Investment in infrastructure is critical for achieving the energy transition, requiring trillions of dollars over the coming decades. Alexia Savva from Infracapital highlights the importance of identifying sustainable investments amid a changing regulatory landscape and the risk of greenwashing. Significant private capital is needed, particularly in Europe, where key sectors like transport and industry contribute heavily to emissions. Opportunities include electrification, hydrogen, and carbon capture. Sustainability considerations, such as biodiversity and human rights, are essential. New regulations and market dynamics offer potential, but the challenge lies in balancing long-term infrastructure needs with immediate sustainability goals.
