Hi there, a project of ours, sustainablevaluecalculator.com, is now in public beta. The website introduces a new model for calculating corporate sustainability - so probably less interesting to the general public, but I still hope we've done a good job in making it easy to understand and follow. The site revolves around a calculator you can use to assess a company's performance against a number of benchmarks.
The application is built with Zend Framework and jQuery. Make sure to try the guided tour of the calculator. I'd really appreciate any comments before we publically launch the site. Thanks, Bernd
