What to know about River shipping emits nearly one-quarter of global shipping CO₂, analysis finds

A report on a study published in Nature Climate Change indicates that river and canal shipping accounts for approximately 24.7% of global shipping CO2 emissions. The research utilized a route reconstruction model to analyze 20 billion ship-tracking records from 2019 to 2022, finding that a small number of major rivers contribute the majority of these emissions.

Why it matters

And that's despite the fact that these bodies of water make up less than 1% of Earth's total navigable waterways.

Common ground

Overlooked pollution source Cars, planes and ocean-going vessels contribute considerably to global transport pollution.

Perspective signals

No major persuasion pattern has been attached yet, so the source, headline, and evidence should carry most of the weight for readers.
