While many studies show benefits to 30 km/h speed limits, I would take the study's findings with a large grain of salt.
This is published in Sustainability. The article has not been properly peer reviewed. When someone publishes in Sustainability it's a big red flag.

I'll dive into one example of the problem with the paper/data - Paris.

@BrentToderian@mastodon.online Here's the quote on Paris: "Several months after the implementation of this measure, a 25% decrease in the number of bodily injuries and a 40% decrease in serious and fatal crashes was achieved" The source says "The new measure aims mainly to improve road safety and reduce noise pollution. Lowering the authorised speed on the roads allows, on average, to reduce the number of bodily injuries by around 25%. This reduction can reach more than 40% for serious and fatal crashes. "
