Standards & Accreditations
Emissions accounting follows the GLEC Framework v3.2 (Smart Freight Centre) and ISO 14083 — the international standard for quantifying greenhouse-gas emissions of transport operations. Greensee is a certified Solar Impulse Efficient Solution (2022).

Emissions at berth (hotelling)
The energy a vessel uses while alongside — lights, HVAC, reefer, pumps — supplied by burning fuel in its auxiliary engines plus its boiler. Derived from AIS movement data on an IMO Fourth GHG Study basis and converted to CO₂e using fuel and grid emission factors. This is the baseline, before any shore-power connection.
Avoidable via OPS (shore power)
Onshore Power Supply replaces the auxiliary-engine share with grid electricity. The saving is net of the grid's own carbon, and the boiler load remains on fuel (boilers are hard to electrify). So the avoidable share is not 100%.
Worked example — Shenzhen: baseline 11,157 t = aux 9,461 t + boiler 1,697 t. On OPS, residual 8,520 t = grid 6,823 t + boiler 1,697 t; avoided = 9,461 − 6,823 = 2,637 t (24%).
Fuel-cost saving
MGO at $720/t and 0.225 kg/kWh ≈ $0.162/kWh. OPS tariffs: Guangdong $0.12/kWh, Hong Kong $0.15/kWh. Applied to each terminal's OPS energy potential.
Grid carbon intensity
China Southern Power Grid (Guangdong) 0.52 kgCO₂e/kWh (CSG 2024 OM); Hong Kong CLP 0.37 (2024); EU-27 average 0.23 shown for context. A cleaner grid means OPS abates more.
Performance Index (relative, CPPI-style)
A relative ranking of the three GBA terminals by average time at berth — the core efficiency axis of the World Bank CPPI (less time = better). Index is relative: 100 = best in the GBA. This is an internal proxy, not the official CPPI; time at berth also partly reflects each terminal's vessel-size mix.
Infrastructure
Quay length and STS crane counts provided by Greensee: Shenzhen 7.5 km / 166, Guangzhou 7.4 km / 86, Hong Kong 9,005 m across 4 terminals / 89. Hong Kong is not SMDG-coded, so supplied separately rather than from the SMDG registry. Crane density = cranes per 100 m of quay.
Data sources & scope
Emissions, OPS potential, berth calls and berth-hours: Greensee AIS-derived dataset (IMO Fourth GHG Study basis), Q1 2026 (Jan–Mar), tonnes CO₂e. Container throughput / TEU metrics are out of scope in this view.
