Reports can be generated in four languages, numerous currencies and units of measure. "This was designed for global corporations, using any unit of measure, any currency," Harris says. "All conversions are done automatically by the system."

Because the system is Web-based, companies need not install software--all that's necessary is a browser, Harris notes. Thus, the system is compatible with Windows, Mac and other operating systems. The data can be entered into the system in three ways: by the client, using data from the utility bills; outsourcing data entry to Johnson Controls; or by allowing Johnson to work directly with the utilities to receive the data electronically. The last, Harris notes, may not be allowed in some countries. Only the company and a customer service rep will have access to the data, which will be held indefinitely.The type of data to be entered depends on what the system will monitor.

"If you're using it for energy management, typically we'll want all the data on the bill," Harris says. "For greenhouse gases, we need not just consumption, but the energy source and locations."

Different areas derive their energy from a different blend of sources, he explains, so the portion derived from GHG-producing sources must be factored into the total usage. Once the baseline is established, Johnson provides consulting services that will help companies reduce their energy use and costs, Harris added. Some companies, he notes, are surprised by how well they're doing.

In addition, companies will be able to show stakeholders that they are trying to be socially responsible by reducing emissions and costs. "Wherever you start, it's important to have a public goal to communicate to your stakeholders," Harris says.

Companies subscribe to the service annually. Pricing depends on the number of modules being monitored and the number of buildings being included, but a very large company might pay $30,000 per year. Consulting services are additional fees beyond that.

The Energy and Emissions Management system currently manages $1 billion of annual energy spent and annually monitors 63 million metric tons of greenhouse gas emissions for 5,000 buildings located in 88 countries. Over the last eight years, the system has captured more than 8,000 energy and cost savings initiatives, Johnson says, resulting in savings of $1 billion and 6.2 million metric tons of CO2 or the equivalent.

A company need not be the size of a Pfizer, however, to benefit, Harris said. "It was designed for global corporations," he notes. "But the same features can be used by smaller companies."
