Piraeus Port Authority's (PPA) 2013 environmental flyer calls itself the "Green Port of the Mediterranean Sea".[44] The port is a member of EcoPorts.[45] It is also ISO 14001 Certified by Lloyd's Register and Bureau Veritas.[45] PPA states on its website that it has disposal services for all types of ship-generated waste.[46] The port conducts water quality tests and works with nearby schools.[47]
The port has partnered with the University of Piraeus and Cardiff University to implement a sea water quality monitoring program. Bi-annually, the water and sediment throughout the whole port area is sampled and tested.[47] Some parameters measured include pH, Turbidity, Salinity, Biochemical Oxygen Demand (BOD), Chemical Oxygen Demand (COD), E-Coli, Total Coliforms, TDS, and Heavy Metals.[44]
For air quality monitoring, the port partnered with the National Technical University of Athens School of Chemical Engineers. An air quality monitoring station was installed to take measurements of BTEX, CO, NOx, Sulfur dioxide, Ozone, and PM2.5 and PM10, 24 hours a day. PPA has also collaborated with the Agricultural University of Athens to enhance the greenery around the port for aesthetic purposes, as well as to remove pollutants from the air.[47] The purposes of the monitoring initiatives so far has just been for data collection.
In 2004 for the Athens Olympic Games, a permanent sewage network was built for the cruise ships that were docked in Piraeus as floating hotels.[46] The sewage travels to the Wastewater Treatment Plant of Athens.[46] This development allows all cruise ships to be able to discharge sewage at the port.
PPA is a member of EcoPorts. As part of EcoPorts, the port has been continuously Port Environmental Review System (PERS) certified since 2004.[48] PERS is a standard for port environmental management. One of the requirements of EcoPorts is an environmental management system.[49] The port has an oil and Hazardous and Noxious Substances (HNS) contingency plan.[50] In 2016, PPA was independently tested to make sure pollution levels were within legal limits, which they were.
The port is currently looking into LNG as a bunker fuel, as well as cold ironing for the cruise terminals.[51] It is also conducting a footprint assessment. A green roof was installed on the top of one of the new container terminal buildings.[47]
