Finland bans cargo ships from discharging wastewater in Finland's coastal waters. While generally a good move, I'm afraid this will become a law only in letter. It will be very difficult to enforce this law as it will hard to even spot the act in the first place, or to tie it to a specific vessel. Also it will be much cheaper to just dump your wastewater in international waters before entering the coastal area. News: https://yle.fi/a/74-20131006 (in english)
