Slow steaming, sails, batteries, LNG -- none of it would make us be carbon-neutral.

慢速航行、风帆、电池、液化天然气——没有一个能让我们实现碳中和。

That was done by building bigger and more efficient vessels, and by slow steaming, which means sailing the vessel slower so it consumes less fuel.

这是通过建造更大、更高效的船只和慢速航行来实现的，这意味着船只航行得更慢，因此消耗更少的燃料。
