Copemer is a leading international bunker broker with a global portfolio of trusted suppliers delivering the highest level of service for the marine industry.

With over 40 years of experience, Copemer facilitates the transactions between bunker suppliers and ship owners or charterers. Recognised for our personal and responsive client care, we support our clients in creating bespoke solutions to cater to their exacting needs at ports worldwide. 

Copemer was founded in Paris by the late André Demart whose work and integrity were recognised by all. We endeavour to continue Mr. Demart’s legacy going forward as well as uphold his personal core values of organisation, precision and adaptability.

Furthermore, in 2021, Copemer started looking into a solution for offsetting Carbon and came across a method to absorb CO2 using Kelp which is a very efficient way and cleans the ocean.

The shipping industry produces 30% of the global CO2 . The IMO (International Maritime Organization) has adopted mandatory measures to reduce emissions by 40% of GHG (Green House Gases) by 2030.

We are now working with farmers to grow and harvest kelp for various products, such as plastic, fiber, as an energy source, and so on.



As a business we aim to collaborate with you and be considered an in-house extension of your company where we can offer advice, information and service whenever you need.

Our team of multilingual bunker brokers is ready to serve you 24/7 and will respond to your enquiry within 24 hours.

Natasha Yamamura

Bunker Broker & Managing Partner

My name is Natasha and I joined Copemer in 2013 as a Bunker Broker and later became the Managing Partner with Olivia.

I completed the M.I.S.E program while working at A.P. Moller Maersk Group in a number of specialties, including container export, reefer-container marketing, and line management.


After leaving Maersk, I graduated from ESCP Europe in London and Paris with a Master’s in Business Administration. I then joined Copemer.


I have over 10 years experience in shipping and brokerage and I believe that my friendly demeanour and hard-working nature will support you in booking your bunker with ease.
