One of the more surprising outcomes of Rio+20 was the focus on natural capital culminating with the signing of the Natural Capital Declaration by 39 global financial institutions. They committed to work to develop methodologies to value and account for nature’s vital role in the global economy.

At the Rio conference, I heard a great deal of conversation about natural capital and ecosystems services -- quite surprising since, until not that long ago, it had been largely the domain of academics -- from company execs, bankers, and others. It seemed to be an underlying theme at several events.

Here's what a couple of the people I talked to had to say, in a video produced by GreenBiz Associate Editor Kristine Wong.
