This new stock index aims to track green efforts in emerging markets

One of the top premises behind the Green Revolution has long been that companies embracing green strategies to minimize energy consumption and carbon emissions benefit from "a triple bottom line" (as explained by TriplePundit.com). Such companies win in terms of social costs, environmental benefits and financial gain.

For instance, WalMart isn't going green only to look good among yuppie customers but also because it saves the company that Sam built boatloads of cash over time by reducing electricity, fuel and packaging costs.
