India's climate-tech startups have raised about $12.8 billion between 2008 and June 2026 across 1,583 companies, according to Tracxn's India Climate Tech 2026 Report.
The report points to growing momentum in the sector, with annual funding increasing from around $315 million in 2020 to $2.6 billion in 2025 as climate action, policy support, private capital, and energy-security goals increasingly align.
