Musk declared in 2018 that climate change was the most significant threat humanity would face this century.

But then more recently, he's said that farming doesn't contribute. https://x.com/elonmusk/status/1672793968587702272

He flies on his private jet all over the world, that alone contributing 100s of times more than the average household. https://www.theguardian.com/environment/2023/nov/20/elon-mus...

His social media platform is one of the largest spreaders of climate change misinformation.

He recently campaigned for and spent hundreds of millions to elect a guy who believes climate change is a hoax, which will likely delay any progress we could make by years. https://www.businessinsider.com/elon-musk-260-million-spendi...

His unelected, unofficial government department is targeting huge cuts to the EPA. https://www.eenews.net/articles/epa-in-elon-musks-crosshairs...

So maybe in the past he was concerned about climate change, but that appears to no longer be the case, or its further down on his list, below accumulating billions in wealth and amassing political power.
