The Hollywood star is leading the Footprint Coalition, an investment fund that seeks to support environmentally-friendly businesses, and Downey Jr is keen to use his platform to highlight climate change issues to his social media followers.
He told the BBC: "I realised a few years ago that I'd amassed a pretty wide audience, I guess you call them followers nowadays. And it seemed like just posting more videos of me dancing with my alpaca wasn't really moving the conversation on this existential threat."
The 'Iron Man' star - who is one of the best-paid actors in the movie business - admitted that the California wildfires in 2918 have proven to be a turning point in his own attitude towards climate change.
He said: "I had my hoses out trying to help my neighbour not lose his house. You kind of go - this is not the rhythm that was going on in California in the 80s or the 90s."
Downey Jr hopes to use his celebrity influence to cut across political divides in the US and elsewhere.
He said: "I think there's a way to appeal to my brothers and sisters in the heartland and my conservative friends, rather than saying, you're wrong, you're crazy and you're bad."
Meanwhile, Downey Jr previously advocated using artificial intelligence (AI) to help tackle climate change.
The actor thinks AI could make a huge difference in helping to "clean up the planet".
Speaking in 2019, Downey Jr explained: "Between robotics and technology, we could probably clean up the planet significantly, if not entirely, within a decade."
