Azipod® propulsion

This calculator showcases the estimated reduction of CO2e emissions as a result of powering a vessel with Azipod® propulsion compared to a similar vessel powered by shaft line propellers and is based on typical scenarios calculated for cruises, yachts, ferries, and offshore vessels. This calculator could also be applicable for other vessels with a similar operational profile.

Why ship owners should invest in cleaner operations

As ship owners navigate the evolving maritime landscape, reducing emissions isn’t just a choice - it’s a strategic imperative due to several key reasons, including the following:

  1. Regulatory compliance
    First of all, stricter environmental regulations are being enforced globally and compliance with emission reduction targets is essential to avoid penalties and maintain operational licenses.
  2. Market reputation and stakeholder expectations
    Secondly, as sustainability practices are increasingly valued by stakeholders, ship owners and operators who actively reduce emissions enhance their reputation, attract environmentally conscious clients, and meet investor expectations.
  3. Cost efficiency and fuel savings
    Thirdly, implementing emission reduction measures leads to energy efficiency, which implies cost savings due to lower energy consumption.
