Environmental-focused private equity firm Ambienta has reportedly hold another interim close for its latest fund, Ambienta II.

The Milan-headquartered firm has raised €250 million for the fund. In January this year the Ambienta II fund hit a €200.2 million second close, a few months after holding a €147.2 million first close.

Ambienta II has been supported by a broad range of investors, including Italian, Nordic and international pension funds, insurance companies, fund of funds and family offices. International investors based in Europe and North America accounted for around 40 per cent of total commitments.

Ambienta II will invest in European companies focused on resource efficiency, gas and pollution-control technologies. The fund will invest in 10-15 companies. International expansion will be the central fund strategy; more than 85% of revenues generated by portfolio companies in Ambienta I originate outside of Italy.

Ambienta had three partners based in Milan when it raised the first fund. This time, the firm has two hubs - Milan and Munich - and a base in London, as well as 14 people. Ambienta's first fund raised €217.5 million in 2009 and has investment between €10 million and €30 million per deal.

Headquartered in Milan, Italy and led by Nino Tronchetti Provera, Managing Partner & Founder, Ambienta has invested in Tattile, Found Ocean, Amplio Filtration Group, MBA Polymers, Spig, Ravelli, Icq Holding, and Ambienta Biomasse. It recently divested Tower Light.
