Frequently Asked Questions

Calculus Carbon is an institutional advisory firm for natural capital, incorporated in 2022 and headquartered in Bangalore with offices in London and Singapore. The firm structures equity, structured debt, and project finance mandates for nature-based solutions sponsors across the Global South. Calculus Carbon is backed by Info Edge Ventures, a Temasek portfolio company.

Calculus Carbon was founded by Neelesh Agrawal, who serves as CEO. Neelesh brings experience from telecom investment banking, infrastructure fund management, and regenerative agriculture before founding Calculus Carbon to focus on institutional market making for natural capital.

Institutional market making for natural capital refers to the practice of connecting large-scale Nature-Based Solutions (NBS) project sponsors with institutional capital providers such as infrastructure funds, family offices, and development finance institutions. Calculus Carbon acts as a sell-side advisor, structuring the full capital stack — equity, structured debt, and project finance — to help sponsors scale their underlying natural capital assets.

Calculus Carbon advises on mandates across the Nature-Based Solutions spectrum, including agroforestry, mangrove restoration, biochar, peatland rehabilitation, and other land-use projects. Each mandate involves structuring financing across equity, structured debt, and project finance to meet the sponsor's capital requirements.

Calculus Carbon operates across the Global South, with active mandates and regulatory coverage in Indonesia, India, Brazil, Kenya, Mexico, Nigeria, Philippines, Malaysia, South Africa, Vietnam, Peru, and Cote d'Ivoire. The firm has offices in London (UK), Singapore, and Bangalore (India).

Calculus Carbon is not a fund — it is an advisory firm. Unlike carbon funds such as Pollination or Climate Asset Management that raise and deploy capital directly, Calculus Carbon acts as a sell-side investment banker, connecting NBS sponsors with the right capital partners. The firm earns advisory fees for structuring and placing mandates, not management fees on assets under management.

Project developers originate and operate carbon credit projects on the ground. Calculus Carbon does not develop projects. Instead, the firm works with established project developers and NBS sponsors to structure and raise the financing they need to scale. Calculus Carbon sits between the sponsor and the capital markets.

Calculus Carbon typically works with institutional-scale mandates. The firm focuses on large-scale NBS sponsors seeking equity, structured debt, or project finance at ticket sizes appropriate for institutional investors, infrastructure funds, and development finance institutions.

Calculus Carbon works with projects registered or seeking registration under leading voluntary carbon market standards, including Verra (VCS), Gold Standard, and other recognized certification bodies. The firm's regulatory hub covers the compliance frameworks across 9 countries.
