Earth Capital
Earth Capital is a London-based sustainable-investment firm, founded in 2008, that backed clean technology across energy, food, and water through its proprietary Earth Dividend impact model. The one water company (don't) Waste Water tracks is Propelair, a low-water-flush toilet maker. As of January 2025 the Earth Capital brand and Earth Dividend model were acquired by advisory firm Stakeholderz.

The take
Earth Capital was built in 2008 by Gordon Power and Stephen Lansdown around a single conviction: that an investment's contribution to the planet could be measured as precisely as its financial return. That measuring stick became the Earth Dividend, a proprietary sustainability score the firm ran across every company in its energy, food, and water portfolio, from renewable power to agriculture to water efficiency.
Earth Capital is best filed, for a newcomer, under sustainable private equity rather than water. Water reached it the way it reaches most generalist climate investors, through one good company instead of a dedicated thesis. The single water company (don't) Waste Water tracks is Propelair, an Essex business whose toilet flushes on roughly a litre and a half of water instead of the usual six to nine, backed through Earth Capital's Nobel Sustainability Fund across two rounds.
Earth Capital changed shape in January 2025, when its name and the Earth Dividend model passed to Stakeholderz, a London advisory firm that now runs the brand as a fundraising and M&A practice rather than a fund. Gordon Power handed over the name and joined the new advisory board; the investing history, Propelair included, belongs to the original Earth Capital Holdings.
Earth Capital, for a water founder reading this today, is a door to capital more than the capital itself: an advisory shop that still scores sustainability with the Earth Dividend and still speaks the language of energy, food, and water. The water track record is real but thin, one company deep, and the open question is whether the advisory chapter routes more water deals through the door than the fund ever wrote.
