NYK has become the first Japanese shipping company to complete a carbon-neutral voyage. NYK did this by offsetting 5,000 tons of carbon dioxide (CO2), equivalent to the CO2 emitted by NYK’s environmental flagship car carrier Aries Leader during one voyage between Japan and the Middle East.
Aries Leader is equipped with the latest energy-saving technologies, reducing CO2 emissions per unit by 30% compared with existing large pure car carriers (i.e., comparing emissions on a per car basis).
The remaining CO2 emissions not yet eliminated by technology have been offset by carbon credits to allow NYK to realize carbon-neutral voyage that theoretically reduces CO2 emissions to zero.  NYK purchased the carbon credits from a wind power project in West India.  The project supplies about 375 GWh of clean electricity annually and supports the rapidly increasing electricity demand in India.
This initiative demonstrates the ability of NYK to provide carbon-neutral transportation to its Japanese and overseas customers, thus meeting the demand for a more sustainable, carbon-free supply chain.  NYK will propose and expand its carbon offsets to customers as an option that benefits the environment and contributes to a zero-carbon-footprint supply chain.
The company will continue its efforts to provide shipping services that meet customer needs, as well as create new green businesses through carbon credit initiatives and realize the company’s basic philosophy of “Bringing value to life.”
Changing from heavy oil to liquefied natural gas (LNG) would result in emissions reductions of about 30% for CO₂, about 80% for NOx, and 100% for SOx.
In October 2011, the NYK Group established its Fuel Project Team to research the viability of a fuel changeover and the development of related technology.
In August 2015, the first domestic LNG-fueled tugboat was completed.  And in September 2016, two dual-fuel LNG pure car and truck carriers (PCTCs), a world’s first, were completed.  These vessels have a dual fuel engine that can use either LNG or heavy oil as fuel.
