Live Earth Concert-Goers Can Go Neutral with Esurance

Auto Insurance Company Works with Live Earth and NativeEnergy to Offset CO2

SAN FRANCISCO, June 29 /PRNewswire/ -- Esurance, the direct-to-consumer personal auto insurance company, announced its plans to offset the carbon dioxide emissions of those driving to the Live Earth concert in New Jersey on July 7, 2007. The CO2 offsets will be provided by NativeEnergy, a privately held Native American energy company that helps build Native American, farmer-owned, community-based renewable energy projects to create social, economic, and environmental benefits.

John Swigart, CMO of Esurance, stated, "First and foremost, we want our support to help make Live Earth, the largest green event of its kind, as green as possible. The best solution for reducing CO2 on July 7 would be for concert-goers to take public transit. However, we recognize that some people will still need to drive to the event. Esurance is proud to work with NativeEnergy to offset the CO2 emissions generated by driving."

The day of the concert, those who drive to the Live Earth concert in New Jersey will be directed to www.esurance.com/sos to enter their mileage to and from the event. After collecting this information over a two-week period, Esurance will purchase an amount of CO2 offsets from NativeEnergy to carbon neutralize the reported travel. NativeEnergy's current offset projects include a variety of wind farms, along with farm methane projects. Such projects provide renewable, clean energy service on behalf of NativeEnergy's customers, while also benefiting the communities that operate them.

"Though Live Earth focuses a spotlight on the challenge of global warming, attendee travel to such events unavoidably contributes to global warming. The leadership demonstrated by Esurance helps build awareness of the solutions available to offset carbon emissions from travel and other daily energy uses," noted Tom Boucher, President & CEO of NativeEnergy.

Swigart concluded, "As an auto insurance company, Esurance helps protect you from the bad things that can happen to your car. We're also proud to help protect the environment. CO2 emissions from automobiles are a problem we can all work together to solve."
