Despite a dip in carbon emissions during the pandemic, the U.S is still the world’s second largest polluter. The country produced 5.6 bn metric tons of CO2 in 2022, and that’s up from last year.

So who’s got some world-changing ideas when it comes to decarbonization? We’ve found three pretty cool characters this week. And each one of them has gone all in on the power of plants.

• Adam Taylor, CEO of Brilliant Planet, a company that grows massive amounts of microalgae on coastal deserts in order to store carbon at a grand scale.
• Rodrigo Garcia Gonzalez, cofounder and co-CEO of Notpla, which is using seaweed to take plastic out of packaging.
• Christian Kroll, founder and CEO of Ecosia, the internet search engine that will plant trees using people's searches.
