The Download: cleaning up shipping, and Elon Musk’s new AI startup
This is today's edition ofThe Download,our weekday newsletter that provides a daily dose of what's going on in the world of technology.
How common chemicals could help clean up global shipping
Global shipping is a big deal for the climate, accounting for 3% of the world's greenhouse-gas emissions. Last week saw a big news announcement from the International Maritime Organization, the UN agency in charge of regulating the vessels that carry the goods we buy all over the world.
On July 7, the IMO agreed to new climate goals, setting a target date of by or around 2050" to clean up the industry's act and reach net-zero emissions. There are checkpoints too: emissions should be at least 20% below 2008 levels by 2030.
The shipping industry hasn't had targets like this before. So how does it reach them? It's more doable than you might think, as our climate reporter Casey Crownhart explains. Read the full story.

Quote of the day
I look a little bit askance at signing a six month pause while you're trying to accelerate your own effort."

The big story
Predictive policing algorithms are racist. They need to be dismantled.
Inequality and the misuses of police power don't just play out on the streets or during school riots. For digital rights activists, the focus is now on where there is most potential for long-lasting damage: predictive policing tools and the abuse of data by police forces.
A number of studies have shown that these tools perpetuate systemic racism, and yet we still know very little about how they work, who is using them, and for what purpose. All of this needs to change before a proper reckoning can take place, but a clear principle is emerging: if we can't fix them, we should ditch them. Read the full story.
