Ahti Climate

Ahti Climate, based in Helsinki, Finland, is a digital platform committed to making the green transition in shipping both cost-effective and accessible. Built around the innovative Ahti Calculator and Ahti Pool, the company uses data science and digital technology to help shipowners, charterers, fuel suppliers, and fuel producers optimize compliance with the EU’s FuelEU Maritime regulation by minimizing emissions-related costs. Its tools enable users to compare alternative fuels, assess the economic and environmental trade-offs, and benefit from pooling strategies—such that just 1–1.5% of e-methanol combined with pooling can outperform traditional heavy fuel oil without penalties. Trusted by industry players like Gasum and Ren-Gas and powering over 250 vessels, Ahti Climate transforms regulatory complexity into strategic advantage for the maritime sector.
