Besides speaking out for the re-election of President Barack Obama, President Bill Clinton this week is campaigning vocally for causes that are of particular interest to sustainable investors.

This morning the Clinton Global Initiative, founded by the former president in 2005, announced the launch of The Foundation for Sustainable WasteResources, formed to address the growing health and environmental crisis caused by billions of tons of waste produced worldwide. The announcement came at the initiative's eighth annual meeting in New York.

The foundation's first effort will be to create an interactive map and database of global waste sites and systems. In developing regions, open dumping is used to get rid of most waste, with most money spent on collecting garbage and only a fraction directed toward disposal.

The Foundation for Sustainable WasteResources plans to create an interactive global map of waste management systems that will identify key locations of significant amounts of waste around the world. Focusing on these mapped-out areas, the foundation will then bring together stakeholders in the waste management sector, including waste pickers, developers and governments, with the hope of creating solutions and converting waste into valuable resources.

Also this morning, Clinton called on Wal-Mart to open a store in Libya to help create jobs, according to the Huffington Post. The former president raised the question while moderating a panel that included Wal-Mart's CEO Mike Duke.
