Project Story
This project involves integrating a Climatenza T160 parabolic trough solar thermal field into the existing hot-water network at the LDC Mombasa facility. The system aims to preheat water from the return header (~110u00b0C) to the supply temperature (~120u00b0C), thereby displacing HFO fuel used in the Thermax SMW2000 boiler. The solar field, located on a 3,550 mu00b2 site with five candidate zones, is designed to generate approximately 4,787 GJ of useful heat annually, achieving a solar fraction of about 79%. The project leverages coastal DNI conditions, with a peak thermal output of 805 kW, and is expected to reduce HFO consumption by 135 tons per year, cutting associated COu2082 emissions by 382 tons annually.

What is this card?
The Verified Impact Data Card summarises the key environmental and assurance metrics for this project. Data is pulled live from VCS assessments and on-chain commitments.
How to read the data
- Emissions Reduction — Estimated annual CO2e avoided or removed, derived from the project's VCS methodology and baseline scenario.
- Overall Score — Composite VCS readiness score (0–100%) covering additionality, permanence, leakage, and MRV quality.
- REC % — Alignment with Renewable Energy Certificate issuance criteria.
- EEC % — Alignment with Energy Efficiency Certificate criteria.
- Phase — Current stage in the project development lifecycle.
- DePIN Integrity — Data integrity score from decentralised sensor network (uptime, calibration, completeness).
Glossary
- VCS — Verified Carbon Standard (Verra), a leading carbon credit certification programme.
- tCO2e/yr — Tonnes of carbon dioxide equivalent per year.
- VVB — Validation/Verification Body, the independent auditor that reviews project claims.
- Evidence Tier — Classification of supporting evidence quality (e.g. Tier 1 = measured data, Tier 3 = default factors).
- Commitment Hash — Cryptographic hash of the assessment data committed to blockchain for tamper-proof audit trail.
- DePIN — Decentralised Physical Infrastructure Network, providing real-time sensor-based MRV data.
- Scope 3 Cat. 15 — GHG Protocol category covering financed emissions from investments.

Methodology
Forecast outlook: Conservative/Base/Optimistic scale the 2035 multiplier path and apply a sale-realisation haircut; small discount-rate nudge reflects risk.
REC pricing: V-REC/GO/I-REC converted to selected units (MWh or tCO₂e-eq via EF) and currency; tier factor applies to REC/EEC classes.
Financials: All internal calculations in the selected currency. Annual net flow = (credit revenue × (1−haircut) + optional savings) − O&M. KPIs: IRR (Newton-Raphson), NPV and discounted payback at your rate.
Currency handling: Capex, O&M and savings are all in the selected currency. Credit prices are converted from their native currency via ECB rates.
Standards & Registries
Primary standards: Verra (VCS) & Gold Standard. Tool is Verra-first but surfaces Gold Standard context where relevant.

VCS Readiness Assessment
Summary
The project demonstrates comprehensive technical documentation, including detailed GHG quantification, monitoring, and risk assessments, indicating strong preparedness for VCS validation. However, critical safeguards, stakeholder engagement, and additionality demonstration are notably lacking, which could impede full VCS compliance.
