CO2 Surge at Sea: The Environmental Toll of Redirection in Maritime Routes Amid Red Sea Crisis

The Red Sea attack crisis has led to continued rerouting of vessels through the Cape of Good Hope, which has not only altered the dynamics of global shipping but has also unveiled an environmental consequence —a surge in carbon emissions.

Earlier, when the crisis started, and the vessels started rerouting, Portcast predicted and informed about the possible increase in carbon emissions, specifically focusing on the South Asia region (India/Colombo) to Europe and the US East Coast.

South Asia Region to Europe: A 50% Surge in CO2 Emissions

Traditionally, vessels from South Asia to Europe have relied on the Suez Canal, a critical shortcut that significantly reduces travel distances and emissions. Portcast's calculations reveal a staggering 50% increase in carbon dioxide emissions for shipping between the South Asia region and Europe. 

South Asia Region to US East Coast: A 20% Rise in CO2 Emissions

The impact is not confined to the European routes alone; vessels between the South Asia region and the US East Coast have also experienced a notable increase in carbon emissions.

Portcast's data indicates an approximate 20% surge in CO2 emissions for shipping between the South Asia region and the US East Coast. 

Impact of Redirection on Critical Routes

Recent findings from Portcast shed light on the stark increase in CO2 emissions for shipping routes between China, Singapore, Malaysia, and Europe, as well as the US East Coast.

  1. Singapore/Malaysia to Europe: CO2 emissions increased by 40%.

  2. Singapore/Malaysia to US East Coast: CO2 emissions rose by 16%.

  3. China to Europe: CO2 emissions saw a 30% increase.

  4. China to US East Coast: CO2 emissions increased by 12%.

[Note: Various factors influence CO2 emissions, and these figures represent a general trend observed by Portcast.] A report from Portcast posted on February 02, 2024.
