It's hardly the fault of capitalism that lots of people do not believe in human responsibility for climate change. I wouldn't advise to force people into complying with your vision.
The point here is that it does't matter if they believe or not. Capitalism does not let them stay true to their beliefs.
Businesses that act in a sustainable way will not be as competitive as businesses that don't. So, it's very hard to be sustainable in a capitalism system that doesn't "price in" the externalities of the natural world that we've been taking for granted.
You can use the same example for globalization and offshoring of jobs. If I'm a business owner who manufactures cheap things, it doesn't matter how much I care about keeping my factory in the US or Europe because other factories will go to where the labor is cheapest and out compete me. So, I'm forced to do it too just to compete.
That's still not the fault of capitalism, but of the people opting for the cheapest solution. To introduce change, some kind of force would be required, which I strongly advise against. As soon as the self-interest of all actors is concerned things will change on their own.
