When looking at the #climate change and global warming, maritime transport is efficient with the lowest Co2 emission (with train) per tonne of product : One average size container ship represents the equivalent of 1,000 Airbus A380 aircraft or 6,000 trucks for the same transported quantity
– We should be satisfied …. but as usual, the situation is not so simple: Vessels use fuel with high level of particles (worst than old diesel car) - the generated air pollution is huge, sulphur oxide (SOx) and nitrogen oxide (NOx) are released in our air and is harmful for human health.
In addition, most of the #packaging of the good transported is not optimised, at least 20% of wasted space resulting in shipping air instead of product.
Around 80% of world trade in terms of volume is carried by sea, and this share is expected to grow considerably in the near future. To reduce the impact on the environment, our priority should be focused on 3 main issues:
Stop transporting air, reduce invisible waste (#wastedSpace) and save cost.
Buyers to look at the clean shipping index (CSI) or environment shipping index (ESI) as they do now for FSC or PEFC for fibres.
Invest in cleaner energy for ships: alternative fuels, hybrid and renewable energy sources are studying.
Point 1 depends on industry & company who buy the goods and need to work with vendors, suppliers and manufacturers. Improving #packaging and designing optimised dimension with the relevant inserts are part of the solution.
Point 2 is up to any buyer of shipped goods, ask for the index and prefer vendors with the right performance.
Point 3 is starting and depends on shipbuilding industry, countries regulation and maritime organisation. EU strategy & regulation: Large ships over 5 000 gross tonnes loading /unloading cargo/ passengers from 1 January 2018 at EU maritime ports are to monitor and later report their related CO2 emissions. Initial IMO (international maritime organisation) strategy on reduction of GHG emissions and air pollutants from ships has been adopting in April 2018.
