The San Joaquin Valley of California is known for its production of nice wine. But did you know it is also know for its production of bad air pollution? Well believe it or not, the San Joaquin Basin is one of the dirtiest in the nation, and its 109 vintners are cited for creating many smog-forming chemicals during fermentation. Fortunately a free market approach to solving this problem has been implemented, and San Joaquin wineries are given the helpful option of either reducing their own emissions, or paying other local industries such as dairies to reduce theirs, if the wine makers find that making changes in their production processes prove too expensive. This market-based solution suits the taste buds of many California wineries.
