Green Shipping | Part 1: Spotlight on carbon dioxide

Green Shipping | Part 1: Spotlight on carbon dioxide

August 2020 | The current Green Deal of the Vogemann shipping company contributes to a more sustainable, environmentally friendly shipping. One aspect that qualifies the Green Ship Token as a Green Deal is carbon dioxide emissions. Here, the Hamburg-based company with a long tradition is already positioning itself as a pioneer in its industry.

When people talk about greenhouse gases, they usually refer to carbon dioxide (CO2). In fact, this gas accounts for the majority of the greenhouse effect. It is mainly produced when fossil fuels such as coal, oil or natural gas are burned – in other words, when electricity and heat are generated, in transport and in industry. Traffic is not the biggest polluter. And certainly not shipping, especially if one compares the quantity of goods transported with the emissions. Airplanes or trucks, for example, emit significantly more pollutants – and carry much less freight per flight than a merchant ship, as the following chart shows. What also emerges from the chart is that Green Dolphins, the design on which Vogemann relies, is characterized by once again significantly reduced values.

Specific CO2emissions of cargo transportation

The share of shipping in global CO2 emissions is therefore relatively small:

Nevertheless, we must of course react, because climate protection concerns us all. 

EEDI: Focus on CO

The indicator for increasing energy efficiency on ships and reducing CO2 emissions in this area is called the Energy Efficiency Design Index (EEDI). It indicates the specific CO2 emissions in grams per ton of cargo and nautical mile travelled.

The goal is to reduce the CO2 emissions of international maritime transport by at least 40% by 2030 and by 70% by 2050 compared to 2008. 

The EEDI must be calculated on a binding basis for all new ships put into service since July 1, 2015. The CO2 reduction targets have been divided into four phases (0 to 3). From the beginning of 2020 until 31.12.2024 we are in phase 1, in which the reduction must be at least 10 percent. After that, phase 2 will apply for another four years with a reduction of at least 20 percent. From January 1, 2029, phase 3 will take effect, in which the reduction must be at least 30 percent. 

Vogemann is the only shipping company already meeting the requirements for 2029

It should be a matter of course to comply with these requirements – and Vogemann takes it for granted. The fight against climate change is probably the greatest challenge facing humanity in this century. At Vogemann not only the acting persons see themselves privately, but also the company itself committed to the climate goals of the Paris agreement.

Already years ago the shipping company Vogemann therefore decided to convert and expand the fleet accordingly towards ultramodern, energy-efficient and low-emission tonnage:

  • The two 38,000 dwt “eco” Handysizebulker newbuildings ordered by Vogemann and delivered in 2017 meet the EEDI Phase 2 standard
  • The two 40,000 dwt “Green Dolphin” Handysizebulker newbuildings “Voge Sophie” and “Sea Eagle” ordered by Vogemann and delivered in 2019 already meet the EEDI Phase 3 standard. They are therefore ten years ahead of the market in terms of climate protection and energy efficiency. By the way, they are the only ships of this class worldwide. 
  • However, they will soon face competition – albeit from within their own ranks: A series of ships of the next “Green Dolphin” generation commissioned by Vogemann at the end of 2019 will also meet the EEDI Phase 3 standard.

There are other greenhouse gases besides CO2. What they do and what makes up the greenhouse effect can be read here. Click here for the kick-off article of the series and here for our article about sulfur emissions.
