Why Climate Investing Is Increasing

Climate focused investment continues its rise and is attracting increasing attention across financial markets. A recent analysis by BCG confirms this trend. 

In 2024, private equity transactions linked to the climate sector reached $73 billion. At the same time, fundraising for climate funds grew by 20 percent compared to the previous year. This happened in a context where global private equity overall fell by 18 percent. 

This contrast signals a shift in direction. Capital is increasingly flowing toward projects and technologies that provide solutions to climate change. And large institutional investors are also joining this movement. 

A survey by S2G Investments revealed that nearly half of investors plan to expand their positions in climate related initiatives. Among them is CalPERS, which recently decided to double the size of its mitigation, adaptation, and transition fund to 100 billion dollars. 

What is driving this growth? 

The main driver is economic. More than half of low carbon technologies are already cost competitive with conventional alternatives, and a significant group is on the verge of achieving that benchmark. Technological advances have lowered risks and opened the door to investments supported by solid fundamentals. 

At the same time, pressure to manage climate risk is rising. Supply chains exposed to extreme weather, tightening regulations, and rising societal expectations are all creating a more favorable position for companies with credible transition plans. 

The breadth of sectors involved also adds momentum. It is not just about renewable power generation but also smart grids, charging infrastructure, energy efficiency services, storage, advanced recycling, bioenergy, alternative proteins, carbon capture, and financial solutions adapted to the transition. This diversification multiplies investment opportunities and reduces dependence on any single segment. 

Opportunities taking shape 

In energy infrastructure, smart grids and digitalization stand out as highly attractive areas. A clear example is Suma Capital’s SC Net Zero Ventures I fund, which reached 210 million euros and is already investing in companies like Corinex, focused on grid digitalization, and V2C, specialized in electric vehicle charging solutions. 

Energy efficiency is another fast-growing front. Companies offering guaranteed savings contracts and energy as a service models are gaining traction in various markets. Sapphire Technologies fits this approach with its turboexpander technology, which converts residual energy into clean electricity. Its recent 18-million-dollar Series C round will expand production capacity and diversify applications across industry. 

The circular economy also ranks among the segments with the highest potential. Xampla, a spin out from the University of Cambridge, raised 14 million dollars to scale natural materials that replace single use plastics. This innovation aligns with BCG’s outlook on advanced recycling and material substitution. 

Direct air capture is another technology beginning to consolidate. Brineworks secured 6.8 million dollars to scale its air capture solution designed for e fuel production. The company’s goal is to bring capture costs below 100 dollars per ton, a milestone that could transform the economics of hard to electrify sectors. 

These are only a few examples of how the opportunities highlighted by BCG are taking shape. The climate investment landscape is much broader, spanning advanced storage, flexibility management in power grids, biofuel development, low emission industrial heating, and the expansion of sustainable finance platforms, among many others.  

The integration of tangible projects with new opportunities indicates that climate investment is moving into a more mature phase. 

This momentum is unfolding at multiple levels. Large investors are channeling resources into strategic sectors, while emerging ventures are demonstrating the technical and financial viability of innovative solutions. It is this convergence that sustains growth. 

The years ahead will be decisive in consolidating this trajectory.
