Investing in the energy transition to accelerate the shift from fossil fuels to clean, inclusive and affordable energy systems

Measurable impact

For professional investors focused on sustainability, renewable energy investments deliver measurable impact, strong alignment with the UN SDGs and increasing appeal among clients and stakeholders.

Proven technologies

The energy transition is well underway. This creates a strong and growing demand for infrastructure, innovation and energy solutions that are already technologically and economically viable. For you as investor, this translates into a wide range of opportunities, from utility-scale solar parks and (repowering of) wind projects to smart grids and battery storage, all backed by reliable track records and long-term contracts.

Attractive risk/return profile

Infrastructure-like renewable energy projects often provide stable, inflation-linked returns with relatively low correlation to traditional assets classes. This makes them attractive for diversification and risk management in your portfolio.

Our first onshore wind investment dates back to the 1980s. Since then, we have established ourselves as pioneering investors in Energy and Climate. Our strategies are actively managed with a long-term vision, aimed at generating positive impact and risk-adjusted returns for retail, professional and institutional investors.

Our Energy and Climate team is composed of experienced fund managers and an international team of investment managers. Meet the Energy and Climate fund managers.
