I'm speaking on base resource consumption, not emissions. And the main factor for shipping having less emissions is due to mass transit, this is why they say promoting mass transit is better than improving fuel efficiency or emissions in personal vehicles.

In 2019 there are 6.08 Gt from road vehicles compared to the 0.87 Gt from shipping. That's just overwhelming.
