Tachyus has a GHG product called Aurion.  Aurion is an off-the-shelf software that has effectively productized the greenhouse gas EPA reporting process. Additionally, it has made general tracking, benchmarking and forecasting much easier. The main differentiator is their ability to integrate data and forecast out at the individual facility level. This allows companies to get their GHG data on demand and run what-if analysis/forecasts allowing for operational decisions that have a material impact on emissions.
