Shipping’s Carbon Bill Could Be Much Higher Than Forecasts

The shipping industry is increasingly finding itself in the crosshairs of climate regulation. The European Union’s Emissions Trading System (ETS) is one such mechanism, a cap-and-trade scheme that imposes a cost on carbon emissions for a growing number of maritime voyages. The logic is straightforward: make polluting expensive, and operators will eventually seek cleaner alternatives.

However, the actual financial impact of these evolving carbon costs is proving to be a complex and often underestimated variable. The prevailing models tend to project a linear progression of carbon prices, assuming a steady, predictable rise. This approach, while convenient, overlooks the inherent volatility and the potential for sharper, more unpredictable cost escalations. There is a certain dark comedy to the market’s collective sigh of relief when projections suggest a manageable carbon bill, as if regulatory bodies would prioritise predictability over the imperative to decarbonise at speed.
