Denver`s Driving Change Program Reduces Vehicular CO2 Emissions

Telemetry technology and Internet-Based Greenhouse Gas management system
supported pilot program which reduced idling more than 35% and CO2 emissions 10%
DENVER--(Business Wire)--
Driving Change, the world`s first Internet-based vehicular greenhouse gas (GHG)
tracking system, today announced significantreductions in GHG emissions by the
City and County of Denver as a result of online feedback on how driving
behaviors impact the environment and fuel costs. In March 2008, Denver launched
a pilot test of Driving ChangeTM which uses telemetry technology to send vehicle
operating information over the Internet to a GHG management system that provides
each participating driver with individualized, online emissions and driving
dashboards. These dashboards provide drivers with details of their carbon
dioxide (CO2) emissions, a breakdown of driving habits that cause excess carbon
emissions, including idling and aggressive driving events (hard braking, fast
starts), and the cost of excess fuel consumed.

There are 160 City vehicles and 240 citizen vehicles that have participated in
the pilot. According to the United States Environmental Protection Agency, motor
vehicles are the fastest growing source of CO2. It has been estimated that GHG
from vehicles accounts for 30% of the City and County of Denver`s total carbon
footprint. The GHG management system was provided by Enviance, Inc., a
California based company, and the telemetry was provided by Cartasite, Inc., a
Denver-based company. In addition to having 30 employees participate in Driving
Change, Denver-based EnCana Oil & Gas (USA), Inc (NYSE: ECA) underwrote the
program.

Findings from the Driving Change Denver pilot program demonstrate that:

* Measurement improves performance: From May through November, there was a 10%
overall driving improvement in participating vehicles in Denver (as measured by
CO2/mile). This includes reductions in engine idling, fast accelerations and
fast stops.
* Tracking driving behavior has a great impact on engine idling: From May
through November, idling decreased by more than 35% among participating
vehicles, which equates to a reduction of 5 minutes of idling (or a little less
than 1 pound of CO2) per vehicle, for every hour of operation.
* Driver education works: As Driving Change participants were educated in the
program`s goals and tracked their results, they became more likely to turn their
vehicles off. For example, participating Denver drivers provided with more
extensive education reduced engine idling more than 40% through the end of
November.

According to Denver Mayor John Hickenlooper, "Once the Driving Change system
revealed and quantified the idling issue, we were able to use the system to
target the problem and measure our success in reducing this wasteful practice,
allowing us to reduce greenhouse gas emissions and save money on fuel at the
same time."

"Driving Change is another example of Mayor Hickenlooper`s efforts to make
Denver a truly sustainable city. We are honored to have provided the telemetry
technology that made it possible to extend GHG management to the automobile,"
said David Armitage, CEO and President of Cartasite, Inc.

"Having provided the first Internet-based GHG management system to the
commercial sector in 2005, it is exciting to prove that the GHG management power
of the Enviance System can be extended to tackle vehicular GHG," said Lawrence
Goldenhersh, CEO and President of Enviance. "Through his leadership, Mayor
Hickenlooper has provided the world with an important insight on how biofeedback
and the Internet can be combined to tackle the GHG. And with idle time reduced
35%, the gasoline savings amounts to hundreds of thousands of dollars per year
for a fleet of 2000 vehicles confirming that what`s good for the planet is also
good for the bottom line."
