The Download: spying on the spies, and promising climate tech

This is today’s edition of The Download, our weekday newsletter that provides a daily dose of what’s going on in the world of technology.

Meet the man hunting the spies in your smartphone

In April 2025, Ronald Deibert left all electronic devices at home in Toronto and boarded a plane. When he landed in Illinois, he bought a new laptop and iPhone. He wanted to reduce the risk of having his personal devices confiscated, because he knew his work made him a prime target for surveillance. “I’m traveling under the assumption that I am being watched, right down to exactly where I am at any moment,” Deibert says. 

Deibert directs the Citizen Lab, a research center he founded in 2001 to serve as “counterintelligence for civil society.” Housed at the University of Toronto, it’s one of the few institutions that investigate cyberthreats exclusively in the public interest, and in doing so, it has exposed some of the most egregious digital abuses of the past two decades.

For many years, Deibert and his colleagues have held up the US as the standard for liberal democracy. But that’s changing. Read the full story.

Three climate technologies breaking through in 2026  

—Casey Crownhart 

Happy New Year! I know it’s a bit late to say, but it never quite feels like the year has started until the new edition of our 10 Breakthrough Technologies list comes out. 

For 25 years, MIT Technology Review has put together this package, which highlights the technologies that we think are going to matter in the future. This year’s version has a bunch of climate and energy picks including sodium-ion batteries, next-generation nuclear, and hyperscale AI data centers. Let’s take a look at what ended up on the list, and what it says about this moment for climate tech. 

This story ran in The Spark, our weekly newsletter all about the technologies we can use to combat climate change. Sign up to get it in your inbox first every Wednesday. 

And, if you’re keen to learn more about why AI companies are betting big on next-gen nuclear, join us for an exclusive subscriber-only Roundtable event on Wednesday January 28 at 2pm ET.

Quote of the day

“Women and girls are far more reluctant to use AI. This should be no surprise to any of us. Women don’t see this as exciting new technology, but as simply new ways to harass and abuse us and try and push us offline.”

—Clare McGlynn, a law professor at Durham University, tells The Guardian she fears that the use of AI to harm women and girls is only going to grow.

Inside the little-known group setting the corporate climate agenda

As thousands of companies trumpet their plans to cut carbon pollution, a small group of sustainability consultants has emerged as the go-to arbiter of corporate climate action.

The Science Based Targets initiative, or SBTi, helps businesses develop a timetable for action to shrink their climate footprint through some combination of cutting greenhouse-gas pollution and removing carbon dioxide from the atmosphere. After years of small-scale sustainability work, SBTi is growing rapidly, and governments are paying attention. 

But while the group has earned praise for reeling the private sector into constructive conversations about climate emissions, its rising influence has also attracted scrutiny and raised questions about why a single organization is setting the standards for many of the world’s largest companies.
