The "Iron Man" star took the stage Tuesday at Amazon's re:MARS conference in Las Vegas and unveiled the Footprint Coalition, a group that seeks to put robotics and other technology to use toward cleaning up the planet, according to Forbes.
While specifics on the initiative were scarce, the actor has his sights set on implementing major cleanup tools within the next ten years.
“Between robotics and nanotechnology we could probably clean up the planet significantly, if not entirely, within a decade,” Downey Jr. reportedly said.
He has already spoken with experts about the concept and plans to officially launch the project in April 2020.
With a goal to get the venture up and running next spring, Downey said the upcoming months are critical. Right now, he said he's focused on “putting this together correctly and getting actual smart people around me,” according to Forbes.
As Downey talked on stage, images of plastic bottles and other litter flashed on the screens behind him. The actor, who has played Iron Man in several superhero movies, admitted he hasn't been kind to the environment in the past.
"I am a one-man carbon footprint nightmare colossus," he said. "I want to change."
At Amazon’s re:MARS conference, the online retailer and other companies are showing off how they use artificial intelligence and other technology.
