Enter Software as a service (Saas). Vendors such Environmental System Corp (ESC) are poised to deliver Saas for EPA GHG reporting, but also provide a means for utilities to have easy access to their data. ESC's product - CIMVision-GHG Manager - creates an XML file to upload into the EPA system and allows utilities to access their compliance data by facility and source. The software also includes tools like a compliance calendar to track compliance milestones and deadlines, the ability to create compliance tasks and e-mail notifications and a document repository. Emissions can be either calculated based on fuels or derived using Continuous Emissions Monitoring Systems (CEMS) data. Over 150 of ESC's utility customers are now using CIMVision to get a view into GHG emissions. ESC has a leg up in connecting with the CEMS as its customer base is almost entirely utility companies that need to comply with the EPA's Part 75 CEMS reporting requirements with templates that allow for quick configuration and calculation of GHG emissions.

Another alternative to choose from is IHS. IHS offers its Greenhouse Gas and Energy Management Solution as either an installed or hosted solution. A hosted solution is different from Saas as it is a one to one vs. a one-to-many Saas. IHS's software can be deployed to help companies manage any kind of greenhouse gas management program, voluntary or regulatory. IHS's GHG MRR solution also creates an xml file for the different MRR Subparts that can be loaded into the EPA system. In addition, users can calculate indirect emissions from the supply chain or from energy consumption of equipment. As well, IHS a set of built-in connections with facility process data management systems and CEMS installations

There is a move in the U.S. Congress to limit EPA's jurisdiction over GHG. Whether that move will succeed is still in question, although many utilities welcome having some definitive regulation in this area so that they can plan going forward. There are also utilities that, regardless of regulation, will be looking to improve their carbon footprint and sustainability record. In contrast, Europe has a more clear direction on emissions with the EU Emissions Trading Scheme (ETS). With the events surrounding the nuclear plant in Japan, the price of carbon has risen to around 17 Euros per ton, as the markets see more use of fossil fuel for generation.

Despite the activities of Congress, these reporting deadlines are still expected to hold. Of course, since this reporting applies to 2010, utilities will have to have already been tracking emissions starting January 1, 2010. It is not too early to start working with a vendor to automate reporting. While there may be some adjustments to the XML schema for reporting, these are not expected to be major and vendors should be able to accommodate these without extra charge.
