Maersk Sustainability Report: Relative CO2 Down 9% in One Year
- Relative CO2 is down 17 percent from 2010 to 2013, with a 9 percent reduction since 2012.
- Shipping division Maersk Line has improved its carbon efficiency by 34 percent since 2007, and by 12 percent since 2012.
- The company says Maersk Line is well on its way to achieving its 40 percent CO2 reduction target by 2020.
- In 2013, Maersk Line cut carbon by deploying fewer, larger vessels and sailing at more fuel-efficient speeds.
- The first four out of 20 energy efficient Triple-E vessels on order joined Maersk Line’s fleet in 2013.
- Previous estimates have found that these 18,000 TEU vessels could improve CO2 efficiency by 50% per container compared to the industry average on the Asia-Europe trade lane, and early performance figures are in line with these estimates.
- More than half of Maersk Line’s fuel consumption comes from vessels leased from third parties. In 2013, performance on energy efficiency was integrated into the contracting process for charter vessels, and fuel efficiency levels are now an integral part of the selection process, the company says.
- As a result, it deselected a number of suppliers in 2013.
- In 2013, Maersk had one significant spill, defined as a category 2 spill (out of 5) in the group’s spill category matrix, as well as a number of smaller spills.
- In APM Terminals Algeciras in Spain, 7 cubic meters of oil were spilled into the harbor after a container punctured during loading. Maersk says the oil was promptly recovered.
- The number of Maersk Drilling spills fell from 36 in 2012 to 25 in 2013, but the total volume rose by about 3,000 liters, to 23,150 liters.
Ballast water, and water consumption
- Maersk Line and Maersk Tankers do ballast water exchanges midway through their journeys, but say this measure will not suffice in light of anticipated regulatory developments.
- In preparation for when regulations enter into force, the group says it has ensured that all ships delivered in 2012 and beyond are equipped with ballast water treatment systems.
- It estimates that the IMO’s Ballast Water Management Convention will cost the group up to $550 million over the next six to seven years.
- The company’s water consumption fell to 2.52 million cubic meters in 2013, from 2.55 in 2012 and 2.37 in 2011.
SOx and NOx
- In 2013, the group’s SOx and NOx emissions decreased, primarily due to reduced fuel consumption (see chart).
- Maersk notes that international regulations are set to lower the caps for these emissions from sea vessels.
- Waste output fell to 379,000 metric tons in 2013, from 391,000 in 2012 and 447,000 in 2011.
Data and reporting
- The report was prepared using the GRI G4 Sustainability Reporting Principles.
Takeaway: The report shows the company making good progress on CO2 intensity and reducing its water, waste, SOx and NOx impacts, although some relative figures would have helped to put those cuts in context.
