farms, commercial transportation, and related business activities. (This does not include the indirect emissions associated with imported products or raw materials.) U.S. businesses had about 136.7 million employees in 2006, so that's roughly 40 tonnes per employee. You can do a first approximation of your firm's emissions.

40 tonnes CO₂e per employee

These emissions came mainly from the following sources associated with your business:

• Generation and delivery, or on-site generation, of electricity, steam and process heat you used in your operations, including offices and production.
• Transportation used by your employees to get to and from their jobs.
• Energy embodied in water, paper and other supplies used at your facilities.
• Combustion of liquid fuels at your sites.
• Delivery of raw materials to yourfacilities.
• Distribution of finished products to your customers.
• Emissions from waste from your offices and production sites.
• Business travel by your employees, including sales calls.

The exact mix of where CO₂e is emitted in your business requires some analysis. You also want to identify "low hanging fruit"—energy uses where reducing CO₂e emissions is easy. There are consultants who can help you do this, and we are compiling a list. But in the meantime you might try this walkthrough approach outlined by The Carbon Trust (pdf copy on our site). Often the wasted energy spotted in such a walkthrough can amount to 10-20% of total energy use in a building. That goes to the bottom line. And it reduces greenhouse gas emissions immediately. These early savings may pay for professional assistance with more complicated analysis. You're on your way.
