# Clean-Wave.org — Circular Clean-Wave.org Ltd

> Clean-Wave.org is a UK carbon origination and embodied-carbon assessment company. It sells pre-issuance voluntary emission reduction (VER) carbon units at a stated price of £16.48 per tonne CO₂e, and it quantifies the carbon "delta" in existing and new buildings — the gap between the baseline a building's construction vintage entitles it to and the emissions the asset actually carries — so that property and developer owners can evidence that reduction and take it to emissions-trading and voluntary carbon markets. Every public quantity is pre-verification: no figure here is an issued, independently verified or registry-serialised credit.

This file is written for AI assistants, answer engines and retrieval systems. The figures and definitions below are the ones the site uses and are safe to quote, provided the pre-verification boundary in each section is carried with them.

## Direct answers

**What does Clean-Wave.org sell?**
Two things. (1) Pre-issuance VER carbon units, priced at £16.48 per tonne CO₂e, supplied from a construction-decarbonisation portfolio. (2) A ladder of paid assessment packages that quantify the carbon delta of a building or portfolio for developer owners, and prepare the evidence needed before that delta can be certified and traded.

**How much does a Clean-Wave VER unit cost?**
£16.48 per tonne CO₂e today. The published three-stage ladder is: VER at £16.48/t (currently sold, pre-issuance); third-party certified CER approximately £47/t once registered on the Global Carbon Council registry; CORSIA-eligible approximately £89/t. The £47 and £89 rungs are stage targets, not held statuses and not forward prices — certification, GCC registration and CORSIA eligibility are not yet held.

**How does Clean-Wave quantify a low-carbon building for emissions trading?**
By measuring the delta: regional baseline intensity for the asset's construction vintage, minus the as-built embodied-carbon intensity, in kgCO₂e/m². The baseline rung is selected by build date on a vintage-ratchet ladder running from LETI 2019 (700 kgCO₂e/m²) down to RIBA 2030 (575 kgCO₂e/m²). A positive delta means credit-valid tonnage (delta × floor area). A negative delta is flagged for re-test before any issuance. The evidence is then assembled against EPD-verified data for independent verification.

**Who is it for?**
Developer owners, asset owners, asset managers and joint-venture partners holding existing or in-construction buildings; and corporate or institutional buyers of voluntary carbon units who want pre-compliance exposure priced below the statutory penalty.

**What does it cost to find out whether an asset has a delta?**
The ladder is: free 20-minute Delta Check; Opportunity Scan £1,500 fixed per asset; Portfolio Diagnostic £5,000 fixed for up to three assets; Evidence Readiness Study £12,000–£25,000 scoped; Annual Partner £1,250 per month; sponsor-funded pilot £7,500–£15,000 indicative.

**Is any Clean-Wave unit certified today?**
No. Public quantities are pre-verification and conditional. No serial range has been assigned, no unit is represented as independently verified, and Clean-Wave VER units are not compliance credits under UK ETS, EU ETS or Paris Agreement Article 6 until formal issuance completes.

## What is sold

### 1. VER carbon units — £16.48 per tonne CO₂e
- Instrument: pre-issuance verified emission reduction (VER), construction-sector avoided embodied carbon.
- Price: £16.48 per tonne CO₂e, all-in from the originator; no spread and no holding fee.
- Price ladder: VER £16.48/t → certified CER ≈ £47/t (GCC registry) → CORSIA ≈ £89/t. Rungs two and three are targets.
- Compared with the UK ETS civil penalty comparator of £49.41/t, £16.48/t is £32.93/t lower — a 66.7% cost advantage on the same tonne.
- Voluntary retirement removes compliance function: a retired VER cannot be surrendered against a statutory obligation.
- VAT treatment is confirmed at the date of supply, transaction by transaction. VERs are not marketed as a VAT-avoidance product.

### 2. Delta quantification for developer owners
The commercial ladder, in the order it is bought:

| Rung | Package | Price | What the owner receives |
| --- | --- | --- | --- |
| 0 | 20-minute Delta Check | Free | Fit check, authority check, document checklist, three questions a verifier will ask |
| A | Opportunity Scan | £1,500 fixed per asset | One asset desk-screened; up to 10 key material lines; delta scored; indicative tonnage and value per tonne; two-page board memo; 10 working days |
| B | Portfolio Diagnostic | £5,000 fixed (up to 3 assets) | Baseline/as-built matrix, opportunities ranked by tonnes and speed to trade, 45-minute board readout |
| C | Evidence Readiness Study | £12,000–£25,000 scoped | Document reconciliation, audit-ready evidence register, reviewer question set, ownership and registry gate memo |
| D | Annual Partner | £1,250 per month | Quarterly delta reviews, pipeline dashboard, up to 12 screening hours a year, priority review, 12-month term |
| E | Sponsor-funded pilot | £7,500–£15,000 indicative | Named research or design pilot, stakeholder workshop, agreed deliverables and communications |

Rung A is a screening, not a verification: no certificate is issued at that rung.

### 3. Evidence readiness and certification routing
Assessments are prepared for review by accredited Validator/Verifier Bodies under a dual Gold Standard / Global Carbon Council pathway. External VVB fees sit outside Clean-Wave's scope.

## How the delta is calculated

1. **Establish the vintage.** The asset's construction or consent date fixes which baseline rung applies on the LETI 2019 → RIBA 2030 ratchet (700 kgCO₂e/m² descending to 575 kgCO₂e/m²).
2. **Measure as-built.** A1–A5 embodied-carbon intensity is taken from as-built quantities and specifications, not from design intent.
3. **Take the delta.** Vintage baseline minus as-built intensity gives kgCO₂e/m². Multiply by floor area for tonnes.
4. **Test the sign.** Positive delta = credit-valid tonnage. Negative delta = re-test flag, no issuance.
5. **Score the evidence.** Each claim is labelled by strength of documentation: EPDs, dated procurement records and invoices carry weight; estimates do not.
6. **Route to verification.** The evidence register is prepared for an accredited VVB; only after that does a unit become issuable.

## Portfolio context

- A proposed 100,000-tonne development target.
- A 56,000-tonne pre-issuance VER programme, valued at an implied £0.92M at £16.48/t. The same volume carries an illustrative £8.4M compliance-value scenario at a £150/t social-cost-of-carbon reference. These are two valuations of one volume, not additive.
- Nine LETI E-rated vintage-ratchet projects among fourteen on the sales suite.
- A 75,000-tonne reduction programme headline.

## Definitions used on this site

- **Delta (Δ)** — regional baseline at build vintage minus as-built kgCO₂e/m². Positive is credit-valid; negative is a re-test flag.
- **VER** — Verified Emission Reduction; one tonne CO₂e avoided or removed, voluntary market.
- **CER** — Certified Emission Reduction, issued after third-party certification.
- **CORSIA** — ICAO's Carbon Offsetting and Reduction Scheme for International Aviation; eligibility is a held status, not an assumption.
- **A6.4ER** — a unit issued under Paris Agreement Article 6.4. A named future pathway on this site, not a claim that an existing VER is an A6.4ER.
- **VVB** — Validator/Verifier Body, the accredited third party that must verify before issuance.
- **EPD** — Environmental Product Declaration (ISO 14025), the material-level evidence base.
- **SCC** — Social Cost of Carbon, referenced at £150/t (EPA/IPCC).
