Every container that crosses an ocean carries two weights: the cargo inside and the carbon it leaves behind. We make the second number smaller.

Dr. Nadia Osei-Mensah
Lead — Maritime Decarbonization
Ph.D. Naval Architecture, TU Delft. Former technical advisor, IMO Marine Environment Protection Committee. 14 years modeling vessel emissions across 22 flag states.
Most shippers inherit emissions estimates from their forwarder's spreadsheet — a number that won't survive a CSRD audit. We rebuild the calculation from AIS vessel-track data, fuel consumption logs, and verified CII ratings, producing a defensible well-to-wake figure for every trade lane you operate.
AIS Track Analysis
Pull actual vessel trajectories for your shipments — not port-to-port great-circle estimates.
CII Rating Cross-Reference
Map each vessel against current IMO CII scores to flag regulatory exposure in your carrier pool.
Fuel-Type Attribution
Distinguish HFO, VLSFO, LNG, and methanol shares using bunker declarations and charter party terms.
Scope 3 Category 4 Allocation
Allocate emissions to your consignments using mass, TEU, and distance — GLEC Framework compliant.
Scope 3 Playbook — Maritime Chapter
Includes CII exposure calculator, carrier scorecard template, and sample CSRD disclosure language.
Modal shift fails when the carbon argument is disconnected from the cost argument. We model both simultaneously: emissions reduction, transit time delta, inventory carrying cost, and service reliability — giving your logistics team a single document to put in front of finance and sustainability together.
Lane Emission Intensity Ranking
Identify the 20% of lanes generating 80% of your road freight emissions.
Alternative Mode Feasibility
Map rail, intermodal, and short-sea options against your transit time constraints and DC network.
Total Cost of Ownership Model
Include modal premium, inventory buffer, and service failure probability in a single TCO comparison.
Carrier Negotiation Briefing
Prepare RFQ language and service-level thresholds for modal transition conversations.
Scope 3 Playbook — Modal Shift Chapter
Includes lane emission intensity workbook, intermodal feasibility matrix, and CFO presentation template.

LL.M. Environmental Law, King's College London. Certified GHG Protocol Lead Verifier. Advised 30+ companies through their first CSRD double-materiality assessments.
The difference between a disclosure that satisfies auditors and one that impresses investors is specificity. We build your Scope 3 transport reporting infrastructure from the ground up — carrier data templates, verification protocols, and the narrative layer that translates emission intensity numbers into strategic positioning.
Double-Materiality Assessment
Determine which transport emission topics are material under ESRS E1 for your sector and revenue band.
Carrier Data Collection Protocol
Deploy standardized data request templates to your top 20 carriers — compliant with GLEC and EN 16258.
Assurance-Ready Documentation
Structure your methodology notes, data sources, and assumptions to survive limited assurance review.
Narrative Disclosure Drafting
Write the ESRS E1 transport section in plain language that satisfies auditors and communicates to investors.
Scope 3 Playbook — CSRD Reporting Chapter
Includes carrier data request template, ESRS E1 disclosure checklist, and sample assurance-ready methodology note.
EV fleet transition fails when it's treated as a procurement decision rather than a network design problem. We model charging infrastructure requirements, grid capacity constraints, and route optimization simultaneously — producing a phased transition roadmap that reduces both Scope 1 emissions and total cost of ownership within 36 months.
Drayage Lane Electrification Scoring
Rank your last-mile lanes by EV feasibility: range, payload, dwell time, and depot charging potential.
Charging Infrastructure Sizing
Model depot charging load against local grid capacity and utility tariff structures.
TCO Crossover Analysis
Calculate the month at which EV total cost of ownership crosses below diesel — by vehicle class.
Phased Procurement Roadmap
Sequence vehicle replacements to maximize incentive capture and minimize operational disruption.
Scope 3 Playbook — EV Transition Chapter
Includes drayage electrification scoring matrix, charging infrastructure calculator, and 36-month transition roadmap template.
