Emission from shipping increasing

At least according to EU study:

Was listen to to a BBC radio in the EU 2 years back and they were interviewing a scientist from a swiss lab that the UN and other funds that have been long term measurements of pollution in the lower atmosphere.
He said many chemicals exist in the atmosphere that were banned years ago and some are going up but not sure where they are being made.
Many restricted chemicals are also going up where there is control of output.
He didnt have any good news.
