Climate Tech Funding Jumps 55% to Reach $26.1 Billion in First Half of 2026

Climate tech companies around the world attracted $26.1 billion during the first half of 2026, an increase of 55% compared to the same period in 2025, according to data tracking investment flows in this sector.

Renewable energy and energy storage solutions topped the list of sectors attracting the most investment, alongside carbon capture technologies and energy efficiency in buildings and industry, amid rising regulatory pressures and growing demand for sustainable solutions.

Institutional capital flows and government climate funds contributed to boosting this momentum, with increasing demand from investors for startups capable of delivering scalable solutions with real economic viability.

Specialists note a shift in investor perspective, as climate tech is now treated as a promising economic opportunity rather than a purely environmental obligation, which explains this unprecedented acceleration in funding volume.
