CO2 emitted by world’s largest container lines continued to fall in 2018, as new larger vessels boost the sector’s energy efficiency
Carbon dioxide emissions from the world’s largest container lines continued to fall during 2018, as new larger vessels boost the sector’s energy efficiency.
Emissions from 17 of the world’s leading ocean container carriers, representing about 80% of global containerised shipping, have declined by 9.6% since 2015, despite an increasing number of vessels in service, according to a report by Clean Cargo, a freight forwarding forum.
The aggregate average trade lane CO2 emissions factors are compiled from data reported by more than 3,200 ships.
Since Clean Cargo began publicly reporting data from the industry in 2009, emissions per container per km have dropped 41.2% on average for dry cargo, the report said.
“While changes in carrier representation or global trade conditions likely explain a portion of these results, the continued performance improvement is also attributable to carrier fleet efficiency and data quality, both of which have direct benefits for shipping customers,” it added.
Data from the forum’s members indicate that larger and newer vessels still account for the majority of environmental performance variations. However, an increasing number report that they are putting into effect energy efficiency and energy management measures.
“With growing exposure of climate impact and increased societal and regulatory expectations, decarbonising ocean shipping is no longer an impossible dream but a real business continuity challenge,” said Clean Cargo programme director Angie Farrag-Thibault. “While consolidated and comprehensive emissions data is one key part of this effort, system change through value-chain collaboration is also critical.”
Clean Cargo developed a standardised methodology and reporting system that was adopted globally by the industry, with carriers submitting operational data from the entire fleet on an annual basis for trade lane emission factors aggregation.
The results produce environmental performance scorecards for each carrier, which are used to meet corporate supply chain sustainability goals by a significant share of shipping customers participating in the group.
