By many measures, Santa Monica is one of the greenest cities in America. It has a strong sustainable city program that includes ambitious environmental, economic and quality of life goals and objectives. It has tough and effective water quality and water supply programs. Its alternative fuels fleet policy has generally been excellent. And city leaders have developed and approved a very tough ordinance that banned single use polystyrene packaging. And for the last three years, they have talked about banning plastic bags. And talked. And talked.
