CLEAN: Collateralized Liquid Environmental Asset Note

A turnkey securitization solution to transform environmental projects into investor-grade financial instruments.

What is CLEAN?

Collateralized Liquid Environmental Asset Note (CLEAN) is a standardized, turnkey financial program that enables environmental projects to be issued as tradeable securities. Designed to cut through the complexity of traditional carbon markets, CLEAN packages all necessary legal, financial, and administrative components into a replicable model that reduces execution risk and accelerates capital deployment, often moving from intake to issuance in as little as three months.

Natural capital refers to the world’s stock of natural assets, such as forests, wetlands, grasslands, oceans, and soils, that provide critical ecosystem services. These include carbon removal, methane abatement, water purification, biodiversity protection, and other measurable climate and environmental outcomes. CLEAN enables these services to be structured and delivered as verifiable, financeable impact instruments.

  •       CLEAN delivers institutional-grade legitimacy in a simplified structure.
  •       Each issuance includes all core elements: SPV setup, legal documentation, and placement support wrapped into one replicable package.
  •       With built-in compliance, CUSIP/ISIN assignment, and LoA-backed environmental integrity, CLEAN offers a credible, tradeable alternative to legacy carbon offsets.

How the CLEAN Program Works

CLEAN helps developers transform qualified environmental projects into financial products that attract institutional capital. Whether you're launching a new project or retrofitting an existing one, our process is built for speed, simplicity, and credibility.

01
Project Intake

Issuers begin by submitting project materials through Entoro’s secure onboarding portal. Our team conducts a review to assess eligibility and fit for the CLEAN structure.

02
SPV Formation

A dedicated Special Purpose Vehicle (SPV) is formed and later transferred to the issuer for use in the transaction. This SPV serves as the legal issuer of the securities.

03
Financing Models

CLEAN offers two issuance structures to accommodate different capital needs:

• Prepay Model: Investors provide upfront capital in exchange for future delivery of environmental credits.

Project Finance Model: Capital is disbursed over time, tied to performance milestones, and administered via escrow and a trustee.

04
Structuring & Legal Execution

Entoro provides sample legal templates, leads the preparation for regulatory filings, and supports legal contracts. Instruments are structured to comply with U.S. private placement standards.

05
Placement & Issuance

The security is marketed to qualified institutional investors through Entoro’s broker-dealer. All offerings are issued in a Depositary Receipt (DR) format, complete with CUSIP and ISIN for institutional tradability and transparency.

06
Post-Issuance Support

Ongoing servicing is provided by our third-party vendors, including custody, delivery, reporting, and optional integration with secondary trading venues.

For Buyers

Turn Environmental Outcomes into Real Assets

CLEAN offers a reliable path to invest directly in measurable climate and ecosystem outcomes, without the uncertainty and fragmentation of traditional environmental markets.

Balance Sheet Recognition

Unlike expensed offsets, CLEAN securities can be treated as real assets, supporting corporate disclosure, audit requirements, and financial reporting.

Legal and Regulatory Clarity

Every offering is backed by a host country Letter of Authorization (LoA), ensuring jurisdictional legitimacy and enforceability across borders.

Standardized Format

Securities are structured with CUSIP/ISINs and investor-grade documentation, enabling comparability, transparency, and simplified due diligence.

De-risked Access

By using a securitized structure, CLEAN eliminates the buyer-side complexity of credit procurement, double counting, and unclear ownership.

Who Should Consider CLEAN Securities:

With every link in the value chain under one roof, Entoro eliminates fragmentation, accelerates time-to-market and reduces cost of capital for natural-capital projects—while giving investors institutional-grade access to nature-backed returns.

Why Now

The environmental finance landscape is rapidly shifting. As voluntary carbon markets face growing scrutiny over credibility, compliance-grade alternatives are gaining momentum. At the same time, institutional investors are demanding standardized, transparent, and legally enforceable environmental assets. CLEAN was built for this moment.

Climate & Environmental Impact

CLEAN securitizations directly finance projects that deliver measurable, high-integrity environmental outcomes. Every issuance is grounded in discipline, legal structure, and real-world performance.

  • Verified Impact: Projects must meet baseline criteria including additionality, third-party verifiability, and jurisdictional authorization via a Letter of Authorization (LoA).
  • Broad Coverage: Supported outcomes include carbon removal, methane abatement, biodiversity restoration, water purification, regenerative agriculture, and more.
  • Capital to Scale: By turning impact into tradeable securities, CLEAN unlocks institutional capital for scalable climate solutions, not one-off credits.
  • Integrity First: The CLEAN framework enforces strict accountability and transparency, raising the bar for environmental finance beyond the voluntary carbon market.

CLEAN turns environmental ambition into credible, financeable action.
