Mark, The report at http://www.nj.gov/dep/opppc/reports/early1.htm is old but good and includes cost-benefit numbers for NJ's materials accounting program and I think highlights the real business values of materials accounting data. NJ has other, recent data on its website, http://www.nj.gov/dep/opppc/reports.html#p2 . Regards, Melinda Dower NJDEP >>> Mark Snyder <snyde043 at gmail.com> 10/20/2009 11:46 AM >>> Hi all, I'm researching a question posed to us by one of Minnesota's state legislators about materials accounting data. Basically, she's wondering whether Minnesota should follow New Jersey's and Massachusetts' leads in requiring such data from manufacturers and other industrial facilities. What I'm looking for is any evidence that such a requirement leads to greater progress in pollution prevention than in states like Minnesota that only require Toxic Release Inventory data reporting. Anyone have any leads they can share with me?
