Suez, now called GDF Suez (the utility completed a merger in July with Gaz de France), boasts an entire division that's dedicated to sustainable development. At the head of the group is a steering committee composed of senior managers from the company's different business units, who work together to implement the company's vision across its branches.

In the fall of 2007, Suez partnered with Volvo to build the world's first carbon dioxide-free car factory, which is powered by wind, biomass, and solar energy. The division's business group forged an agreement to build the water supply system for France's first "eco-neighborhood," Limeil-Brévannes.

Suez, a newcomer to the Accountability Rating this year, also continues to promote its main line of business, natural gas, which is cleaner than oil.
