VEGA Model Documentation

VEGA (Vessel Economic Guidance and Assessment) is a Python-based companion tool of the ICCT’s Polaris model, designed to estimate and compare the net present value (NPV) or total cost of ownership (TCO) of different shipowner renewal choices across years and policy assumptions.

VEGA was first developed in 2025-2026 by Gabe Hillman Alvarez, Jakob Schmidt, Zhihang Meng, and Hae Jeong Cho.
