading update.
Historically, regulatory pressures have shaped demand for environmentally focused investment solutions, however chief executive Ian Simm pointed out how rising consumer interests - such as the war on plastics, changing food preferences and the expansion of the electric vehicle sector - are now influencing the sphere.
The specialist asset manager has increased its revenue by £8.1m over the period compared to H1 last year to £33.8m and grown its pre-tax profit by 69%, from £5.5m in H1 2018 to £9.3m over the first half of its 2019 financial year.
The group has also grown its interim dividend, taking it from 1.1p last year to 1.5p this year.
Simm added: "At the time of writing, market sentiment is overshadowed by uncertainty over global trade, particularly the relationship between China and the United States. Elsewhere, economic and financial market signals are mixed, and investor sentiment is fragile.
"Nevertheless, as investor interest in exposure to the sustainable economy continues to build, we are confident that Impax is well placed for further expansion."
