Forget biodiesel. To put a dent in global warming, we are going to have to stop using coal, said Ed Mazria, founder of Architecture 2030 at the West Coast Green conference taking place in San Francisco this week.”The only fossil fuel that can fuel global warming is coal. If you stop coal, you stop global warming. End of story,” he said. Architecture 2030 is a non-profit that encourages builders, suppliers and architects to move toward making carbon neutral buildings by 2030.
