Tony Stark made the ultimate sacrifice to save the world in Avengers: Endgame, and now the man who portrayed him is doing his part as well. Robert Downey Jr. announced he is helping launch a new initiative to save the planet.

Business Insider reports Downey appeared at the Machine Learning, Automation, Robotics and Space (MARS) conference in Las Vegas and spoke as the keynote speaker.

The room Downey commanded was full of AI designers, astronauts and other scientific minds. Sure, he only plays Tony Stark, one of the smartest men in the Marvel Cinematic Universe, but he is a funny guy with a legitimate plan.

After leading the crowd through jokes and stories from the MCU, Downey revealed he is launching a new initiative called the Footprint Coalition. Downey admitted he didn't understand all the scientific parts of the problems or solution, but he wanted to help the planet anyway.

"Recently, I was at a table with super smart, impressive, expert folks about six months ago, and the following statement was made: 'between robotics and technology, we could probably clean up the planet significantly, if not entirely within a decade,'" Downey said.

Downey admitted that it will be hard to get past the government and bureaucratic roadblocks, but he wants to try to do it anyway. He also revealed the Coalition will launch in April 2020.

"I've got to do something. I'm unemployed," Downey told the crowd, bringing up Tony Stark's death in Endgame.
