A report by Green Century Capital Management has published a report that grades companies on how they are progressing on phasing out bisphenol-A (BPA) from their products. Some companies, such as Heinz, scored A-grades whilst others, like Coca Cola, failed to reach the mark. Some retailers say they're working hard to go BPA-free. Last year, only 7% of companies had timeliness to phase out BPA. This year, 32% have set timelines, the report says. Most large baby bottle makers already have stopped using BPA.
