The Carbon Credit Finance Revolution – How India's First Carbon-Backed Debt Facilities Are Reshaping Climate Investment
Introduction: The New Frontier of Climate Finance
A quiet but powerful shift is underway in India's climate finance landscape. Carbon credits are no longer just environmental assets—they are becoming bankable financial instruments that can secure debt, attract equity investment, and unlock billions in sustainable finance.
In a pioneering move for India's climate finance sector, Iora Ecological Solutions (IORA) secured a significant debt facility totaling ₹8.5 crore, marking India's first carbon credit-backed debt facility from Caspian Impact Investments. This transaction demonstrated that lenders are willing to accept future carbon credit revenues as collateral.
The momentum is building. Varaha, an India-based carbon dioxide removal company, opened a new financing round with an initial $20 million investment led by WestBridge Capital, targeting approximately $45 million in total funding. The company has previously signed carbon removal agreements with Google and Microsoft, including a 100,000-tonne biochar removal agreement with Microsoft over three years.
RenewCred, a Bengaluru-based climate technology startup, secured equity and grants totalling ₹42.5 million (~$471,000) in a seed funding round.
The India carbon credit market is estimated to be valued at USD 5.90 billion in 2026 and is expected to reach USD 66.79 billion by 2033, exhibiting a compound annual growth rate (CAGR) of 41.4%.
This guide examines the revolution in carbon project finance—the deals, the players, the economics, and what project developers must do to attract investment.

Under the arrangement, Japanese investment and technology can help fund projects in India that reduce or remove greenhouse gas emissions. Carbon credits can also be shared between the two countries to help meet their climate targets.
The Governance Structure
The Rule of Implementation defines robust governance arrangements, including:
- A Joint Committee with representatives from both governments
