India’s climate technology sector has attracted around $12.8 billion in cumulative funding across 1,583 companies, driven by rising energy security concerns, policy support and private capital, according to a Tracxn report.
annual investment in the sector has grown sharply from about $315 million in 2020 to $2.6 billion in 2025, re?ecting increasing alignment between climate goals and India’s push for energy independence. Renewable energy remains the largest segment, drawing about $1.5 billion in cumulative funding, followed by waste management, energy ef?ciency, air pollution control and water treatment technologies.
the report notes that investment is increasingly concentrated in fewer but larger late-stage deals, signaling a maturing ecosystem focused on scale and deployment. Key government initiatives such as EV adoption programmes, carbon trading mechanisms and rare earth supply chain support are also strengthening investor con?dence in the sector
