Emission ‘Sniffers’

Norway is growing its arsenal of military grade drones for missions that will take them into the exhaust stream of ship’s funnels.

With the IMO now supporting the 0.05 percent sulfur cap on marine fuel from Jan. 2020, and with southern Norway below the 62nd parallel of? cially a European

Emissions Control Area, or ECA, the Norwegian Maritime Authority, the NMA, is cracking down on illegal sulfur emissions.
