15 Biggest Cruise Ships In The World Greenhouse Gas Emissions

Shipping currently accounts for 2-3 of global greenhouse gas emissions but a 2014 UN study warned increasing trade could up.

15 biggest cruise ships in the world greenhouse gas emissions. Cargo ships are a major source of non-CO2 greenhouse gases as well many of which are associated with eroding human health. Although international aviation and shipping each account for less than 35 of the EUs total greenhouse gas emissions they have been the fastest growing sources of emissions that contribute to climate change. Greenhouse gas emissions from international aviation have more than doubled over the past two decades while those from shipping have also increased.

Further the 15 largest ships in the world emit as much nitrogen oxide and sulphur oxide as the worlds 760 million cars. Germanys CO2 and overall greenhouse emissions account for about 22 and 19 of the worlds total respectively according to European Commissions most up-to-date figures -. The emissions from 15 of these mega-ships match those from all the cars in the world.

The megacity of Shanghai China is one of the worst emitters of greenhouse gases on the planet Shutterstock Over half of all the urban greenhouse gas. One of the eight longest container ships in the world the 1300 ft Emma Mærsk also has the worlds largest reciprocating engine. Dr Steve Gration a GCAN member from Australias Gold Coast said the worldwide shipping industry produces over 3 of the planets greenhouse gases including carbon dioxide methane and nitrous oxide.

As such cruise. The Harmony owned by Royal Caribbean has two four-storey high 16-cylinder Wärtsilä engines which would at full power each burn 1377 US gallons of fuel an hour or about 66000 gallons a. By burning heavy fuel oil just 15 of the biggest ships emit more of the noxious oxides of nitrogen and sulphur than all the worlds cars put together.

Ships are responsible for more than 18 percent of some air pollutants. Shipping accounts for somewhere between 2 and 3 of global greenhouse gas emissions its often compared to Germany in terms of the scale of emissions. Most are in the Middle East.

Again this is measured in tonnes of carbon dioxide equivalents. Bunker fuel can have a. In its annual report on cruise ships the German environmental group Nabu says the industry is not doing its part to minimize.
