Coffee is up to 20% heavier before roasting, resulting in millions of tons of unnecessary coffee crossing the world's oceans every year.
Making matters even worse, this cargo often crosses the same oceans more than once.
The environmental impact of shipping includes air pollution, water pollution, acoustic, and oil pollution. Ships are responsible for more than 18 percent of some air pollutants including greenhouse gas emissions. There are now over 100,000 transport ships at sea, of which about 6,000 are large container ships.
Germany, for example, recently re-exported over 323 thousand tonnes (€854 million) of green un-roasted coffee in one year.
Around 98% of German imports of green coffee comes from developing countries and about one -third of this is directly re-exported, the majority sent back to sea, across the Atlantic Ocean, to the USA.
Not only are we shipping up to 20% of the world's coffee unnecessarily, we are re-shipping the exact same cargo with a blatant disregard for the environment.
The International Maritime Organization (IMO) estimates that carbon dioxide emissions from shipping were equal to 2.2% of the global human-made emissions in 2012 and expects them to rise 50 to 250 percent by 2050 if no action is taken.
