> we began enforcing reduced sulfur emissions from diesel motors in international waters. The expectation was that would help with climate change, how couldn't it Nice story, but the drive to reduce SOx and other particulate emissions is not because of climate chance but because of localized health concerns: because of the respiratory impact of SOx and soot to the lungs of people on coastlines and in port cities. By the way, Dieselgate is a similar story - the illegally-increased SOx, NOx and particulate emissions of those diesel engines were created in order to decrease fuel consumption and thus climate change impact. Cracking down on Dieselgate helped people living near the car exhausts but hurt the climate as a secondary effect...
