Environmental sustainability is "absolutely key" to the strategy of Coca-Cola Enterprises, the world's top soft-drink distributor. "It's center of play. It's not niche anymore," says CEO John Brock. The company is focused on water stewardship, packaging and energy conservation and now owns 142 large-scale, hybrid electric trucks -- the largest such fleet on the planet. "And we are buying, literally, as many as we can get, as fast as we can get them," he says.
