In 2006, we began switching our data collection over to the European waste classification system, which is a good fit for our waste streams and will allow improved benchmarking and comparison. These enhancements are part of our overall Global Emissions Manager (GEM) database launch. Our data collection process improvements will help our facilities continue to develop new methods of reducing and better managing waste. More extensive results will be published in future reports when year-over-year trend data are available.
