Suma Capital has published its 2025 Sustainability Report, which reflects the consolidation of its investment platform specializing in the ecological transition. During the year, the firm surpassed €1.1 billion in assets under management and expanded its portfolio to 44 companies after investing in eight new companies. This reinforces its investment model focused on driving decarbonization and the circular economy.
In 2025, the investments made by the company helped prevent the emission of 628,360 metric tons of CO₂ equivalent. In addition, they generated 110.4 GWh of renewable energy, processed nearly 1.7 million metric tons of waste, and enabled the reuse or recovery of more than 168,000 cubic meters of water.
Suma Capital ended the fiscal year with 12 funds and investment strategies managed through SC Infra, SC Expansion, and SC Venture. The companies in which the firm holds stakes generated aggregate revenues of 648 million euros and employed nearly 3,000 people.
Sustainability is an integral part of Suma Capital’s investment model, from identifying opportunities and assessing risks to actively managing portfolio companies. In line with this approach, in 2025, 53.6% of the firm’s investment went to projects related to circularity and resources, 22.8% to the energy transition, 11% to the digital transition, and the remaining 12.6% to initiatives related to the sustainable economy and social cohesion.
At the same time, Suma Capital adopted the Net Zero Investment Framework (NZIF), a methodology developed by the Institutional Investors Group on Climate Change (IIGCC) that enables the assessment of assets’ climate alignment and supports portfolio companies in their transition and decarbonization processes toward the 2050 Net Zero goal. The framework incorporates a climate maturity scale to evaluate the status of each asset and define goals and plans for a gradual transition, integrating climate criteria into all phases of the investment cycle.
“The transition to a decarbonized economy is the path to simultaneously strengthening Europe’s energy sovereignty and competitiveness. At Suma Capital, we continue to invest in assets and companies capable of driving that transition in the real economy, with a long-term vision and rigorous risk management”, says Enrique Tombas, president of Suma Capital.
In addition, the company launched the Suma Impact Foundation, a philanthropic initiative aimed at contributing to a just transition through projects focused on climate resilience, the regeneration of the natural environment, and the promotion of more sustainable lifestyles.
The Annual Report also highlights milestones such as the final closing of SC Net Zero Ventures I, with €210 million committed, and the launch of the Gestcompost follow-on fund, with €250 million in assets. Furthermore, the management firm strengthened its European presence by opening an office in Milan.
With nearly two decades of experience, Suma Capital continues to strengthen its investment platform specializing in the green transition, relying on sound investment discipline, active risk management, and impact measurement to support the growth of companies and infrastructure projects capable of generating long-term value.
