In summary, it sounds like you're saying (and please correct me if I'm missing it - I don't want to put words in your mouth) that we just need big corporations to come up with innovative ways to go green which are cheaper than the traditional ways. And that we shouldn't be coercing corporations into "going green", we need them to do it on their own.
I mean, yeah, that all sounds good, but how do you do it?
Personally, I don't think there is a way to get everybody to cooperate when there are such big benefits to defecting. I think you need regulations.
The non-libertarian FAQ has a great example of why you'll never see that altruistic, cooperative behavior emerge out of mutual self-interest:
Coordination problems are cases in which everyone agrees that a certain action would be best, but the free market cannot coordinate them into taking that action.
As a thought experiment, let's consider aquaculture (fish farming) in a lake. Imagine a lake with a thousand identical fish farms owned by a thousand competing companies. Each fish farm earns a profit of $1000/month. For a while, all is well.
But each fish farm produces waste, which fouls the water in the lake. Let's say each fish farm produces enough pollution to lower productivity in the lake by $1/month.
A thousand fish farms produce enough waste to lower productivity by $1000/month, meaning none of the fish farms are making any money. Capitalism to the rescue: someone invents a complex filtering system that removes waste products. It costs $300/month to operate. All fish farms voluntarily install it, the pollution ends, and the fish farms are now making a profit of $700/month - still a respectable sum.
But one farmer (let's call him Steve) gets tired of spending the money to operate his filter. Now one fish farm worth of waste is polluting the lake, lowering productivity by $1. Steve earns $999 profit, and everyone else earns $699 profit.
Everyone else sees Steve is much more profitable than they are, because he's not spending the maintenance costs on his filter. They disconnect their filters too.
Once four hundred people disconnect their filters, Steve is earning $600/month - less than he would be if he and everyone else had kept their filters on! And the poor virtuous filter users are only making $300. Steve goes around to everyone, saying "Wait! We all need to make a voluntary pact to use filters! Otherwise, everyone's productivity goes down."
Everyone agrees with him, and they all sign the Filter Pact, except one person who is sort of a jerk. Let's call him Mike. Now everyone is back using filters again, except Mike. Mike earns $999/month, and everyone else earns $699/month. Slowly, people start thinking they too should be getting big bucks like Mike, and disconnect their filter for $300 extra profit...
A self-interested person never has any incentive to use a filter. A self-interested person has some incentive to sign a pact to make everyone use a filter, but in many cases has a stronger incentive to wait for everyone else to sign such a pact but opt out himself. This can lead to an undesirable equilibrium in which no one will sign such a pact.
The most profitable solution to this problem is for Steve to declare himself King of the Lake and threaten to initiate force against anyone who doesn't use a filter. This regulatory solution leads to greater total productivity for the thousand fish farms than a free market could.
The classic libertarian solution to this problem is to try to find a way to privatize the shared resource (in this case, the lake). I intentionally chose aquaculture for this example because privatization doesn't work. Even after the entire lake has been divided into parcels and sold to private landowners (waterowners?) the problem remains, since waste will spread from one parcel to another regardless of property boundaries.
