CE Deft compares CO2 emissions of MARPOL Annex VI two compliance options in 2020 — report

CE Delft compares CO2 emissionsCE Deft, the environmental research organization based in the Netherlands, published its report comparing CO2 Emissions of the two options used for compliance with the new MARPOL, Annex VI, emissions regulations that went into effect January 1st, 2020.

“MARPOL, the main international convention preventing pollution from ocean-going vessels, sets limits on the sulphur content of the fuel oil they burn. Under Regulation 14 of MARPOL Annex VI, as of January 1st, 2020 the maximum permitted sulphur content of fuel oils used outside Emissions Control Areas (ECAs) is 0.50% m/m. Inside ECAs, the limit has been 0.10% m/m since 2015.

In practice, there are two options for compliance with this regulation:

  1. using an Exhaust Gas Cleaning System (EGCS) in combination with fuel oils with a sulphur content over 0.50% or 0.10%, respectively
  2. using fuel oil with a maximum sulphur content of 0.50% (VLSFO) or 0.10% (ULSFO).”

“The conclusion of this study is therefore that well-to-wake CO2 emissions increase in both options.”
