Increasing car's fuel efficiency makes a big impact

 

Narrator:       This is Science Today. Researchers at the University of California, Berkeley have developed a new website that helps households calculate their carbon footprint and create a customized plan for reducing their emissions.

Jones:             We often hear many tips about things we can do to reduce our carbon footprint but very often those aren't the things that lead to the greatest impact.

Narrator:       Energy researcher Chris Jones developed the first version of the carbon calculator in 2005, but recently released a second-generation model that accounts for location, household size and income. According to Jones, it's the combination of these factors that make up a household's carbon footprint.

Jones:             Luckily there are some rules of thumb. While everybody has a unique carbon footprint, a few things really stand out. One is personal vehicles. Increasing the fuel efficiency of your vehicle is one choice and can have as much impact as many, many other choices combined in your lifestyle.

Narrator:       If you want to check your own carbon footprint, the carbon calculator is available online at coolclimate.berkeley.edu. For Science Today, I'm Larissa Branin.
