CO2 Calculation
Hans Buch offers CO2 calculation and analysis of ships’ energy consumption. We identify potential savings, reduce CO2 emissions and optimise operations through documented analyses and specific recommendations.
CO2 calculation provides an overview of potential savings
A CO2 calculation provides a detailed picture of where a ship’s energy consumption and emissions can be reduced. By analysing the largest energy consumers, it becomes possible to prioritise investments that both reduce CO2 emissions and lower operating costs.
What does a CO2 analysis cover?
A CO2 analysis is based on the ship’s total energy consumption and identifies the areas with the greatest potential for savings. Depending on the vessel type and its operation, the analysis may cover:
- LED lighting
- Steam consumption
- Electricity consumption
- Onboard energy consumption
Our analysis uses the ship’s expected service life, average operating profile and key operating parameters to calculate total CO₂ emissions. Based on these data, we identify specific opportunities for optimisation that reduce both emissions and operating costs.
Typical areas with potential for savings
- Electricity consumption: Optimise lighting and energy consumption with efficient solutions such as LED technology.
- Steam: Energy-saving steam control to achieve the optimum temperature in the cascade tank.
- Water consumption: Optimise the ship’s water management and reduce waste with modern RO systems.

How to improve your ship’s performance
We offer a free, no-obligation analysis that provides a comprehensive overview of where your ship can reduce energy consumption and CO2 emissions. The result is specific recommendations that can improve operational reliability, lower operating costs and reduce the environmental footprint.
A professional CO2 calculation makes it possible
Once the analysis is complete, you receive a documented basis for decision-making that shows where investments will have the greatest impact. The analysis highlights expected energy savings, reduced CO2 emissions and the areas where optimisation can deliver the greatest financial benefit. The results give shipping companies and ship operators a solid basis for prioritising investments and documenting the impact of energy efficiency improvements that have been implemented.
Investment case and payback
In addition to the CO2 calculation itself, Hans Buch prepares an investment case that provides an overview of the expected energy savings, CO2 reductions and estimated payback period. This makes it easier to prioritise investments, document their impact and establish a basis for decisions on future energy efficiency improvements.
