Xcel Energy customers in Colorado will soon be able to check their household carbon emissions online via Xcel’s website. The company may also offer more in-depth carbon calculation tools to help customers determine the total size of their carbon footprint, including emissions produced by food, water and transportation, according to the DenverPost.com.

"What we’re trying to do is help customers understand first what a carbon footprint is and then to give them the information so they can figure it out for their energy usage," said Teddi Davis, Xcel director of customer choice and renewable marketing. "Customers may choose when they have that information to use less energy as a way to make personal choices around their carbon footprint."
