Recognised by this year's judging panel as a clear leader in energy-related infrastructure investments, Mirova has constructed an investment platform dedicated to the energy transition.

In developed markets, Mirova launched Mirova Energy Transition 6 (MET6) at the end of 2023, a sixth vintage focusing on strategic investments in infrastructure projects across clean energy production (solar PV, wind, hydro, hydrogen), energy storage, and energy usage (energy efficiency, low carbon mobility) in Europe & OECD countries. The fund reached a second successful closing at €1.2bn ($1.4bn) in August 2025.

In emerging markets, the Mirova Gigaton Fund (MGF) seeks to accelerate energy transition primarily in Sub-Saharan Africa and South-East Asia by providing private debt financing to businesses active in solar power for homes, agriculture, mini-grids, e-mobility, SMEs and other green energy sectors.

The fund has reached approximately 93% of its $350m target size, with $326m committed to date, following a fifth closing in June 2025.
