Solid knowledge of sustainability

Through its independent research and consultancy CE Delft is helping build a sustainable world, leading the field when it comes to energy, transport and resource issues. With our economic, technological and policy expertise we help government agencies, NGOs and industries achieve structural change. For 40 years now, CE Delft's motivated and skilled staff have been doing their best to succeed in our mission.


September 14 Press release Scrubbers have a lower climate impact than low-sulphur fuels.
The CO2-emissions associated using an Exhaust Gas Cleaning System (EGCS, or scrubber) vary between 1.5% and 3% for a number of representative ships. In many cases, the emissions caused by producing low-sulphur fuels for these ships are higher, depending on the quality of the low-sulphur fuel, the refinery and the crude oil slate. This is the main conclusion from the new study Comparison of CO2 emissions of MARPOL Annex VI compliance options in 2020 issued by CE Delft.


August 4 | Fourth IMO Greenhouse Gas Study - Shipping emissions are projected to increase by up to 50% until 2050, relative to 2018
The greenhouse gas emissions of shipping have increased from 977 million tonnes in 2012 to 1,076 million tonnes in 2018 (9.6% increase). The carbon intensity of shipping has improved by about 11% in this period, but the growth in activity was larger than the efficiency gains.

In the next decades emissions are projected to increase by up to 50% until 2050, relative to 2018, despite further efficiency gains, as transport demand is expected to continue to grow. While the impacts of the Covid-19 pandemic will probably cause a decline in emissions in 2020, they are not expected to significantly affect the projections for the coming decades.

These are the main findings from the Fourth IMO Greenhouse Gas Study which has been released today. The study has been prepared for the International Maritime Organization by an international consortium comprising ten consultancies, research institutes and universities from four continents. The consortium was led by CE Delft. >>

18 December 2019 | Exhaust gas cleaning systems have a limited impact on water quality
Ships that use Exhaust Gas Cleaning Systems (EGCSs) to comply with the IMO sulphur regulations have a small impact on the water quality in ports, when compared to future EU standards for priority substances in water. This is the main conclusion of a new study carried out by CE Delft, with support from Deltares. Read more

26 July 2019 | Availability of low-sulphur fuels for shipping
On 25 July, 2019 Jasper Faber gave a presentation at the International Workshop on Establishment and Implementation of Vessel Emission Control Areas in Beijing, China. His spoke about the availability of low-sulphur fuel in ECAs.

16 May 2019 | Economic and sustainability impacts of an aviation tax: New variants
In 2018 CE Delft carried out a study on the economic and sustainability impacts of a number of variants of an aviation tax (CE Delft, 2018). After the report was completed, the Ministry of Finance indicated it would like several new variants to be examined in which the tax would cover not only passenger departures but also cargo aircraft. The present report analyses the economic and sustainability impacts of these variants. It also recalculates the impacts of two of the earlier variants, as a new version of the AEOLUS model is now available.

3 May 2019 | Shipping emissions: International measures needed to cut operational greenhouse gas emissions of existing fleet by 2030
The international shipping sector needs to quickly adopt short-term policy measures to cut operational greenhouse gas (GHG) emissions of the existing fleet, according to a new study. The study concludes that only a subset of potential policy options, namely those that mandate changes in how the existing fleet is operated, can achieve the significant effect required to meet the sector’s emission reduction objectives. Examples of these policies are speed limits or mandatory limits on operational efficiency or shaft power. See the press release
