The company said in a statement that its "vessel performance management and maintenance strategy have been pivotal in ensuring that its operations stay efficient and thus green.
"Through continual improvements in operational efficiencies, fleet and voyage optimisation, as well as the deployment of a fuel-efficient and environmentally-friendly fleet of vessels, APL has successfully lowered its fleet carbon dioxide emission levels annually."
Moving forward, the carrier aims to reduce carbon dioxide emissions per container transported by 30 per cent between 2015 and 2025.
It also plans to persist with cold-ironing development and pioneer ballast water treatment development, by "embracing technology innovation, clean energy sources and best practices".
Said APL chief executive Nicolas Sartini: "Through collaborative opportunities, we seek to help APL shippers design and manage their green supply chain."
