T&E said that European Parliament had also recently voted in favour of emissions caps.
Environmental groups are continuing a push to have emission targets placed on the shipping sector, having announced in a statement that Members in the European Parliament (MEPs) have also voted in favour of such a move at the Paris climate summit later this year.
World leaders are expected to settle on a global climate deal in December, with one large aspect being a potential emissions cap on both the shipping and aviation sectors.
Environmental activist group Transport & Environment (T&E) said that European Parliament had agreed that it would be odd for the shipping sector to be exempt from limits when countries must adhere to targets.

The Parliament has sent a clear message to the EU
"The Parliament has sent a clear message to the EU and all negotiators at Paris; the aviation and shipping sectors need emissions reduction targets too, so there is no reasonable excuse to continue exempting them," said Sotiris Raptis, shipping policy officer at T&E.
"You just can't have a global deal to combat climate change without capping the growing emissions from international aviation and shipping, which have CO2 emissions equal to those of the UK and Germany respectively."
T&E has been vocal about the idea of emissions targets in recent months, though the International Maritime Organization has appeared to disagree.
Last month, Ship & Bunker reported that IMO Secretary-General Koji Sekimizu had urged world leaders to decide against a cap because of the risk it would pose to the shipping economy.
