IMO Approves First Global Carbon Levy on Shipping
In April 2025, the International Maritime Organization voted to approve the IMO Net-Zero Framework — the first time an entire industry has set a legally binding price on carbon emissions at a global scale. Green Gate is built to help African states capture their share of this revenue.

Two-Tier Carbon Pricing
The IMO framework establishes carbon prices of $100 and $380 per metric ton of CO₂ equivalent, with transferable tax credits. Green Gate's configurable tax rate engine supports any pricing tier.
GFI Registry Integration
A new IMO GFI Registry tracks each ship's annual greenhouse gas fuel intensity. Green Gate's AIS tracking and emission calculations feed directly into GFI reporting requirements.
Compliance Monitoring
Ships must report their attained annual GFI to the IMO. Green Gate provides real-time compliance monitoring against IMO CII benchmarks, ensuring sovereign states can enforce the framework.
International Legal Framework
Overview of all applicable international regulations governing maritime carbon taxation and emission accountability.
Green Gate Sovereign Framework
Maritime Environmental Levy applicable to all commercial vessels transiting or anchoring in Somaliland Exclusive Economic Zone (ZEE). Based on polluter-pays principle.
Key Requirement
Payment prior to Clearance issuance at Port of Berbera.
Clearance denied / vessel detained pending payment.
IMO Carbon Intensity Indicator (CII)
Annual rating system (A–E) measuring CO₂ emitted per cargo carried over distance. Ships rated D or E for 3 consecutive years must submit corrective action plans.
Key Requirement
Annual CII rating submission to flag State.
Mandatory corrective action plans; operational restrictions for low-rated vessels.
IMO MARPOL Annex VI
International convention to minimize airborne pollution from ships. Sets limits on SOx and NOx emissions and mandates Energy Efficiency measures (EEXI, EEDI).
Key Requirement
SULFur cap: max 0.5% sulfur fuel globally; 0.1% in ECAs.
Port-State Control detention; fines by flag State.
EU Emissions Trading System — Maritime
As of 2024, large ships calling at EU ports must surrender EU Allowances (EUAs) for 40% of their verified CO₂ emissions (scaling to 100% by 2026).
Key Requirement
Annual surrender of EUAs matching verified emissions.
€100 per tCO₂ not covered, plus public reporting of non-compliance.
Paris Agreement — Art. 6 (Carbon Markets)
Establishes cooperative approaches for countries to meet NDCs through carbon credit trading. Green Gate aligns sovereign carbon offsets with Article 6.2 and 6.4 mechanisms.
Key Requirement
Corresponding adjustments to avoid double-counting of carbon credits.
Non-recognized credits cannot be used for NDC compliance.
This regulatory overview is for informational purposes only. Green Gate operates under the Somaliland Sovereign Environmental Framework and recognizes all applicable international conventions. Vessel operators should consult their flag State and legal counsel for definitive compliance obligations.
