Energy Efficiency

Shipping is the most efficient means of cargo transportation. However, in abso­lute terms, greenhouse gas (GHG) emis­sions from global shipping are signifi­cant and are rising due to the increase in global trading of goods. Greenhouse gases – carbon dioxide (CO2) methane (CH4) – trap the infrared radiation re­leased by the earth’s surface and keep the planet warmer at a temperature of 33°C (91°F). The increase in CO2 from human-induced activities is widely ac­cepted to increase the earth’s tempera­ture. CH4 has approximately 21 times the global warming potential of CO2.

Capital-Executive’s strategic objective is to preserve its industry-leading position on climate change by combining energy efficiency improvements in current operations with investments in research and technology to reduce the carbon footprint of new vessels.

Energy efficiency measures onboard and ashore

We apply a series of technical and operational improvements both onboard our vessels and at shore, to improve our energy performance and reduce our environmental footprint.
