Observation of Global Change Annual Changes in tropospheric NO 2 Nitrogen dioxide observed has changed over last decade Nitrogen dioxide observed has changed over last decade Downward trend over Europe, upward over China Downward trend over Europe, upward over China “Spy in the sky” like observation of global pollution changes “Spy in the sky” like observation of global pollution changes China originally had very low numbers officially for pollution, now actively engaged in monitoring and reduction programmes China originally had very low numbers officially for pollution, now actively engaged in monitoring and reduction programmes

NO 2 emissie van schepen Richter et al., GRL, 2004 Scheeps-emissies significant Emissions from ships are already now comparable to emissions from the other transport sectors. Global Shipping is assumed to significantly grow during the next decades. No or weak international regulation
